Summary
Background: - People who have the human immunodeficiency virus (HIV) often take several medications to control their disease. They may also need to take medicine to prevent blood clots. Taking both kinds of medicine together can cause bleeding or other problems. But this might not happen if the medications are taken at different times. Researchers will study two particular HIV drugs (ritonavir and cobicistat) and how they interact with blood clot medications. Objectives: -To understand how HIV medicine and blood clot medicine interact, so doctors can choose what to prescribe for people who take both. Eligibility: - Healthy adults between 18 and 70 years old who are not on any medications. Design: - Participants will be screened with a physical exam and medical history. Blood samples will be collected. Urine samples will be collected from participants who might become pregnant. - Participants will visit the National Institutes of Health 7 times after the screening visit. Three visits will last about 12 hours. The other 4 will last about 1 hour. - Participants will take a daily dose of either study medication for 22 days. They will keep a diary of medicine they take and any side effects. - Treatment will be monitored with blood tests over about 2 months. - When the study of one drug is completed, the next drug study will begin with a different group of participants.
