What are the classifications of antibiotics?
In this portal, antibiotics are classified into one of the following classes: penicillins, fluoroquinolones, cephalosporins, macrolides, beta-lactams with increased activity (e.g. amoxicillin-clavulanate), tetracyclines, trimethoprim-sulfamethoxazole, lincosamides (e.g. clindamycin), urinary anti-infectives, and other …
What is the generation of antibiotics?
Antibiotic Classification & Mechanism
Inhibits Cell Wall Synthesis | |
---|---|
Penicillins (bactericidal: blocks cross linking via competitive inhibition of the transpeptidase enzyme) | |
1st generation | Nalidixic acid |
2nd generation | Ciprofloxacin Norfloxacin Enoxacin Ofloxacin Levofloxacin |
3rd generation | Gatifloxacin |
What is second generation antibiotics?
What are Second generation cephalosporins? Cephalosporins are a large group of antibiotics derived from the mold Acremonium (previously called Cephalosporium). Cephalosporins are bactericidal (kill bacteria) and work in a similar way to penicillins.

Which is the highest classification of an antibiotic?
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.
Is there a timeline for the development of antibiotics?
Unsourced material may be challenged and removed. This is the timeline of antimicrobial (anti-infective) therapy. The years show when a given drug was released onto the pharmaceutical market. This is not a timeline of the development of the antibiotics themselves.
What was the use of antibiotics in ancient Greece?
Bactericidal antibiotics kill the bacteria whereas bacteriostatic antibiotics halt the growth of bacteria. History of antibiotics can be described in two segments as under: Greeks and Indians used moulds and other plants to treat infections. In Greece and Serbia, mouldy bread was traditionally used to treat wounds and infections.
Who was involved in the discovery of antibiotics?
History of antibiotics can be described in two segments early history and modern history. Most important is the discovery of pencillin by Alexander Fleming.
