Dihydrodeoxycorticosterone (abbreviated as DHDOC; 21-hydroxy-5α-pregnan-20-one) is an endogenous progestogen and neurosteroid.[1] It is synthesized from the adrenal hormone deoxycorticosterone (DOC) by the enzyme 5α-reductase type I.[1] DHDOC is an agonist of the progesterone receptor, as well as a positive allosteric modulator of the GABAA receptor, and is known to have anticonvulsant effects.[1][2]
