Primary Outcome Measures:
- Plasma concentrations of pravastatin and raltegravir. [ Time Frame: t=0 (predose), 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 10, 12 and (24: for pravastatin only) hours post ingestion on Days 4, 18 and 32. Trough level on Day 2, 16 and 30. ]
Secondary Outcome Measures:
- To investigate the non-steady state changes in serum low density lipoprotein (LDL) cholesterol secondary to pravastatin use in the presence or absence of raltegravir [ Time Frame: Screening and Days 1, 5, 15, 19, 29 and 33. ]
- Determination of pharmacokinetic parameters [ Time Frame: at each sampling time ]
- To evaluate the safety of combined use of pravastatin and raltegravir [ Time Frame: entire trial ]

Detailed Description:
Pravastatin is a first choice statin for HIV-infected patients. Therefore, raltegravir and pravastatin are expected to be co-administered frequently in HIV-infected patients.Since both agents share the same metabolic pathway, there is a potential for a pharmacokinetic drug-drug interaction.
Because co-administration will be indicated in many HIV-infected patients, it is essential to investigate this potential interaction.
