Scientific titleCost-effectiveness analysis of oral paracetamol and ibuprofen for treating pain after soft tissue limb injuries: double-blind, randomised controlled trial
Study objectivesWe hypothesise firstly that paracetamol 1 g and ibuprofen 400 mg administered orally for soft tissue injuries have equal analgesic efficacy; secondly that paracetamol has less adverse effects than ibuprofen; and that when all additional health care related costs are taken into account, that paracetamol will be the more cost-effective option.
Ethics approval(s)Ethics approval received from the Joint Chinese University of Hong Kong - New Territories East Cluster (CUHK-NTEC) Clinical Research Ethics Committee on the 8th October 2004 (ref: CRE-2004.266-T).
Health condition(s) or problem(s) studiedSoft Tissue Injuries
InterventionArm 1: Paracetamol 1 g four times daily (qid) and ibuprofen placebo equivalent to 400 mg three times daily (tid)
Arm 2: Paracetamol placebo equivalent to 1 g qid and ibuprofen 400 mg tid
Arm 3: Paracetamol 1 g qid and ibuprofen 400 mg tid

Treatment will continue for three days, follow-up will continue for 30 days.

PhaseNot Specified
Drug / device / biological / vaccine name(s)Paracetamol, ibuprofen
Primary outcome measure(s)

Analgesic efficacy both at rest and with movement at 72 hours.
