Cefspan - General Information:
Cefspan, an antibiotic, is a third-generation cephalosporin like ceftriaxone and cefotaxime. Cefspan 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.

The antibacterial effect of cefixime results from inhibition of mucopeptide synthesis in the bacterial cell wall.

Cefspan for patients
Cefixime is a cephalosporin antibiotic used to treat bacterial infections. Take at regular intervals and complete the entire course of therapy. Do not take this medication if you are allergic to any type of penicillin or cephalosporin. Notify your physician if you are pregnant or nursing. This antibiotic may decrease the effectiveness of birth control pills; use another form of birth control while taking this medication. Shake the suspension well before each use and store it in the refrigerator. May cause nausea, vomiting or diarrhea; notify your physician if these occur. Take with food or milk to avoid stomach upset. Cefixime may cause a false-positive reaction for nonspecific urine glucose tests in patients with diabetes. This medication does not interfere with enzyme-based urine glucose tests.

Cefspan Interactions
Carbamazepine: Elevated carbamazepine levels have been reported in postmarketing experience when SUPRAX is administered concomitantly. Drug monitoring may be of assistance in detecting alterations in carbamazepine plasma concentrations.

Warfarin and Anticoagulants: Increased prothrombin time, with or without clinical bleeding, has been reported when cefixime is administered concomitantly.

Drug/Laboratory Test Interactions

A false-positive reaction for ketones in the urine may occur with tests using nitroprusside but not with those using nitroferricyanide.

The administration of SUPRAX may result in a false-positive reaction for glucose in the urine using ClinitestÒ**, Benedictís solution, or Fehlingís solution. It is recommended that glucose tests based on enzymatic glucose oxidase reactions (such as Clinistix®** or Tes-TapeÒ**) be used. A false-positive direct Coombs test has been reported during treatment with other cephalosporin antibiotics; therefore, it should be recognized that a positive Coombs test may be due to the drug.

Cefspan Contraindications
SUPRAXÒ is contraindicated in patients with known allergy to the cephalosporin group of antibiotics.

Additional information about Cefspan
Cefspan Indication: For use in the treatment of the following infections when caused by susceptible strains of the designated microorganisms: (1) uncomplicated urinary tract infections caused by Escherichia coli and Proteus mirabilis, (2) otitis media caused by Haemophilus influenzae (beta-lactamase positive and negative strains), Moraxella catarrhalis (most of which are beta-lactamase positive), and S. pyogenes, (3) pharyngitis and tonsillitis caused by S. pyogenes, (4) acute bronchitis and acute exacerbations of chronic bronchitis caused by Streptococcus pneumoniae and Haemophilus influenzae (beta-lactamase positive and negative strains), and (5) uncomplicated gonorrhea (cervical/urethral) caused by Neisseria gonorrhoeae (penicillinase- and non-penicillinase-producing strains).
Mechanism Of Action: 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.
Drug Interactions: Probenecid Probenecid increases the antibiotic's level
Food Interactions: Preferably on an empty stomach, rate of absorption is decreased but extenet of absorption remains the same: not really problematic.
Generic Name: Cefixime
Synonyms: Cefixima [Spanish]; Cefixime Anhydrous; Cefiximum [Latin]; Cefixim
Drug Category: Anti-Bacterial Agents; Cephalosporins
Drug Type: Small Molecule; Approved
Other Brand Names containing Cefixime: CFIX; Cefixoral; Cefspan; Cephoral; Oroken; Suprax; Unixime;
Absorption: About 40%-50% absorbed orally whether administered with or without food, however, time to maximal absorption is increased approximately 0.8 hours when administered with food.
Toxicity (Overdose): Symptoms of overdose include blood in the urine, diarrhea, nausea, upper abdominal pain, and vomiting.
Protein Binding: 65% (concentration independent)
Biotransformation: Hepatic. Approximately 50% of the absorbed dose is excreted unchanged in the urine in 24 hours.
Half Life: 3-4 hours (may range up to 9 hours). In severe renal impairment (5 to 20 mL/min creatinine clearance), the half-life increased to an average of 11.5 hours.
