详情描述
Clascoterone, also known as CB-03-01 and cortexolone 17alpha-propionate, is a topical and peripherally selective and potent androgen antagonist for topical treatment of acne vulgaris. CB-03-01 1% cream seems to fit with the profile of an ideal antiandrogen for topical use. CB-03-01 is clinically more effective than comparator. Acne vulgaris is a disorder of the pilosebaceous unit in which the androgens contribute to its onset and persistence. The use of antiandrogens is therefore potentially effective.

How to use
In Vivo:
Clascoterone is a new potent topical antiandrogen potentially useful in acne vulgaris. Clascoterone 1% cream was very well tolerated, and was significantly better than placebo regarding TLC (P = 0·0017), ILC (P = 0·0134) and ASI (P = 0·0090), and also clinically more effective than comparator. The product also induced a faster attainment of 50% improvement in all the above parameters.
