Indinavir was administered on an empty stomach with 200 mL tap water following an overnight fast.
A standard lunch (ham or turkey sandwich, potato salad, coleslaw, soft drink) was served following the 4-hour blood sample.
Eleven nonsmoking healthy subjects (6 males, 5 females) within 15% of ideal body weight and ranging in age from 21 to 47 years (mean 25.5 years) provided written informed consent and participated in the study. Subjects had no history of any chronic disease known to affect the metabolism and elimination of drugs. In addition, they did not take any prescription, over-the-counter, or herbal medicine known to influ- ence CYP3A4 activity for at least 1 month prior to the start of the study and were prohibited from taking these products throughout the study period. The study was approved by the Wayne State University Human Investigation Committee.
