Uses
RETROVIR, a nucleoside reverse transcriptase inhibitor, is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection.
RETROVIR is indicated for the prevention of maternal-fetal HIV-1 transmission [see Dosage and Administration (2.3)]. The indication is based on a dosing regimen that included 3 components:
- •
- antepartum therapy of HIV-1 infected mothers
- •
- intrapartum therapy of HIV-1 infected mothers
- •
- post-partum therapy of HIV-1 exposed neonate
Points to consider prior to initiating RETROVIR in pregnant women for the prevention of maternal-fetal HIV-1 transmission include:
- •
- In most cases, RETROVIR for prevention of maternal-fetal HIV-1 transmission should be given in combination with other antiretroviral drugs.
- •
- Prevention of HIV-1 transmission in women who have received RETROVIR for a prolonged period before pregnancy has not been evaluated.
- •
- Because the fetus is most susceptible to the potential teratogenic effects of drugs during the first 10 weeks of gestation and the risks of therapy with RETROVIR during that period are not fully known, women in the first trimester of pregnancy who do not require immediate initiation of antiretroviral therapy for their own health may consider delaying use; this indication is based on use after 14 weeks gestation.
History
There is currently no drug history available for this drug.
Other Information
RETROVIR is the brand name for zidovudine (formerly called azidothymidine [AZT]), a pyrimidine nucleoside analogue active against HIV-1. The chemical name of zidovudine is 3′-azido-3′-deoxythymidine; it has the following structural formula:
Zidovudine is a white to beige, odorless, crystalline solid with a molecular weight of 267.24 and a solubility of 20.1 mg per mL in water at 25°C. The molecular formula is C10H13N5O4.
RETROVIR capsules are for oral administration. Each capsule contains 100 mg of zidovudine and the inactive ingredients corn starch, magnesium stearate, microcrystalline cellulose, and sodium starch glycolate. The 100-mg empty hard gelatin capsule, printed with edible black ink, consists of black iron oxide, dimethylpolysiloxane, gelatin, pharmaceutical shellac, soya lecithin, and titanium dioxide.
RETROVIR syrup is for oral administration. Each mL of RETROVIR syrup contains 10 mg of zidovudine and the inactive ingredients sodium benzoate 0.2% (added as a preservative), citric acid, flavors, glycerin, and liquid sucrose. Sodium hydroxide may be added to adjust pH.
RETROVIR injection is a sterile solution for IV infusion only. Each mL contains 10 mg zidovudine in water for injection. Hydrochloric acid and/or sodium hydroxide may have been added to adjust the pH to approximately 5.5. RETROVIR injection contains no preservatives. The vial stoppers for RETROVIR injection contain natural rubber latex.

2.1 Adults - Treatment of HIV-1 InfectionOral Dosing
The recommended oral dose of RETROVIR is 300 mg twice daily in combination with other antiretroviral agents.
Intravenous (IV) Dosing
The recommended intravenous dose is 1 mg per kg infused at a constant rate over 1 hour every 4 hours. Patients should receive RETROVIR injection only until oral therapy can be administered.
• RETROVIR injection must be diluted prior to administration. The calculated dose should be removed from the 20 mL vial and added to 5% Dextrose injection solution to achieve a concentration no greater than 4 mg per mL. • After dilution, the solution is physically and chemically stable for 24 hours at room temperature and 48 hours if refrigerated at 2° to 8°C (36° to 46°F). As an additional precaution, the diluted solution should be administered within 8 hours if stored at 25°C (77°F) or 24 hours if refrigerated at 2° to 8°C to minimize potential administration of a microbially contaminated solution. • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit and discarded if either is observed. • Rapid infusion or bolus injection should be avoided. RETROVIR injection should not be given intramuscularly. 2.2 Pediatric Patients (Aged 4 Weeks to Less than 18 Years)Healthcare professionals should pay special attention to accurate calculation of the dose of RETROVIR, transcription of the medication order, dispensing information, and dosing instructions to minimize risk for medication dosing errors.
Prescribers should calculate the appropriate dose of RETROVIR for each child based on body weight (kg) and should not exceed the recommended adult dose.
Before prescribing RETROVIR capsules, children should be assessed for the ability to swallow capsules. If a child is unable to reliably swallow a RETROVIR capsule, the RETROVIR syrup formulation should be prescribed.
The recommended oral dosage in pediatric patients aged 4 weeks to less than 18 years and weighing greater than or equal to 4 kg is provided in Table 1. RETROVIR syrup should be used to provide accurate dosage when capsules are not appropriate.

Alternatively, dosing for RETROVIR can be based on body surface area (BSA) for each child. The recommended oral dose of RETROVIR is 480 mg per m2 per day in divided doses (240 mg per m2 twice daily or 160 mg per m2 three times daily). In some cases the dose calculated by mg per kg will not be the same as that calculated by BSA.
2.3 Prevention of Maternal-Fetal HIV-1 TransmissionThe recommended dosage regimen for administration to pregnant women (greater than 14 weeks of pregnancy) and their neonates is:
Maternal Dosing
100 mg orally 5 times per day until the start of labor [see Clinical Studies (14.3)]. During labor and delivery, intravenous RETROVIR should be administered at 2 mg per kg (total body weight) over 1 hour followed by a continuous intravenous infusion of 1 mg per kg per hour (total body weight) until clamping of the umbilical cord.
Neonatal Dosing
Start neonatal dosing within 12 hours after birth and continue through 6 weeks of age. Neonates unable to receive oral dosing may be administered RETROVIR intravenously. See Table 2.

2.4 Patients with Severe Anemia and/or NeutropeniaSignificant anemia (hemoglobin less than 7.5 g per dL or reduction greater than 25% of baseline) and/or significant neutropenia (granulocyte count less than 750 cells per mm3 or reduction greater than 50% from baseline) may require a dose interruption until evidence of marrow recovery is observed [see Warnings and Precautions (5.1)]. In patients who develop significant anemia, dose interruption does not necessarily eliminate the need for transfusion. If marrow recovery occurs following dose interruption, resumption in dose may be appropriate using adjunctive measures such as epoetin alfa at recommended doses, depending on hematologic indices such as serum erythropoietin level and patient tolerance.
2.5 Patients with Renal ImpairmentIn patients maintained on hemodialysis or peritoneal dialysis or with creatinine clearance (CrCl) by Cockcroft-Gault less than 15 mL per min, the recommended oral dosage is 100 mg every 6 to 8 hours. The intravenous dosing regimen equivalent to the oral administration of 100 mg every 6 to 8 hours is approximately 1 mg per kg every 6 to 8 hours [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
2.6 Patients with Hepatic ImpairmentThere are insufficient data to recommend dose adjustment of RETROVIR in patients with impaired hepatic function or liver cirrhosis. Frequent monitoring of hematologic toxicities is advised [see Use in Specific Populations (8.7)].
