Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/19616537

NT-702 (parogrelil hydrochloride) is a novel phosphodiesterase 3 (PDE) inhibitor, and being developed for the treatment of intermittent claudication (IC) in patients with peripheral arterial disease. In Japan, Phase 2 studies are being conducted for intermittent claudication caused by arteriosclerosis obliterans, intermittent claudication caused by spinal canal stenosis, and asthma. In the USA, a Phase 2 study for intermittent claudication caused by arteriosclerosis obliterans has been successfully completed. Also was shown, that NT-702 has an anti-inflammatory effect as well as a bronchodilating effect and might be useful as a novel potent therapeutic agent with both a bronchodilating and an anti-inflammatory effect.

Sample Use Guides

4 mg and/or 8 mg PAROGRELIL taken twice a day for 24 weeks
Route of Administration: Oral
Was investigated the effects of NT-702 (PAROGRELIL) on arterioles isolated from rabbit lumbar spinal cords. NT-702 caused a dose-dependent dilation of the isolated spinal arterioles. The disruption of endothelium produced a significant reduction of higher concentrations(10(-7) and 10(-6) M), but not lower concentrations (less than 10(-8) M), of NT-702-induced vasodilation. The NT-702-induced vasodilation of the arterioles with endothelium was not affected by pretreatment with an inhibitor of nitric oxide, cyclooxygenase, or cytochrome P-450 monooxygenase. In contrast, catalase reduced significantly the higher concentrations of NT-702-induced vasodilation only.
