Reasonable use, health care.

Rational use, safeguarding health, is in the medical field, and antibacterial drugs are a key defence against bacterial infections, but their use requires caution. Knowledge of anti-bacterial drugs is essential for us to make the right use of this medical resource and to ensure our own health.Antibacterial drugs are of a wide variety and include, inter alia, penicillin, sepsis, caramino sugar, large ringed esters and tetracyclics. Penicillin is the first antibacterial drug to be found and applied, such as Amocilin, which has good antibacterial activity in a variety of grelan-positive bacteria and parts of grelan-vagina, and is widely used for the treatment of infections such as respiratory, urinary and other infections. As algebras develop, the antibacterial spectroscopy expands and has a better effect on a wide range of drug-resistant bacteria, each of which has characteristics of resistance from the first to the fourth generation.Antibacterial drugs also operate in a variety of mechanisms. Some cause bacteria to break down in low-permeability environments by inhibiting the synthesis of bacterial cell walls, such as β-nimide antibiotics; others affect the synthesis of bacterial proteins and interfere with the growth and reproduction of bacteria, such as amino sugar. These different mechanisms of action determine their lethal effects on different bacteria.However, the abuse of antibacterial drugs is a cause for concern. It is very dangerous for many patients to buy antibacterial drugs on their own when they experience heat, cough, etc. On the one hand, most upper-respiratory infections are caused by viruses, and the use of antibacterial drugs not only does not work against viruses, but may also disrupt the normal population balance of humans. There are a large number of normal strains in the skin, mouth, intestinal tract of the human body, which can help us protect against invasive alien pathogens, and the abuse of antibacterial drugs may lead to the inhibition of these useful strains, leading to other health problems, such as diarrhoea, fungi infection, etc.On the other hand, the abuse of antibacterial drugs accelerates the emergence of bacterial resistance. When bacteria undergo long-term exposure to antibacterial drugs below their active concentration, they gradually adapt to the environment and create resistance against the bacterial drugs by changing their structure or metabolic route. The emergence of drug-resistant bacteria has rendered ineffective antibacterial drugs that were otherwise effective and made the treatment of infections difficult. For example, the treatment of the infection of the methoxoxylin-yelloccus (MRSA) is far more difficult than that of the common golden fungus infection, requiring the use of higher-grade, more expensive antibacterial drugs and possibly even untreated.In order to rationally use anti-bacterial drugs, we must follow some basic principles. First, before using anti-bacterial drugs, medical treatment must be made available to a doctor for diagnosis. Doctors select appropriate antibacterial drugs based on the area of the infection, symptoms, possible pathogens and the individual circumstances of the patient, such as age, liver and kidney function. Second, anti-bacterial drugs are used on time and in accordance with medical instructions, and do not increase or reduce the dose or stop the drug. A complete course of treatment is essential for the complete eradication of bacteria and the prevention of drug resistance. In addition, we must avoid the preventive use of anti-bacterial drugs unless there are clear indications, such as those used for certain periods of time in order to prevent infection prior to certain operations.Antibacterial drugs are a powerful weapon for humans against bacterial infections, but only if we use them properly can they really work to protect our health while slowing the development of bacterial resistance and retaining effective means for future medical treatment. Each of us should be the custodians of the rational use of anti-bacterial drugs, beginning with ourselves, so that this precious medical resource can continue to benefit humankind.
