Antibiotics

chemicals used to kill or inhibit growth. Strictly speaking, antibiotics are a subgroup of organic against infectious agents that are derived from bacteria or mold that are toxic to other bacteria. However, the term antibiotic is being used freely include antibacterial made from synthetic and semi-synthetic compounds. Term antibiotics may be used along with the term antibacterial. However, it is wrong to use the term antibiotic when accessing antiviral, antiprotozoal, and antifungal drugs. Penicillin was the first antibiotic successfully used to treat bacterial infections. Sir Alexander Fleming first discovered it in 1928, but its potential for treatment of infections was not recognized until a decade ago, when Ernst B Chain, Sir Howard Flory and Hitli Norman produced enough purified penicillin to treat patients with. By 1950 a large number of antibiotics were discovered and made for the treatment of diseases caused by infection by bacteria. Over the past 50 years, antibiotics have changed the form of the disease and death. Antibiotics can be classified in several ways. The most common method classifies them according to their chemical structure, as antibiotics sharing the same or similar chemical structure, usually show a similar scheme of antibacterial activity, efficacy, toxicity and allergic potential. Antibiotics only work against infections caused by bacteria. Bacterial infections occur much less frequently than. Most cough and cold have a viral origin so antibiotics should not be prescribed for them. Antibiotics should be used only when strictly necessary because: eg, e. If the infection was left untreated as a result of illness can be serious and even fatal. In severe bacterial infections, where patients can be hospitalized, often intravenous broad spectrum antibiotic (one that is active against various bacteria) is given to start treatment. Once lab tests confirm infection by bacteria, antibiotics should be changed to one that is active against certain bacteria. After 48 hours of intravenous treatment, if there is clinical improvement, the patient may be included in an oral antibiotic. Overuse and misuse of antibiotics has led to resistance to antibiotics. Bacteria strattera price that were once susceptible to antibiotics have developed ways to survive drugs that were supposed to kill or weaken them. It is also known as antimicrobial resistance and drug resistance. Some diseases such as tuberculosis,

and childhood bacterial ear infections that were once easily treated with antibiotics now again becomes difficult to treat as bacteria acquire resistance to these drugs. About 70% of bacteria that cause infections in hospitals are resistant to at least one of the antibiotics most often used to treat infections. (MRSA) is a particular problem for patients with skin diseases, ulcers and surgical wounds. Antibiotics are associated with many side effects. Some side effects associated class, but most reactions, typical agent is that person. Allergy to certain antibiotics or antibiotic classes, e. by penicillin allergy

Many antibiotics cause gastrointestinal problems, e. by diarrhea, vomiting, nausea

antibiotics kill not only their goals but also other beneficial microorganisms that live in and our body (flora) to prevent other diseases, e. by and / or various skin rashes may occur, which can be mild (for example) or destructive (for example). .
