Modern medicine in China is developing along the road of integration of traditional Chinese and western medicine. In most cases, the combination of traditional Chinese and western medicine can complement each other, enhance the curative effect or reduce adverse reactions. Some Chinese patent medicines also contain western medicine ingredients, which have achieved good curative effect, but the chemical composition of Chinese and western medicines is very different, and their pharmacological effects are different. If we blindly combine traditional Chinese and western medicine and ignore some compatibility taboos, it will be counterproductive, aggravate the condition or cause new diseases, which requires special attention. After getting up one morning, Uncle Zhang showed a bright red blood stain on his white eyeball, which startled him and his family and hurried to the hospital. After carefully examining the medical history and medication history, the doctor said, "Uncle Zhang is suffering from scleral hemorrhage, which is related to taking western medicine aspirin and Chinese medicine Ginkgo biloba at the same time." Modern medicine in China is developing along the road of integration of traditional Chinese and western medicine. In most cases, the combination of traditional Chinese and western medicine can complement each other, enhance the curative effect or reduce adverse reactions. Some Chinese patent medicines also contain western medicine ingredients, which have achieved good results, such as vitamin C Yinqiao tablets, Ganmaoqing capsules and Xiaoke pills. However, there are great differences in chemical composition and pharmacological effects between Chinese and western medicines. If you use it blindly and ignore some compatibility taboos of Chinese and western medicines, it will be counterproductive; It not only reduces the curative effect of drugs, but also may lead to adverse interactions, aggravate the condition or trigger new diseases. For example, taking Ginkgo biloba leaves with acetaminophen, aspirin, warfarin and ergotamine caffeine at the same time will cause hematoma, and taking it with hydrochlorothiazide tablets at the same time will cause blood pressure to rise. Another example is the Chinese patent medicine Jisheng Shenqi Pill, which contains potassium ions. Combined with spironolactone, triamcinolone acetonide and sulfonamides, it can lead to hyperkalemia and arrhythmia. When some Chinese patent medicines and western medicines are taken together, some affect each other's internal processes such as absorption, distribution, metabolism, excretion, etc., some make their efficacy too strong and cause sensitization, some reduce their efficacy and lose their efficacy, and some produce toxicity or increase their original toxic effects, so these Chinese and western medicines should not be taken at the same time. Although most Chinese patent medicines are over-the-counter, patients are advised to consult a doctor or pharmacist when Chinese and western medicines are used together: if they are not suitable for taking at the same time, they should avoid using them together, adjust the dosage due to illness, and stagger the medication time.
