Pharmacokinetics, safety, and tolerability of BAY 12-9566 and nonsteroidal anti-inflammatory agents (naproxen, ibuprofen) during coadministration in patients with osteoarthritis.

| Abstract |
The pharmacokinetic interactions between BAY 12-9566 and two nonsteroidal anti-inflammatory drugs (NSAIDs), naproxen and ibuprofen, were investigated in osteoarthritis (OA) patients. The study comprised six groups: two NSAID groups with three levels of treatment (BAY 12-9566 400 mg, BAY 12-9566 100 mg, and placebo). Plasma pharmacokinetic parameters (AUC(0-tau), Cmax, and tmax) were determined for each treatment group following 5 days of NSAID administration, 14 days of BAY 12-9566 administration, and 14 days of concurrent NSAID and BAY 12-9566 administration. For most conditions, the total plasma drug concentrations of both NSAID and BAY 12-9566 were diminished by coadministration; total plasma BAY 12-9566 was not affected by ibuprofen treatment. Importantly, the free drug concentrations were largely unaffected by coadministration. Most side effects were mild or moderate in intensity, and all events, with the exception of headache, were reported in both NSAID groups and in both placebo and BAY 12-9566 groups.
