Review looks at effectiveness of isotretinoin for acne

The authors took special note of the low-quality evidence in the review, and said that future studies should include larger sample sizes to observe more rare adverse events, as well as create subgroups with results based on acne severity, longer duration and follow-up, standardization of primary outcomes, and adherence to the 2010 CONSORT statement for reporting parallel-group randomized trials.

“With the aim of providing reliable physician guidelines and a robust evidence-based support for daily clinical practice in acne therapy, future randomized clinical trials on oral isotretinoin for acne should focus on treatment of acne when there is insufficient response to therapy with oral antibiotics plus topical agents,” Dr. Costa and her colleagues wrote.

Dr. Costa reports receiving a grant from the Brazilian government granting agency Coordenação de Aperfeicoamento de Pessoal de Nivel Superior. Another author reported a board membership with Bayer for studies and research and is a paid lecturer for a continuing medical education program on adult female acne. The remaining five authors reported no relevant conflicts of interest.
