Adjust dosage to individual and the severity of his condition, recognizing that the milligram for milligram potency relationship among all dosage forms has not been precisely established clinically. It is important to increase dosage until symptoms are controlled. Dosage should be increased more gradually in debilitated or emaciated patients. In continued therapy, gradually reduce dosage to the lowest effective maintenance level, after symptoms have been controlled for a reasonable period.

Increase parenteral dosage only if hypotension has not occurred. Before using IM, see . Important Notes On Injection

ELDERLY PATIENTS

In general, dosages in the lower range are sufficient for most elderly patients. Since they appear to be more susceptible to hypotension and neuromuscular reactions, such patients should be observed closely. Dosage should be tailored to the individual, response carefully monitored, and dosage adjusted accordingly. Dosage should be increased more gradually in elderly patients.

PSYCHOTIC DISORDERS

Increase dosage gradually until symptoms are controlled. Maximum improvement may not be seen for weeks or even months. Continue optimum dosage for 2 weeks; then gradually reduce dosage to the lowest effective maintenance level. Daily dosage of 200 mg is not unusual. Some patients require higher dosages (e.g., 800 mg daily is not uncommon in discharged mental patients).

Hospitalized Patients: Acute Schizophrenic or Manic States

25 mg (1 mL). If necessary, give additional 25 to 50 mg injection in 1 hour.

DOSAGE AND ADMINISTRATION–ADULTS

Adjust dosage to individual and the severity of his condition, recognizing that the milligram for milligram potency relationship among all dosage forms has not been precisely established clinically. It is important to increase dosage until symptoms are controlled. Dosage should be increased more gradually in debilitated or emaciated patients. In continued therapy, gradually reduce dosage to the lowest effective maintenance level, after symptoms have been controlled for a reasonable period.

The 100 mg and 200 mg tablets are for use in severe neuropsychiatric conditions.

Elderly Patients – In general, dosages in the lower range are sufficient for most elderly patients. Since they appear to be more susceptible to hypotension and neuromuscular reactions, such patients should be observed closely. Dosage should be tailored to the individual, response carefully monitored, and dosage adjusted accordingly. Dosage should be increased more gradually in elderly patients.

Continue optimum dosage for 2 weeks; then gradually reduce dosage to the lowest effective maintenance level. Daily dosage of 200 mg is not unusual. Some patients require higher dosages (e.g., 800 mg daily is not uncommon in discharged mental patients).

Hospitalized Patients:
Acute Schizophrenic or Manic States – It is recommended that initial treatment be with chlorpromazine HCI injection until patient is controlled. Usually patient becomes quiet and co-operative within 24 to 48 hours and oral doses may be substituted and increased until the patient is calm. 500 mg a day is generally sufficient. While gradual increases to 2,000 mg a day or more may be necessary, there is usually little therapeutic gain to be achieved by exceeding 1,000 mg a day for extended periods. In general, dosage levels should be lower in the elderly, the emaciated and the debilitated.

Less Acutely Disturbed – 25 mg t.i.d. Increase gradually until effective dose is reached – usually 400 mg daily.

Outpatients – 10 mg t.i.d. or q.i.d., or 25 mg b.i.d. or t.i.d.

More Severe Cases – 25 mg t.i.d. After 1 or 2 days, daily dosage may be increased by 20 to 50 mg at semiweekly intervals until patient becomes calm and cooperative.

Prompt Control of Severe Symptoms – Initial treatment should be with intransmuscular chlorpromazine. Subsequent doses should be oral, 25-50 mg t.i.d.

Nausea and Vomiting– 10 to 25 mg q4 to 6h, p.r.n., increased, if necessary.

Presurgical Apprehension– 25 to 50 mg, 2 to 3 hours before the operation.

Intractable Hiccups– 25 to 50 mg t.i.d. or q.i.d. If symptoms persist for 2-3 days, parenteral therapy is indicated.

Acute Intermittent Porphyria– 25 to 50 mg t.i.d. or q.i.d. Can usually be discontinued after several weeks, but maintenance therapy may be necessary for some patients.

DOSAGE AND ADMINISTRATION – PEDIATRIC PATIENTS (6 months to 12 years of age)

Presurgical Apprehension

1/4 mg/lb body weight orally 2 to 3 hours before operation.

2.1 Hypertension

The recommended initial dose for patients not receiving a diuretic is 2.5 mg once a day. Adjust dose according to blood pressure response. The usual maintenance dosage range is 2.5 mg to 20 mg per day administered as a single dose or in two equally divided doses. In some patients treated once daily, the antihypertensive effect may diminish toward the end of the dosing interval. In such patients, consider an increase in dosage or twice daily administration. If blood pressure is not controlled with ramipril capsules alone, a diuretic can be added.

2.3 Heart Failure Post-Myocardial Infarction

For the treatment of post-myocardial infarction patients who have shown signs of congestive heart failure, the recommended starting dose of ramipril capsules is 2.5 mg twice daily (5 mg per day). A patient who becomes hypotensive at this dose may be switched to 1.25 mg twice daily. After one week at the starting dose, increase dose (if tolerated) toward a target dose of 5 mg twice daily, with dosage increases being about 3 weeks apart.

After the initial dose of ramipril capsules, observe the patient under medical supervision for at least two hours and until blood pressure has stabilized for at least an additional hour If possible, reduce the dose of any concomitant diuretic as this may diminish the likelihood of hypotension. The appearance of hypotension after the initial dose of ramipril capsules does not preclude subsequent careful dose titration with the drug, following effective management of the hypotension [ ]. .see Warnings and Precautions ( ), Drug Interactions ( ) 5.57.1

2.4 General Dosing Information

Generally, swallow ramipril capsules whole. The ramipril capsule can also be opened and the contents sprinkled on a small amount (about 4 oz.) of applesauce or mixed in 4 oz. (120 mL) of water or apple juice. To be sure that ramipril is not lost when such a mixture is used, consume the mixture in its entirety. The described mixtures can be pre-prepared and stored for up to 24 hours at room temperature or up to 48 hours under refrigeration.

Concomitant administration of ramipril capsules with potassium supplements, potassium salt substitutes, or potassium-sparing diuretics can lead to increases of serum potassium [ ]. see Warnings and Precautions ( ) 5.8

2.5 Dosage Adjustment

Renal Impairment

Establish baseline renal function in patients initiating ramipril capsules. Usual regimens of therapy with ramipril capsules may be followed in patients with estimated creatinine clearance > 40 mL/min. However, in patients with worse impairment, 25% of the usual dose of ramipril is expected to produce full therapeutic levels of ramiprilat [ ]. see Use in Specific Populations ( ) 8.6

Hypertension

For patients with hypertension and renal impairment, the recommended initial dose is 1.25 mg ramipril capsules once daily. Dosage may be titrated upward until blood pressure is controlled or to a maximum total daily dose of 5 mg.

Heart Failure Post-Myocardial Infarction

For patients with heart failure and renal impairment, the recommended initial dose is 1.25 mg ramipril capsules once daily. The dose may be increased to 1.25 mg twice daily, and up to a maximum dose of 2.5 mg twice daily depending on clinical response and tolerability.

Volume Depletion or Renal Artery Stenosis

Blood pressure decreases associated with any dose of ramipril capsules depend, in part, on the presence or absence of volume depletion (e.g., past and current diuretic use) or the presence or absence of renal artery stenosis. If such circumstances are suspected to be present, initiate dosing at 1.25 mg once daily. Adjust dosage according to blood pressure response.

Dosage should be tailored to the individual, response carefully monitored, and dosage adjusted accordingly. Dosage should be increased more gradually in elderly patients.

Psychotic Disorders – Increase dosage gradually until symptoms are controlled. Maximum improvement may not be seen for weeks or even months. Continue optimum dosage for 2 weeks; then gradually reduce dosage to the lowest effective maintenance level. Daily dosage of 200 mg is not unusual. Some patients require higher dosages (e.g., 800 mg daily is not uncommon in discharged mental patients).

Hospitalized Patients:
Acute Schizophrenic or Manic States – It is recommended that initial treatment be with chlorpromazine HCI injection until patient is controlled. Usually patient becomes quiet and co-operative within 24 to 48 hours and oral doses may be substituted and increased until the patient is calm. 500 mg a day is generally sufficient. While gradual increases to 2,000 mg a day or more may be necessary, there is usually little therapeutic gain to be achieved by exceeding 1,000 mg a day for extended periods. In general, dosage levels should be lower in the elderly, the emaciated and the debilitated.

Less Acutely Disturbed – 25 mg t.i.d. Increase gradually until effective dose is reached – usually 400 mg daily.

Outpatients – 10 mg t.i.d. or q.i.d., or 25 mg b.i.d. or t.i.d.

More Severe Cases – 25 mg t.i.d. After 1 or 2 days, daily dosage may be increased by 20 to 50 mg at semiweekly intervals until patient becomes calm and cooperative.

Prompt Control of Severe Symptoms – Initial treatment should be with intransmuscular chlorpromazine. Subsequent doses should be oral, 25-50 mg t.i.d.

Nausea and Vomiting– 10 to 25 mg q4 to 6h, p.r.n., increased, if necessary.

Presurgical Apprehension– 25 to 50 mg, 2 to 3 hours before the operation.

Intractable Hiccups– 25 to 50 mg t.i.d. or q.i.d. If symptoms persist for 2-3 days, parenteral therapy is indicated.

Acute Intermittent Porphyria– 25 to 50 mg t.i.d. or q.i.d. Can usually be discontinued after several weeks, but maintenance therapy may be necessary for some patients.

DOSAGE AND ADMINISTRATION – PEDIATRIC PATIENTS (6 months to 12 years of age)

Chlorpromazine should generally not be used in pediatric patients under 6 months of age except where potentially lifesaving. It should not be used in conditions for which specific pediatric dosages have not been established.

Severe Behavioral Problems

Outpatients – Select route of administration according to severity of patient's condition and increase dosage gradually as required. Oral: ¼ mg/lb body weight q4 to 6h, p.r.n. (e.g., for 40 lb child – 10 mg q4 to 6h).

Hospitalized Patients – As with outpatients, start with low doses and increase dosage gradually. In severe behavior disorders, higher dosages (50-100 mg daily and in older children, 200 mg daily or more) may be necessary. There is little evidence that behavior improvement in severely disturbed mentally retarded patients is further enhanced by doses beyond 500 mg per day.

Nausea and Vomiting– Dosage and frequency of administration should be adjusted according to the severity of the symptoms and response of the patient. The duration of activity following intramuscular administration may last up to 12 hours. Subsequent doses may be given by the same route if necessary. Oral: ¼ mg/lb body weight (e.g., 40 lb child – 10 mg q4 to 6h).

Presurgical Apprehension–¼ mg/lb body weight orally 2 to 3 hours before operation.

DOSAGE AND ADMINISTRATION–ADULTS

Adjust dosage to individual and the severity of his condition, recognizing that the milligram for milligram potency relationship among all dosage forms has not been precisely established clinically. It is important to increase dosage until symptoms are controlled. Dosage should be increased more gradually in debilitated or emaciated patients. In continued therapy, gradually reduce dosage to the lowest effective maintenance level, after symptoms have been controlled for a reasonable period.

The 100 mg and 200 mg tablets are for use in severe neuropsychiatric conditions.

2.1 Important Administration Instructions

Instruct patients to administer APTIOM either as whole or as crushed tablets. Instruct patients to take APTIOM either with or without food.

2.2 General Dosing Recommendations

The recommended initial dosage of APTIOM is 400 mg once daily. For some patients, treatment may be initiated at 800 mg once daily if the need for seizure reduction outweighs an increased risk of adverse reactions during initiation [see Adverse Reactions (6.1)]. Dosage should be increased in weekly increments of 400 mg to 600 mg, based on clinical response and tolerability, to a recommended maintenance dosage of 800 mg to 1600 mg once daily. For patients on APTIOM monotherapy, the 800 mg once daily maintenance dose should generally be considered in patients who are unable to tolerate a 1200 mg daily dose. For patients on APTIOM adjunctive therapy, the 1600 mg daily dose should generally be considered in patients who did not achieve a satisfactory response with a 1200 mg daily dose.

2.3 Dosage Modifications with Other Antiepileptic Drugs

Some adverse reactions occur more frequently when patients take APTIOM adjunctively with carbamazepine [see Warnings and Precautions (5.6)]. However, carbamazepine reduces the plasma concentration of eslicarbazepine [see Drug Interactions (7.2)]. When APTIOM and carbamazepine are taken concomitantly, the dose of APTIOM or carbamazepine may need to be adjusted based on efficacy and tolerability. For patients taking other enzyme-inducing AEDs (i.e., phenobarbital, phenytoin, and primidone), higher doses of APTIOM may be needed [see Drug Interactions (7.2)].

APTIOM should not be taken as an adjunctive therapy with oxcarbazepine.

2.4 Dosage Modifications in Patients with Renal Impairment

In patients with moderate and severe renal impairment (i.e., creatinine clearance < 50 mL/min), the initial, titration, and maintenance dosages should generally be reduced by 50%. Titration and maintenance dosages may be adjusted according to clinical response [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

2.5 Patients with Hepatic Impairment

Dose adjustments are not required in patients with mild to moderate hepatic impairment. Use of APTIOM in patients with severe hepatic impairment has not been studied, and use in these patients is not recommended [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].

2.6 Discontinuation of APTIOM

When discontinuing APTIOM, reduce the dosage gradually and avoid abrupt discontinuation in order to minimize the risk of increased seizure frequency and status epilepticus [see Warnings and Precautions (5.7)].

Adults

Adjust dosage to individual and the severity of his condition, recognizing that the milligram for milligram potency relationship among all dosage forms has not been precisely established clinically. It is important to increase dosage until symptoms are controlled. Dosage should be increased more gradually in debilitated or emaciated patients. In continued therapy, gradually reduce dosage to the lowest effective maintenance level, after symptoms have been controlled for a reasonable period.

Increase parenteral dosage only if hypotension has not occurred. Before using IM, see Important Notes On Injection.

ELDERLY PATIENTS

In general, dosages in the lower range are sufficient for most elderly patients. Since they appear to be more susceptible to hypotension and neuromuscular reactions, such patients should be observed closely. Dosage should be tailored to the individual, response carefully monitored, and dosage adjusted accordingly. Dosage should be increased more gradually in elderly patients.

PSYCHOTIC DISORDERS

Increase dosage gradually until symptoms are controlled. Maximum improvement may not be seen for weeks or even months. Continue optimum dosage for 2 weeks; then gradually reduce dosage to the lowest effective maintenance level. Daily dosage of 200 mg is not unusual. Some patients require higher dosages (e.g., 800 mg daily is not uncommon in discharged mental patients).

Hospitalized Patients: Acute Schizophrenic or Manic States

IM: 25 mg (1 mL). If necessary, give additional 25 to 50 mg injection in 1 hour. Increase subsequent IM doses gradually over several days–up to 400 mg q4-6h in exceptionally severe cases–until patient is controlled. Usually the patient becomes quiet and cooperative within 24 to 48 hours and oral doses may be substituted.

Prompt Control of Severe Symptoms

IM: 25 mg (1 mL). If necessary, repeat in 1 hour. Subsequent doses should be oral, 25-50 mg tid.

NAUSEA AND VOMITING

IM: 25 mg (1 mL). If no hypotension occurs, give 25 to 50 mg q3-4h prn, until vomiting stops. Then switch to oral dosage.

During Surgery

IM: 12.5 mg (0.5 mL). Repeat in 1/2 hour if necessary and if no hypotension occurs. IV: 2 mg per fractional injection, at 2-minute intervals. Do not exceed 25 mg. Dilute to 1 mg/mL, i.e., 1 mL (25 mg) mixed with 24 mL of saline.

PRESURGICAL APPREHENSION

IM: 12.5 to 25 mg (0.5-1 mL), 1 to 2 hours before operation.

INTRACTABLE HICCUPS

If symptoms persist for 2-3 days after trial with oral therapy, give 25 to 50 mg (1-2 mL) IM. Should symptoms persist, use slow IV infusion with patient flat in bed: 25 to 50 mg (1-2 mL) in 500 to 1000 mL of saline. Follow blood pressure closely.

ACUTE INTERMITTENT PORPHYRIA

IM: 25 mg (1 mL) tid or qid until patient can take oral therapy.

TETANUS

IM:25 to 50 mg (1-2 mL) given 3 or 4 times daily, usually in conjunction with barbiturates. Total doses and frequency of administration must be determined by the patient’s response, starting with low doses and increasing gradually. IV: 25 to 50 mg (1-2 mL). Dilute to at least 1 mg per mL and administer at a rate of 1 mg per minute.

Pediatric Patients (6 months to 12 years of age)

Chlorpromazine should generally not be used in pediatric patients under 6 months of age except where potentially lifesaving. It should not be used in conditions for which specific pediatric dosages have not been established.

SEVERE BEHAVIORAL PROBLEMS Outpatients

Select route of administration according to severity of patient’s condition and increase dosage gradually as required. IM: 1/4 mg/lb body weight q6-8h, prn.

Hospitalized Patients

As with outpatients, start with low doses and increase dosage gradually. In severe behavior disorders, higher dosages (50-100 mg daily, and in older children, 200 mg daily or more) may be necessary. There is little evidence that behavior improvement in severely disturbed mentally retarded patients is further enhanced by doses beyond 500 mg per day. Maximum IM Dosage: Patients up to 5 years (or 50 lbs.), not over 40 mg/day;5-12 years (or 50-100 lbs.), not over 75 mg/day except in unmanageable cases.

NAUSEA AND VOMITING

Dosage and frequency of administration should be adjusted according to the severity of the symptoms and response of the patient. The duration of activity following intramuscular administration may last up to 12 hours. Subsequent doses may be given by the same route if necessary. IM: 1/4 mg/lb body weight q6-8h, prn. Maximum IM Dosage: Pediatric patients 6 months to 5 years (or 50 lbs.), not over 40 mg/day; 5-12 years (or 50-100 lbs.), not over 75 mg/day except in severe cases.

During Surgery

IM: 1/8 mg/lb body weight. Repeat in 1/2 hour if necessary and if no hypotension occurs. IV: 1 mg per fractional injection at 2-minute intervals and not exceeding recommended IM dosage. Always dilute to 1 mg/mL, i.e., 1 mL (25 mg) mixed with 24 mL of saline.

IM or IV: 1/4 mg/lb body weight q6-8h. When given IV, dilute to at least 1 mg/mL and administer at a rate of 1 mg per 2 minutes. In patients up to 50 lbs., do not exceed 40 mg daily; 50 to 100 lbs., do not exceed 75 mg except in severe cases.

Important Notes on Injection

Inject slowly, deep into upper outer quadrant of buttock.

Because of possible hypotensive effects, reserve parenteral administration for bedfast patients or for acute ambulatory cases, and keep patient lying down for at least 1/2 hour after injection. If irritation is a problem, dilute injection with saline or 2% procaine; mixing with other agents in the syringe is not recommended. Subcutaneous injection is not advised. AVOID INJECTING UNDILUTED CHLORPROMAZINE HYDROCHLORIDE INJECTION INTO VEIN. IV ROUTE IS ONLY FOR SEVERE HICCUPS, SURGERY AND TETANUS.

Because of the possibility of contact dermatitis, avoid getting solution on hands or clothing.

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

Adjust dosage to individual and the severity of his condition, recognizing that the milligram for milligram potency relationship among all dosage forms has not been precisely established clinically. It is important to increase dosage until symptoms are controlled. Dosage should be increased more gradually in debilitated or emaciated patients. In continued therapy, gradually reduce dosage to the lowest effective maintenance level, after symptoms have been controlled for a reasonable period.

The 100 mg and 200 mg tablets are for use in severe neuropsychiatric conditions.

 

In general, dosages in the lower range are sufficient for most elderly patients. Since they appear to be more susceptible to hypotension and neuromuscular reactions, such patients should be observed closely. Dosage should be tailored to the individual, response carefully monitored, and dosage adjusted accordingly. Dosage should be increased more gradually in elderly patients.

 

Increase dosage gradually until symptoms are controlled. Maximum improvement may not be seen for weeks or even months. Continue optimum dosage for 2 weeks; then gradually reduce dosage to the lowest effective maintenance level. Daily dosage of 200 mg is not unusual. Some patients require higher dosages (e.g., 800 mg daily is not uncommon in discharged mental patients).

 

It is recommended that initial treatment be with chlorpromazine HCl injection until patient is controlled. Usually patient becomes quiet and cooperative within 24 to 48 hours and oral doses may be substituted and increased until the patient is calm. 500 mg a day is generally sufficient. While gradual increases to 2,000 mg a day or more may be necessary, there is usually little therapeutic gain to be achieved by exceeding 1,000 mg a day for extended periods. In general, dosage levels should be lower in the elderly, the emaciated and the debilitated.

 

25 mg t.i.d. Increase gradually until effective dose is reached – usually 400 mg daily.

 

10 mg t.i.d. or q.i.d., or 25 mg b.i.d. or t.i.d.

 

25 mg t.i.d. After 1 or 2 days, daily dosage may be increased by 20 to 50 mg at semi-weekly intervals until patient becomes calm and cooperative.

 

Initial treatment should be with intramuscular chlorpromazine. Subsequent doses should be oral, 25 to 50 mg t.i.d.

 

10 to 25 mg q4 to 6h, p.r.n., increased, if necessary.

 

25 to 50 mg, 2 to 3 hours before the operation.

 

25 to 50 mg t.i.d. or q.i.d. If symptoms persist for 2 to 3 days, parenteral therapy is indicated.

 

25 to 50 mg t.i.d. or q.i.d. Can usually be discontinued after several weeks, but maintenance therapy may be necessary for some patients.

 

Chlorpromazine should generally not be used in pediatric patients under 6 months of age except where potentially lifesaving. It should not be used in conditions for which specific pediatric dosages have not been established.

 

Select route of administration according to severity of patient's condition and increase dosage gradually as required. Oral: ¼ mg/lb body weight q4 to 6h, p.r.n. (e.g., for 40 lb child – 10 mg q4 to 6h).

 

As with outpatients, start with low doses and increase dosage gradually. In severe behavior disorders higher dosages (50 to 100 mg daily and in older children, 200 mg daily or more) may be necessary. There is little evidence that behavior improvement in severely disturbed mentally retarded patients is further enhanced by doses beyond 500 mg per day.

 

Dosage and frequency of administration should be adjusted according to the severity of the symptoms and response of the patient. The duration of activity following intramuscular administration may last up to 12 hours. Subsequent doses may be given by the same route if necessary. Oral: ¼ mg/lb body weight (e.g., 40 lb child – 10 mg q4 to 6h).

 

¼ mg/lb body weight orally 2 to 3 hours before operation.

25 to 50 mg t.i.d. or q.i.d. If symptoms persist for 2 to 3 days, parenteral therapy is indicated.

Acute Intermittent Porphyria

25 to 50 mg t.i.d. or q.i.d. Can usually be discontinued after several weeks, but maintenance therapy may be necessary for some patients.

Chlorpromazine should generally not be used in pediatric patients under 6 months of age except where potentially lifesaving. It should not be used in conditions for which specific pediatric dosages have not been established.

Severe Behavioral Problems Outpatients

Select route of administration according to severity of patient's condition and increase dosage gradually as required. Oral: ¼ mg/lb body weight q4 to 6h, p.r.n. (e.g., for 40 lb child – 10 mg q4 to 6h).

Hospitalized Patients

As with outpatients, start with low doses and increase dosage gradually. In severe behavior disorders higher dosages (50 to 100 mg daily and in older children, 200 mg daily or more) may be necessary. There is little evidence that behavior improvement in severely disturbed mentally retarded patients is further enhanced by doses beyond 500 mg per day.

Nausea and Vomiting

Dosage and frequency of administration should be adjusted according to the severity of the symptoms and response of the patient. The duration of activity following intramuscular administration may last up to 12 hours. Subsequent doses may be given by the same route if necessary. Oral: ¼ mg/lb body weight (e.g., 40 lb child – 10 mg q4 to 6h).

Presurgical Apprehension

¼ mg/lb body weight orally 2 to 3 hours before operation.
