The principle of the function of nitroglycerin can expand coronary arteries and venous blood vessels, reduce the cause of angina pectoris, reduce the oxygen consumption of myocardium, increase myocardial blood supply, and achieve the effect of analgesic relieving analgesic effect. Essence
Take nitroglycerin tablets and take medicine to get the method, otherwise the expected results will not be achieved. You must pay attention to the following points:
1. It should be served under the tongue. Do not swallow because the capillaries under the tongue are rich in blood. The drug quickly absorbs the blood, and an analgesic effect occurs in 1-2 minutes. And swallowing slowly and poor effect.
2. The use of sitting or half -lying posture of nitroglycerin on cerebral blood vessels is obvious. Immediately after taking the medicine, the appearance of redness and headache appeared. When standing, “upright hypotension” occurred and was prone to fainting. Elderly patients or patients who take medicine for the first time have dizziness and headache after taking the medicine. As long as they are resting on flat or symptomatic treatment, they will return to normal quickly without any hindrance. With the extension of the medication time, this effect gradually reduces and even disappears.
3. When choosing the most ideal amount of dosage, when you start taking nitroglycerin tablets, the dose should not be too large, otherwise there will be side effects. Generally, it is better to take a half or a piece (0.15-0.30 mg) each time. How much medication is determined according to the condition, it is best to find a dose that is suitable for each patient to achieve the curative effect and make the side effects small. If the amount of medication is increased, 3-5 tablets are served in the short term, indicating that the condition changes, and you need to go to the doctor in time.
4. Selecting nitroglycerin dosage formation can be divided into fast, medium -long and long -acting dosage forms. When angina pectoris attacks, first aid generally uses fast -acting classes such as nitroglycerin tablets. If the angina pectoris occurs repeatedly, the medium -long and long -acting agent can be taken at the same time at the same time to prevent the attack again. Medium-long and long-term drugs are commonly used in heartache, long-acting nitroglycerin, and the general medicinal effect can last 4-8 hours.
5, nitroglycerin tablets and other medicines are accompanied by angina pectoris with fast heart rate, can be peaceful at the same time; those with high blood pressure with angina pectoris can be set with heartache. Nitrate glycerin can also be combined with albid fixation and sulfolzolone to enhance the efficacy, and restraint and side effects.
6. Patients who can prevent sexual use for prediction for a certain force or activity to produce angina pectoris can be used before force. For example, after meals, angina pectoris can be prone to occur during stool, and you can first contain nitroglycerin before meals to stop the attack.
7. Precautions In order to maintain the efficacy of nitroglycerin tablets, this medicine should be placed in a closed color bottle of a closed light, and pay attention to the validity period of the drug to replace the pills close to the failure period in time. Patients or elderly people with a history of angina pectoris should be carried with them and placed in a convenient first aid box.

In addition, nitroglycerin can increase brain pressure and intraocular pressure, and patients with glaucoma and cerebral hemorrhage should be used with caution. The validity period of nitroglycerin is about 1 year. Patients should pay attention to the effective period of drugs and replace them in time.
At present, nitroglycerin has a membrane agent and oral spray. The external use of the membrane agent is on the left chest, and the drug is uniformly absorbed through the skin, and the role of anti -angina pectoris is continuously played within 24 hours. The oral spray is welcomed by patients due to small dosage, faster absorption, and small side effects. The above two dosage types are more expensive, which is not conducive to promotion and use.
