Abstract and Introduction

Abstract

Hyperhidrosis is a condition characterized by excessive sweat production beyond which is physiologically necessary for thermal regulation. Affecting over 4.8% of the United States population, studies have shown that severe primary hyperhidrosis interferes with daily activities and can be considered intolerable, negatively impacting a patient's quality of life. Glycopyrronium tosylate is a topical anticholinergic agent that reduces sweat production by blocking the activation of acetylcholine receptors in peripheral sweat glands. In clinical trials, topical glycopyrronium tosylate, a pre-moistened cloth containing 2.4% glycopyrronium solution, was shown to be an effective, safe and non-invasive treatment for patients suffering from primary hyperhidrosis. This review examines the clinical trials of topical glycopyrronium tosylate and its role in primary hyperhidrosis. Glycopyrronium tosylate was recently US FDA-approved (as of June 2018) to manage patients with primary axillary hyperhidrosis.

Introduction

Hyperhidrosis is a condition characterized by sweat production beyond which is physiologically necessary for thermal regulation. A recent study estimates the prevalence of hyperhidrosis in the United States to be 4.8%, with over 70% of sufferers experiencing severe sweating that is considered intolerable or interfering with daily activities.[1]Hyperhidrosis has been shown to correlate with anxiety, depression and diminished quality of life.[2–5] Patients often report frustration with the length of time until diagnosis, as well as the cost and efficacy of treatments once a diagnosis is established.[4,5]
