Antibiotics, Antimicrobial & Chemotherapy

Antibiotics are a group of medicines that are used to treat infections caused by some germs like bacteria and certain parasites). Usually, people those who need to have an antibiotic by injection are in hospital because they have a severe infection. Whereas, Antimicrobial chemotherapy is the clinical application of antimicrobial agents to treat infectious disease. It involves the administration of drugs with selective toxicity against pathogens concerned in infections, not host cells. Chemotherapeutic agents also known as synthetic antibiotics are the antimicrobial agents of synthetic origin useful in the treatment of microbial or viral disease. Few examples are sulfonilamides, isoniazid, ethambutol, AZT, nalidixic acid and chloramphenicol. Chemotherapeutic agent needs that the agent be used for antimicrobial purpose and excludes synthetic agents used for medical care against diseases that are not of microbial origin.
