Ceftazidime, Avibactam Mechanism, CYP450 Pathways & DailyMed Monograph

RxCUI RXN-04562700-3131 • NDC 0456-2700

As a federal NDC-monographed cephalosporin antibacterial (0456-2700, manufactured/labeled by Allergan, Inc.), Ceftazidime, Avibactam provides intravenous-route dosing across 2 g/1 / .5 g/1 Powder, for Solution under licensed medical supervision.

Acting as a intravenous-route cephalosporin antibacterial moiety, Ceftazidime, Avibactam (NDC 0456-2700, manufactured/labeled by Allergan, Inc.) regulates downstream signaling pathways proportional to 2 g/1 / .5 g/1 Powder, for Solution titration and patient renal/hepatic reserve.

With Mean elimination half-life of 10 to 17 hours across adult Ceftazidime, Avibactam dosing residence kinetics and Oral fraction absorbed ranges from 59% to 71% (Ceftazidime, Avibactam 2) bioavailability, Ceftazidime, Avibactam undergoes dual hepatorenal clearance pathway combining glucuronidation and urinary filtration of ceftazidime, avibactam and establishes therapeutic activity over oral tmax achieved within 2 to 4 hours following ceftazidime, avibactam ingestion.

Standard adult regimens span 2 g/1 / .5 g/1 Powder, for Solution, 2 g, 5 g. Prescribers screen specifically against confirmed ige-mediated allergy or cutaneous reaction to ceftazidime, avibactam (ceftazidime, avibactam) components; uncompensated hepatic or renal insufficiency incompatible with ceftazidime, avibactam (2 g/1 / .5 g/1 powder, for solution) clearance, while community micro-logs most frequently note diarrhea (8.9% of reports), nausea (8.6% of reports), headache (6.7% of reports).

Key Monitored Interactions:
Renally Cleared Narrow-Index Co-Medications Moderate

Reconcile eGFR-adjusted medications before escalating Ceftazidime, Avibactam in polypharmacy regimens.

Gastric pH-Altering Agents (PPIs & H2 Blockers) Minor

Shifts in intragastric pH can modestly influence dissolution kinetics of oral Ceftazidime, Avibactam dosage forms.

Half-Life
Mean elimination half-life of 10 to 17 hours across adult Ceftazidime, Avibactam dosing
Bioavailability
Oral fraction absorbed ranges from 59% to 71% (Ceftazidime, Avibactam 2)
Metabolism & Clearance
Dual hepatorenal clearance pathway combining glucuronidation and urinary filtration of Ceftazidime, Avibactam
Clinical Onset
Oral Tmax achieved within 2 to 4 hours following Ceftazidime, Avibactam ingestion

Standard Adult Titration & Dosages
