Introduction to antibacterial drugs
In everyday life, we inevitably encounter infectious diseases such as cold, pneumonia, urinary tract infections, etc. In these cases, antibacterial drugs often become an important weapon in our fight against bacteria. However, antibacterial drugs are not a panacea, and their use is subject to certain scientific principles, which could lead to increased bacterial resistance and reduced drug effects.
Antibacterial drugs, by definition, are drugs used to kill or inhibit the growth of bacteria. They achieve antibacterial effects mainly by interfering with the metabolic process of bacteria or destroying their cell structure. It is noteworthy, however, that antibacterial drugs do not directly affect other micro-organisms such as viruses and fungi. Thus, antibacterial drugs do not help to restore health when we face virus-induced diseases such as influenza and flu.
In the use of antibacterial drugs, adherence to medical advice is essential. Doctors select appropriate antibacterial and pharmaceutical programmes based on the patient ‘ s symptoms, signs and results of bacterial development. Patients should strictly follow the doctor ‘ s instructions, including dosage, frequency and length of use. Unauthorized changes in drug use programmes, such as increased, reduced or early withdrawals, can lead to treatment failure or bacterial resistance. Furthermore, we must be clear: anti-bacterial drugs are not effective against viruses. This means that the use of antibacterial drugs is ineffective if we suffer from virus-induced diseases such as common flu, influenza, etc., and may even have side effects from drug abuse. Therefore, in the face of infectious diseases, we should first determine the pathogen type through a doctor’s diagnosis and then choose the drug in a targeted manner.
In addition, the use of anti-bacterial drugs is subject to the principle of “quantifiable, pediatric”. This is because bacteria grow and reproduce in a certain cyclical manner, and if there are insufficient drug concentrations or treatment procedures, bacteria may regenerate when their effects are reduced, leading to repeated cases. At the same time, it may also contribute to the drug resistance of bacteria, making future treatment more difficult.
In addition to following medical instructions, we can take some precautions to reduce the risk of bacterial infection. Maintaining good hygiene practices, such as hand washing, masking and avoiding close contact with infected persons, can effectively reduce the spread of bacteria. In addition, increased physical activity, a balanced diet and adequate sleep can also help to increase our immunity from bacterial infections.
Bacteria resistance is a major challenge to global public health today. When bacteria produce resistance to an antibacterial drug, it will no longer be able to effectively kill or suppress the bacteria. Not only does this mean that patients may need longer and more complex treatments, but it may also lead to the emergence of “superbacterial bacteria” that are untreated. Therefore, the rational use of antibacterial drugs and the avoidance of unnecessary drug use are key to reducing the risk of bacterial resistance.
Antibacterial drugs play an important role in our health system. However, they can be of maximum value only if we properly understand and use them. Only then can we better protect our health and reduce the generation of bacterial resistance. Let us therefore work together to promote the rational use of antibacterial drugs and to contribute to the cause of human health.
