The circulatory response and plasma concentrations of isosorbide dinitrate (ISDN) were determined in 10 patients with chronic, stable angina after administration of 5 mg of sublingual ISDN during the control stage, after 48 hr of therapy with 15 mg of ISDN orally every 6 hr, and subsequently after a 48 hr period when ISDN was substituted by placebo four times daily. Initially, sublingual ISDN i...

The duration of effects of single oral doses of 15, 30 and 60 mg of isosorbide dinitrate (ISDN) were studied in 12 patients with stable, exercise-induced angina pectoris. The effects of a 120-mg dose were also studied in seven of these 12 patients. The average peak values for plasma ISDN concentration were 6.8, 14.3, 17.5 and 26.0 ng/ml after 15, 30, 60 and 120 mg of ISDN, respectively, and the...

This study describes the relationship between nitroglycerin, isosorbide dinitrate, sodium nitroprusside, and carbonic anhydrase I, as well as the involvement of this carbonic anhydrase I in vasodilation. Two groups of coronary patients and a group of rabbits underwent treatment with the above-mentioned vasodilating drugs. The activity of red blood cell carbonic anhydrase was monitored and deter...

INTRODUCTION Based upon the findings of the African-American Heart Failure Trial, the US Food and Drug Administration approved the fixed-dose combination of isosorbide dinitrate (ISDN) and hydralazine hydrochloride (HYD) (FDC-ISDN/HYD) as a new drug for treatment of heart failure (HF) in self-identified African Americans. According to the FDA, FDC-ISDN/HYD has no therapeutic equivalent. However...

A new N-heterocyclic carbene (NHC)-catalyzed strategy for the regioselective monoesterification of isosorbide (IS) at either endo (5-OH) or exo (2-OH) position is described. Site-selective acylation proceeds under oxidative conditions in presence a quinone oxidant using aldehydes as mild acylating agents. Experimental evidences suggest role stereoelectronic features acyl azolium salt intermedia...

The title compound, C(12)H(18)N(8) (2+)·2NO(3) (-)·2H(2)O, was synthesized unexpectedly from 3-amino-1-methyl-1,4,5,6-tetra-hydro-pyrrolo-[3,4-c]pyrazol-5-ium chloride and cerium(IV) ammonium nitrate. The cation has a crystallographically imposed centre of symmetry. In the crystal, the ions and water mol-ecules are linked via O-H⋯N, N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.
