Description

Dazmegrel [UK 38485] is a thromboxane synthetase inhibitor which was undergoing development in the treatment of thrombosis, ischaemic heart disease, arrhythmias and asthma. Pfizer were conducting phase II studies in Denmark and the UK, phase I studies in Germany and Italy, and preclinical studies in France. Later this research was discontinued.

Sample Use Guides

In Vivo Use Guide
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.
Route of Administration: Oral
In Vitro Use Guide
Pretreatment of lung strips for 60 min with the thromboxane synthetase inhibitor, dazmegrel (10 uM),relaxed the spontaneous tone of the tissues, abolished the LTD4 (200 nM)-stimulated release of TXB2 and significantly enhanced (~two fold) the elaboration of 6-keto-PGF1alpha.
