A drug used to treat infections caused by bacteria and other microorganisms is known as Antibiotics. It is a compound or substance that kills or slow down the growth of bacteria. Originally, an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another.Few Antibiotics are tetracycline,penicillin and many more.
When infection attacks the body, anti-infective drugs can suppress the infection. Four types of anti-infective or drugs exist: antibacterial (antibiotic), antiviral, antitubercular, and antifungal. Depending on the severity and the type of infection, the antibiotic may be given by mouth, injection or may be applied topicallyThe symptoms of an infection affect the whole body generally, such as fatigue, loss of appetite, weight loss, fevers, night sweats, chills, aches and pains. Others are specific to individual body parts, such as skin rashes, coughing, or a runny nose..
The quinolones are a family of synthetic broad-spectrum antibacterial drugs The first generation of the quinolones begins with the introduction of nalidixic acid in 1962 for treatment of urinary tract infections in humans.[4] Nalidixic acid was discovered by George Lesher and coworkers in a distillate during an attempt at chloroquine synthesis. They prevent bacterial DNA from unwinding and duplicating.[6] (See Mechanism of Action). Quinolones, in comparison to other antibiotic classes, have among the highest risk of causing colonization with MRSA and Clostridium difficile.
