Pregnenolone succinate (USAN; brand names Panzalone, Formula 405; also known as pregnenolone hemisuccinate or pregn-5-en-3β-ol-20-one 3β-(hydrogen succinate)) is a synthetic pregnane steroid and an ester of pregnenolone which is described as a glucocorticoid and anti-inflammatory drug and has been patented and marketed as a topical medication in the form of a cream for the treatment of allergic, pruritic, and inflammatory dermatitis.[1][2][3] It has also been described as a non-hormonal sterol, having neurosteroid activity, and forming a progesterone analogue via dehydrogenation.[4]

In addition to its glucocorticoid effects, pregnenolone succinate has been found to act as a negative allosteric modulator of the GABA_A receptor and a positive allosteric modulator of the NMDA receptor similarly to pregnenolone sulfate.[5][6][7][8]
