Fibrinolytic activity under the effect of oral contraceptives

ABSTRACT

Twenty women were given Anovlar 1 tablets cyclically for six months, and the fibrinolytic activity of their plasma was studied by the euglobulin clot lysis time. Pre-intake study was done for 30 women, and for another group of long-term users of Anovlar and Anovlar 1 tablets for 2-10 years. There was a significant shortening in the euglobulin lysis time in the two groups of pill users. This enhanced fibrinolytic activity counter balances the increase in the blood coagulation and thus preventing the occurrence of intravascular thrombosis
