Adenosine Injection – Onco India International

Overview

Adenosine Injection, manufactured by Onco India International, is a cardiac medicine primarily used for the treatment, control, prevention, and improvement of heart rhythm disorders. It is particularly effective in patients with Paroxysmal Supraventricular Tachycardia (PSVT) and is also used during a heart stress test to evaluate coronary artery function.

The injection contains Adenosine (3 mg) as its active ingredient. It works by relaxing blood vessels, improving blood flow, and helping restore a normal heart rhythm.

Uses of Adenosine Injection

Adenosine Injection is indicated in:

• Paroxysmal Supraventricular Tachycardia (PSVT) – rapid heart rate originating above the ventricles

• Diagnostic Heart Stress Testing – used in place of exercise stress tests to study coronary circulation

• Restoration of Normal Heart Rhythm – in cases of abnormal conduction in the atrioventricular (AV) node

Mechanism of Action

• Relaxes blood vessels to increase blood flow to the heart

• Slows down conduction through the AV node

• Helps restore normal sinus rhythm in patients with rapid, irregular heartbeats

Composition

• Active Ingredient: Adenosine 3 mg (per injection)
