background: nitric oxide (no), a major chemical form of endothelium-derived relaxing factor and an important regulator of vascular tone, is released by endothelial cells. the role of no is not restricted to the vascular system, and it participates in the regulation of renal hemodynamics and renal excretory function. there are increasing evidences indicating that the elevated levels of no play a...

The case of a patient with repeated attacks of collapse induced by sublingual isosorbide dinitrate is reported. The patient was an 81 year-old female who was admitted to Yura Hospital because of attacks of precordial pain. Several minutes after the sublingual administration of isosorbide dinitrate (10 mg) for an anginal attack, she developed a sensation of general weakness, and thereafter becau...

DFT calculations combined with experiments unveil the key role of H 2 coverage on Ru/C catalyst in isomerization isosorbide.

Because of the high efficacy of existing nitrates, alternative dosage formulations have been developed rather than new compounds. These new formulations challenge the analyst to develop analytical methods with lower sensitivity and higher precision. Isosorbide dinitrate is analysed in the presence of its major metabolites isosorbide 2-mononitrate and isosorbide 5-mononitrate. The present method...

The aortic pulse wave contour in isolated systolic hypertension often shows a prominent reflection peak, which combines with the incident wave arising from cardiac ejection so as to widen pulse pressure. We investigated the effects of an extended-release nitrate preparation and of 2 angiotensin II (AII) inhibitors (an AII receptor antagonist and an ACE inhibitor) on the aortic pulse wave contou...

A double-blind study of the effects of isosorbide dinitrate, 10 mg given orally four times a day, propranolol, 40 mg four times a day, and the combination of these two drugs was performed on 21 patients with angina pectoris. Each patient received placebo, isosorbide, propranolol, and the combination of the two drugs for 1 month each in a random sequence over 4 months. The number of anginal pain...

Cellulose-derived photocrosslinkable polycarbonates with renewable citronellol pendant chains were synthesised via polycondensation of Triol-citro, a levoglucosenone-based triol monomer, and dimethoxycarbonyl isosorbide.

Isosorbide 5-mononitrate (5-ISMN) is an organic nitrate widely used for its vasodilating properties in the treatment of angina pectoris. In the present study, an efficient, sensitive, robust method was developed for the determination and quantification of isosorbide 5-mononitrate, in human plasma, by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), using photospray ioniza...
