Laropiprant (LRPT) is being developed in combination with Merck's extended-release niacin (ERN) formulation for the treatment of dyslipidemia. LRPT, an antagonist of the prostaglandin PGD₂ receptor DP1, reduces flushing symptoms associated with ERN. LRPT also has affinity for the thromboxane A₂ receptor TP (approximately 190-fold less potent at TP compared with DP1). Aspirin and clopidogrel are two frequently used anti-clotting agents with different mechanisms of action. Since LRPT may potentially be co-administered with either one of these agents, these studies were conducted to assess the effects of steady-state LRPT on the antiplatelet activity of steady-state clopidogrel or aspirin. Bleeding time …

The drug discovery process has become increasingly complex in comparison to early efforts particularly those involving diseases or conditions that affect large numbers of the human population. It is difficult to point directly to one factor leading evolution of the process but the definition of a mechanism of pharmacological action for a drug lead has noticeably become a higher priority. This evolution has helped diminish the stigma of natural products and compound supply issues. The issue of compound supply has also been addressed to some extent with the emergence of recombinant technologies and new synthetic methodology. With approximately 60 years …
