[Pharmacological action of anabolic steroids].
Anabolic steroids (AS) are derivatives of androgen (testosterone and its close relatives). AS have been primarily developed for clinical use as anabolic agents with the expectation that they would be relatively less androgenic than testosterone and its close relatives. Various AS are applied to clinical use, but none is free from androgenic activity. Relation between chemical structure and anabolic-androgenic potency of various AS is summarized. AS action in erythropoiesis operates through increased porphyrin formation and production of erythropoietin. Mechanism of AS action in bone formation is suggested that AS potentiate intestinal 1.25(OH)2D receptors. Identification of androgen receptors in normal human osteoblast-like cells suggest that AS act directly on receptor-mediated mechanism. The other action of AS is briefly summarized.
