Nitrong (Glyceryl Trinitrate)

Glyceryl trinitrate is converted to nitric oxide after absorption. Nitric oxide activates guanylate cyclase, raising cyclic GMP levels in vascular smooth muscle, which leads to relaxation of veins and arteries. This vasodilation reduces cardiac preload and afterload, lowering myocardial oxygen demand and alleviating angina.

The prescribed dose of Nitrong is determined by the treating physician based on the patient’s clinical condition, severity of symptoms, and response to therapy. The prescriber selects the appropriate patch strength and duration of wear, and patients should follow the specific instructions provided on the prescription label.

The safety of Nitrong in pregnancy and lactation has not been definitively established. It should only be used if the potential benefit justifies the potential risk to the fetus or infant, and this decision must be made by a qualified healthcare professional after a thorough risk‑benefit assessment.

Nitrong belongs to the organic nitrate class, which provides rapid vasodilation through nitric‑oxide release. Compared with beta‑blockers or calcium‑channel blockers, nitrates act directly on vascular smooth muscle and are particularly effective for immediate relief of angina. However, tolerance can develop with continuous use, so drug‑free intervals are often recommended.

Nitrong patches should be stored at room temperature, below 25 °C, in their original sealed packaging. Keep them away from moisture, direct sunlight, and sources of heat. Do not expose the patches to temperatures above the recommended range, as this may affect drug stability and adhesion.

Nitrong is a transdermal patch applied to clean, dry, and hair‑free skin on the upper arm, chest, or back. The patch is pressed firmly for several seconds to ensure good contact, and it is typically worn for a prescribed period (often 12–24 hours) before being removed and replaced with a fresh patch according to the dosing schedule.

The most serious risks include severe hypotension, syncope, and rare allergic reactions such as rash or breathing difficulty. Patients should be monitored for sudden drops in blood pressure, especially when combined with other vasodilators, and any signs of an allergic response require immediate medical attention.

Nitrong is contraindicated in patients with known hypersensitivity to glyceryl trinitrate or other organic nitrates, those who have taken phosphodiesterase‑5 inhibitors within the past 24 hours, and individuals with severe anemia or uncontrolled hypotension. Clinicians should also exercise caution in patients with significant hepatic impairment.
