ChemBioChem. 2012, 13 (8): 1161–1166.

[...] 11α-Hydroxyprogesterone can therefore influence blood pressure regulation.12 Furthermore, 11α-hydroxyprogesterone exhibits an anti-androgenic activity with minimal estrogenic and progestational side effects.13 This substance was also recently patented for its role in treating skin diseases, especially for psoriasis in combination with clobetasol propionate and minoxidil.14.
