It is common sense to take medicine with boiling water, but some people like to take medicine with hot water above 50-60 degrees Celsius. As we all know, some drugs will have physical or chemical reactions after being heated, which will affect the curative effect.
First, help digestion. Such as pepsin mixture, trypsin, multienzyme tablets, yeast tablets and the like. , all contain digestive enzymes. Enzyme is an active protein, which will solidify and denature when heated. "Instructions for Clinical Use of Pharmacopoeia of China and China" points out: "Pepsin is unstable when exposed to heat, and it will lose its efficacy above 70 degrees Celsius".
Second, vitamins. For example, vitamin C is unstable and easily reduced and destroyed after heating, thus losing its efficacy.
Third, cough syrup. Jizhi syrup, compound licorice mixture, honey-baked Fritillaria loquat cream, etc. Is a medicine prepared by dissolving antitussive and anti-inflammatory components in syrup or extract. After the patient takes it, the syrup or extract covers the inflamed pharyngeal mucosa to form a protective film, which is convenient for quickly controlling cough and relieving symptoms. If you take it with hot water, it is easier to reduce the viscosity of syrup and affect the curative effect of protective film.
Fourth, live vaccine. For example, polio sugar pills contain live attenuated polio vaccine, which should be taken with cold boiled water, otherwise the vaccine will be inactivated, and it will not play a role in immunizing the body and preventing infectious diseases.
Five, containing active fungi. Lactobacillus, Bacillus licheniformis, Streptococcus faecalis and Bacillus subtilis, and the synbiotics (children's probiotic granules) contain Lactobacillus acidophilus and Bifidobacterium. In addition, yeast tablets, Livzon Changle and other drugs all contain active bacteria to prevent and treat diseases. Active bacteria will be destroyed when heated.
Sixth, heat-clearing Chinese patent medicine. Chinese medicine believes that the symptoms of dryness and heat, such as fever and excessive internal heat, should be treated with heat-clearing agents, and hot water should not be used at this time. Taking it with cold boiled water can increase the efficacy of antipyretic drugs.
Eat Liuwei Dihuang pills and drink light salt water.
Liuwei Dihuang Pill is a commonly used Chinese patent medicine, which is composed of six traditional Chinese medicines and has the effect of nourishing kidney yin. It is often used to treat kidney yin deficiency, dizziness, tinnitus, soreness of waist and knees, night sweats and nocturnal emission. Liuwei Dihuang Pills are mostly honey pills, and people usually take them with warm boiled water. In fact, the best way is to use warm and light salt water.
In order to better improve the therapeutic effect or deal with some complicated diseases, Chinese patent medicines are often used in combination. Second, the compatibility of Chinese patent medicine and decoction; The third is the compatibility of Chinese patent medicine and drug introduction, which mainly uses drug introduction to guide drugs to the focus to improve the curative effect.
Liuwei Dihuang Pill is taken with light salt water, which is the compatibility of traditional Chinese medicine and drug introduction. Salt is also a traditional Chinese medicine, which is salty and cold, and has the functions of clearing fire, cooling blood and detoxifying. Because of its salty taste, the drug can be introduced into the kidney, so it can be used as a drug introduction to help Liuwei Dihuang Pill reach the focus directly and play a better role in tonifying the kidney. In addition, for patients with kidney yin deficiency and deficiency fire, the cold nature of salt can be used to clear fire.
Other Chinese patent medicines that should be taken with light salt water include Jinsuo Gu Jing Pill, Shen Si Pill, Nitin, Dabuyin Pill, Zuogui Pill, Zuo Ci Pill and Qian Hu Pill. Most of them are drugs for treating kidney deficiency.
Mineral water is unscientific.
In addition to the amount of drinking water, different water quality will also have different effects on the efficacy. For most drugs, boiled water is the best.
Tea can relieve greasy, help digestion, induce diuresis, relieve constipation, and help prevent coronary heart disease and hyperlipidemia. However, it contains a lot of tannins, which are easy to interact with protein, alkaloids and metal ions in drugs. For example, iron-containing blood, tannins and iron will produce precipitation, hindering the absorption of iron. Protein-containing digestive enzyme preparation will also combine with tannin, reducing the efficacy. In addition, caffeine in tea has antagonistic effect on sedatives, which will also reduce their efficacy. So, don't drink tea and take medicine.
Mineral water is becoming more and more common in our life, but some minerals and metal ions, such as calcium, will also affect some drugs. The instructions indicate that tetracycline antibiotics, alendronate sodium and other drugs are strictly forbidden to take with calcium preparations, and try not to take with mineral water.
Recently, orange juice has been found to interfere with some drugs in liver metabolism, which will hinder its metabolism and thus enhance its toxicity. For example, statins for regulating blood lipids, celilol for treating heart disease, etc. Therefore, the above drugs are not only forbidden to be taken with fruit juice, but also try not to drink fruit juice during taking medicine.

Don't drink water for 5 minutes after taking cough syrup.
Cough syrup is an over-the-counter drug that is often used in daily life. Because of its good taste and convenient administration, it is deeply loved by cough patients, especially children and the elderly. Some people are used to drinking a lot of water immediately after taking syrup, thinking that this can quickly get rid of the special taste of the medicine and send the liquid medicine into the gastrointestinal tract as soon as possible. In fact, this is not conducive to the efficacy of cough syrup.
This is because, on the one hand, the antitussive effect of cough syrup depends on gastrointestinal absorption, on the other hand, it depends on the syrup covering the surface of pharyngeal mucosa to directly reduce the stimulation of inflammation. If you drink plenty of water immediately after taking the medicine, you will first reduce the drug concentration in the pharynx and then dilute the gastric juice, which will affect the absorption of the drug in the gastrointestinal tract. Therefore, some doctors will advise patients not to drink water for at least 5 minutes after drinking syrup to improve the curative effect. However, if the thick syrup stimulates the pharynx too much and even causes discomfort, that is another matter.
