Treatment of Axillary Bromhidrosis with Topical 2% Glycopyrronium Bromide Cream: A Prospective, Non-randomized, Open-label Study.

Topical glycopyrrolate is a well-established therapeutic option for focal hyperhidrosis; however, there are no data on its efficacy in the treatment of bromhidrosis.The objective of this open-label, non-randomized study was to investigate the efficacy and safety of a galenic formulation of 2% glycopyrronium bromide cream, in the treatment of bromhidrosis.Nineteen patients with bromhidrosis were prescribed a 2% glycopyrronium bromide cream, to apply in both axillae, every night, for 12 weeks. Malodor was assessed on a four-point scale. Scores for the Dermatology Life Quality Index (DLQI), Hyperhidrosis Disease Severity Scale (HDSS), and the Hospital Anxiety and Depression Scale (HADS) were recorded at baseline and after 12 weeks.Statistically significant improvements in malodor and HDSS, DLQI, and HADS scores, respectively, were observed after treatment. One patient reported irritation at the site of application and another reported mydriasis, which resolved spontaneously. All but one of the patients declared that they were either completely (52/6%) or partially (42.1%) satisfied regarding the treatment.Our results indicate that 2% glycopyrronium bromide cream is effective and safe for 12 weeks of application in patients with axillary bromhidrosis.
