Proroxan (INN; also known as pyrroxane and pirroksan) is a pharmaceutical drug used as an antihypertensive and in the treatment of Ménière's disease, motion sickness, and allergic dermatitis.

[1][2] Proroxan is a non-selective alpha-blocker (α-adrenoreceptor antagonist).

[1] Proroxan was developed in the 1970s at the Institute of Toxicology of the USSR Ministry of Health[3] and today is primarily used in Russia.

Though originally developed as an antihypertensive, its use can lead to a decrease in alcohol and drug consumption.

Currently proroxan is used almost exclusively in psychiatry, narcology, and neurology.
