The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic. Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing. However, these classifications are based on laboratory behavior.
Antimicrobial. An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth (bacteriostatic agent). [1] Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi.
Legal status. In Wikidata. An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1][2] They may either kill or inhibit the growth of bacteria.
1942 – gramicidin S, the first peptide antibiotic. 1942 – sulfadimidine. 1943 – sulfamerazine. 1944 – streptomycin, the first aminoglycoside [2] 1947 – sulfadiazine. 1948 – chlortetracycline, the first tetracycline. 1949 – chloramphenicol, the first amphenicol [2] 1949 – neomycin. 1950 – oxytetracycline.
A broad- spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, [1] or any antibiotic that acts against a wide range of disease-causing bacteria. [2] These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy) or ...
Penicillins (P, PCN or PEN) are a group of β-lactam antibiotics originally obtained from Penicillium moulds, principally P. chrysogenum and P. rubens. Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation [2] and then purified. [3][4] A number of natural penicillins have been discovered, but only two ...
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
The WHO AWaRe Classification is a method to categorize antibiotics into three groups in an effort to improve appropriate antibiotic use. [1][2] The classification is based, in part, on the risk of developing antibiotic resistance and their importance to medicine. [1][3] It does not reflect effectiveness or strength. [4]
