Overview
11 DESCRIPTION Qbrexza (glycopyrronium) cloth, 2.4% is an anticholinergic drug available as a clear, colorless to pale yellow solution on a single-use pre-moistened cloth (an absorbent polypropylene pad) packaged in a pouch for topical administration. Each pouch contains 105 mg glycopyrronium tosylate, equivalent to 66 mg of glycopyrronium.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Glycopyrronium is a competitive inhibitor of acetylcholine receptors that are located on certain peripheral tissues, including sweat glands. In hyperhidrosis, glycopyrronium inhibits the action of acetylcholine on sweat glands, reducing sweating. 12.2 Pharmacodynamics The pharmacodynamics of Qbrexza are not known. 12.3 Pharmacokinetics Absorption The pharmacokinetics of glycopyrronium were evaluated in adult and pediatric patients with primary axillary hyperhidrosis following Qbrexza once daily applied to the axillae for 5 days. The mean ± SD exposures of glycopyrronium are presented in Tables 3 and 4. There was no evidence of accumulation.
