In a phase I/II study, 7 levels of 3TC therapy (from 0.5 to 20.0 mg/kg/day) were studied in 104 asymptomatic and mildly symptomatic human immunodeficiency virus-infected patients with CD4 cell counts < or = 400 x 10(6)/L. Mild and transient episodes of diarrhea, headache, fatigue, nausea, and abdominal pain were the most frequent events reported. No dose-limiting toxicities were observed. Small and transient increases in CD4 cell counts were detected during the first 4 weeks of treatment. These were followed by progressive declines during prolonged therapy. Sustained decreases in beta 2-microglobulin, neopterin, and p24 antigen levels were seen over the 52-week study. There was no consistent dose-response correlation for any surrogate marker. Penetration of 3TC into cerebrospinal fluid (CSF) was in the same range as reported for ddC and ddI; the mean CSF-to-serum ratio was 0.06. These findings indicate that 3TC exhibits an excellent safety profile and has antiretroviral activity at the dosages studied.

Information on dosage, cost, side effects, and interactions is provided for each of the seven nucleoside analog drugs available currently: Retrovir (AZT, ZDV), Videx (ddI), Hivid (ddC), Zerit (d4T), Epivir (3TC), Combivir (AZT/3TC), and Ziagen (abacavir sulfate). Most nucleoside analogs (with the exception of ddI) do not have food restrictions, but do have potential side effects such as nausea and fatigue. An activist, a doctor, and the drug's manufacturer offer comments. Contact information is provided.
