English biologist Fleming in 1929 discovered the primary antibiotic – antibiotic drug. This was one of the most significant discoveries of the XX century. The new era has begun in biology and drugs – the age of antibiotics. They were treated as a curative, as they coped with the treatment of diseases antecedently thought of hopeless.
The term “antibiotic” springs from 2 Greek words: “anti” – “against” and “bios” – life. It was first proposed by Professor Waxman in 1942. (Although the mildew employed in Greece and ancient Rome, solely then they weren’t referred to as antibiotics.) Antibiotics – medication of microbic, animal or vegetable origin by selection inhibit the very important activity of certain genera and species of microorganisms. This is the most numerous group of drugs. Thus, in Russia nowadays is employed quite two hundred medication (not tally analogs). They are grouped according to certain qualities, despite the differences in chemical structure and mechanism of action. There are antibiotics with antibacterial, antifungal, antiviral and antitumor activity.
Specificity of antibiotics is that, in contrast to most different medication, they operate at the cellular level. However, their activity is not constant: it decreases with time. This is caused by the formation of drug – the inevitable biological phenomenon). The fact that bacteria are somehow “similar” to rats, which had already become accustomed to the poison known to them and then eat these poisons like a harmless powder. And another trouble: microorganisms that become proof against bound antibiotics prolong to infect people, so to deal with them need is a new antibiotic.
The first antibiotics were terribly straightforward and had too several shortcomings, namely: serious side effects, many contraindications, and the need for frequent and prolonged use of drugs, fast habituation. For decades, many countries carried out intensive work to create new generations of antibiotics. In recent years the pharmaceutical market out merchandise of the XXI century, which cause far fewer side effects and, more importantly, “do not give the addiction. Allow them enough to only 2 times a day, as their effect lasts for 12 hours (intravenously – 8 hours). Those are antibiotics such as Maxipim, Meron, Rocephin and others.
Antibiotics facilitate United States get eliminate several diseases, and often we ourselves “prescribe” a treatment. But they’re aloof from harmless, as do most other drugs. The information provided on our web site, help you understand when antibiotics – medication, and when – the poison, and avoid mistakes in their application. By its chemical structure of antibiotics square measure divided into twelve main teams. Therefore, we will consider antibiotics for groups to get a clearer picture of their action.
