Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Ahmed Zaghw, M.D. [2]
Indications and Usage
ZERIT® (stavudine), in combination with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus (HIV)-1 infection [see Clinical Studies (14)].
DOSAGE AND ADMINISTRATION
The interval between doses of ZERIT (stavudine) should be 12 hours. ZERIT may be taken with or without food.
Recommended Adult Dosage
The recommended adult dosage is based on body weight as follows:
For patients weighing less than 60 kg: 30 mg every 12 hours. For patients weighing at least 60 kg: 40 mg every 12 hours.
Recommended Pediatric Dosage
For newborns from birth to 13 days old: 0.5 mg/kg given every 12 hours. For pediatric patients at least 14 days old and weighing less than 30 kg: 1 mg/kg given every 12 hours. For pediatric patients weighing at least 30 kg: use the recommended adult dosage.
Dosage Adjustment
Renal Impairment
'Adult Patients: ZERIT may be administered to adult patients with impaired renal function with an adjustment in dosage as shown in Table 1.
 |
Pediatric Patients: Since urinary excretion is also a major route of elimination of stavudine in pediatric patients, the clearance of stavudine may be altered in children with renal impairment. There are insufficient data to recommend a specific dose adjustment of ZERIT in this patient population.
Method of Preparation for Oral Solution
Prior to dispensing, the pharmacist must constitute the dry powder with purified water to a concentration of 1 mg stavudine per mL of solution, as follows:
Add 202 mL of purified water to the container. Shake container vigorously until the powder dissolves completely. Constitution in this way produces 200 mL (deliverable volume) of 1 mg/mL stavudine solution. The solution may appear slightly hazy. Dispense solution in original container with measuring cup provided. Instruct patient to shake the container vigorously prior to measuring each dose and to store the tightly closed container in a refrigerator, 2°C to 8°C (36°F to 46°F). Discard any unused portion after 30 days.
