Application

Ozagrel hydrochloride hydrate has been used as a thromboxane synthase inhibitor:
  • in high cholesterol-diet rats (HC) to test its effect on arteriolar constriction
  • to pre-treat mice to test its effect on lipopolysaccharide (LPS)-induced behavioral changes
  • to test its effect on arteriolar vasoconstriction in hyperglycemic mice

Biochem/physiol Actions

Ozagrel is useful in treating lacunar and thrombotic stroke. It blocks vasoconstriction and platelet aggregation. Ozagrel aids in improving the prostacyclin (PGI2)/ thromboxane A2 (TXA2) in the acute phase of cerebral ischemia. It improves endothelial dysfunction in L-methionine-induced hyperhomocysteinemia (HHcy)-induced vascular cognitive impairment and dementia (VCID).
Ozagrel is a selective thromboxane A2 synthase (TXA2) inhibitor.

This study addresses the role of venule-derived mediators in the arteriolar constriction that accompanies hypercholesterolemia. Constriction was assessed by measuring the tone of small arterioles closely paired with venules in the mesentery of normal cholesterol rats (NC), high cholesterol rats

Rho kinase (ROCK), one of the serine/threonine kinases, is involved in pathologic conditions, and its activation causes neuronal cell death. Fasudil, a selective ROCK inhibitor, has been reported to cause increased cerebral blood flow (CBF) in the ischemic brain and

Reductions in retinal blood flow are observed early in diabetes. Venules may influence arteriolar constriction and flow; therefore, we hypothesized that diabetes would induce the constriction of arterioles that are in close proximity to venules, with the constriction mediated by

Sub-analysis of the fasudil post-marketing surveillance study compared the safety and efficacy of fasudil plus ozagrel to fasudil only. A total of 3690 patients received fasudil and 1138 received fasudil plus ozagrel between 1995 and 2000. The occurrence of adverse

Retinal blood flow decreases early in the progression of diabetic retinopathy; however, the mediators and mechanisms responsible for this decrease have yet to be determined. In this study, diabetes was induced by streptozotocin in rats, and retinal blood flow was
