ICI-192605

ICI-192605 is an investigational **small-molecule thromboxane A2 receptor antagonist** developed as a selective blocker of the thromboxane prostanoid receptor. In the cited pharmacology literature it is used to inhibit responses to thromboxane mimetics and isoprostanes, including airway smooth muscle contraction, plasma exudation in guinea pig airways, pulmonary vascular responses, and radial artery vasoconstriction, supporting its identification as a TP receptor antagonist rather than a marketed therapeutic. The available context does not establish an approved commercial product, manufacturer, dosage form, or late-stage clinical development program, and the compound appears to have been used primarily as a research or preclinical pharmacology tool.
