Ntg 5mg Injection

Ntg is prescribed to prevent attacks of heart-related chest pain (angina) in patients with coronary artery disease. In this disease, the blood vessels (coronary arteries) which supply blood to the heart become narrow because of which the heart has to work harder to get enough oxygen. Ntg prevents angina by relaxing the blood vessels so that the heart does not have to work very hard. Also, relaxation of coronary arteries increases the oxygen supply to the heart.

Yes, excessive use of Ntg may cause tolerance which means that Ntg may lose its effectiveness on you. Therefore, doctors usually prescribe the smallest dose required for effective relief of acute angina attacks. Also, it is usually prescribed in morning and afternoon doses to give nitrate-free interval. Take it strictly as per the dosing interval prescribed by your doctor to prevent tolerance and maintain the effectiveness of Ntg.

Ntg slightly decreases the blood pressure by relaxing the blood vessels, but is not recommended for the treatment of high blood pressure. The drop in blood pressure may cause lightheadedness, especially when changing your position suddenly. You should avoid sudden change in your position, for eg, get up slowly if you are sitting or lying down, to minimise this side effect.

Excess Ntg may result in low blood pressure, sweating, nausea, vomiting, headache, weak and fast pulse. It may also cause weakness, lightheadedness on standing and the patient might even faint. The patient will require emergency medical treatment in such a case.
