Interventions

DRUG

ritonavir and saquinavir

saquinavir/ritonavir 1500/100 mg or 1500/50 mg Twenty HIV-infected volunteers on stable doses of SQV/RTV 1500/100 mg OD for at least 3 months with an NRTI backbone and undetectable viral load will participate. After collecting samples for a full PK curve subjects will be switched to SQV/RTV 1500 /50 mg OD + 2NRTIs for 1 week before repeating the PK assessment. Blood samples will be drawn at T 0, 1, 2, 4, 6, 8, 10, 12 and 24 hours post ingestion. Consecutively to the assessment, subjects will return to SQV/RTV 1500/100 mg OD dosage.
