USES
Ceftaroline is intravenous in its route of administration and its dose and course will depend on the etiology and severity of infection being treated as well as the general condition of the patient.
For adults: For adults, the usual dosage is 600 mg of Ceftaroline intravenously administered every 12 hours. The duration of treatment will depend on the infection; however, most treatments usually range from 5 to 14 days, depending on the severity of the condition.
For pediatric patients: For pediatric patients aged more than or equal to 2 months, Ceftaroline could be administered. Dosages are determined with regards to the weight and the disease severity of a child.
Ceftaroline infusion is administered to the patients through the vein with an action time of approximately 2 hours. Dosage intensity, along with frequency of the doses, must always be provided by the physician or any prescribing healthcare giver.
WORKING
Ceftaroline works by inhibiting bacterial cell wall synthesis. Like all cephalosporins, it targets penicillin-binding proteins (PBPs) that are essential for the formation of the bacterial cell wall. By binding to these proteins, Ceftaroline prevents bacteria from building their protective cell walls, causing them to break apart and die.
What makes Ceftaroline different from other cephalosporins is its increased activity against MRSA. This is due to its specific binding affinity for the altered PBP2a protein in MRSA. The PBP2a protein is associated with the bacteria’s resistance to methicillin and other beta-lactam antibiotics. Because of its ability to bind to this protein and interfere with cell wall synthesis, Ceftaroline is an effective option for treating MRSA, which has become a pathogen that is increasingly resistant to traditional antibiotics.
SIDE EFFECTS
While Ceftaroline is generally well tolerated, it can cause side effects, including:
Gastrointestinal symptoms: Nausea, vomiting, diarrhea, and abdominal pain are common side effects. These are generally mild and may resolve on their own after a few days of treatment.
Hypersensitivity reactions: Some patients may develop allergic conditions, such as rashes, itching, or may be more severe, even anaphylaxis. Patients with a history of allergy to penicillins or cephalosporins should exercise careful use of Ceftaroline.
Hematologic effects: Infrequently, Ceftaroline affects blood cell counts, either leukopenia or thrombocytopenia. Blood work may be monitored during lengthy treatment.
Liver enzyme abnormalities: Ceftaroline may cause liver enzyme elevations, indicating possible liver dysfunction. Liver function tests may be performed during treatment, especially in patients with pre-existing liver conditions.
Clostridium difficile-associated diarrhea: Like other antibiotics, Ceftaroline may alter the normal balance of gut bacteria, increasing the risk of Clostridium difficile infection, which can cause severe diarrhea and colitis.
WARNINGS
Allergic reactions: Patients who are already known allergic to cephalosporins or penicillins should exercise caution as cross-reactivity may be expected. There is an infrequent incidence of more severe allergic reaction such as anaphylaxis.
Renal impairment: Dosage adjustments will be needed in patients who suffer renal impairment. Monitoring of the kidney functions will be mandatory, particularly in patients who are suffering from pre-existing kidney diseases.
Pregnancy and breastfeeding: Ceftaroline is classified as a pregnancy category B drug, indicating that it is generally considered safe for use during pregnancy, but should only be used when necessary. It is also excreted in breast milk, so caution is advised for nursing mothers.
Superinfection: Prolonged use of Ceftaroline, or any antibiotic, can lead to the development of superinfections caused by resistant bacteria or fungi. If new infections develop during treatment, the healthcare provider may need to adjust the treatment regimen.
INTERACTIONS
Ceftaroline can interact with other drugs to either reduce its efficacy or increase the risk of adverse effects. Some important drug interactions include:
Probenecid: This is a medication for treating gout. Probenecid inhibits the renal excretion of Ceftaroline, thereby increasing the blood level of the antibiotic. In such cases, the blood level of Ceftaroline may increase significantly in the body, potentially causing increased side effects.
Other antibacterial agents: Ceftaroline is often used with another antibiotic to provide greater antibacterial coverage. The important point is to note when the other antibiotics would present possible interactions that can potentially influence bacterial resistance and therefore affect the efficacy.
Live vaccines: There is no direct contraindication between Ceftaroline and vaccines, but patients treated with antibiotics may have attenuated responses to live vaccines due to the effects of the antibiotic on the immune system. It is preferable to avoid vaccination with live vaccines during antibiotic treatment unless instructed otherwise by a healthcare provider.
DOSAGE
The usual adult dose of Ceftaroline is 600 mg, administered intravenously every 12 hours. The duration of treatment depends on the type and severity of the infection being treated but typically ranges from 5 to 14 days. For pediatric patients, the dosage is based on weight and infection severity, and the healthcare provider will determine the appropriate dosage.
PRESCRIPTION
Ceftaroline is a prescription-only drug, meaning that only a healthcare provider can prescribe it. It is mainly reserved for serious infections, especially those caused by resistant organisms such as MRSA. Because it is an intravenous drug, it is usually administered in the hospital or clinical setting and, therefore, not as good for outpatient use without appropriate follow-up care.
