Latamoxef
Accession Number
DB04570
Description

Latamoxef is a 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.

Pharmacodynamics

Latamoxef works by inhibiting bacterial cell wall biosynthesis.

Mechanism of action

Penicillins acylate the penicillin-sensitive transpeptidase C-terminal domain (the penicillin-binding protein) by opening the lactam ring. This inactivation of the enzyme prevents the formation of a cross-link of two linear peptidoglycan strands, inhibiting the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that amoxicllin interferes with an autolysin inhibitor.

Toxicity

Latamoxef produces potentially life-threatening effects which include Bleeding, Hypothrombinemia, Platelet dysfunctioning. which are responsible for the discontinuation of Latamoxef therapy. The symptomatic adverse reactions produced by Latamoxef are more or less tolerable and if they become severe, they can be treated symptomatically, these include Diarrhea, Skin rashes, Hematuria, Hyperuricemia, Pyuria, Raised serum creatinine.
