Antibiotics are medications used to treat and cure bacterial infections. These are especially for bacterial infection although some antibiotics have the ability to demolish parasites. It should be understood that these medication are not prescribed as curatives for viruses and other viral infections. Penicillin was the first antibiotics. Some of the antibiotics related to Penicillin are ampicillin, benzylpenicilllin as well as amoxicillin etc; these are widely adopted today to cure different types of infections. These antibiotics formulations have been in use since a long time back. However, there are various types of advanced antibiotics which can be obtained only through a doctor's prescription; buying these drugs over t he counter is almost impossible.
Though there are various antibiotics they may function in either way as mentioned below:
- Bactericidal antibiotic demolishes the bacteria affecting the victim. Penicillin is actually a bactericidal that functions by undermining the development of cell wall of bacteria or even its cell contents.
- A bacteriostatic antibiotic ceases bacteria preventing it from multiplying itself.
In case antibiotics are used in excess then there are fair possibilities of the bacteria turning to antibiotic resistant. In such cases antibiotics becomes less effective and useless against the kind of bacteria. There are other uses of antibiotics for example it is also given before surgical treatments to avoid infections; this use if also scientifically referred to as Prophylactic use of the medicine (antibiotic). Prophylactic use of antibiotics is generally followed prior to orthopedic surgery.
About Side-effects experienced due to antibiotics
Some of the common side effects of antibiotics are
- Diarrhea or looseness
- Sick feeling

Some of the rare but serious side-effects of antibiotics are as follows:
Below mentioned are some main classes of antibiotics:
- In case of sulphonamides Development of kidney stones may occur
- A person may also become sensitive to sun while consuming tetracyclines antibiotics.
- Blood clotting abnormally in case of consumption of certain cephalosporins antibiotics
- Blood releated issues due to trimethoprim antibiotics
- Deafness or impaired hearing ability due to antibiotics such as erythromycin and aminoglycosides.
There are various antibiotics and the one which is suitable for you will be depended on the kind of infection you are suffering from; hence, doctor’s advice seems highly essential in case of bacterial or other infections. Here are some classes of antibiotics.
Antibiotics are extremely important medicines, but the bacteria are capable of developing resistance to them. Antibiotic-resistant bacteria are germs that are not killed by commonly used antibiotics. When bacteria are exposed to the same antibiotics over and over, the bacteria can change and are no longer affected by the drug.
Bacteria have number of ways how they become antibiotic-resistant. For example, they possess an internal mechanism of changing their structure so the antibiotic no longer works, they develop ways to inactivate or neutralize the antibiotic. Bacteria can also transfer the genes coding for antibiotic resistance between them, making it possible for bacteria never exposed to an antibiotic to acquire resistance from those which have. The problem of antibiotic resistance is worsened when antibiotics are used to treat disorders in which they have no efficacy (e.g. antibiotics are not effective against infections caused by viruses), and when they are used widely as prophylaxis rather than treatment.
Resistance to antibiotics poses a serious and growing problem, because some infectious diseases are becoming very difficult to treat. Resistant bacteria do not respond to the antibiotics and continue to cause infection. Some of these resistant bacteria can be treated with more powerful medicines, but there some infections that are difficult to cure even with new or experimental drugs.
