Epiestriol (INNTooltip International Nonproprietary Name) (brand namesActriol,Arcagynil,Klimadoral), orepioestriol (BANTooltip British Approved Name), also known as16β-epiestriol or simply16-epiestriol, as well as16β-hydroxy-17β-estradiol, is a minor and weakendogenousestrogen, and the 16β-epimer ofestriol (which is 16α-hydroxy-17β-estradiol).[1][2] Epiestriol is (or has previously been) used clinically in the treatment ofacne.[1] In addition to its estrogenic actions, epiestriol has been found to possess significantanti-inflammatory properties withoutglycogenic activity orimmunosuppressive effects, an interesting finding that is in contrast to conventional anti-inflammatory steroids such ashydrocortisone (aglucocorticoid).[3][4]
