Antibiotics are powerful drugs to fight bacterial diseases. Their misuse, however, may create resistance.

Antibiotics work by killing bacteria or preventing these from reproducing. In the first case are termed bactericidal, while in the second known as bacteriostatic. It should be noted that antibiotics have no effect on viruses, so they are not useful to fight flus, colds or most sore throats and bronchitis. Moreover, taking antibiotics in these cases causes more harm than good. Keep in mind that whenever you take antibiotics, the bacteria found in the body become resistant, hence the importance of taking them only when strictly necessary. Equally important is to finish the full course, even when symptoms have subsided. Nor is it advisable to keep antibiotics, let alone take antibiotics equivalent of another person or another recipe. Can be counterproductive.

 

History of antibiotic

Infectious diseases have decimated the human population, causing millions of deaths throughout history. With the discovery of antibiotics this situation changed dramatically, so much to talk about an unmitigated victory against infection by microorganisms. That is, until the onset of AIDS in the eighties. Currently, infectious diseases show an emerging trend and challenge for medical knowledge.

The history of antibiotics began in 1928, when British scientist Alexander Fleming accidentally discovered penicillin . It took ten years for it to be concentrated and studied through the work of Ernst Boris Chain, Howard Walter Florey and other scientists. Florey and Chain would use penicillin for the first time in humans in 1940 in the wake of Fleming. All three receive the Nobel Prize in 1945. A year before this event, Selman Waksman, who first used the term antibiotic, check erythromycin . But the actual starting point for the effective treatment of infections due to the introduction of the kanamycin in 1957.

Basic Principles for the antibiotic treatment

Whenever there is a possibility must be obtained a sample of infected material and proceed to microscopic analysis together with a crop. This will find the germ that causes as well as resistance to various antibiotics. Once determined, the antibacterial spectrum is decided to be based on the pharmacokinetics , potential adverse reactions, evidence on efficacy and patient status (pregnancy, lactation, AIDS, age, sex, immune status, viral infections, allergies, etc.

Common mistakes and misuse of antibiotics

The antibiotic action has proved their effectiveness, however, for best results must follow specific guidelines. Also must provide certain side effects, which are highly variable and depend on each antibiotic. The most common errors are:
¤ Choosing an antibiotic ineffective.
¤ Inadequate doses.
¤ Employment in viral infections.
¤ Continuation of medication after they have been developed bacterial resistance.
¤ Continued use even when it manifests a toxic or allergic reaction.
¤ Premature discontinuation of treatment.
¤ Do not modify the chemotherapy to appear superinfections with resistant organisms.
¤ Make use of unsuitable combinations.
¤ Trust in excess of chemotherapy or prophylaxis, excluding alternatives like surgery.

Antibiotics and alcohol

Although generally the recommendations are directed not to drink alcohol in any case for its possible negative interaction with the drug, the truth is that the antibiotic is not usually lose their properties or effects if you drink alcohol in moderation. The contraindication for total alcohol applies only to a specific and limited number of antibiotics such as metronidazole, since in this case can have side effects such as tachycardia. In any case, do not drink alcohol while taking the drug is undoubtedly the safest preventive measure to avoid any complications.
