[EN] Anti-thrombotic compositions include anti-thrombotic steroids together with potentiators thereof (e.g. heparin or cyclodextrin) or with a thrombolytic substance such as tissue plasminogen activator. Therapy, in which thrombosis in a mammal at risk is prevented or treated, comprises administering an effective amount of a steroid possessing anti-thrombotic activity or a pharmaceutically acceptable salt thereof.

Certain 3 alpha-hydroxy steroids have recently been shown to bind to the gamma-aminobutyric acid (GABA) receptor gated chloride ion channel with high affinity and to potentiate the inhibitory effects of GABA when measured both in vitro and in vivo. In the present study, a series of natural and synthetic 3 alpha-hydroxy steroids were tested for their ability to potentiate GABA-receptor-mediated chloride
