Sumatriptan Succinate

Sumatriptan Succinate

The maximum single recommended adult dose of sumatriptan succinate injection is 6 mg injected subcutaneously. If side effects are dose limiting, then lower doses may be used (see Table 1). The maximum recommended dose that may be given in 24 hours is two 6 mg injections separated by at least 1 hour. Controlled clinical trials have failed to show that clear benefit is associated with the administration of a second 6 mg dose in patients who have failed to respond to a first injection.

In patients receiving MAO inhibitors, decreased doses of sumatriptan should be considered (see WARNINGS: Concomitant Drug Use and CLINICAL PHARMACOLOGY: Drug Interactions: Monoamine Oxidase Inhibitors).

Since the injection is intended to be given subcutaneously, intramuscular or intravascular delivery should be avoided. Patients should be directed to use injection sites with an adequate skin and subcutaneous thickness to accommodate the length of the needle.

In patients receiving doses other than 4 or 6 mg, only the 6 mg single-dose vial dosage form should be used. Parenteral drug products should be inspected visually for particulate matter and discoloration before administration whenever solution and container permit.
Coly-mycin S

Coly-mycin S

Therapy with this product should be limited to 10 days. (See WARNINGS.)

The external auditory canal should be thoroughly cleansed and dried with a sterile cotton applicator.

When using the calibrated dropper:

For adults, 5 drops of the suspension should be instilled into the affected ear 3 or 4 times daily. For pediatric patients, 4 drops are suggested because of the smaller capacity of the ear canal.

The patient should lie with the affected ear upward and then the drops should be instilled. This position should be maintained for 5 minutes to facilitate penetration of the drops into the ear canal. Repeat, if necessary, for the opposite ear.

If preferred, a cotton wick may be inserted into the canal and then the cotton may be saturated with the suspension. This wick should be kept moist by adding further solution every 4 hours. The wick should be replaced at least once every 24 hours.
Dantrium

Dantrium

For Use in Chronic Spasticity

Prior to the administration of Dantrium, consideration should be given to the potential response to treatment. A decrease in spasticity sufficient to allow a daily function not otherwise attainable should be the therapeutic goal of treatment with Dantrium. Refer to INDICATIONS AND USAGE section for description of response to be anticipated.

It is important to establish a therapeutic goal (regain and maintain a specific function such as therapeutic exercise program, utilization of braces, transfer maneuvers, etc.) before beginning Dantrium therapy. Dosage should be increased until the maximum performance compatible with the dysfunction due to underlying disease is achieved. No further increase in dosage is then indicated.

Usual Dosage

It is important that the dosage be titrated and individualized for maximum effect. The lowest dose compatible with optimal response is recommended.

In view of the potential for liver damage in long-term Dantrium use, therapy should be stopped if benefits are not evident within 45 days.

Adults

The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient's response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose.
25 mg once daily for seven days, then 25 mg t.i.d. for seven days 50 mg t.i.d. for seven days 100 mg t.i.d.
Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.)

Pediatric Patients

The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient's response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose.
0.5 mg/kg once daily for seven days, then 0.5 mg/kg t.i.d. for seven days 1 mg/kg t.i.d. for seven days 2 mg/kg t.i.d.
Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.)

For Malignant Hyperthermia

Preoperatively

Administer 4 to 8 mg/kg/day of oral Dantrium in 3 or 4 divided doses for one or two days prior to surgery, with the last dose being given approximately 3 to 4 hours before scheduled surgery with a minimum of water.

This dosage will usually be associated with skeletal muscle weakness and sedation (sleepiness or drowsiness); adjustment can usually be made within the recommended dosage range to avoid incapacitation or excessive gastrointestinal irritation (including nausea and/or vomiting).

Post Crisis Follow-up

Oral Dantrium should also be administered following a malignant hyperthermia crisis, in doses of 4 to 8 mg/kg per day in four divided doses, for a one to three day period to prevent recurrence of the manifestations of malignant hyperthermia.
Coly-mycin M

Coly-mycin M

Important: Coly-Mycin M Parenteral is supplied in vials containing colistimethate sodium equivalent to 150 mg colistin base activity per vial.

Reconstitution for Intravenous or Intramuscular Administration

The 150 mg vial should be reconstituted with 2 mL Sterile Water for Injection, USP. The reconstituted solution provides colistimethate sodium at a concentration equivalent to 75 mg/mL colistin base activity.

During reconstitution swirl gently to avoid frothing.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If these conditions are observed, the product should not be used.

Dosage

Adults and Pediatric Patients—Intravenous or Intramuscular Administration

The dose of Coly-Mycin M Parenteral should be 2.5 to 5 mg/kg per day of colistin base in 2 to 4 divided doses for patients with normal renal function, depending on the severity of the infection.

In obese individuals, dosage should be based on ideal body weight.

The daily dose and frequency should be reduced for the patients with renal impairment. Suggested modifications of dosage schedule for patients with renal impairment are presented in Table 1.
TABLE 1. Suggested Modification of Dosage Schedules of Coly-Mycin M Parenteral for Adults with Impaired Renal Function Degree of Renal Impairment Normal Mild Moderate Severe Note: The suggested total daily dose is calculated from colistin base activity. Creatinine Clearance (mL/min) ≥80 50-79 30-49 10-29 Dosage Schedule 2.5 – 5 mg/kg, divided into 2 to 4 doses per day 2.5 – 3.8 mg/kg, divided into 2 doses per day 2.5 mg/kg, once daily or divided into 2 doses per day 1.5 mg/kg every 36 hours INTRAVENOUS ADMINISTRATION Direct Intermittent Administration—Slowly inject one-half of the total daily dose over a period of 3 to 5 minutes every 12 hours. Continuous Infusion—Slowly inject one-half of the total daily dose over 3 to 5 minutes. Add the remaining half of the total daily dose of Coly-Mycin M Parenteral to one of the following:0.9% NaCI5% dextrose in 0.9% NaCI5% dextrose in water5% dextrose in 0.45% NaCI5% dextrose in 0.225% NaCIlactated Ringer's solution10% invert sugar solution
There are not sufficient data to recommend usage of Coly-Mycin M Parenteral with other drugs or other than the above listed infusion solutions.

Administer the second half of the total daily dose by slow intravenous infusion, starting 1 to 2 hours after the initial dose, over the next 22 to 23 hours. In the presence of impaired renal function, reduce the infusion rate depending on the degree of renal impairment.

The choice of intravenous solution and the volume to be employed are dictated by the requirements of fluid and electrolyte management.

Any final intravenous infusion solution containing colistimethate sodium should be freshly prepared and used for no longer than 24 hours.
INTRAMUSCULAR ADMINISTRATION For intramuscular Injection, administer by deep intramuscular injection into a large muscle mass (such as the gluteal muscles or lateral part of the thigh). Store reconstituted solution for intramuscular injection in a refrigerator 2° to 8°C (36° to 46°F) or between 20° to 25°C (68° to 77°F) and use within 7 days.
Ketamine Hydrochloride

Ketamine Hydrochloride

Note: Barbiturates and ketamine hydrochloride, being chemically incompatible because of precipitate formation, should not be injected from the same syringe.

If the ketamine hydrochloride dose is augmented with diazepam, the two drugs must be given separately. Do not mix ketamine hydrochloride and diazepam in syringe or infusion flask. For additional information on the use of diazepam, refer to the WARNINGS and DOSAGE AND ADMINISTRATION Sections of the diazepam insert.

Preoperative Preparations:
While vomiting has been reported following ketamine hydrochloride administration, some airway protection may be afforded because of active laryngeal-pharyngeal reflexes. However, since aspiration may occur with ketamine hydrochloride and since protective reflexes may also be diminished by supplementary anesthetics and muscle relaxants, the possibility of aspiration must be considered. Ketamine hydrochloride is recommended for use in the patient whose stomach is not empty when, in the judgment of the practitioner, the benefits of the drug outweigh the possible risks. Atropine, scopolamine, or another drying agent should be given at an appropriate interval prior to induction.
Onset and Duration:

Because of rapid induction following the initial intravenous injection, the patient should be in a supported position during administration.

The onset of action of ketamine hydrochloride is rapid; an intravenous dose of 2 mg/kg (1 mg/lb) of body weight usually produces surgical anesthesia within 30 seconds after injection, with the anesthetic effect usually lasting five to ten minutes. If a longer effect is desired, additional increments can be administered intravenously or intramuscularly to maintain anesthesia without producing significant cumulative effects.

Intramuscular doses, in a range of 9 to 13 mg/kg (4 to 6 mg/lb) usually produce surgical anesthesia within 3 to 4 minutes following injection, with the anesthetic effect usually lasting 12 to 25 minutes.

Dosage:

As with other general anesthetic agents, the individual response to ketamine hydrochloride is somewhat varied depending on the dose, route of administration, and age of patient, so that dosage recommendation cannot be absolutely fixed. The drug should be titrated against the patient's requirements.

Induction:

Intravenous Route:

The initial dose of ketamine hydrochloride administered intravenously may range from 1 mg/kg to 4.5 mg/kg (0.5 to 2 mg/lb). The average amount required to produce five to ten minutes of surgical anesthesia has been 2 mg/kg (1 mg/lb).

Alternatively, in adult patients an induction dose of 1 mg to 2 mg/kg intravenous ketamine at a rate of 0.5 mg/kg/min may be used for induction of anesthesia. In addition, diazepam in 2 mg to 5 mg doses, administered in a separate syringe over 60 seconds, may be used. In most cases, 15 mg of intravenous diazepam or less will suffice. The incidence of psychological manifestations during emergence, particularly dream-like observations and emergence delirium, may be reduced by this induction dosage program.

Note: The 100 mg/mL concentration of ketamine hydrochloride should not be injected intravenously without proper dilution. It is recommended the drug be diluted with an equal volume of either Sterile Water for injection, USP, Normal Saline, or 5% Dextrose in Water.

Rate of Administration:

It is recommended that ketamine hydrochloride be administered slowly (over a period of 60 seconds). More rapid administration may result in respiratory depression and enhanced pressor response.

Intramuscular Route:

The initial dose of ketamine hydrochloride administered intramuscularly may range from 6.5 to 13 mg/kg (3 to 6 mg/lb). A dose of 10 mg/kg (5 mg/lb) will usually produce 12 to 25 minutes of surgical anesthesia.

Maintenance of Anesthesia:

The maintenance dose should be adjusted according to the patient's anesthetic needs and whether an additional anesthetic agent is employed.

Increments of one-half to the full induction dose may be repeated as needed for maintenance of anesthesia. However, it should be noted that purposeless and tonic-clonic movements of extremities may occur during the course of anesthesia. These movements do not imply a light plane and are not indicative of the need for additional doses of the anesthetic.

It should be recognized that the larger the total dose of ketamine hydrochloride administered, the longer will be the time to complete recovery.

Adult patients induced with ketamine hydrochloride augmented with intravenous diazepam may be maintained on ketamine hydrochloride given by slow microdrip infusion technique at a dose of 0.1 to 0.5 mg/minute, augmented with diazepam 2 to 5 mg administered intravenously as needed. In many cases 20 mg or less of intravenous diazepam total for combined induction and maintenance will suffice. However, slightly more diazepam may be required depending on the nature and duration of the operation, physical status of the patient, and other factors. The incidence of psychological manifestations during emergence, particularly dream-like observations and emergence delirium, may be reduced by this maintenance dosage program.

Dilution:

To prepare a dilute solution containing 1 mg of ketamine per mL, aseptically transfer 10 mL from a 50 mg per mL vial or 5 mL from a 100 mg per mL vial to 500 mL of 5% Dextrose Injection, USP or Sodium Chloride (0.9%) Injection, USP (Normal Saline) and mix well. The resultant solution will contain 1 mg of ketamine per mL.

The fluid requirements of the patient and duration of anesthesia must be considered when selecting the appropriate dilution of ketamine hydrochloride injection. If fluid restriction is required, ketamine hydrochloride injection can be added to a 250 mL infusion as described above to provide a ketamine hydrochloride concentration of 2 mg/mL.

Ketamine hydrochloride injection 10 mg/mL vials are not recommended for dilution.

Supplementary Agents:

Ketamine hydrochloride is clinically compatible with the commonly used general and local anesthetic agents when an adequate respiratory exchange is maintained.

The regimen of a reduced dose of ketamine hydrochloride supplemented with diazepam can be used to produce balanced anesthesia by combination with other agents such as nitrous oxide and oxygen.
Triostat

Triostat

Adults

Myxedema coma is usually precipitated in the hypothyroid patient of long standing by intercurrent illness or drugs such as sedatives and anesthetics and should be considered a medical emergency. Therapy should be directed at the correction of electrolyte disturbances, possible infection, or other intercurrent illness in addition to the administration of intravenous liothyronine (T3). Simultaneous glucocorticosteroids are required.

Triostat (liothyronine sodium injection) (T3) is for intravenous administration only. It should not be given intramuscularly or subcutaneously.

Prompt administration of an adequate dose of intravenous liothyronine (T3) is important in determining clinical outcome.

Initial and subsequent doses of Triostat should be based on continuous monitoring of the patient's clinical status and response to therapy.

Triostat doses should normally be administered at least four hours–and not more than 12 hours–apart.

Administration of at least 65 mcg/day of intravenous liothyronine (T3) in the initial days of therapy was associated with lower mortality.

There is limited clinical experience with intravenous liothyronine (T3) at total daily doses exceeding 100 mcg/day.

No controlled clinical studies have been done with Triostat. The following dosing guidelines have been derived from data analysis of myxedema coma/precoma case reports collected by SmithKline Beecham Pharmaceuticals since 1963 and from scientific literature since 1956.

An initial intravenous Triostat dose ranging from 25 mcg to 50 mcg is recommended in the emergency treatment of myxedema coma/precoma in adults. In patients with known or suspected cardiovascular disease, an initial dose of 10 mcg to 20 mcg is suggested (see WARNINGS). However, both the initial dose and subsequent doses should be determined on the basis of continuous monitoring of the patient's clinical condition and response to Triostat therapy. Normally at least four hours should be allowed between doses to adequately assess therapeutic response and no more than 12 hours should elapse between doses to avoid fluctuations in hormone levels. Caution should be exercised in adjusting the dose due to the potential of large changes to precipitate adverse cardiovascular events. Review of the myxedema case reports indicates decreased mortality in patients receiving at least 65 mcg/day in the initial days of treatment. However, there is limited clinical experience at total daily doses above 100 mcg. See PRECAUTIONS–Drug Interactions for potential interactions between thyroid hormones and digitalis and vasopressors.

Pediatric Use

There is limited experience with Triostat in the pediatric population. Safety and effectiveness in pediatric patients have not been established.

Switching to Oral Therapy

Oral therapy should be resumed as soon as the clinical situation has been stabilized and the patient is able to take oral medication. When switching a patient to liothyronine sodium tablets from Triostat, discontinue Triostat, initiate oral therapy at a low dosage, and increase gradually according to the patient's response.

If L-thyroxine rather than liothyronine sodium is used in initiating oral therapy, the physician should bear in mind that there is a delay of several days in the onset of L-thyroxine activity and that intravenous therapy should be discontinued gradually.
Colistimethate

Colistimethate

Important: Colistimethate for injection is supplied in vials containing colistimethate sodium equivalent to 150 mg colistin base activity per vial.

Reconstitution for Intravenous or Intramuscular Administration:

The 150 mg vial should be reconstituted with 2 mL Sterile Water for Injection, USP. The reconstituted solution provides colistimethate sodium at a concentration equivalent to 75 mg/mL colistin base activity.

During reconstitution swirl gently to avoid frothing.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If these conditions are observed, the product should not be used.

Dosage

Adults and Pediatric Patients—Intravenous or Intramuscular Administration:

The dose of Colistimethate for injection should be 2.5 to 5 mg/kg per day of colistin base in 2 to 4 divided doses for patients with normal renal function, depending on the severity of the infection.

In obese individuals, dosage should be based on ideal body weight.

The daily dose and frequency should be reduced for the patients with renal impairment. Suggested modifications of dosage schedule for patients with renal impairment are presented in Table 1.

Administer the second half of the total daily dose by slow intravenous infusion, starting 1 to 2 hours after the initial dose, over the next 22 to 23 hours. In the presence of impaired renal function, reduce the infusion rate depending on the degree of renal impairment. The choice of intravenous solution and the volume to be employed are dictated by the requirements of fluid and electrolyte management. Any final intravenous infusion solution containing colistimethate sodium should be freshly prepared and used for no longer than 24 hours. INTRAMUSCULAR ADMINISTRATION For Intramuscular Injection, administer by deep intramuscular injection into a large muscle mass (such as the gluteal muscles or lateral part of the thigh). Store reconstituted solution for intramuscular injection in a refrigerator 2° to 8°C (36° to 46°F) or between 20° to 25°C (68° to 77°F) and use within 7 days.
Zoledronic Acid

Zoledronic Acid

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

2.1 Hypercalcemia of Malignancy

The maximum recommended dose of Zoledronic Acid Injection in hypercalcemia of malignancy (albumin-corrected serum calcium greater than or equal to 12 mg/dL [3.0 mmol/L]) is 4 mg. The 4-mg dose must be given as a single-dose intravenous infusion over no less than 15 minutes. Patients who receive Zoledronic Acid Injection should have serum creatinine assessed prior to each treatment.

Dose adjustments of Zoledronic Acid Injection are not necessary in treating patients for hypercalcemia of malignancy presenting with mild-to-moderate renal impairment prior to initiation of therapy (serum creatinine less than 400 μmol/L or less than 4.5 mg/dL).

Patients should be adequately rehydrated prior to administration of Zoledronic Acid Injection [see Warnings and Precautions (5.2)].

Consideration should be given to the severity of, as well as the symptoms of, tumor-induced hypercalcemia when considering use of Zoledronic Acid Injection. Vigorous saline hydration, an integral part of hypercalcemia therapy, should be initiated promptly and an attempt should be made to restore the urine output to about 2 L/day throughout treatment. Mild or asymptomatic hypercalcemia may be treated with conservative measures (i.e., saline hydration, with or without loop diuretics). Patients should be hydrated adequately throughout the treatment, but overhydration, especially in those patients who have cardiac failure, must be avoided. Diuretic therapy should not be employed prior to correction of hypovolemia.

Retreatment with Zoledronic Acid Injection 4 mg may be considered if serum calcium does not return to normal or remain normal after initial treatment. It is recommended that a minimum of 7 days elapse before retreatment, to allow for full response to the initial dose. Renal function must be carefully monitored in all patients receiving Zoledronic Acid Injection and serum creatinine must be assessed prior to retreatment with Zoledronic Acid Injection [see Warnings and Precautions (5.2)].

2.2 Multiple Myeloma and Metastatic Bone Lesions of Solid Tumors

The recommended dose of Zoledronic Acid Injection in patients with multiple myeloma and metastatic bone lesions from solid tumors for patients with creatinine clearance greater than 60 mL/min is 4 mg infused over no less than 15 minutes every 3-4 weeks. The optimal duration of therapy is not known.

Upon treatment initiation, the recommended Zoledronic Acid Injection doses for patients with reduced renal function (mild and moderate renal impairment) are listed in Table 1. These doses are calculated to achieve the same AUC as that achieved in patients with creatinine clearance of 75 mL/min. Creatinine clearance (CrCl) is calculated using the Cockcroft-Gault formula [see Warnings and Precautions (5.2)].
Table 1: Reduced Doses for Patients with Baseline CrCl less than or equal to 60 mL/min Baseline Creatinine Clearance (mL/min) Zoledronic Acid Injection Recommended Dose*
*Doses calculated assuming target AUC of 0.66(mg•hr/L) (CrCl = 75mL/min)
greater than 60 4 mg 50 – 60 3.5 mg 40 – 49 3.3 mg 30 – 39 3 mg
During treatment, serum creatinine should be measured before each Zoledronic Acid Injection dose and treatment should be withheld for renal deterioration. In the clinical studies, renal deterioration was defined as follows:
For patients with normal baseline creatinine, increase of 0.5 mg/dL For patients with abnormal baseline creatinine, increase of 1.0 mg/dL
In the clinical studies, Zoledronic Acid Injection treatment was resumed only when the creatinine returned to within 10% of the baseline value. Zoledronic Acid Injection should be reinitiated at the same dose as that prior to treatment interruption.

Patients should also be administered an oral calcium supplement of 500 mg and a multiple vitamin containing 400 IU of Vitamin D daily.

2.3 Preparation of Solution

Zoledronic Acid Injection must not be mixed with calcium or other divalent cation-containing infusion solutions, such as Lactated Ringer's solution, and should be administered as a single intravenous solution in a line separate from all other drugs.

4 mg/5 mL Single-Use Vial

Vials of Zoledronic Acid Injection concentrate for infusion contain overfill allowing for the withdrawal of 5 mL of concentrate (equivalent to 4 mg zoledronic acid). This concentrate should immediately be diluted in 100 mL of sterile 0.9% Sodium Chloride, USP, or 5% Dextrose Injection, USP, following proper aseptic technique, and administered to the patient by infusion. Do not store undiluted concentrate in a syringe, to avoid inadvertent injection.

To prepare reduced doses for patients with baseline CrCl less than or equal to 60 mL/min, withdraw the specified volume of the Zoledronic Acid Injection concentrate from the vial for the dose required (see Table 2).
Table 2: Preparation of Reduced Doses – Zoledronic Acid Injection concentrate Remove and Use Zoledronic Acid Injection Volume (mL) Dose (mg) 4.4 3.5 4.1 3.3 3.8 3.0
The withdrawn concentrate must be diluted in 100 mL of sterile 0.9% Sodium Chloride, USP, or 5% Dextrose Injection, USP.

If not used immediately after dilution with infusion media, for microbiological integrity, the solution should be refrigerated at 2°C-8°C (36°F-46°F). The refrigerated solution should then be equilibrated to room temperature prior to administration. The total time between dilution, storage in the refrigerator, and end of administration must not exceed 24 hours.

2.4 Method of Administration

Due to the risk of clinically significant deterioration in renal function, which may progress to renal failure, single doses of Zoledronic Acid Injection should not exceed 4 mg and the duration of infusion should be no less than 15 minutes [see Warnings And Precautions (5.2)]. In the trials and in postmarketing experience, renal deterioration, progression to renal failure and dialysis, have occurred in patients, including those treated with the approved dose of 4 mg infused over 15 minutes. There have been instances of this occurring after the initial Zoledronic Acid Injection dose.
Dantrolene Sodium

Dantrolene Sodium

For Use in Chronic Spasticity

Prior to the administration of dantrolene sodium, consideration should be given to the potential response to treatment. A decrease in spasticity sufficient to allow a daily function not otherwise attainable should be the therapeutic goal of treatment with dantrolene sodium. Refer to INDICATIONS AND USAGE section for description of response to be anticipated.

It is important to establish a therapeutic goal (regain and maintain a specific function such as therapeutic exercise program, utilization of braces, transfer maneuvers, etc.) before beginning dantrolene sodium therapy. Dosage should be increased until the maximum performance compatible with the dysfunction due to underlying disease is achieved. No further increase in dosage is then indicated.

Usual Dosage

It is important that the dosage be titrated and individualized for maximum effect. The lowest dose compatible with optimal response is recommended.

In view of the potential for liver damage in long-term dantrolene sodium use, therapy should be stopped if benefits are not evident within 45 days.

Adults

The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient's response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose.
25 mg once daily for seven days, then 25 mg t.i.d. for seven days 50 mg t.i.d. for seven days 100 mg t.i.d.
Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.)

Pediatric Patients

The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient's response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose.
0.5 mg/kg once daily for seven days, then 0.5 mg/kg t.i.d. for seven days 1 mg/kg t.i.d. for seven days 2 mg/kg t.i.d.
Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.)

For Malignant Hyperthermia

Preoperatively

Administer 4 to 8 mg/kg/day of oral dantrolene sodium in 3 or 4 divided doses for one or two days prior to surgery, with the last dose being given approximately 3 to 4 hours before scheduled surgery with a minimum of water.

This dosage will usually be associated with skeletal muscle weakness and sedation (sleepiness or drowsiness); adjustment can usually be made within the recommended dosage range to avoid incapacitation or excessive gastrointestinal irritation (including nausea and/or vomiting).

Post Crisis Follow-up

Oral dantrolene sodium should also be administered following a malignant hyperthermia crisis, in doses of 4 to 8 mg/kg per day in four divided doses, for a one to three day period to prevent recurrence of the manifestations of malignant hyperthermia.
Pitocin

Pitocin

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

The dosage of oxytocin is determined by the uterine response and must therefore be individualized and initiated at a very low level. The following dosage information is based upon various regimens and indications in general use.

A. Induction or Stimulation of Labor

Intravenous infusion (drip method) is the only acceptable method of parenteral administration of Pitocin for the induction or stimulation of labor. Accurate control of the rate of infusion is essential and is best accomplished by an infusion pump. It is convenient to piggyback the Pitocin infusion on a physiologic electrolyte solution, permitting the Pitocin infusion to be stopped abruptly without interrupting the electrolyte infusion. This is done in the following way.
1. Preparation a. The standard solution for infusion of Pitocin is prepared by adding 1 mL (containing 10 units of oxytocin) to 1000 mL of 0.9% aqueous sodium chloride or Ringer's lactate. The combined solution containing 10 milliunits (mU) of oxytocin/mL is rotated in the infusion bottle for thorough mixing. b. Establish the infusion with a separate bottle of physiologic electrolyte solution not containing Pitocin. c. Attach (piggyback) the Pitocin-containing bottle with the infusion pump to the infusion line as close to the infusion site as possible. 2. Administration The initial dose should be 0.5–1 mU/min (equal to 3–6 mL of the dilute oxytocin solution per hour). At 30–60 minute intervals the dose should be gradually increased in increments of 1–2 mU/min until the desired contraction pattern has been established. Once the desired frequency of contractions has been reached and labor has progressed to 5–6 cm dilation, the dose may be reduced by similar increments. Studies of the concentrations of oxytocin in the maternal plasma during Pitocin infusion have shown that infusion rates up to 6 mU/min give the same oxytocin levels that are found in spontaneous labor. At term, higher infusion rates should be given with great care, and rates exceeding 9–10 mU/min are rarely required. Before term, when the sensitivity of the uterus is lower because of a lower concentration of oxytocin receptors, a higher infusion rate may be required. 3. Monitoring a. Electronically monitor the uterine activity and the fetal heart rate throughout the infusion of Pitocin. Attention should be given to tonus, amplitude and frequency of contractions, and to the fetal heart rate in relation to uterine contractions. If uterine contractions become too powerful, the infusion can be abruptly stopped, and oxytocic stimulation of the uterine musculature will soon wane (see PRECAUTIONS section). b. Discontinue the infusion of Pitocin immediately in the event of uterine hyperactivity and/or fetal distress. Administer oxygen to the mother, who preferably should be put in a lateral position. The condition of mother and fetus should immediately be evaluated by the responsible physician and appropriate steps taken.
B. Control of Postpartum Uterine Bleeding
1. Intravenous infusion (drip method). If the patient has an intravenous infusion running, 10 to 40 units of oxytocin may be added to the bottle, depending on the amount of electrolyte or dextrose solution remaining (maximum 40 units to 1000 mL). Adjust the infusion rate to sustain uterine contraction and control uterine atony. 2. Intramuscular administration. 1 mL (10 units) of Pitocin can be given after the delivery of the placenta.
C. Treatment of Incomplete, Inevitable, or Elective Abortion

Intravenous infusion of 10 units of Pitocin added to 500 mL of a physiologic saline solution or 5% dextrose-in-water solution may help the uterus contract after a suction or sharp curettage for an incomplete, inevitable, or elective abortion.

Subsequent to intra-amniotic injection of hypertonic saline, prostaglandins, urea, etc., for midtrimester elective abortion, the injection-to-abortion time may be shortened by infusion of Pitocin at the rate of 10 to 20 milliunits (20 to 40 drops) per minute. The total dose should not exceed 30 units in a 12-hour period due to the risk of water intoxication.

The pharmacy bulk package is for use in a pharmacy admixture service only in a suitable work area, such as a laminar flow hood. The closure should be penetrated only once utilizing an appropriate sterile transfer device, which allows measured distribution of the contents. The transfer device should be inserted into the Pharmacy Bulk Package using aseptic technique.

Contents should be used as soon as possible following initial closure puncture. Discard any unused portion within 24 hours of first entry. Following closure puncture, container should be maintained under labeled storage conditions between 20° to 25°C (68° to 77°F) under a laminar flow hood until contents are dispensed.
Oxytocin

Oxytocin

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. The dosage of oxytocin is determined by the uterine response and must therefore be individualized and initiated at a very low level. The following dosage information is based upon various regimens and indications in general use.

A. Induction or Stimulation of Labor

Intravenous infusion (drip method) is the only acceptable method of parenteral administration of oxytocin injection for the induction or stimulation of labor. Accurate control of the rate of infusion is essential and is best accomplished by an infusion pump. It is convenient to piggyback the oxytocin infusion on a physiologic electrolyte solution, permitting the oxytocin infusion to be stopped abruptly without interrupting the electrolyte infusion. This is done in the following way.
1. Preparation a. The standard solution for infusion of oxytocin injection is prepared by adding the contents of one 1 mL vial containing 10 units of oxytocin to 1000 mL of 0.9% aqueous sodium chloride or Ringer's lactate. The combined solution containing 10 milliunits (mU) of oxytocin/mL is rotated in the infusion bottle for thorough mixing. b. Establish the infusion with a separate bottle of physiologic electrolyte solution not containing oxytocin. c. Attach (piggyback) the oxytocin-containing bottle with the infusion pump to the infusion line as close to the infusion site as possible. 2. Administration
The initial dose should be 0.5–1 mU/min (equal to 3–6 mL of the dilute oxytocin solution per hour). At 30–60 minute intervals the dose should be gradually increased in increments of 1–2 mU/min until the desired contraction pattern has been established. Once the desired frequency of contractions has been reached and labor has progressed to 5–6 cm dilation, the dose may be reduced by similar increments.

Studies of the concentrations of oxytocin in the maternal plasma during oxytocin infusion have shown that infusion rates up to 6 mU/min give the same oxytocin levels that are found in spontaneous labor. At term, higher infusion rates should be given with great care, and rates exceeding 9–10 mU/min are rarely required. Before term, when the sensitivity of the uterus is lower because of a lower concentration of oxytocin receptors, a higher infusion rate may be required.
3. Monitoring a. Electronically monitor the uterine activity and the fetal heart rate throughout the infusion of oxytocin. Attention should be given to tonus, amplitude and frequency of contractions, and to the fetal heart rate in relation to uterine contractions. If uterine contractions become too powerful, the infusion can be abruptly stopped, and oxytocic stimulation of the uterine musculature will soon wane (see PRECAUTIONS section). b. Discontinue the infusion of oxytocin immediately in the event of uterine hyperactivity and/or fetal distress. Administer oxygen to the mother, who preferably should be put in a lateral position. The condition of mother and fetus should immediately be evaluated by the responsible physician and appropriate steps taken.
B. Control of Postpartum Uterine Bleeding
Intravenous infusion (drip method). If the patient has an intravenous infusion running, 10 to 40 units of oxytocin may be added to the bottle, depending on the amount of electrolyte or dextrose solution remaining (maximum 40 units to 1000 mL). Adjust the infusion rate to sustain uterine contraction and control uterine atony. Intramuscular administration. (One mL) Ten (10) units of oxytocin injection can be given after the delivery of the placenta.
C. Treatment of Incomplete, Inevitable, or Elective Abortion

Intravenous infusion of 10 units of oxytocin injection added to 500 mL of a physiologic saline solution or 5% dextrose-in-water solution may help the uterus contract after a suction or sharp curettage for an incomplete, inevitable, or elective abortion.

Subsequent to intra-amniotic injection of hypertonic saline, prostaglandins, urea, etc., for midtrimester elective abortion, the injection-to-abortion time may be shortened by infusion of oxytocin at the rate of 10 to 20 milliunits (20 to 40 drops) per minute. The total dose should not exceed 30 units in a 12-hour period due to the risk of water intoxication.
Estradiol Valerate

Estradiol Valerate

When estrogen is prescribed for a postmenopausal woman with a uterus, progestin should also be initiated to reduce the risk of endometrial cancer. A woman without a uterus does not need progestin. Use of estrogen, alone or in combination with a progestin, should be with the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Patients should be reevaluated periodically as clinically appropriate (e.g., 3-month to 6-month intervals) to determine if treatment is still necessary (See BOXED WARNINGS and WARNINGS). For women who have a uterus, adequate diagnostic measures, such as endometrial sampling, when indicated, should be undertaken to rule out malignancy in cases of undiagnosed persistent or recurring abnormal vaginal bleeding.

Care should be taken to inject deeply into the upper, outer quadrant of the gluteal muscle following the usual precautions for intramuscular administration. By virtue of the low viscosity of the vehicles, the various preparations of estradiol valerate injection, USP may be administered with a small gauge needle (i.e., 20 Gauge × 1 ½ inches long). Since the 40 mg potency provides a high concentration in a small volume, particular care should be observed to administer the full dose.

Estradiol valerate injection should be visually inspected for particulate matter and color prior to administration; the solution is clear, colorless to pale yellow. Storage at low temperatures may result in the separation of some crystalline material which redissolves readily on warming.

Note: A dry needle and syringe should be used. Use of a wet needle or syringe may cause the solution to become cloudy; however, this does not affect the potency of the material.

Patients should be started at the lowest dose for the indication. The lowest effective dose of estradiol valerate has not been determined for any indication. Treated patients with an intact uterus should be monitored closely for signs of endometrial cancer, and appropriate diagnostic measures should be taken to rule out malignancy in the event of persistent or recurring abnormal vaginal bleeding. See PRECAUTIONS concerning addition of a progestin.
1. For treatment of moderate to severe vasomotor symptoms, vulvar and vaginal atrophy associated with the menopause, the lowest dose and regimen that will control symptoms should be chosen and medication should be discontinued as promptly as possible. The usual dosage is 10 to 20 mg estradiol valerate every four weeks. Attempts to discontinue or taper medication should be made at 3-month to 6-month intervals. 2. For treatment of female hypoestrogenism due to hypogonadism, castration, or primary ovarian failure. The usual dosage is 10 to 20 mg estradiol valerate every four weeks. 3. For treatment of advanced androgen-dependent carcinoma of the prostate, for palliation only. The usual dosage is 30 mg or more administered every one or two weeks.
