isosorbide dinitrate profile

Isosorbide dinitrate is a nitrate ester that is used as a vasodilator to treat angina pectoris. It is synthesized by the nitration of isosorbide. Isosorbide dinitrate acts primarily by relaxing vascular smooth muscle, leading to vasodilation and a decrease in preload and afterload. It is also used to prevent migraine headaches. Isosorbide dinitrate is studied to understand its effects on blood vessels, heart function, and pain management. It is also being investigated for its potential use in treating other conditions, such as pulmonary hypertension and peripheral artery disease.'

Isosorbide Dinitrate: A vasodilator used in the treatment of ANGINA PECTORIS. Its actions are similar to NITROGLYCERIN but with a slower onset of action. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Research Excerpts

Overview

Isosorbide dinitrate is a vasodilator with effects on both arteries and veins and induces opening of vascular layers. It is an effective treatment for anal fissure and is significantly better than placebo.

Effects

Isosorbide dinitrate (ISDN) has an inhibitory effect on platelet aggregation through the generation of nitric oxide (NO)

Isosorbide dinitrate (ISDN) has been used in the treatment of ischaemic cardiovascular diseases for many years. It has a cytoprotective activity on the gastric mucosa of rats submitted to ketoprofen action.

Treatment

Isosorbide dinitrate treatment provided 64.6 and 67.6% protection for motor and sensory nerves, respectively (P < 0.01) When treatment was stopped there was a significant increase in the total number and duration of painless episodes of myocardial ischaemia.

Pharmacokinetics

To make a physiologically-based pharmacokinetic model of isosorbide dinitrate (ISDN), the author infused ISDN at 1, 10, 30 micrograms. In a randomized, open-label, three-way crossover trial in 24 healthy men, ISDN was given 40 mg every 6 hours.
