Antibiotics: what is it ?

Antibiotics: what is it ?
France is one of the countries where it consumes the most antibiotics. These products are used in the fight against bacterial infections … and not against viruses. Small inventory of the therapeutic arsenal available to your doctor.

Often antibiotics are compounds derived from substances isolated in nature. Penicillin, for example, was discovered by chance by Sir A. Fleming in 1928 when he tried to understand why he cultivated bacteria in his laboratory were dead. He finally realized that mold the kind Penicillinum naturally producing penicillin was introduced in its culture dishes!

Various modes of action

Today, there are a large number of antibiotics whose modes of action are varied. Some act on the wall or membrane of the bacteria causing their destruction. Others will act on the machinery of bacteria to block their development and survival. Finally, some antibiotics act directly at the level of their DNA to prevent their division and proliferation.

Antibiotics, particularly penicillins and cephalosporins may cause serious allergic reactions or death. Therefore always tell your doctor or pharmacist know if you are allergic to certain antibiotics.

Effects on the intestinal flora

Taken orally, the prolonged antibiotic treatment can cause undesirable gastrointestinal effects such as diarrhea. Indeed, our gut contains a large number of non-pathogenic bacteria (which do not cause disease) and useful in our digestion. These bacteria make up our intestinal flora. They will facilitate the degradation of our food, making possible their assimilation by the body. Prolonged use of antibiotics can cause death of a number of these bacteria and thus disturb our digestion.

While respecting prescription

At the same local antibiotic treatment, it should be well respected prescribing doctor and particularly the dose and duration of treatment. Indeed, stopping treatment as soon as you feel an improvement and before this treatment is completed may favor the emergence of bacteria resistant to the action of the antibiotic and cause a relapse. This resistance will make it more difficult new treatment.

All infections are not treatable with antibiotics. The use of an antibiotic (and any medication in general) makes sense only if it is effective against the disease we want to treat. Viral infections in particular are not susceptible to antibiotics and most colds and other viral origins are nasopharyngitis! In some cases, the prescription of an antibiotic may still have an interest in avoiding a bacterium come infect the subject already weakened.

Similarly, oral administration of an antibiotic on its own should be banned because only a doctor is able to know the antibiotic that matches your infection. Taking an inappropriate antibiotic may worsen the infection, so always consult your doctor.
