Pregnenolone, sold under the brand name Enelone among others, is a medication and supplement as well as a naturally occurring and endogenous steroid. [3] [1] [4] [5] [6] It is described as a neurosteroid and anti-inflammatory drug and was used in the treatment of rheumatoid arthritis and soft-tissue rheumatism in the 1950s and is no longer prescribed today, but remains available as a supplement.
Pregnenolone sulfate, also known as pregn-5-en-3β-ol-20-one 3β-sulfate, is a naturally occurring pregnane steroid and a derivative of cholesterol. It is the C3β sulfate ester of pregnenolone. A closely related steroid is dehydroepiandrosterone sulfate (DHEA-S), which is the C3β sulfate ester of dehydroepiandrosterone (DHEA).
A neurosteroidogenesis inhibitor is a drug that inhibits the production of endogenous neurosteroids.Neurosteroids include the excitatory neurosteroids pregnenolone sulfate, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEA-S), and the inhibitory neurosteroids allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), and 3α-androstanediol, among others.

Steroidogenesis inhibitors are analogous in effect and use to antigonadotropins (which specifically inhibit gonadal sex steroid production), but work via a different mechanism of action; whereas antigonadotropins suppress gonadal production of sex steroids by effecting negative feedback on and thereby suppressing the hypothalamic–pituitary ...
3β-Methoxypregnenolone (MAP-4343), or pregnenolone 3β-methyl ether, is a synthetic neuroactive steroid and pregnenolone derivative that interacts with microtubule-associated protein 2 (MAP2) in a similar manner to pregnenolone and is under development for potential clinical use for indications such as the treatment of brain and spinal cord ...
In addition to oral progesterone, oral pregnenolone has also been found to act as a prodrug of allopregnanolone, [65] [66] [67] though also of pregnenolone sulfate. [ 68 ] In animal models of traumatic brain injury , allopregnanolone has been shown to reduce inflammation by attenuating the production of proinflammatory cytokines (IL-1β and TNF ...
Pregnenolone (P5), or pregn-5-en-3β-ol-20-one, is an endogenous steroid and precursor/metabolic intermediate in the biosynthesis of most of the steroid hormones, including the progestogens, androgens, estrogens, glucocorticoids, and mineralocorticoids. [1]
Perampanel is used in addition to other drugs to treat partial seizures and generalized tonic-clonic seizures for people older than twelve years. [8]A 2016 review found it effective for both indications but due to the newness of the drug was unable to describe its optimal role in the treatment of epilepsy relative to other drugs. [10]
