Nitroglycerin and herbal quick-acting heart pills, which are used to relieve angina, are referred to as “heart pills”. If you do not take them properly, they will not be able to play a role in first aid. The experts have compiled a 24-word recipe for those who want to take heart-saving drugs to remember and master them: the drug should be “new”, prevent “addiction”, chew first and then contain, pay attention to the posture, the matter is not more than three, the drug does not leave the body The medicine should be “new”. Drugs to “new”: these drugs are valid for one year, but patients should usually pay attention to whether the drug has become soft, sticky, discolored, broken phenomenon, found that the deterioration should be updated immediately to avoid emergency and failure and affect the treatment. Prevent “addiction”: often take this type of drugs may also be “addicted”. To prevent “addiction” can be two kinds of first aid drugs used alternately. Chew first and then eat: Most people take it under the tongue according to the instructions, and the effect is good, but if you can chew it first and then press it under the tongue during an angina attack, the effect is better. Because chewing is easier to dissolve and sublingual mucosa absorption, can reach the heart quickly in high concentration, the effect is faster. Posture: When taking this drug, you should take a sitting position. Because of the standing position, the head position is higher, often due to peripheral vasodilation and lower blood pressure, causing fainting. Lying down is also inappropriate, because the heart position is low, and a lot of blood flow back to the heart, resulting in a sudden increase in the amount of blood stored in the heart, increasing the burden on the heart. But three: in the case of effective drugs, usually after a few minutes of medication angina should be relieved. If it still does not work, you should take it again after 5-10 minutes. Repeat this 2-3 times, if it is still ineffective, you should consider the possibility of myocardial infarction or other diseases, and should immediately go to the hospital for treatment. Therefore, the motto of “no more than three” should be the motto of those who take “heart saving drugs”. The medication should be carried with you and placed in a fixed, easy-to-fetch garment bag. When changing clothes, don’t forget to transfer the “heart medicine” at the same time; when sleeping at night, you should put the “heart medicine” on the side of the pillow where you can easily get it, so that you can reach it when you need it urgently, so that the medicine is always on your body.
