Inhibition of M1 receptor- and M3 receptor-mediated currents
REVIEW Pregnenolone is an endogenous steroid hormone involved in the steroidogenesis of progestogens, mineralocorticoids, glucocorticoids, androgens, and estrogens, as well as the neuroactive steroids. As such it is a prohormone, though it also has biological effects of its own, behaving namely as a neuroactive steroid in its own right with potent anxiolytic effects. Pregnenolone is also being considered as a potential treatment for schizophrenia.
