Study Description
Brief Summary:
Study of genetic polymorphisms of CYP #A and MDR-1 genes in Thai HIV-1 infected patients on saquinavir/ritonavir.

Condition or disease Intervention/treatment
HIV Infections Genetic: identify genetic polymorphism in Thai HIV infected

Detailed Description:
Genetic polymorphisms will be investigated by polymerase-chain reaction (PCR) and drug levels of saquinavir will be determined by high phase liquid chromatography with UV-detected (HPLC).
