Sofpironium bromide

A topical anticholinergic medication used for hyperhidrosis

Chemical structure of Sofpironium bromide

Sofpironium bromide is a topical anticholinergic medication primarily used for the treatment of hyperhidrosis, a condition characterized by excessive sweating. It is applied to the skin to reduce the activity of the sweat glands.

Mechanism of action

Sofpironium bromide works by blocking the action of acetylcholine on the muscarinic receptors in the sweat glands. This inhibition reduces the secretion of sweat, thereby alleviating the symptoms of hyperhidrosis. As an anticholinergic agent, it specifically targets the M3 muscarinic receptor subtype, which is predominantly involved in the regulation of sweat production.

Clinical use

Sofpironium bromide is indicated for the management of primary axillary hyperhidrosis, which affects the underarm area. It is applied topically, usually in the form of a gel or solution, and is designed for once-daily use. The medication is absorbed through the skin and acts locally to decrease sweat production.

Side effects

Common side effects of sofpironium bromide include local skin reactions such as redness, itching, and irritation at the site of application. Systemic side effects are rare due to the minimal absorption of the drug into the bloodstream. However, patients should be monitored for signs of anticholinergic effects, such as dry mouth, blurred vision, and urinary retention.

Development and approval

Sofpironium bromide was developed as a novel treatment option for patients with hyperhidrosis who do not respond adequately to other therapies. It has undergone clinical trials to establish its efficacy and safety profile. The medication has been approved for use in several countries and is marketed under various brand names.
