Official title
The Effect of Efavirenz and Nelfinavir on the Pharmacokinetics of Hydroxymethylglutaryl Coenzyme A Reductase Inhibitors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to find out whether certain anti-HIV drugs (efavirenz \[EFV\] and nelfinavir \[NFV\]) affect the amount of certain fat-lowering drugs (atorvastatin, pravastatin, and simvastatin) in the blood. Protease inhibitors (PIs), a type of anti-HIV drug, are known to cause increased lipids (fats) in the blood of HIV-infected patients. EFV also is known to increase blood fats. HIV-infected patients who take PIs and/or EFV may need to take fat-lowering drugs to correct this problem. So it is important to look at possible drug interactions when these drugs are taken together. This study will see if taking EFV or NFV, a protease inhibitor, affects the blood level of simvastatin, atorvastatin, or pravastatin (all fat-lowering drugs). To obtain results more quickly, the study population will be healthy HIV-negative volunteers.
