AVIBACTAM
Background and Date of Approval
Avibactam is a non β-lactam β-lactamase inhibitor developed to address antibiotic resistance in bacterial infections. Approved by the FDA in February 2015, it is used in combination with other antibiotics to treat complicated infections. Clinical trials demonstrated its activity against multidrug-resistant organisms, particularly gram-negative bacteria. Avibactam has completed pivotal Phase III trials, demonstrating its ability to restore the activity of β-lactam antibiotics against resistant pathogens.
Uses
Avibactam is FDA-approved for use in combination with other antibiotics to treat: Complicated intra-abdominal infections (cIAI) Complicated urinary tract infections (cUTI), including pyelonephritis Hospital-acquired bacterial pneumonia (HABP) Ventilator-associated bacterial pneumonia (VABP)
Side Effects
Common Side Effects Diarrhea Nausea and vomiting Headache Rash or itching at the injection site Serious Side Effects Anaphylaxis (severe allergic reactions) Clostridioides difficile-associated diarrhea Seizures (rare, but significant) Elevated liver enzymes (indicating liver stress)
Warnings
Severe Allergic Reactions: Avoid use in individuals with a history of hypersensitivity to β-lactam antibiotics. Renal Impairment: Dosage adjustments are critical for patients with compromised kidney function. Seizures: Risk increases in patients with central nervous system disorders. Drug Interactions: Avoid concurrent use with other nephrotoxic agents. Pregnancy and Lactation: Use only if clearly needed and under medical supervision.
Precautions
Before administering this medication, it is essential to assess the patientâs medical history, including any known allergies to penicillin or cephalosporin antibiotics. Regular renal function monitoring is advised, as improper clearance can increase toxicity risks. Administer the drug under strict medical supervision, ensuring aseptic techniques for intravenous infusion. Pregnant and breastfeeding individuals should consult a healthcare provider to weigh potential risks and benefits.
Word of Advice
Avibactam must be used only under healthcare provider supervision. Maintain adequate hydration throughout treatment and report any unusual symptoms promptly, including severe diarrhoea or allergic reactions. Do not self-medicate or change dosages without consulting your doctor. Patients with existing kidney conditions require regular renal monitoring during therapy. Complete the full prescribed course to prevent resistance.
