A variety of medications may be used in the treatment of various medical and surgical conditions. Some drugs may cause asthma attacks or aggravation, so asthma patients and their families should be aware of the types of these drugs and treatment measures. Aspirin is a widely used antipyretic and analgesic drug, used in the treatment of various kinds of antipyretic and analgesic, and many middle-aged and elderly patients use small doses of aspirin to prevent blood clots. However, aspirin has the potential to cause severe asthma attacks and must be contraindicated in asthma patients with a history of previous aspirin allergy. Similarly, “aminopyrine, anandamide, phentermine, finasteride, indomethacin (anti-inflammatory pain), ibuprofen, diclofenac, Inflammatory Pain Relief, and cold medicines containing these ingredients” should also be used with caution. In the event of an asthma attack triggered by these drugs, use “intravenous glucocorticoid hormones” and “montelukast” as soon as possible, and they will usually be relieved quickly. It is important to note that not all asthma patients should not use these drugs because they are widely used in daily life. If you have used it many times without any obvious discomfort, you can continue to use it; if you have not used such drugs in the past, you need to consider carefully and try to use other drugs instead. 2, to the “heart, betalac” on behalf of the cardiovascular drugs These drugs through the blocking of the heart muscle and blood vessels on the β1-receptors and play a lowering of blood pressure and heart rate therapeutic effect, widely used in the treatment of hypertension, coronary heart disease. However, these drugs also block β2-receptors on bronchial smooth muscle, which can trigger asthma. The mechanism of the adverse effects of these drugs on asthma is not allergy and should be prohibited in all asthma patients. But what about the occasion when an asthmatic patient has a concomitant rapid heart rate and increased blood pressure, and this type of beta-blocker must be used in the treatment? The answer is to use the more specific “Bisoprolol (Convoy, Bosu)”, which can specifically block the β1-receptor, but has little effect on the β2-receptor, which can play a cardiovascular therapeutic role while avoiding asthma-inducing side effects, and has a better safety. 3.Iodine contrast agent: mainly related to iodine allergy Before performing certain imaging examinations, it is necessary to use contrast agent, asthma patients should ask the doctor whether the contrast agent contains “iodine”, iodine-containing contrast agent needs to be “tested for sensitivity” to pick up the test, but it is good that most of the large hospitals currently The good news is that most of the contrast agents used in large hospitals, such as “Uvexan”, do not contain iodine, which has significantly improved safety. 4, some food additives Many foods, beverages and pharmaceutical preparations are colored with yellow dye – tartar yellow, which can cause measles, angioedema of the mouth and lips and even bronchial asthma. In addition, the preservation preservatives used in alcohol or juice drinks and pharmaceutical preparations, such as bicarbonate of nitrite, can also cause bronchial asthma. Asthma patients should carefully read the ingredients in the instructions before using beverages and packaged foods to avoid consumption.
