The Influence of Raltegravir on Pravastatin Pharmacokinetics(GRAPPA)
The Influence of Raltegravir on Pravastatin Pharmacokinetics in Healthy Volunteers (GRAPPA)
The purpose of this trial is to determine the effect of raltegravir on pravastatin pharmacokinetics and vice versa by intrasubject comparison.

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.
