| umls-concept:C0026651 | skos:definition | MSH: Broad- spectrum beta-lactam antibiotic similar in structure to the CEPHALOSPORINS except for the substitution of an oxaazabicyclo moiety for the thiaazabicyclo moiety of certain CEPHALOSPORINS. It has been proposed especially for the meningitides because it passes the blood-brain barrier and for anaerobic infections.,NCI: A semisynthetic oxa-beta-lactam antibiotic, with antibacterial activity used mainly against gram-negative aerobic bacteria. Replacing the beta-lactam sulfur atom for an oxygen atom and the presence of the methyltetrazolethio moiety and the para-hydroxyphenylmalonyl group, increases the antibacterial activity of moxalactam. The 7-alpha-methoxy group and the para-hydroxyphenylmalonyl group increases the stability of this agent against beta-lactamases. The use of this agent has been associated with fatal bleeding events. | lld:umls |
