[Fibrinolytic complexes of low-molecular heparin and acetylsalicylic acid].

Complexes of low-molecular heparin with acetylsalicilic acid was formed in vitro when the weight ratio of components was 1:1, 1:5 and 5:1, respectively. All the complexes possessed fibrinolytic and anticoagulating activities. The complex possessed the highest activity when the ratio of heparin to acetylsalicilic acid was 5:1. This complex at a dose 1 mg/200 g of rat weight had the largest thrombolytic effect on the experimental fresh thrombus.
