intensity compared to patients in the placebo group (p=0.021). When both dose groups of tapentadol were compared to the oxycodone arm of the study (added as sensitivity control of the model), tapentadol ER 100 mg bid was found to be similar to oxycodone HCl CR 20 mg bid, providing further support that the analgesic efficacy of tapentadol is in the range of other strong centrally acting analgesics.
Safety and Tolerability
- In general, the most common adverse events in all groups were typical for a treatment with centrally acting analgesics. With respect to gastrointestinal (e.g. nausea, vomiting, constipation) and CNS (e.g.
somnolence, dizziness) side effects, the data suggest an improved tolerability of tapentadol compared to oxycodone. The incidence of constipation with both tapentadol ER 100 mg (7%) and 200 mg (10%) was less than or equal to half of the incidence associated with oxycodone CR 20 mg (20%).
