GTN Spray

Product Overview

GTN Spray is a nitrate-based medication containing Glyceryl Trinitrate as its active component. It is primarily prescribed for treating angina pectoris – chest pain resulting from insufficient blood supply to the heart muscle. The medication functions by dilating blood vessels, which enhances cardiac blood circulation and decreases the heart’s workload.

Therapeutic Applications

This medication serves two main purposes: providing immediate relief during acute angina episodes and preventing angina attacks triggered by physical activity or emotional stress. It’s also employed for managing chronic stable angina and as preventive therapy before engaging in activities likely to induce angina.

Administration Guidelines

For proper use:
1. Remove the protective cap and shake the container vigorously
2. Hold the bottle upright near your mouth
3. Direct the nozzle beneath the tongue
4. Depress the actuator to release the spray (avoid inhaling during administration)
5. May repeat every 5 minutes if needed, not exceeding three doses unless medically advised

Mechanism of Action

The active compound Glyceryl Trinitrate acts as a potent vasodilator, specifically targeting vascular smooth muscles. This pharmacological action causes significant dilation of both venous and arterial vessels, resulting in:
• Reduced vascular resistance
• Enhanced oxygenated blood delivery to cardiac tissue
• Subsequent relief from angina symptoms

Dosing Protocol

Standard dosing involves:
• Initial dose: 1-2 sublingual sprays for symptom relief
• Maximum dose: 3 sprays within 15 minutes
• Medical consultation required if symptoms persist beyond maximum dosage
Individual dosing may vary based on symptom severity and therapeutic response.
