Exephin 500 mg/vial is a third-generation cephalosporin antibiotic designed for the treatment and prevention of a wide range of bacterial infections. With potent bactericidal activity, Exephin disrupts the synthesis of bacterial cell walls, effectively combating both Gram-positive and Gram-negative organisms. It is particularly valued for its broad-spectrum coverage, stability against beta-lactamases, and long plasma half-life, which allows for convenient once- or twice-daily dosing in most patients.

Exephin 500 mg/vial is suitable for treating serious infections in adults and children, including respiratory, urinary, skin, bone, and systemic infections, as well as for perioperative prophylaxis to prevent postoperative infections.

Third-generation Cephalosporin

Pharmacology

Exephin 500 mg/vial is a parenteral cephalosporin with broad-spectrum bactericidal activity. Its mechanism involves inhibiting bacterial cell wall synthesis, which leads to bacterial cell death. Key pharmacological features include:

• High stability against beta-lactamases

• Long plasma half-life (6–9 hours), allowing convenient dosing

• Protein binding: ~95%

• Excretion: 40–65% unchanged in urine; remainder in bile and feces

Exephin is not metabolized in the body and achieves high concentrations in blood, urine, and tissues, making it highly effective against systemic and localized infections.

Dosage and Administration

Adults:

• General infections: 1–2 g IV or IM once daily (or divided into two doses); max 4 g/day

• Uncomplicated gonococcal infections: 250 mg IM single dose

• Meningitis: 100 mg/kg IV or IM daily or divided doses; max 4 g/day

Administration:

• IM injections should be reconstituted with Lidocaine HCl 1%

• IV injections should be reconstituted with water for injection, administered over 2–4 minutes or infused over 30 minutes

• Patient tolerance should be checked with a test dose before full administration

Duration: Therapy should continue ≥2 days after symptom resolution, typically 4–14 days; prolonged treatment may be needed for complicated infections.
