This study aimed to compare the efficacy of tapentadol extended-release (ER) 50 mg and oxycodone controlled-release (CR), both given twice daily and placebo; plus a multimodal analgesic therapy both in-hospital and at home the first 7 days following TKA.
The patients after total knee arthroplasty (TKA) commonly
experience postoperative pain. This randomised clinical trial with 134 patients
based on the effectiveness of tapentadol ER and oxycodone CR as an add-on to
multimodal analgesia which portrayed tapentadol to be no good than oxycodone
concerning pain relief.
This study aimed to compare the efficacy of tapentadol
extended-release (ER) 50 mg and oxycodone controlled-release (CR), both given
twice daily and placebo; plus a multimodal analgesic therapy both in-hospital
and at home the first 7 days following TKA.
The study was randomized and blinded for researchers,
staff, outcome assessors and patients. Pain intensity on mobilization, pain at
rest, worst pain in the last 24 hours, and adverse effects assessed on 0-10
numeric rate scales was evaluated at follow-up.
Overall, 134 patients were divided into 3 groups. Primary
outcome pain on mobilization the 7 first postoperative days described as mean
pain Area Under the Curve (AUC) was 528.1 for placebo, 427.2 for tapentadol ER
and 507.9 for oxycodone CR. No significant differences between therapy groups
for the secondary outcomes were found except, constipation being less frequent
in the tapentadol ER group.
The use of tapentadol ER as an add-on to multimodal
analgesia did not provide significant pain relief than oxycodone CR or placebo.
