This group includes a huge number of drugs with different chemical properties. Their common link is that they all stop the growth and multiplication of bacteria. It should be noted that in the human body and its surface is home to hundreds of species of microbes. The total weight of bacteria normally inhabit the intestine - more than a kilogram! All these microorganisms perform many useful functions for humans. Perhaps the chief among them - they are not allowed in their local environment outsiders, thereby protecting us against many infectious diseases.
One of the difficulties in the use of antibiotics is that they kill both bacteria and helpful, so the indications for their intended use must be strictly weighed and their appointment shall be carried out by a doctor. The grounds for the appointment of antibiotics is the doctor's conviction that the inflammation is caused by bacteria, not viruses because a virus antibiotics do not work, and the majority of intestinal infections and colds are viral in nature.
The second problem associated with antibiotic therapy, is that not all drugs of this group act on all of the bacteria. Therefore, the selection of a particular drug is carried out based on the ideas of what kind of bacteria caused the disease. But even in this case can not be completely sure that an antibiotic will help, as many organisms over the years the use of antibiotics have developed resistance to their effects (resistance). Information about what the frequency of resistant strains of specific microbes to specific drugs are constantly being updated and is heard to doctors. Based on these data, make recommendations to doctors about what drugs are better used.
Of course, that patients are not able to choose the correct effective drug, so it's best to do it the doctor. The uncontrolled use of antibiotics, especially powerful, increases the number of resistant strains of pathogens. For the treatment of diseases caused by these strains are required more and more potent antibacterial agents, often have severe side effects.
Another important thing to remember the patient is assigned to an antibacterial drug. Need to take it all the time, which is prescribed by your doctor and adhere strictly to the reception. It often happens that after one or two days of drops the temperature decreases or disappears symptoms that concern to the patient, and he stopped taking medication. So you can not do in any case, since it can lead to chronic illness, and development of complications, a new outbreak of the disease. And the same antibiotic may not help in this case, it is necessary to change it to another. In addition, the incomplete destruction of bacteria leads to the appearance among them stable (resistant) strains.
