A double-blind study of the effect of zinc and oxytetracycline in acne vulgaris.


With a double-blind technique, the effects of oral zinc and tetracyclines were compared in 37 patients with moderate and severe acne. No difference in effect between the treatments was seen and no side-effects were noted in any group. After 12 weeks of treatment, the average decrease in the acne score was about 70% in both groups.
