Pharmacology
Cefixime is a broad-spectrum cephalosporin antibiotic of third generation for oral administration. It is a bactericidal antibiotic and is stable to hydrolysis by many beta-lactamases. Cefixime kills bacteria by interfering in the synthesis of the bacterial cell wall. It is highly active against Neisseria gonorrhoeae, Haemophilus influenzae, Moraxella catarrhalis including beta-lactamase producers, most of the Enterobacteriaceae, beta-haemolytic Streptococcus (group A & B) and Streptococcus pneumoniae. Cefixime is more active than other oral cephalosporins against Escherichia coli, Klebsiella spp, Proteus mirabilis and Serratia marcescens. Cefixime is also active against Streptococcus pyogenes. 40-50% of an oral dose is absorbed from gastro-intestinal tract, whether taken with meals or not. The plasma half-life is
usually about 3 to 4 hours and may be prolonged when there is renal impairment. About 65% of Cefixime in the circulation is bound to plasma protein. Cefixime is mainly excreted unchanged in bile and urine.
