Amoxicillin: Frequently Asked Questions Answered
What is amoxicillin?
Amoxicillin is a penicillin-based antibiotic and is a close relative of ampicillin. It can kill bacteria like the Streptococcus species, E. coli, Listeria monocytogenes, Actinomyces, Shigella, Salmonella, and Clostridial species. This antibiotic belongs to a specific class of beta-lactam drugs.
Amoxicillin works by inhibiting specific bacterial cells. The proteins function to bind and break down bacterial walls. This process is called bactericidal killing.
The different brand names that amoxicillin is available under are Amoxil, Moxatag, and Trimox.

- Pneumonia
