Nig 5mg Injection belongs to the class of anti-anginal medication, primarily used for treating angina pectoris and myocardial infarction. Nig 5mg Injection can also use to control intraoperative blood pressure. Angina occurs when the heart does not get a sufficient amount of oxygen. A heart attack (myocardial infarction or MI) is a critical medical emergency in which the blood supply to the heart is suddenly cut off.

Nig 5mg Injection contains nitroglycerin, a natural vasodilator that works by relaxing the blood vessels (veins and arteries). This boosts the blood supply to your heart, allowing more oxygen to reach your heart muscles and reducing chest pain. Thus, it prevents and treats various heart conditions.

Nig 5mg Injection is administered by a healthcare professional; do not self-administer. Sometimes, you may experience headaches, hypotension, tachycardia (fast heart rate), dyspnea (shortness of breath), dizziness, light-headedness, and blurred vision as side effects. Most of these side effects are temporary, do not require medical attention, and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Inform your doctor if you are allergic or hypersensitive to any component present in Nig 5mg Injection. If you are pregnant, suspect you are pregnant, plan to have a baby, or if you are breastfeeding, inform your doctor before receiving this medicine; your doctor will prescribe Nig 5mg Injection only if the benefits outweigh the risk. Avoiding alcohol is recommended to rule out any possibility of side effects like dizziness or fainting. It should not be given to children less than 18 years of age. Before taking the Nig 5mg Injection, inform your doctor about your medical history and ongoing medications to rule out any potential adverse effects or interactions.

Nig 5mg Injection contains nitroglycerin, a natural vasodilator primarily used to treat angina pectoris and myocardial infarction. It can also help to control intraoperative hypertension. Nig 5mg Injection works by relaxing the muscles surrounding blood vessels, making the heart's job easier.

Angina pectoris: It is a kind of chest pain caused due to decreased blood flow to the heart, which means insufficient oxygen supply to the heart muscle. The chest pain is often triggered by emotional stress or physical activity. Angina is a symptom of coronary artery disease. The symptoms of angina include dizziness, shortness of breath, nausea, tiredness, anxiety or excessive sweating. The risk factors for angina include smoking, diabetes, overweight, high blood pressure, high cholesterol, not exercising, or a history of heart disease.

Myocardial infarction/Heart attack: Myocardial infarction occurs when a blood clot blocks the blood flow to the heart. This blockage of arteries is often an accumulation of fat, cholesterol and other substances, which form plaque in the arteries that feed the heart (coronary arteries). Heart attack signs include chest pain, upper body pain, sweating, nausea, fatigue, and trouble breathing.

Perioperative hypertension: Perioperative hypertension is frequently associated with one of the following events: during anaesthesia induction; intraoperatively as a result of acute pain-induced sympathetic stimulation leading to vasoconstriction
