A Two Way Cross Over Pharmacokinetic (PK) Interaction Study Between Raltegravir and Amlodipine in Healthy Volunteers

Detailed Summary

The purpose of the study is to look at the levels of an HIV medication (raltegravir) in the blood, and how it is affected if raltegravir is taken at the same time as another medicine for high blood pressure (amlodipine). Many patients with HIV will also have high blood pressure, so it is important to know which drugs for each of these conditions can be taken together without affecting how well they work individually. Over a 3 week period, participants took amlodipine for 2 weeks, and raltegravir for 2 weeks, with the middle week being on both drugs. The investigators will look at and compare the levels of these two drugs in the blood after subjects have taken them separately and both together. This study is randomised into two groups with both study medications received by all participants in a three-period crossover pattern; randomisation determined which medication was taken first. Once randomised allocation was performed, medications were administered in an open-label fashion.
