Zetaro Injection 600 mg contains Ceftaroline Fosamil, a fifth-generation cephalosporin antibiotic designed to treat a broad spectrum of bacterial infections. It is particularly effective against methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Gram-positive pathogens. Zetaro is administered intravenously for rapid and effective management of serious infections such as community-acquired pneumonia (CAP), skin and soft tissue infections (SSTIs), and other complicated bacterial infections.

Therapeutic Class

Fifth-Generation Cephalosporin Antibiotic

Indications

Zetaro Injection 600 mg is indicated for the treatment of:

• Acute Bacterial Skin and Skin Structure Infections (ABSSSI): Caused by susceptible Gram-positive organisms including Staphylococcus aureus (including MRSA) and Streptococcus pyogenes.

• Community-Acquired Pneumonia (CAP): Caused by susceptible strains of Streptococcus pneumoniae, Haemophilus influenzae, and other susceptible bacteria.

• Other Severe Infections: Including bacteremia associated with the above conditions when caused by susceptible organisms.

Zetaro is particularly valuable for patients with infections unresponsive to other antibiotics or infections caused by resistant organisms.

Pharmacology

Ceftaroline Fosamil is a prodrug that is rapidly converted to its active metabolite, ceftaroline, in the body. It exerts bactericidal activity by binding to penicillin-binding proteins (PBPs), inhibiting bacterial cell wall synthesis, and causing cell lysis.

Ceftaroline has enhanced activity against MRSA due to its high affinity for PBP2a, the altered penicillin-binding protein responsible for methicillin resistance. It also retains potent activity against a broad range of Gram-positive and some Gram-negative pathogens.

Zetaro is administered intravenously, ensuring rapid plasma concentrations and effective bacterial killing in serious infections.

Dosage and Administration

• Adults: 600 mg of Zetaro is administered via intravenous infusion over 60 minutes every 12 hours.

• Renal Impairment: Dose adjustments are recommended for patients with moderate to severe renal impairment (creatinine clearance <50 mL/min).

• Pediatric Use: Safety and efficacy have been established for children over 2 months; dosing should be calculated based on body weight and renal function.

• Elderly: No dosage adjustment is required solely based on age; renal function should be monitored.

Infusion should be prepared according to standard aseptic techniques, and the solution should be administered immediately or stored as per stability guidelines.

Drug Interactions

• No significant drug interactions reported, but co-administration with nephrotoxic drugs may increase risk of renal toxicity.

• Concurrent use with anticoagulants may require monitoring due to potential alterations in coagulation parameters.

Contraindications

• Hypersensitivity to ceftaroline, other cephalosporins, or beta-lactam antibiotics

• History of severe allergic reactions to penicillins

Side Effects

Common:

• Gastrointestinal disturbances: diarrhea, nausea, vomiting

• Headache

• Rash or mild hypersensitivity reactions

Less common but serious:

• Severe hypersensitivity reactions (anaphylaxis)

• Clostridium difficile-associated diarrhea

• Neutropenia, eosinophilia, or thrombocytopenia with prolonged therapy

• Elevated liver enzymes

Precautions and Warnings

• Monitor renal function in patients with impaired kidney function

• Observe for signs of hypersensitivity, particularly in patients with a history of penicillin allergy

• Use with caution in patients with a history of gastrointestinal disease, particularly colitis

• Prolonged use may result in overgrowth of non-susceptible organisms

Pregnancy and Lactation

• Pregnancy: Use only if clearly needed; no adequate human studies are available

• Lactation: Unknown if excreted in breast milk; use caution or consider alternative therapy

Storage Conditions

Store below 25°C in a dry place, protected from light. Reconstituted solution should be used immediately or stored as recommended. Keep out of reach of children.

Mode of Action

Ceftaroline, the active metabolite of Zetaro, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins, including PBP2a in MRSA. This results in bacterial cell lysis and rapid bactericidal activity against both Gram-positive and selected Gram-negative pathogens.
