Abstract:
Nevirapine and indinavir have the potential of affecting the pharmacokinetics of each other. In a prospective trial, 24 human immunodeficiency virus (HIV)-infected subjects on stable nucleoside or no therapy were treated with 800 mg of indinavir every 8 h. After 7 days, 200 mg of nevirapine a day was added for 14 days and then increased to 200 mg twice a day. At day 7 (before nevirapine), there was a sevenfold difference among the subjects in indinavir area under the curve (AUC), and there was a significant correlation between indinavir AUC (r2=0.378, P=.019), minimum plasma concentration (Cmin; r2=0.359, P=.023), maximum plasma concentration (Cmax; r2=0.340, P=.028), and plasma HIV RNA decline. Nevirapine significantly reduced median indinavir Cmin (47.5%) and AUC (27.4%) and, to a lesser extent, Cmax (11%). Plasma HIV RNA values were =20 copies/mL in 10 of 17 (58.8%) subjects at 58 weeks or last visit. These data suggest that indinavir dosing should be dependent on drug exposure and not on cotherapy with nevirapine.
