- Ability to swallow capsules without difficulty
- A Body Mass Index (BMI) between 11 and 50 kg/m2
- Reasonable probability for completion of the study
- Acceptable screening laboratory values. All laboratory values ≤ Grade I (e.g., creatine phosphokinase (CPK), amylase, triglycerides) are permissible if documentation of stability for 2 months or more is available. Abnormalities \> Grade I are subject to approval by BI clinical monitor or designee

- Stable doses of approved NRTIs and NNRTIs 2 for a minimum of twelve weeks prior to study Day 0. Subjects on efavirenz must be able to tolerate daily morning (8:00 a.m.) dosing starting at screening period and for 22 days of the study. Subjects receiving bid ddI must be willing to accept a change to the once a day delayed release (EC) formulation
Exclusion
- Female subjects who:
- have a positive serum pregnancy test at Screening Period Day -14 to -7
- are breast feeding
- Receipt of any other investigational medicine for 30 days prior to Day 0
- Receipt of any known cytochrome P450 3A4 (CYP3A4) altering drug i.e. phenothiazines, cimetidine, barbiturates, ketoconazole, fluconazole, rifampin, steroids and herbal medications for 30 days prior to Day 0. No antibiotics permitted within 10 days prior to Day 0

- Seated systolic blood pressure either \<100 mm Hg or \>150 mm Hg; resting heart rate either \<50 beats/minute or \>90 beats/minute
- History of any illness, including malabsorption, irregular food intake or gastrointestinal intolerance, or allergy that, in the opinion of the investigator, might confound the results of the study or pose additional risk in administering TPV/RTV
- Any acute illness within 2 weeks prior to Day 0
- Subjects who are currently taking any over-the-counter drug within 7 days prior to Day 0, or who are currently taking any prescription drug that, in the opinion of the investigator (in consultation with the BI medical monitor and/or pharmacokineticist), might interfere with either the absorption, distribution or metabolism of the TPV/RTV
- Hypersensitivity to TPV, RTV or sulfonamide containing drugs
- Using the adherence diary, subject has less than 100% documented adherence for the last 14 doses (7 days) of baseline antiretroviral medications prior to Day 0. Subjects has less than 100% adherence for the last 7 doses (7 days) of efavirenz and ddI (delayed release) prior to Day 0
