Patch Test Evaluation of Percutaneous Analgesics

Abstract

As contact dermatitis often occurs following application of percutaneous analgesic ointment, patch tests were performed using heparin-ointment, heparin gel-ointment. indomethacin ointment, ethofenamate ointment and the respective placeboes. Among these agents, indomethacin ointment provoked skin reaction which was significantly more potent than that of other agents, as determined in 36 dermatitis-free persons.
