Use of PregnanolonePregnanolone, also known as 3a5b-Pregnanolone; Kabi-2213, SKF 6455, Eltanolone, is a cell membrane modulator potentially for the treatment of pain. Pregnanolone is an endogenous neurosteroid that is biosynthesized from progesterone. It is a positive allosteric modulator of the GABAA receptor, as well as a negative allosteric modulator of the glycine receptor, and is known to have sedative, anxiolytic, anesthetic, and anticonvulsant effects. It was investigated for clinical use as a general anesthetic, but produced unwanted side effects such as convulsions on occasion, and for that reason was never marketed. |
