Which of the following is a brand name for Amoxicillin?

Amoxicillin is a commonly used antibiotic that falls under the penicillin class of medications. Its brand name, Amoxil, directly associates it with the active ingredient amoxicillin, making it easily identifiable for both healthcare professionals and patients. By using brand names, pharmaceuticals often create a recognizable identity for their products, and in this case, Amoxil is the established brand name for amoxicillin specifically.

Augmentin is a brand name for a combination drug that includes amoxicillin and clavulanate potassium, which is a beta-lactamase inhibitor. This can help extend the efficacy of amoxicillin against certain bacteria that would otherwise be resistant. Cephalexin is a different antibiotic that falls under the cephalosporin class, while Azithromycin is a macrolide antibiotic. Both cephalexin and azithromycin have distinct modes of action and are used for different types of bacterial infections, making them unrelated to amoxicillin or its brand. Thus, Amoxil is unmistakably linked to amoxicillin, clarifying its role as the correct answer.
