Common misperceptions of antibacterial treatment

In the area of treatment for respiratory diseases, antibacterial treatment is of great importance. However, due to the influence of public ignorance of medical knowledge and partial misinformation, there are many misconceptions about respiratory antibacterial treatment, which may not only delay the condition but also lead to adverse consequences such as increased bacterial resistance.I. “Prevents on antibacterials”Once caught with a cold, many used to take their own antibacterial drugs, such as Amocilin, sepsis, etc. Indeed, most common influenza is caused by viral infections, which include nose viruses, coronary viruses, etc. Antibacterial drugs are mainly for bacterial infections and have no effect on viral infections. The abuse of antibacterial drugs without evidence of bacterial infection not only fails to mitigate cold symptoms, such as nose plugs, fluorine, sores, etc., but can also cause a series of adverse reactions. For example, it can cause gastrointestinal discomfort and symptoms such as nausea, vomiting and diarrhoea; some patients may also have allergic reactions, such as rashes, itchings and even an allergic shock when severe. In addition, the unjustified use of antibacterial drugs undermines the normal micro-ecological balance of the human body, resulting in the excessive growth of some otherwise repressed bacteria, increasing the risk of secondary bacterial infections and creating conditions for bacterial resistance.“New, expensive antibacterials work better”In the choice of anti-bacterial drugs, many patients have the misconception that “the more expensive the better”. They often ignore that the use of antibacterial drugs should be determined on the basis of specific conditions and pathogen types. Each antibacterial drug has its own specific antibacterial spectrometry, i.e., antibacterial activity for specific bacteria. For example, for light-intensity communities with access to sexual respiratory infections, such as pneumonia caused by streptococcus, traditional penicillin or first-generation fungus may be able to control the infection effectively, and the efficacy and safety of these drugs have been fully demonstrated through long-term clinical application, at relatively pro-people prices. However, some new antibacterial drugs, such as carbon pyroacnectoxin, which have hyperbacterial antibacterial activity and are powerful microbicides for a wide range of drug-resistant bacteria, apply mainly to complex situations such as the acquisition of sexual infections and multi-drug-resistant infections in hospitals that treat serious infections. The blind use of these new and expensive antibacterial drugs in common infections is not only a waste of resources, but may also accelerate the resistance of bacteria to them as a result of overuse, while also increasing the risk of adverse reactions to drugs, such as carbon-cyanide-type drugs, which may induce central nervous system toxicity, especially in patients with kidney deficiencies.“Symptomological detoxification”Some patients who use anti-bacterial drugs to treat respiratory diseases cease to use them on their own as soon as the symptoms are reduced, such as the acceleration of the fever and the reduced frequency of coughing. This approach is extremely wrong. Antibacterial treatment is a process that requires treatment and is aimed at the complete removal of pathogenic bacteria from the body and at preventing the recurrence of infection. For example, in the treatment of pneumonia, even if the symptoms of the patient ‘ s fever and cough improve significantly after a few days of medication, there may still be a certain amount of bacteria in the body at this time, which, if taken off too soon, could be replete, leading to repeated cases, making it more complex and difficult to treat what could have been simpler infections. Moreover, this unregulated use of drugs can cause bacteria to remain in a low-concentrated antibacterial environment for long periods of time, making it easier to induce bacteria to produce drug resistance mutations and creating great difficulties for subsequent treatment. In general, doctors determine the course of treatment on the basis of such factors as the patient ‘ s condition, the type of pathogen infected and the characteristics of the antibacterial drugs used, and the patient is required to complete the entire course of treatment in strict compliance with medical instructions.“Multiple antibacterials are better used together”Some patients consider that the use of multiple antibacterials at the same time as respiratory infections can enhance the efficacy of treatment, and then combine their own drugs or require a doctor to prescribe multiple antibacterials. However, the joint use of anti-bacterial drugs is strictly indicated and is not much better. The joint use of antibacterial drugs is required only in specific cases, such as the treatment of a combination of infections (e.g., co-infection of aerobics and anaerobics), serious resistance to bacteria or certain specific pathogens. For example, in cases of co-infection of anaerobic bacteria in the lung with anaerobic bacteria, there may be a need for a combination of antiaerobic drugs (e.g., americium) and antiaerobic drugs (e.g., head gills). But if there is no reasonable basis to combine a wide range of antibacterial drugs at will, it will not only improve the efficacy of treatment, but will increase the incidence of adverse drug reactions. Multiple antibacterial drugs work in humans at the same time, which can increase the burden on organs such as the liver, kidneys and lead to a significantly higher risk of adverse reactions such as hepatotoxicity and renal toxicity. At the same time, unreasonable combinations of drugs can also trigger interactions between drugs and affect the efficacy of drugs, for example, when some combinations of drugs can reduce each other ‘ s antibacterial activity or increase the concentration of drugs in the body, thereby increasing the probability of adverse reactions.“Antibacterials to prevent respiratory infections”Some people mistakenly believe that the early use of antibacterial drugs can prevent infection when respiratory disease is high or when people are around it. In fact, anti-bacterial drugs do not prevent viral infections, and most respiratory infections are initially caused by viruses. Even for the prevention of bacterial infections, the preventive use of antibacterial drugs is subject to strict restrictions, usually only for specific high-risk groups, such as doctors who, prior to certain surgical operations (such as cardiac surgery, joint replacements, etc.), determine, on a case-by-case basis, the preventive use of antibacterial drugs in cases where there is a high risk of specific bacterial infections. The random use of antibacterial drugs for prevention in everyday life not only does not serve the purpose of preventing infection, but rather results in the emergence of bacterial resistance because of the irrational use of drugs, rendering the drugs ineffective when there is a real need for antibacterial treatment.It is urgent to correct these misconceptions in antibacterial treatment, which are widespread in society. Patients, family members and the general public should increase their knowledge of respiratory antibacterial treatment, improve scientific literacy, follow the professional guidance of doctors, and use antibacterial drugs rationally in order to safeguard their health and public health.
