Analgesic efficacy of parenteral paracetamol (propacetamol) and diclofenac in post‐operative orthopaedic pain

Abstract

Both active treatments were superior to placebo, and the overall efficacy of two intravenous infusions of propacetamol 2 g (equivalent to 1 g of paracetamol), 5 h apart, was not statistically different from that provided by a single intramuscular injection of diclofenac 75 mg over the first 5 h post-dose and over the total 10-h study period. The safety was good.
