Mononitrate ya Isosorbide

Isosorbide Mononitrate is a heart medication that helps people who suffer from angina, heart failure and oesophageal spasms. The medication's high bioavailability makes it a top choice for doctors—more than 95% of the drug reaches the bloodstream after intake. The medicine works quickly with a 5-hour half-life, and the kidneys remove the majority of it from the body.

Patients will find everything they need to know about isosorbide mononitrate tablets in this article. The content covers what it all means, dosing guidelines, and the medication's effects on the body. 

What is Isosorbide Mononitrate?

This medicine acts as an active metabolite of isosorbide dinitrate. It works as a prodrug and releases nitric oxide that intervenes in its therapeutic action. The drug lasts longer than nitroglycerin because the body absorbs and metabolises it slowly. The medication helps blood vessels relax, especially veins, which reduces the heart's workload.

Isosorbide Mononitrate Uses

The main goal of this medication is to prevent and treat angina pectoris caused by coronary artery disease. The drug helps manage heart failure and oesophageal spasms. However, it doesn't work fast enough to stop an acute anginal attack that has already started.

How and When to Use Isosorbide Mononitrate Tablets

Your doctor's prescription determines how you should take this medicine. Standard tablets usually need two doses daily, spaced seven hours apart. Extended-release formulations need just one dose daily, usually in the morning. You should swallow extended-release tablets whole with water—never crush or chew them.

How Isosorbide Mononitrate Tablets Work
