Introduction
Nitroglycerin tablets are a commonly used medication for the treatment of angina pectoris. Their main therapeutic effects and functions include anti-myocardial ischemia, lowering blood pressure, improving cardiac function, preventing angina attacks, and preventing myocardial infarction. If needed, they should be used under the guidance of a physician. However, attention should be paid to the side effects of nitroglycerin tablets, such as headache, hypotension, and dizziness.
Nitroglycerin tablets are commonly used medications for treating angina pectoris. Their main therapeutic effects and functions include anti-myocardial ischemia, lowering blood pressure, improving cardiac function, preventing angina attacks, and preventing myocardial infarction. Usage should be under the guidance of a physician. Detailed explanations are as follows:
1. Anti-Myocardial Ischemia
Nitroglycerin tablets have an anti-myocardial ischemia effect, protecting myocardial cells from ischemic damage. They play a certain therapeutic role in treating ischemic heart diseases such as coronary artery disease and angina pectoris.
2. Lowering Blood Pressure
Nitroglycerin tablets dilate blood vessels, reduce vascular resistance, and thereby lower blood pressure. They can be beneficial for patients with hypertension or heart conditions requiring blood pressure control.
3. Improving Cardiac Function
By dilating blood vessels, nitroglycerin tablets can reduce the workload on the heart and improve cardiac function. For patients with heart failure, this helps alleviate symptoms and improve quality of life.
4. Preventing Angina Attacks
Through continuous vasodilation and maintaining adequate blood supply to the heart, regular use of nitroglycerin tablets can reduce the cardiac workload during daily activities and decrease the frequency of angina attacks.
5. Preventing Myocardial Infarction
Nitroglycerin tablets dilate the coronary arteries and peripheral blood vessels, reducing both preload and afterload on the heart, decreasing myocardial oxygen consumption, and helping to prevent myocardial infarction. They offer a certain degree of protection for patients with coronary artery disease.
However, attention should be paid to the side effects of nitroglycerin tablets, such as headache, hypotension, and dizziness. Patients with severe hypotension, glaucoma, increased intracranial pressure, or similar conditions should not take this medication.
