Minocycline versus co-trimoxazole in chancroid : A double-blind randomised study

Abstract

This double-blind randomised parallel-group study comparing the efficacy and side effects of minocycline with that of cotrimoxazole in chancroid, had 56 analysable cases, 28 in each group. All admissible cases were assessed clinically on a scale of 0 to 3 for number and size of ulcers, pain, discharge, surrounding erythema and bubo. Each drug individually showed significant improvement in all clinical parameters. Minocycline showed significantly better improvement than cotrimoxazole in all parameters. Minocycline had 43% cure rate, and no failures, against 36% cure and 25% failure for cotrimoxazole. Both the drug were well tolerated. We conclude that minocycline is a superior alternative to cotrimoxazole in the therapy of chancroid.
