Can Danshen Tablet be taken for a long time? Compound Danshen Tablet (composed of Danshen, Notoginseng Radix and Borneolum Syntheticum) is a Chinese patent medicine for promoting blood circulation, removing blood stasis, regulating qi and relieving pain. It is mainly used for angina pectoris (coronary heart disease), hypertension, cervical spondylosis and oppression in the chest.
Because of its reliable efficacy, small side effects and low price, compound Danshen tablets have become one of the Chinese patent medicines with high frequency of use.
However, taking compound Danshen tablets for a long time may cause the decrease of blood potassium content and produce hypokalemia. It is found that some patients with coronary heart disease take Compound Danshen Tablet 1 month continuously according to the routine dosage, and the blood potassium level is lower than that before treatment, and patients may have symptoms of potassium deficiency such as abdominal distension and fatigue.
Although Salvia Miltiorrhiza has a slow effect of lowering potassium, it may be induced by long-term medication, and most of the patients taking the medicine are elderly patients. Once hypokalemia occurs, the influence on heart, muscles, central nervous system, digestion and acid-base balance will be more obvious, which may cause serious consequences.
Therefore, in the process of taking this medicine, the elderly should pay attention to proper potassium supplementation, and generally can often eat some potassium-rich foods, such as bananas, orange juice, soybeans, peanuts, mushrooms, potatoes, sweet potatoes and so on. When there are symptoms of potassium deficiency such as abdominal distension and fatigue, potassium salt can be added.
? Old medicine? With the development of medical research, new pharmacological effects of many drugs have been gradually discovered and applied in clinic, thus opening up new ways of drug use. So-called? Old medicine? Refers to the drugs that have been put on the market for clinical use for a long time and have been known by the majority of medical personnel or social groups, and? New use? That is to say, these drugs have found new uses in clinical practice.
For example, the well-known aspirin was originally an antipyretic, analgesic and anti-rheumatic drug, but in recent years it has been found that it can also reduce blood viscosity and can be used to prevent and treat myocardial infarction and other diseases. Nowadays, many newspapers and magazines publish some common old drugs as popular science propaganda and reports, but there are many people who abuse them without analyzing or combining with reality, grasping strict indications, not following doctor's advice, which is not conducive to safe and effective drug use and will be counterproductive. In my opinion? Old medicine? New use, we must be cautious.
First of all, in the social crowd, most of them are non-medical professionals, as the saying goes: Does the medicine have three poisons? 、? Medicine is like a knife, can kill people? If you use it rashly, you may have adverse reactions. At the same time, even if some old drugs are to be used newly, they must be comprehensively analyzed and carefully considered under the guidance of medical professionals with rich practical experience, and the reports must never be biased. For example, it is reported that BCG, a drug for preventing tuberculosis, can be used to treat hepatitis B, chronic bronchitis, verruca plana and nephritis, but patients should never use it. This is because there are live mycobacterium tuberculosis in BCG, and if used rashly, there is a danger of causing tuberculosis.
In fact, many old medicines? New use? Its mechanism is still unknown, or it must meet certain conditions when used. It is reported that vitamin E can treat epilepsy, but this is only an auxiliary method, and the drug has no direct anti-epileptic effect. Some old medicine? New use? There are strict indications. For example, it is reported that vitamin B6 can treat mastitis, but it is only suitable for the early stage of acute stage, but it is useless in the suppurative stage.
Many reports on the new use of old drugs have few clinical observation cases, lack of controlled experiments, or can not stand repeated experiments. It is inevitable or accidental, so it is necessary to study them. Have some old drugs been used in new ways that ignore individual differences or have not been taken into account? New use? The possibility of future adverse reactions.
For example, it is reported that aspirin can prevent cancer, and it is introduced that the American Cancer Society has conducted an experiment among 600,000 volunteers for six years. The observation result is that people who take 16 or more aspirin orally every day can reduce the risk of colon cancer by 40%. Whether such a large dose of oral medicine is suitable for Chinese people and its adverse reactions cannot be ignored.
The United States is also very cautious about the new use of old drugs. For example, the new use of aspirin has been found in clinic for many years, and many pharmacological studies and clinical observations have been carried out. Although it has been found to have new uses, it was not until 1998 that the final regulation was promulgated, allowing aspirin to expand its indications.
Even so, there are only two new indications for aspirin: for the treatment of acute myocardial infarction and for the prevention of stroke. This product is an over-the-counter drug in the United States, but its new function does not appear in the drug instructions used by consumers.
The description of OTC drugs is only in the instructions provided by manufacturers to doctors and in publications such as "Doctor's Desktop Reference". Although the final regulations on the above new uses of aspirin have been published in the Federal Register, the FDA has stated that patients cannot take drugs on their own for the above indications.
