Study to Evaluate the Effect of Multiple Doses of BIRT 2584 XX Tablets on the Pharmacokinetic Parameters of Midazolam in Healthy Male Volunteers

A Study to Evaluate the Effect of Multiple Doses of 500 mg of BIRT 2584 XX Tablets on the Pharmacokinetic Parameters of Midazolam in Healthy Male Volunteers

The objective of the study was to investigate the effect of BIRT 2584 XX and its metabolite BI 610100 when BIRT 2584 XX is administered as a tablet to near steady state in estimated high therapeutic dose on the pharmacokinetics (PK) of midazolam, a probe substrate for CYP3A4. The PK of midazolam was measured before dosing of BIRT 2584 XX, after a single dose of BIRT 2584 XX and after repeated doses of BIRT 2584 XX for 3 and 12 days
