Phase 1 Pharmacokinetic Study of Tapentadol Prolonged-Release 250 Milligram (mg) Formulation in Healthy Participants

An Open-Label, Sequential Treatment Study to Assess the Single and Multiple Dose Pharmacokinetics of a New Tapentadol Prolonged-Release 250 mg Formulation in Healthy Subjects

The purpose of this study is to evaluate pharmacokinetics (explores what the body does to the drug), safety and tolerability of single and multiple-dose of tapentadol in healthy participants.

This is an open-label (all people know the identity of the intervention), single-center, Phase 1 and, single and multiple-dose study of tapentadol tamper resistant prolonged-release formulation (TRF) 250 milligram (mg) tablet in healthy participants. The total study duration will be approximately of 29 days per participant. The study consists of 3 parts: Screening (that is, 21 days before study commences on Day 1); Treatment (single-dose of tapentadol on Day 1, and multiple dose from Day 4-6 [followed by washout period of 24 hours]); and End-of-study (Day 8). All the eligible participants will receive single oral dose of tapentadol TRF 250 mg on Day 1 and twice daily from Day 4-6 (total 5 doses). Participants will keep upright position until 4 hours after study drug administration. Study drug will be administered 30 minutes after breakfast in the morning. Blood samples will be collected for evaluation of pharmacokinetics at pre-dose and post-dose of study treatment. Participants' safety will be monitored throughout the study.
