Hyperhidrosis: A Review of Recent Advances in Treatment with Topical Anticholinergics

BACKGROUND: Topical anticholinergics have been reported to be effective in managing hyperhidrosis (HH) given the recent approval of glycopyrronium tosylate. OBJECTIVE: This review aimed to examine the effectiveness of emerging topical anticholinergic treatments for HH and their associated adverse effects in comparison to current treatment options. METHODS: We conducted a search within the PubMed and Embase databases for current and emerging topical anticholinergic treatments for primary HH. RESULTS: The topical anticholinergics that have been recently investigated for use in HH include glycopyrrolate, oxybutynin, sofpironium bromide, and umeclidinium. The only agent currently FDA approved is glycopyrrolate. CONCLUSION: Knowledge of topical anticholinergic treatment options is important for patient care when managing HH. This review shows that while available safety data thus far are limited, emerging topical anticholinergics pose minimal known human risks.
