aztreonam - Medications

AZACTAM ® (aztreonam for injection, USP) contains the active ingredient aztreonam, a monobactam. It was originally isolated from Chromobacterium violaceum . It is a synthetic bactericidal antibiotic. The monobactams, having a unique monocyclic beta-lactam nucleus, are structurally different from other beta-lactam antibiotics (eg, penicillins, cephalosporins, cephamycins). The sulfonic acid substituent in the 1-position of the ring activates the beta-lactam moiety; an aminothiazolyl oxime side chain in the 3-position and a methyl group in the 4-position confer the specific antibacterial spectrum and beta-lactamase stability. Aztreonam is designated chemically as (Z)-2-[[[(2-amino-4-thiazolyl)[[(2S,3S)-2-methyl-4-oxo-1-sulfo-3-azetidinyl]carbamoyl]methylene]amino]oxy]-2-methylpropionic acid. Structural formula: C 13 H 17 N 5 O 8 S 2 MW 435.44 AZACTAM is a sterile, nonpyrogenic, sodium-free, white powder containing 0.78 grams arginine per 1 gram of aztreonam and 1.54 grams arginine per 2 grams of aztreonam. Following constitution, the product is for intramuscular or intravenous use. Aqueous solutions of the product have a pH in the range of 4.5 to 7.5. aztreonam chemical structure
