Video: ❶ What Is An Antibiotic
Antibiotics are substances that inhibit the growth of living cells. Their name comes from a combination of two Greek words: "anti" - "against" and "bios" - "life". Some antibiotics that have the ability to inhibit the growth and reproduction of bacteria and at the same time have a weak effect on the cells of the human body are used as medicines. Location: Location: The main purpose of antibiotics is to prevent and treat inflammation caused by disease-causing bacteria. Preparations are both natural and synthetic.
It can be said without exaggeration that the very first antibiotic, which found application as a medicine, made a real revolution in medicine. Its name is penicillin. It has dramatically reduced mortality from inflammation, a natural consequence of infectious diseases and injuries. It is no coincidence that monuments to the discoverer of penicillin J. Fleming were erected in many countries of the world. Streptomycin soon appeared, and then more and more, more effective antibiotics.
The mechanism of the therapeutic action of antibiotics is very different: violation of the synthesis of the cell wall of pathogenic bacteria, violation of the integrity of their intracellular membranes, suppression of the synthesis of their nucleic acids, inhibition of various enzymes, etc. These drugs can be injected into the patient's body in different ways: using injections, tablets, suppositories, skin ointments.
The high efficiency of antibiotics in the fight against pathogenic bacteria led to the fact that people far from medicine began to consider them as a panacea, taking them almost as preventive measures, that is, just in case. And this is completely wrong! First, contrary to popular misconception, antibiotics are absolutely useless against viruses. Therefore, attempts to treat them with flu, chickenpox, measles and other similar diseases not only do not give the slightest effect, but can, on the contrary, harm the body. Secondly, only a doctor can choose the right antibiotic and its dosage. Finally, thirdly, antibiotics can be used only if really necessary, since they have serious side effects: they suppress the intestinal microflora (including beneficial ones),can cause allergic reactions. Remember that self-medication is undesirable and dangerous.
