Mode of action

IN-VITRO PROPOSED MOA OF WINLEVI®

Clascoterone is a novel androgen receptor inhibitor that when applied topically appears to target androgen receptors in the pilosebaceous unit.1,2,16

Proposed mode of action

The exact mechanism of action of clascoterone for the topical treatment of acne vulgaris is not fully characterised. In vitro findings may not accurately reflect in vivo phenomena.

Compete

Within the skin, clascoterone binds to androgen receptors, competing with the binding of androgens such as DHT.1

Inhibit

In-vitro studies suggest this inhibits the action of androgen receptors on cells in the sebaceous gland.1

Reduce

This allows to reduce sebum production and inflammation.1
