[Evaluation of the analgesic effect of UP 341-01 in patients presenting with acute pain in ORL].

The authors report the results obtained with a new analgesic, UP 341.01, which is a bioprecursor of paracetamol. Two groups of patients with acute pain, due to suppurative acute otitis media before myringotomy, were given an intravenous injection of 1 or 2 g of UP 341.01 respectively. Changes in the severity of pain were assessed over five hours by means of a verbal five point scoring system. During this study, UP 341.01 proved efficient and well tolerated.
