๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionIntramuscular administration results in rapid and complete absorption; intravenous administration provides immediate availability.
DistributionWidely distributed into tissues and body fluids including lungs, kidneys, bile, and cerebrospinal fluid (when meninges inflamed).
Protein BindingCefepime: ~20%; Tazobactam: ~30%
MetabolismCefepime: Minimally metabolized; Tazobactam: Metabolized to inactive metabolite.
Half-LifeCefepime: ~2 hours; Tazobactam: ~0.7-1 hour
ExcretionPrimarily renal (80-90% unchanged cefepime; tazobactam and metabolites via urine).
BioavailabilityIntramuscular: ~100%
Onset of ActionRapid (within 30 minutes for IV)
Peak Plasma TimeIV: End of infusion; IM: 1-2 hours
Duration of ActionApproximately 8-12 hours

How It Works

Cefepime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs); Tazobactam inhibits beta-lactamases, preventing degradation of cefepime.

Mechanism Steps

1Cefepime binds to penicillin-binding proteins (PBPs) on bacterial cell wall.
2Inhibition of transpeptidase enzymes prevents cross-linking of peptidoglycan chains.
3Autolytic enzymes are activated, leading to cell wall weakening and lysis.
