Cefetamet Pivoxil is an oral third-generation cephalosporin antibiotic which is hydrolyzed to form the active agent, Cefetamet. It is a bactericidal antibiotic; kills bacteria by interfering with bacterial cell wall synthesis due to inhibition of Transpeptidase enzyme. Cefetamet has excellent in-vitro acitivity against the major respiratory pathogens- Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and group A b-haemolytic streptococci. It is also active against b-lactamase-producing strains of H. influenzae and M. catarrhalis. Cefetamet has marked activity against Neisseria gonorrhoeae and possesses a broad spectrum of activity against Enterobacteriaceae.

Side Effects
Most common gastrointestinal side effects may include diarrhea, nausea & vomiting. Like with other wider spectrum antibiotics, in the course of treatment with Cefetamet internal colonization from difficult Clostridium can be observed. In some cases, this microorganism or its toxin has been identified
Precaution
Cefetamet should be administered with caution to the patients who have previously manifested allergy phenomena or gastrointestinal problems. An anaphylactic reaction demands an emergency treatment. Like with other antibiotics, Cefetamet can cause the opportunistic development of non-sensitive germs (Candida, Enterococci, and difficult Clostridium); in such cases, a suitable therapy should be given. Discontinuation of the antibiotic helps to restore the normal microflora and the internal functions. In presence of difficult Clostridium cases, the treatment of choice is Vancomycin for oral use and the inhibiting drug of the peristalsis are contraindicated.
Interaction
The antacids and/or the H2-blockers do not alter the pharmacokinetic profile of Cefetamet; therefore, it can be administered in combination with these drugs. Concomitant administration with diuretic (e.g. Furosemide) does not reduce renal function.
Pregnancy & Breastfeeding use
The main preclinical studies carried out with Cefetamet have not evidenced teratogenic effects. There are no available data regarding safe use of Cefetamet during pregnancy & lactation. Therefore, it should be used during pregnancy & lactation only if the potential benefit justifies the potential risk to the fetus.
Contraindication
Cefetamet is contraindicated in patients with hypersensitivity to Cefetamet, any other cephalosporin or penicillins or any other ingredient of this formulation.
Special Warning
Renal insufficiency: In the patients with renal insufficiency, dosage modification is required.
Hepatic insufficiency: In patients with hepatic insufficiency dosage adjustment is not necessary.
Acute Overdose
In healthy volunteers, single doses of 4 gm have been administered without problems, except it causes transitory vertigo or dizziness. In case of prematurely diagnosed overdosage the gastric lavage can be useful. Then symptomatic treatment can be carried out.
