Is penicillin considered a broad spectrum antibiotic?

Examples of narrow-spectrum antibiotics are the older penicillins (penG), the macrolides and vancomycin. Examples of broad-spectrum antibiotics are the aminoglycosides, the 2nd and 3rd generation cephalosporins, the quinolones and some synthetic penicillins.

Which antibiotics are broad spectrum?

The main examples of broad spectrum antibiotics in humans are tetracycline, ofloxacin and chloramphenicol. Chloramphenicol is found to be rapidly absorbed from the gastro-intestinal tract and hence can be given orally in case of typhoid, pneumonia and dysentery.

What are the broad spectrum penicillins?

The extended-spectrum penicillins which consist of carbenicilllin, mezlocillin, piperacillin and ticarcillin are a group of semi-synthetic penicillin antibiotics that, because of their chemical structure, have a wider spectra of activity than natural penicillins, penicillinase-resistant penicillins (e.g. nafcillin).

Is penicillin V broad or narrow-spectrum?

Penicillin V has activity against Gram-positive bacteria but is less active against Gram-negative bacteria. This drug is among the narrowest-spectrum antibiotics in use.

Why is penicillin called a narrow-spectrum antibiotic?

Narrow-spectrum antibiotic allow to kill or inhibit only those bacteria species that are unwanted (i.e. causing disease). As such, it leaves most of the beneficial bacteria unaffected, hence minimizing the collateral damage on the microbiota. Low propensity for bacterial resistance development.

Is amoxicillin broad or narrow spectrum?

The American Academy of Pediatrics recommends penicillin or amoxicillin, which are both narrow-spectrum antibiotics, as first-line therapy for most children with acute otitis media8; however, clinical trials have used amoxicillin-clavulanate, which is a broad-spectrum antibiotic, to compare with placebo for acute …

Is amoxicillin broad spectrum?

Is amoxicillin a broad spectrum penicillin?
