What is Qbrexza?
Qbrexza is a prescription anticholinergic medicine used on the skin (topical) to treat excessive underarm sweating (primary axillary hyperhidrosis) in adults and children 9 years of age and older.

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. The inactive ingredients are citric acid, dehydrated alcohol, purified water, and sodium citrate.
Glycopyrronium tosylate is chemically described as pyrrolidinium, 3-[(2-cyclopentyl-2-hydroxy-2-phenylacetyl)oxy]-1,1-dimethyl-, 4-methylbenzensulfonate, hydrate (1:1:1) with an empirical formula of C26H37NO7S and a molecular weight of 507.6. The structural formula is represented below:
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.
