Clinical evaluation of allicin oral adhesive tablets in the treatment of recurrent aphthous ulceration

Abstract

We investigated the effectiveness and safety of topical application of 5 mg allicin adhesive tablets in the treatment of minor recurrent aphthous ulcerations (MiRAU). A randomized, double-blinded, placebo-controlled, clinical trial was performed. Tablets containing 5 mg allicin or vehicle only were consecutively applied 4 times per day for 5 days. The size and pain level of ulcers were measured and recorded on days 1, 2, 4, and 6. A total of 96 subjects with MiRAU fulfilled the study. Allicin adhesive tablets significantly reduced ulcer size (P < .005, P < .003, P < .001 for days 2, 4, and 6, respectively) and alleviated ulcer pain score (P < .03, P < .001, P < .05 for days 2, 4, and 6, respectively) compared with vehicle tablets. Minor and major adverse reactions were not observed. Allicin adhesive tablets were effective in reducing ulcer size and alleviating ulcer pain of the patients in the treatment of MiRAU without significant side effects.
