Detailed description
Single-centre, open-label, randomised, two-way cross-over study consisting of 2 periods separated by a washout period of 14 days or more. In one period, subjects received three single-doses of 1 g paracetamol separated by 6 hours and 1.5 hours after the last paracetamol dose a single-dose of 50 mg OPC was administered.In the other period, a single-dose of 50 mg OPC was administered alone.
Interventions
