What are Antibiotics?

Any type of bacterial infection can cause great suffering and a lot of health problems to a person. In case of such kind of infection it is common to use antibiotics or medicines which are indicated to kill and prevent bacteria from growing in the body. Bacterial can enter the body by different ways. When it comes to the body, it starts multiplying and the body reacts by inflammation, pain, fever, skin reactions and other ways to prevent intoxication and other harm caused by bacteria.

Naturally our body has certain cells fighting against germs, still their work may be insufficient to stand against these microorganisms. Then special medicines should intervene in the situation.

Antibiotics are called so due to their ability to cope with bacterial development and prevent any damage to the body and its systems. We cannot see or feel the bacteria because of their tiny size, still bacteria can cause such severe disorders as tuberculosis, salmonella, shigella dysentery, syphilis, meningitis, anthrax, plague and others.

Antibiotics are invented to kill the bacteria in the body. Besides, they stop the spread and multiplying of them. First type antibiotics were derived from the microorganisms having antibacterial features. Mr. Alexander Fleming designed antibacterial drugs and since that time more and more antibacterial agents appear to fight the bacterial diseases.

Nowadays, new semisynthetic and synthetic medicines are created. Some of the modern antibacterial agents combine two active components which make them more effective against the severe forms of disorders. Modern antibiotics possess high efficacy and cause practically no harmful effects in patients.

Antibiotics can be grouped into two big classes: bacteriostatic and bactericidal. The first class of antibacterial agents makes it impossible for the bacteria to grow and the second – bactericidal destroy bacteria completely or kill them. In addition to this, antibiotics can be broad –spectrum and narrow-spectrum. Narrow spectrum antibiotics work against particular kinds of bacteria.

Broad –spectrum antibiotics can be used against many kinds of infections caused by different types of bacteria. Antibiotics should be given to the patients when other medications have no effects against the microorganisms. The antibiotic choice is a business of a doctor. What antibiotic to use may depend on the infectious disease, its severity, other health disorders which a patient may have and medicines he/she may be using. Specific antibiotics fight against specific diseases.

The dosage also depends on the same factors and is usually adjusted by the doctor. Antibiotics in tab or liquid or powder forms are taken orally with or without food. Injections are usually made at a doctor’s office. It is obligatory to visit a doctor before using any type of antibiotic. The incorrect use of these medications can lead to serious health risks including allergic reactions, rashes, and dizziness or fainting. Still the most common side effect of antibiotics is stomach problems.

One of the most unpleasant is diarrhea. Other side effects may be vomiting, nausea, headache, stomach upset, fungal infections of digestive tract, female reproductive organ, and mouth. If a patient experiences sever adverse effect of antibiotic, he/she should immediately stop taking it and consult a doctor. Proper taking of antibiotics will help to avoid any risks to health.
