Nitroglycerin is a drug that dilates blood vessels and reduces the load on the heart. It is often used to treat angina. It reduces the symptoms of cardiac ischemia by relaxing vascular smooth muscle, increasing the diameter of the vascular lumen, reducing blood pressure and cardiac load. Nitroglycerin is mainly used for the relief of acute angina pectoris attacks and can also be used for preventive treatment. Patients usually need to place nitroglycerin lozenges under their tongue or in their mouth and wait for the tablet to completely dissolve before swallowing. When using nitroglycerin, follow your doctor's advice and do not change the dosage or frequency. Possible side effects include headache, low blood pressure, and dizziness. If serious adverse reactions occur, such as persistent headache or fainting, seek medical attention immediately. Ask your doctor for more information about nitroglycerin.
How to use: Place glyceryl trinitrate medication under the tongue and allow it to be quickly absorbed in the mouth. Typically, it is not necessary to take it with food, but use with alcoholic beverages should be avoided. You should avoid heavy activities or operating machinery while using the drug.
Dosing Guidelines: For adults, a starting dose of 0.4 mg to 0.8 mg may be repeated every 5 minutes up to 3 times. Dose adjustments should be made based on patient response, but the total dose should not exceed 3 mg. For children, lower doses are recommended and should be determined by a physician on a case-by-case basis. Be sure to follow your doctor's instructions when using your medications and seek medical attention if necessary.
GLYCERYL TRINITRATE is a drug commonly used to treat heart disease, but it has some side effects to be aware of. Some patients may experience dizziness, headache, nausea and hypotension after taking it. Some people may experience dry mouth, facial flushing, or heart palpitations. Long-term use may lead to drug resistance, requiring dose adjustment. If you experience serious side effects such as difficulty breathing, chest pain, or abnormal heartbeat, seek medical attention immediately. When using GLYCERYL TRINITRATE, remember to take it according to your doctor's recommendations and avoid increasing or decreasing the dosage on your own.
