The pharmacokinetics of dazmegrel (UK-38,485), a novel selective thromboxane synthase inhibitor, and its effects on in vivo prostanoid formation were studied in a 2 weeks, multiple dose, placebo controlled, double blind trial in man. The drug was well tolerated. After dazmegrel 50-200 mg p.o. peak plasma levels of 0.7-3 mu/ml were reached within 1 hr. Elimination was of first order with a half life of 0.88 +/- 0.17 hr. Platelet count and bleeding time were unchanged by all regimes of dazmegrel used (100 and 200 mg b.i.d.; 50, 100 and 200 mg t.i.d.). Serum thromboxane (TXB2) was more than 95% suppressed one hour after all doses studied, but 200 mg t.i.d. were needed suppress circadian serum TXB2 profiles more than 90% at all times. Urinary excretion of 2,3-dinor-TXB2 (TXA2-M) fell by over 90%. An increase in the excretion of 2,3-dinor-6-keto-PGF1 alpha (PGI2-M), the major metabolite of prostacyclin, was largely transient and fell short of significance at all times. The ratio of TXA2-M to PGI2-M was lowered from about 5.0 to 0.2 and sustained throughout treatment. Dazmegrel selectively blocks in vivo and ex vivo TXA2 formation. Redirection of endoperoxides from total body TXA2 formation into prostacyclin formation is only minor under basal conditions.
