Official title
Evaluation of Potential Pharmacokinetic Interactions Between HIV Protease Inhibitors and Calcium Channel Blockers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Diltiazem CD and amlodipine are drugs used to treat heart disease and high blood pressure. The purpose of this study is to find out if these drugs interact with the anti-HIV drugs indinavir and ritonavir. The study will also look at the safety of taking the study drugs together. Heart disease and high blood pressure are major health concerns for people with HIV. Standard treatment for these illnesses often includes calcium channel blockers (CCBs). There is a potential for significant drug interactions between CCBs and HIV protease inhibitors (PIs) that may influence the dosing, monitoring, and choosing of CCBs and PIs when used in people infected with HIV. This study will examine the drug interactions between 2 commonly used CCBs and the PI combination indinavir and ritonavir (IDV/RTV). This information should help doctors choose the appropriate treatment for high blood pressure or heart disease in people taking PIs.
