What is the name of the Monobactam antibiotic?

Aztreonam is the name of the Monobactam antibiotic. Monobactams are a class of beta-lactam antibiotics that are characterized by their monocyclic structure, which distinguishes them from other beta-lactams like penicillins and cephalosporins that have a bicyclic structure.

Aztreonam is notable for its effectiveness against aerobic gram-negative bacteria, making it particularly useful in treating infections caused by pathogens such as Pseudomonas aeruginosa. It is often used in patients with penicillin allergies due to its low cross-reactivity with other beta-lactams.

The other options represent different classes of antibiotics. Ceftazidime is a cephalosporin antibiotic, Vancomycin is a glycopeptide antibiotic often used against gram-positive bacteria, and Amoxicillin is a penicillin-type antibiotic. Understanding the specific characteristics and uses of each antibiotic class helps healthcare professionals make informed decisions when selecting antimicrobial therapies.
