Third generation Cephalosporins

Cetaxone 500 mg/vial is a 3rd generation broad-spectrum parenteral cephalosporin antibiotic. It has potent bactericidal activity against a wide range of Gram-positive and Gram-negative organisms. Like other cephalosporins and penicillins, Cetaxone 500 mg/vial kills bacteria by interfering with the synthesis of the bacterial cell wall. Cetaxone 500 mg/vial has a high degree of stability in the presence of beta lactamases. A remarkable feature of Cetaxone 500 mg/vial is its relatively long plasma elimination half-life of about 6 to 9 hours, which makes single or once-daily dosage of the drug appropriate for most patients. Cetaxone 500 mg/vial is not metabolized in the body. About 40-65% of a dose of Cetaxone 500 mg/vial is excreted unchanged in the urine; the remainder is excreted in the bile and ultimately found in the feces as unchanged drug and microbiologically inactive compound. The drug is highly protein bound (95%).

As with other cephalosporins, anaphylactic shock cannot be ruled out even if a thorough patient history is taken. Anaphylactic shock requires immediate countermeasures such as intravenous epinephrine followed by a glucocorticoid. In rare cases, shadows suggesting sludge have been detected by sonograms of the gallbladder. This condition was reversible on discontinuation or completion of Cetaxone 500 mg/vial therapy. Even if such findings are associated with pain, conservative, nonsurgical management is recommended. During prolonged treatment the blood picture should be checked at regular intervals.
