Cefixime Trihydrate Tablet
Cefixime Trihydrate , an antibiotic, is a third-generation cephalosporin like ceftriaxone and cefotaxime. Cefixime is highly stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillins and some cephalosporins due to the presence of beta- lactamases, may be susceptible to cefixime. The antibacterial effect of cefixime results from inhibition of mucopeptide synthesis in the bacterial cell wall.
â Urinary tract infections
â Infections caused by susceptible organisms.
Mechanism of Action:
Cefixime is an orally active 3rd generation cephalosporin which exerts its bactericidal action against both gram positive & gram negative organisms by inhibiting bacterial cell wall synthesis. Cefixime inhibits transpeptidase & thus prevents cross linking of bacterial cell wall. Transpeptidase & associated proteins constitute various types of specific binding proteins which have affinity for cephalosporins like Cefixime. It is highly active against enterobacteriaceae, Haemophilus influenzae, Streptococcus pyogens & Streptococcus pneumonia &many beta lactamase producing bacteria.
