Cefixime, 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. Like all beta-lactam antibiotics, cefixime binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, causing the inhibition of 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 cefixime interferes with an autolysin inhibitor. Cefixime is sold under the brand name Suprax, indicated for the treatment of: Uncomplicated Urinary Tract Infections Otitis Media Pharyngitis and Tonsillitis Acute Exacerbations of Chronic Bronchitis Uncomplicated Gonorrhea (cervical/urethral)

Urinary tract infections 205 Sources: https://www.accessdata.fda.gov/drugsatfda_docs/nda/2012/203195Orig1s000Lbl.pdf	Curative	Approved 8429	SUPRAX Approved Use To reduce the development of drug resistant bacteria and maintain the effectiveness of cefixime for oral suspension USP and other antibacterial drugs, cefixime for oral suspension USP should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antimicrobial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Cefixime is a cephalosporin antibacterial indicated in the treatment of adults and pediatric patients six months of age or older with the following infections when caused by susceptible isolates of the designated bacteria: Cefixime is a cephalosporin antibacterial drug indicated for Uncomplicated Urinary Tract Infections (1.1) Otitis Media (1.2) Pharyngitis and Tonsillitis (1.3) Acute Exacerbations of Chronic Bronchitis (1.4) Uncomplicated Gonorrhea (cervical/urethral) (1.5) 1.1 Uncomplicated Urinary Tract Infections Uncomplicated Urinary Tract Infections caused by Escherichia coli and Proteus mirabilis. 1.2 Otitis Media Otitis Media caused by Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes. (Efficacy for Streptococcus pyogenes in this organ system was studied in fewer than 10 infections.) Note: For patients with otitis media caused by Streptococcus pneumoniae, overall response was approximately 10% lower for cefixime than for the comparator. Launch Date 1989
