[Effect of imipramine and ftoracizin on platelet aggregation and smooth muscle contraction of the ureter]. / Vliianie imipramina i ftoratsizina na agregatsiiu trombotsitov i sokratimost' gladkoi myshtsy mochetochnika.

The influence of the tricyclic antidepressants imipramine and ftoracizin on platelet aggregation and smooth muscle contractility was investigated in comparison with action of known smooth muscle relaxant and platelet aggregation inhibitor, papaverine. It has been shown that the tricyclic antidepressants possess potent spasmolytic activity but unlike papaverine have no effect on platelet aggregation. The biochemical mechanisms of the non-specific action of tricyclic antidepressants as well as some other structurally related-drugs are discussed.
