    Pharmacodynamics

    Cefdinir binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.

    Pharmacokinetics

    Absorption: Maximum plasma concentrations occur 2 to 4 hours after an oral dose of Cefdinir.

    Bioavailability: 16% to 21% for the capsules and 25% for the oral suspension

    Distribution: Widely distributed

    Protein binding: 60% to 70% bound to plasma proteins

    Metabolism: Undergoes minimal metabolism

    Excretion: Via renal excretion. Renal dysfunction reduces the clearance of Cefdinir and results in the need to reduce dosing frequency. No dosage adjustment is needed in patients with hepatic impairment

    Half-life: 2.2 ± 0.6 hrs after a 7mg/kg dose and 1.8 ± 0.4 hrs after a 14 mg/kg dose

    Indications
