Nitroglycerin Ointment
Nitro-Bid is a topical nitrate medication used to treat and prevent angina (chest pain) by improving blood flow to the heart muscle. It contains nitroglycerin that is absorbed through the skin and works by dilating blood vessels, reducing the heart's workload and oxygen demand. This medication is typically prescribed for patients with coronary artery disease who experience recurrent chest pain.

Nitro-Bid is primarily used for the treatment and prevention of angina pectoris (chest pain caused by reduced blood flow to the heart). It may also be used in certain cases for conditions involving anal fissures when prescribed off-label.
Nitro-Bid contains nitroglycerin, which is converted to nitric oxide in the body. This relaxes and widens blood vessels, primarily veins, reducing the amount of blood returning to the heart and decreasing cardiac workload and oxygen demand. The improved oxygen supply to the heart muscle helps relieve anginal symptoms.
Nitro-Bid should not be used with erectile dysfunction medications (such as sildenafil or tadalafil) due to risk of severe hypotension. Common side effects may include headache, dizziness, and flushing. Tolerance may develop with continuous use, requiring a nitrate-free interval. Patients should follow application instructions carefully to avoid overdose and inform their doctor of all medications they are taking.
