Effects of a selective inhibitor of inducible nitric oxide synthase, ONO-1714, on experimental hemodialysis-related hypotension in renal dysfunctional dogs.

摘要

The effect of a selective inducible nitric oxide synthase inhibitor, ONO-1714 ((1S,5S,6R,7R)-7-chloro-3-imino-5-methyl-2-azabicyclo[4.1.0]heptane hydrochloride), on hemodialysis-related hypotension was investigated using a canine model of renal dysfunction. Renal dysfunction was induced in dogs by complete bilateral ligation of renal arteries. On performing hemodialysis with ultrafiltration, the blood pressure of the renal dysfunction dogs gradually decreased and persisted at reduced levels until completion. ONO-1714 ameliorated the hemodialysis-induced hypotension in the renal dysfunction dogs at a dose that did not influence blood pressure in non-hemodialysis dogs with normal renal function. The above findings indicated that ONO-1714 may elicit beneficial effects on hemodialysis-related hypotension.
