title: Human platelet aggregation tests in vitro. Effects of dilazep.
abstract: The effect of 1,4-bis-[3(3,4,,5-trimethoxybenzoyl-oxy)-propyl]-perhydro-1,4-diazepine (dilazep, Cormelian), a coronaroactive drug, was studied by various tests of hemostasis in vitro on human plasma. The antiplatelet action of the drug was clearly demonstrated: it inhibited, in appropriate concentrations, ADP, adrenaline and collagen induced aggregation platelet factor 3 (PF3) availability and clot retraction induced by ADP-reptilase. Conversely, coagulation tests as well as the lysis time of diluted whole blood were unaffected by the drug.
