Description:
Mechanism of Action: Cefprozil is a semi-synthetic, broad-spectrum 2nd generation cephalosporin. It acts by inhibiting the bacterial cell wall synthesis by binding to 1 or more of penicillin-binding proteins (PBPs) which interrupts the final transpeptidation step of peptidoglycan synthesis leading to bacterial cell lysis and death.
Pharmacokinetics:
Absorption: Well absorbed from the gastrointestinal tract. Bioavailability: 90-95%. Time to peak plasma concentration: 1.5 hours (fasting).
Distribution: Widely distributed in various body tissues and fluids. Enters breast milk. Volume of distribution: 0.23 L/kg. Plasma protein binding: Approx 36%.
Excretion: Via urine (approx 60%, as unchanged drug). Elimination half-life: 1-3 hours.
