Proamatine

Proamatine

The recommended dose of ProAmatine® is 10 mg, 3 times daily. Dosing should take place during the daytime hours when the patient needs to be upright, pursuing the activities of daily living. A suggested dosing schedule of approximately 4-hour intervals is as follows: shortly before, or upon arising in the morning, midday and late afternoon (not later than 6 P.M.). Doses may be given in 3-hour intervals, if required, to control symptoms, but not more frequently. Single doses as high as 20 mg have been given to patients, but severe and persistent systolic supine hypertension occurs at a high rate (about 45%) at this dose. In order to reduce the potential for supine hypertension during sleep, ProAmatine® should not be given after the evening meal or less than 4 hours before bedtime. Total daily doses greater than 30 mg have been tolerated by some patients, but their safety and usefulness have not been studied systematically or established. Because of the risk of supine hypertension, ProAmatine® should be continued only in patients who appear to attain symptomatic improvement during initial treatment.

The supine and standing blood pressure should be monitored regularly, and the administration of ProAmatine® should be stopped if supine blood pressure increases excessively.

Because desglymidodrine is excreted renally, dosing in patients with abnormal renal function should be cautious; although this has not been systematically studied, it is recommended that treatment of these patients be initiated using 2.5-mg doses.

Dosing in children has not been adequately studied.

Blood levels of midodrine and desglymidodrine were similar when comparing levels in patients 65 or older vs. younger than 65 and when comparing males vs. females, suggesting dose modifications for these groups are not necessary.
Firazyr

Firazyr

2.1 Recommended Dosing

The recommended dose of FIRAZYR is 30 mg administered by subcutaneous (SC) injection in the abdominal area. Additional doses may be administered at intervals of at least 6 hours if response is inadequate or if symptoms recur. No more than 3 doses may be administered in any 24 hour period.

2.2 Administration Instructions

FIRAZYR should be inspected visually for particulate matter and discoloration prior to administration. The drug solution should be clear and colorless. Do not administer if the product contains particulates or is discolored.

Attach the provided 25 gauge needle to the syringe hub and screw on securely. Do not use a different needle. Disinfect the injection site and administer FIRAZYR by subcutaneous injection over at least 30 seconds.

Patients may self-administer FIRAZYR upon recognition of symptoms of an HAE attack after training under the guidance of a healthcare professional [see Patient Counseling Information (17)].
Elaprase

Elaprase

2.1 Recommended Dose

The recommended dosage regimen of ELAPRASE is 0.5 mg per kg of body weight administered once weekly as an intravenous infusion.

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

2.2 Preparation Instructions

Prepare and use ELAPRASE according to the following steps using aseptic technique:
Determine the total volume of ELAPRASE to be administered and the number of vials needed based on the patient's weight and the recommended dose of 0.5 mg/kg. Patient's weight (kg) × 0.5 mg per kg of ELAPRASE ÷ 2 mg per mL = Total mL of ELAPRASE Total mL of ELAPRASE ÷ 3 mL per vial = Total number of vials Round up to the next whole vial to determine the total number of vials needed. Remove the required number of vials from the refrigerator to allow them to reach room temperature. Before withdrawing the ELAPRASE solution from the vial, visually inspect each vial for particulate matter and discoloration. The ELAPRASE solution should be clear to slightly opalescent and colorless. Do not use if the solution is discolored or if there is particulate matter in the solution. Do not shake the ELAPRASE solution. Withdraw the calculated volume of ELAPRASE from the appropriate number of vials. Add the calculated volume of ELAPRASE solution to a 100 mL bag of 0.9% Sodium Chloride Injection, USP for intravenous infusion. Mix gently. Do not shake the solution.
2.3 Administration Instructions

Administer the diluted ELAPRASE solution to patients using a low-protein-binding infusion set equipped with a low-protein-binding 0.2 micrometer (µm) in-line filter.

The total volume of infusion should be administered over a period of 3 hours, which may be gradually reduced to 1 hour if no hypersensitivity reactions are observed. Patients may require longer infusion times if hypersensitivity reactions occur; however, infusion times should not exceed 8 hours. The initial infusion rate should be 8 mL per hour for the first 15 minutes. If the infusion is well tolerated, the rate of infusion may be increased by 8 mL per hour increments every 15 minutes. The infusion rate should not exceed 100 mL per hour. The infusion rate may be slowed, temporarily stopped, or discontinued for that visit in the event of hypersensitivity reactions [see Warnings and Precautions (5.1)]. ELAPRASE should not be infused with other products in the infusion tubing.

2.4 Storage and Stability

ELAPRASE does not contain preservatives; therefore, after dilution with saline, the infusion bags should be used immediately. If immediate use is not possible, the diluted solution should be stored refrigerated at 2°C to 8°C (36°F to 46 °F) for up to 24 hours. Other than during infusion, do not store the diluted ELAPRASE solution at room temperature. Any unused product or waste material should be discarded and disposed of in accordance with local requirements.
Intuniv

Intuniv

2.1 General Instruction for Use

Swallow tablets whole. Do not crush, chew, or break tablets because this will increase the rate of guanfacine release. Do not administer with high fat meals, due to increased exposure.

2.2 Dose Selection

Take INTUNIV orally once daily, either in the morning or evening, at approximately the same time each day. Begin at a dose of 1 mg/day, and adjust in increments of no more than 1 mg/week.

In monotherapy clinical trials, there was dose- and exposure-related clinical improvement as well as risks for several clinically significant adverse reactions (hypotension, bradycardia, sedative events). To balance the exposure-related potential benefits and risks, the recommended target dose range depending on clinical response and tolerability for INTUNIV® is 0.05-0.12 mg/kg/day (total daily dose between 1-7 mg) (See Table 1).
Table 1: Recommended Target Dose Range for Therapy with INTUNIV® Weight Target dose range (0.05 - 0.12 mg/kg/day) Doses above 4 mg/day have not been evaluated in children (ages 6-12 years) and doses above 7 mg/day have not been evaluated in adolescents (ages 13-17 years) 25-33.9 kg 2-3 mg/day 34-41.4 kg 2-4 mg/day 41.5-49.4 kg 3-5 mg/day 49.5-58.4 kg 3-6 mg/day 58.5-91 kg 4-7 mg/day >91 kg 5-7 mg/day
In the adjunctive trial which evaluated INTUNIV® treatment with psychostimulants, the majority of patients reached optimal doses in the 0.05-0.12 mg/kg/day range. Doses above 4 mg/day have not been studied in adjunctive trials.

2.3 Switching from Immediate-Release Guanfacine to INTUNIV®

If switching from immediate-release guanfacine, discontinue that treatment, and titrate with INTUNIV® following above recommended schedule.

Do not substitute for immediate-release guanfacine tablets on a milligram-per-milligram basis, because of differing pharmacokinetic profiles. INTUNIV® has significantly reduced Cmax (60% lower), bioavailability (43% lower), and a delayed Tmax (3 hours later) compared to those of the same dose of immediate-release guanfacine [see Clinical Pharmacology (12.3)].

2.4 Maintenance Treatment

Pharmacological treatment of ADHD may be needed for extended periods. Healthcare providers should periodically re-evaluate the long-term use of INTUNIV®, and adjust weight-based dosage as needed. The majority of children and adolescents reach optimal doses in the 0.05-0.12 mg/kg/day range. Doses above 4 mg/day have not been evaluated in children (ages 6-12 years) and above 7 mg/day have not been evaluated in adolescents (ages 13-17 years) [see Clinical Studies (14)].

2.5 Discontinuation of Treatment

Following discontinuation of INTUNIV®, patients may experience increases in blood pressure and heart rate [see Adverse Reaction (6.1)]. Patients/caregivers should be instructed not to discontinue INTUNIV® without consulting their health care provider. Monitor blood pressure and pulse when reducing the dose or discontinuing the drug. Taper the daily dose in decrements of no more than 1 mg every 3 to 7 days to avoid rebound hypertension.

2.6 Missed Doses

When reinitiating patients to the previous maintenance dose after two or more missed consecutive doses, consider titration based on patient tolerability.

2.7 Dosage Adjustment with Concomitant Use of Strong CYP3A4 Inhibitors or Inducers

Dosage adjustments for INTUNIV® are recommended with concomitant use of strong CYP3A4 inhibitors (e.g., ketoconazole), or CYP3A4 inducers (e.g., carbamazepine) (Table 2) [see Drug Interactions (7)].
Table 2: INTUNIV® Dosage Adjustments for Patients Taking Concomitant CYP3A4 Inhibitors or Inducers Clinical Scenarios Starting INTUNIV® while currently on a CYP3A4 modulator Continuing INTUNIV® while adding a CYP3A4 modulator Continuing INTUNIV® while stopping a CYP3A4 modulator CYP3A4 Strong Inhibitors Decrease INTUNIV® dosage to half the recommended level.(see Table 1) Decrease INTUNIV® dosage to half the recommended level.(see Table 1) Increase INTUNIV® dosage to recommended level.(see Table 1) CYP3A4 Strong Inducers Consider increasing INTUNIV® dosage up to double the recommended level.(see Table 1) Consider increasing INTUNIV® dosage up to double the recommended level over 1 to 2 weeks.(see Table 1) Decrease INTUNIV® dosage to recommended level over 1 to 2 weeks.(see Table 1)
Carbatrol

Carbatrol

Monitoring of blood levels has increased the efficacy and safety of anticonvulsants (see PRECAUTIONS, Laboratory Tests). Dosage should be adjusted to the needs of the individual patients. A low initial daily dosage with gradual increase is advised. As soon as adequate control is achieved, the dosage may be reduced very gradually to the minimum effective level. Carbatrol® may be taken with or without food. Carbatrol® capsules may be swallowed whole or may be opened and all the beads sprinkled on a teaspoon of soft food such as applesauce. Make sure all of the food and medicine mixture is swallowed. Do not crush or chew Carbatrol® capsules or the sprinkled beads.

Carbatrol® is an extended-release formulation for twice a day administration. When converting patients from immediate release carbamazepine to Carbatrol® extended-release capsules, the same total daily mg dose of carbamazepine should be administered. Following conversion to Carbatrol®, patients should be closely monitored for seizure control. Depending on the therapeutic response after conversion, the total daily dose may need to be adjusted within the recommended dosing instructions.

Epilepsy (see INDICATIONS AND USAGE)

Adults and children over 12 years of age. Initial: 200 mg twice daily. Increase at weekly intervals by adding up to 200 mg/day until the optimal response is obtained. Dosage generally should not exceed 1000 mg per day in children 12-15 years of age, and 1200 mg daily in patients above 15 years of age. Doses up to 1600 mg daily have been used in adults. Maintenance: Adjust dosage to the minimum effective level, usually 800-1200 mg daily.

Children under 12 years of age: Children taking total daily dosages of immediate-release carbamazepine of 400 mg or greater may be converted to the same total daily dosage of Carbatrol® extended-release capsules, using a twice daily regimen. Ordinarily, optimal clinical response is achieved at daily doses below 35 mg/kg. If satisfactory clinical response has not been achieved, plasma levels should be measured to determine whether or not they are in the therapeutic range. No recommendation regarding the safety of Carbatrol® for use at doses above 35 mg/kg/24 hours can be made.

Combination Therapy: Carbatrol® may be used alone or with other anticonvulsants. When added to existing anticonvulsant therapy, the drug should be added gradually while the other anticonvulsants are maintained or gradually decreased, except phenytoin, which may have to be increased (see PRECAUTIONS, Drug Interactions, and Pregnancy Category D).

Trigeminal Neuralgia (see INDICATIONS AND USAGE)

Initial: On the first day, start with one 200 mg capsule. This daily dose may be increased by up to 200 mg/day every 12 hours only as needed to achieve freedom from pain. Do not exceed 1200 mg daily.

Maintenance: Control of pain can be maintained in most patients with 400-800 mg daily. However, some patients may be maintained on as little as 200 mg daily, while others may require as much as 1200 mg daily. At least once every 3 months throughout the treatment period, attempts should be made to reduce the dose to the minimum effective level or even to discontinue the drug.
Adderall Xr

Adderall Xr

2.1 Dosing Considerations for all Patients

Individualize the dosage according to the therapeutic needs and response of the patient. Administer ADDERALL XR at the lowest effective dosage.

Based on bioequivalence data, patients taking divided doses of immediate-release ADDERALL, (for example, twice daily), may be switched to ADDERALL XR at the same total daily dose taken once daily. Titrate at weekly intervals to appropriate efficacy and tolerability as indicated.

ADDERALL XR capsules may be taken whole, or the capsule may be opened and the entire contents sprinkled on applesauce. If the patient is using the sprinkle administration method, the sprinkled applesauce should be consumed immediately; it should not be stored. Patients should take the applesauce with sprinkled beads in its entirety without chewing. The dose of a single capsule should not be divided. The contents of the entire capsule should be taken, and patients should not take anything less than one capsule per day.

ADDERALL XR may be taken with or without food.

ADDERALL XR should be given upon awakening. Afternoon doses should be avoided because of the potential for insomnia.

Where possible, ADDERALL XR therapy should be interrupted occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued therapy.

2.2 Children

In children with ADHD who are 6-12 years of age and are either starting treatment for the first time or switching from another medication, start with 10 mg once daily in the morning; daily dosage may be adjusted in increments of 5 mg or 10 mg at weekly intervals. When in the judgment of the clinician a lower initial dose is appropriate, patients may begin treatment with 5 mg once daily in the morning. The maximum recommended dose for children is 30 mg/day; doses greater than 30 mg/day of ADDERALL XR have not been studied in children. ADDERALL XR has not been studied in children under 6 years of age.

2.3 Adolescents

The recommended starting dose for adolescents with ADHD who are 13-17 years of age and are either starting treatment for the first time or switching from another medication is 10 mg/day. The dose may be increased to 20 mg/day after one week if ADHD symptoms are not adequately controlled.

2.4 Adults

In adults with ADHD who are either starting treatment for the first time or switching from another medication, the recommended dose is 20 mg/day.
Agrylin

Agrylin

2.1 Starting Dose

Adults: The recommended starting dosage of AGRYLIN is 0.5 mg four times daily or 1 mg twice daily.

Pediatric Patients: The recommended starting dosage of AGRYLIN is 0.5 mg daily.

2.2 Titration

Continue the starting dose for at least one week and then titrate to reduce and maintain the platelet count below 600,000/µL, and ideally between 150,000/µL and 400,000/µL. The dose increment should not exceed 0.5 mg/day in any one week. Dosage should not exceed 10 mg/day or 2.5 mg in a single dose [see Warnings and Precautions (5)]. Most patients will experience an adequate response at a dose of 1.5 to 3.0 mg/day. Monitor platelet counts weekly during titration then monthly or as necessary.

2.3 Dose Modifications for Hepatic Impairment

In patients with moderate hepatic impairment (Child Pugh score 7-9) start AGRYLIN therapy at a dose of 0.5 mg/day and monitor frequently for cardiovascular events [see Warnings and Precautions (5.1), Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)]. Patients with moderate hepatic impairment who have tolerated AGRYLIN therapy for one week may have their dose increased. The dose increase increment should not exceed 0.5 mg/day in any one week. Avoid use of AGRYLIN in patients with severe hepatic impairment.

2.4 Clinical Monitoring

AGRYLIN therapy requires clinical monitoring, including complete blood counts, assessment of hepatic and renal function, and electrolytes.

To prevent the occurrence of thrombocytopenia, monitor platelet counts every two days during the first week of treatment and at least weekly thereafter until the maintenance dosage is reached. Typically, platelet counts begin to respond within 7 to 14 days at the proper dosage. In the clinical trials, the time to complete response, defined as platelet count ≤ 600,000/µL, ranged from 4 to 12 weeks. In the event of dosage interruption or treatment withdrawal, the rebound in platelet count is variable, but platelet counts typically will start to rise within 4 days and return to baseline levels in one to two weeks, possibly rebounding above baseline values. Monitor platelet counts frequently.
Atorvastatin Calcium

Atorvastatin Calcium

2.1 Recommended Starting Dosage in Patients Naïve to Enzyme Replacement Therapy

VPRIV should be administered under the supervision of a healthcare professional. The recommended starting VPRIV dosage in naïve adults and naïve pediatric patients 4 years of age and older is 60 Units/kg administered every other week as a 60-minute intravenous infusion. The dosage can be adjusted based on achievement and maintenance of each patient's therapeutic goals.

2.2 Switching from Imiglucerase to VPRIV

Adults and pediatric patients 4 years of age and older currently being treated on a stable dosage of imiglucerase for type 1 Gaucher disease may be switched to VPRIV by starting treatment with VPRIV at the previous imiglucerase dosage two weeks after the last imiglucerase dose. VPRIV should be administered under the supervision of a healthcare professional as a 60-minute intravenous infusion. The dosage can be adjusted based on achievement and maintenance of each patient's therapeutic goals.

2.3 Reconstitution of the VPRIV Lyophilized Powder

VPRIV is a lyophilized powder, which requires reconstitution and dilution, using sterile technique, prior to intravenous infusion. VPRIV should be prepared as follows:
(a) Determine the number of vials to be reconstituted based on the individual patient's weight and the prescribed dose. (b) Inject 4.3 mL of Sterile Water for Injection, USP into a vial containing VPRIV lyophilized powder. (c) Mix gently. DO NOT SHAKE. The reconstituted VPRIV solution will have a 100 Units/mL concentration (400 Units VPRIV in 4 mL of solution). (d) If additional vials are needed, repeat steps (b) and (c) (e) Visually inspect the reconstituted VPRIV solution in the vials. The solution should be clear to slightly opalescent and colorless. Do not use if the solution is discolored or if foreign particulate matter is present. (f) With a single syringe, withdraw the calculated dose of drug from the appropriate number of vials. Using a separate syringe, withdraw air from a bag of 100 mL of 0.9% sodium chloride solution suitable for intravenous administration. Then dilute the calculated dose of VPRIV directly into the sodium chloride solution. Mix gently. DO NOT SHAKE. Slight flocculation (described as white irregular shaped particles) may occasionally occur. Diluted solution with slight flocculation is acceptable for administration. (g) Because VPRIV contains no preservatives, use the reconstituted VPRIV solution and the diluted VPRIV solution immediately. If immediate use is not possible, the reconstituted VPRIV solution or the diluted VPRIV solution may be stored for up to 24 hours at 2 °C to 8°C (36 °F to 46°F). Do not freeze and protect from light. Complete the infusion within 24 hours of reconstitution of vials. (h) Vials are for single use only. Discard any unused solution.
2.4 Important Administration Instructions

Administer the diluted VPRIV solution through an in-line low protein-binding 0.2μm filter over 60 minutes. Do not infuse VPRIV with other products in the same infusion tubing because the compatibility of a VPRIV solution with other products has not been evaluated.

2.5 Premedication to Reduce Risk of Subsequent Hypersensitivity Reactions

Consider pre-treatment with antihistamines and/or corticosteroids in patients who exhibited symptoms of hypersensitivity associated with prior VPRIV infusions. Appropriate medical support should be readily available when VPRIV is administered [see Warnings and Precautions (5.1)].
Lialda

Lialda

The recommended dosage for the induction of remission in adult patients with active, mild to moderate ulcerative colitis is two to four 1.2 g tablets taken once daily with a meal for a total daily dose of 2.4 g or 4.8 g. The recommended dosage for the maintenance of remission is two 1.2 g tablets taken once daily with a meal for a total daily dose of 2.4 g.
Pentasa

Pentasa

The recommended dosage for the induction of remission and the symptomatic treatment of mildly to moderately active ulcerative colitis is 1g (4 PENTASA 250 mg capsules or 2 PENTASA 500 mg capsules) 4 times a day for a total daily dosage of 4g. Treatment duration in controlled trials was up to 8 weeks.

PENTASA capsules may be swallowed whole, or alternatively, the capsule may be opened and the entire contents sprinkled onto applesauce or yogurt. The entire contents should be consumed immediately. The capsules and capsule contents must not be crushed or chewed.

Safety and efficacy of PENTASA in pediatric patients have not been established.
Fosrenol

Fosrenol

Divide the total daily dose of FOSRENOL and take with or immediately after meals. The recommended initial total daily dose of FOSRENOL is 1500 mg. Titrate the dose every 2-3 weeks until an acceptable serum phosphate level is reached. Monitor serum phosphate levels as needed during dose titration and on a regular basis thereafter.

In clinical studies of ESRD patients, FOSRENOL doses up to 4500 mg were evaluated. Most patients required a total daily dose between 1500 mg and 3000 mg to reduce plasma phosphate levels to less than 6.0 mg/dL. Doses were generally titrated in increments of 750 mg/day.

Information for FOSRENOL Chewable Tablets

Chew or crush FOSRENOL Chewable Tablets completely before swallowing. Do not swallow intact FOSRENOL Chewable Tablets.

Information for FOSRENOL Oral Powder

Sprinkle FOSRENOL Oral Powder on a small quantity of applesauce or other similar food and consume immediately. Do not open until ready to use. Do not store FOSRENOL Oral Powder for future use once mixed with food. As FOSRENOL Oral Powder is insoluble, do not attempt to dissolve in liquid for administration.

Consider using the oral powder formulation in patients with poor dentition.
