To determine the trough and two hour plasma levels of nevirapine, stavudine, and lamivudine when administered in fixed dose combinations (FDC). Cross sectional Tertiary care hospital in Northern India. 79 HIV-infected children receiving antiretroviral therapy with FDCs for more than month. Two-point sampling (0 and 2 hours after the morning dose). Plasma concentrations of all three drugs were simultaneously assayed by liquid chromatography/mass spectroscopy. Majority (77%) of children were receiving fixed dose combination of stavudine, lamivudine, nevirapine in the ratio of 6:30:50mg. The median (IQR) trough and 2-hour plasma levels (mu g/mL) of nevirapine, stavudine and lamivudine were 5.2 (4.0, 6.3) and 7.9 (6.0, 9.7); 0.1 (0.06, 0.16) and 1.1 (0.59, 1.6); 0.1 (0.02, 0.2) and 2.5 (1.4, 3.1), respectively. Very few children had sub-therapeutic plasma drug levels of stavudine (2.5%), lamivudine (7.6%) and nevirapine (10%). Inadequate viral suppression at 6 months follow up was significantly associated with initial high viral load, low CD4 percentage at the time of enrolment in study, and lower doses of lamivudine and stavudine. The currently available generic pediatric fixed dose antiretroviral combinations in India provide adequate drug exposure in majority of children.
