Antibacterial drugs: rational use, health care

In the field of modern medicine, antibacterial drugs are one of the most important drugs that play an indispensable role in combating bacterial infections and saving lives. However, with the widespread use of anti-bacterial drugs and the increasing use or even abuse of these drugs, the resulting problems pose a serious threat to public health. Therefore, a comprehensive and in-depth understanding of anti-bacterial drugs and learning to use them correctly and rationally is essential for all of us.Antibacterial drugs, a class of drugs capable of inhibiting or killing bacteria, are of a wide variety and, depending on the chemical structure, can be divided into the following categories:Beta-nimide: This is the most widely applied antibacterial drug in clinical practice, including penicillin and headbactrin.Large ringed esters: erythrin, achicin, etc. are common.Amino sugar slurry: Quintacin, cystacin, etc.The four cyclic groups: e.g., tetracycline, Dossi cycline, etc.Artificial antibacterial drugs: e.g. quinone-type drugs, including non-fluorinated salsa, left-oxen salsa, etc.Antibacterial drugs are used when bacteria enter the human body and reproduce in large numbers, causing symptoms of infection. They contain or eliminate bacteria through a variety of unique mechanisms of action. However, if antibacterial drugs are used unreasonably, they will be like a double-edged sword, with many risks to our health.Toxic side effects: Antibacterial drugs can also have adverse effects on human cells and tissues, while killing bacteria. For example, some people may have allergic reactions such as rashes, itchings, etc., following the use of anti-bacterial drugs because the human immune system treats drugs as foreign harmful substances and attacks. There are also anti-bacterial drugs that may affect gastrointestinal function and lead to symptoms of discomfort, vomiting and diarrhoea.Resistance: This is an extremely serious public health problem facing the world today. When antibacterial drugs are used unreasonably, such as underdoses, inadequate treatment or frequent substitution of drugs, bacteria have the opportunity to adapt and to evolve into resistant strains in the “combat” of drugs. These drug-resistant strains are no longer sensitive to antibacterial drugs that are otherwise effective. As drug-resistant strains grow, infectious diseases that could otherwise be easily cured become difficult to treat and may even lead to dire situations where there are no drugs available.Double-infection: In the oral, intestinal and respiratory parts of the human body, there are a large number of normal strains, which limit each other, are interdependent and maintain a delicate balance. However, when antibacterial drugs are used, especially in the broad spectrum of antibacterial drugs, they can also kill a large number of normal strains by mistake while killing the fungi. At this point, fungi or drug-resistant bacteria, which are already in a vulnerable position, take advantage of the opportunity to reproduce in large numbers and cause double infections.Low immunity: If over-reliance on antibacterial drugs occurs at the beginning of the infection, the human immune system will not be able to fully perform its role and exercise as it should. In the long run, the functioning of the immune system will diminish, resulting in low human immunity. As a result, when bacterial infections are repeated, the body becomes more vulnerable to disease and recovery may be extended.To avoid these hazards, we must use antibacterial drugs correctly. In the use of anti-bacterial drugs, the “four-no” principle should be observed:Non-purchase: Antibacterial drugs are prescribed drugs, which means that they need to be diagnosed and directed by a specialist physician. We cannot afford to buy antibacterial drugs on the basis of our own judgement or the experience of others. Because different types of bacterial infections require different types of antibacterial drugs for treatment, and even infections with the same symptoms can be different.Non-selective: There are many types of antibacterial drugs available on the market, each with its own specific antibacterial spectrum, adaptability, adverse reactions and taboos. We, the general population, lack professional medical knowledge and clinical experience to determine precisely which antibacterial drugs fit our own case. If the drug is chosen, it is likely that the wrong drug will be chosen, resulting in ineffective treatment and even delay.Non-arbitrary: anti-bacterial drugs must be used in strict accordance with the dose prescribed by the doctor, the route of delivery and the course of treatment. Inadequate doses may prevent the complete elimination of bacteria, leading to re-emergence of infections or resistance of bacteria; excessive doses increase the toxic side effects of drugs and cause physical harm. Access to medication is also important, as different antibacterial drugs may have different modes of delivery, such as oral, injection and external use, and doctors may choose according to the severity of the condition and the characteristics of the drug.Do not stop: This is closely linked to non-admissibility. Even if the symptoms are mitigated during the course of the drug use, it cannot be stopped without permission. Because the bacteria in the body may not have been completely eliminated at this time, if the detoxification is premature, the bacteria will have the opportunity to re-emerge, and because of the “pressure” of the drugs they were previously subjected to, they may have developed some resistance and re-treatment will become more difficult.Antibacterial drugs are our powerful weapon against bacterial infections, but only their correct and rational use can maximize their impact while avoiding harm to our own health. Let us develop the right idea of the use of drugs, the rational use of anti-bacterial drugs under the professional guidance of doctors, and the protection of our health together.
