Comparison of acidifying agents and clotrimazole for treatment of otomycosis: a comprehensive one-way mini-review

This review aimed to compare the efficacy of acidifying agents and clotrimazole in the treatment of patients with otomycosis.

The databases, including Research Gate, Google Scholar,ScienceDirect, Embase, Medline, Scopus, Cochrane, and library databases of clinical trials were searched in this study. The keywords were "Fungal Ear Infection" and "Otitis External" for otomycosis, "Clotrimazole", Lotrimin", "Mycelex", "Desenex", and "Clotrimaderm Mycoderm" for clotrimazole, and "Boric Acid Alcohol", "Alcohol-vinegar solution", Burow solution (Domeboro), "Isopropyl Alcohol", "VoSol" and "Acetic Acid" for acidifying agents. Regarding search strategy, a total of 53 studies were collected, 11 of which were maintained for assessment. Almost all studies were published after 1990. These articles discussed the role of clotrimazole and acidifying compounds in the treatment of otomycosis. Moreover, the route of administration, dosage, and side effects of these medications were highlighted.

Eight studies had similar results and claimed that clotrimazole has the best or most significant effect on the treatment of otomycosis for patients suffering from pain,itching, swelling, and hearing loss.

Although all medications appear effective, there is a paucity of evidence to fully support the decision to choose between clotrimazole or acidifying agents for the treatment of otomycosis in terms of both efficacy and safety. However, in the biomedical field, the re-emerging investigation attention is due to the statements of a number of mechanisms defending the use of acidifying agents to treat mycosis (of antifungal-resistant species).
