๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionIntramuscular administration results in rapid and complete absorption; intravenous administration provides immediate systemic availability.
DistributionWidely distributed into body tissues and fluids including cerebrospinal fluid (with inflamed meninges), bile, sputum, and pleural fluid.
Protein BindingApproximately 56% bound to plasma proteins.
MetabolismMetabolized primarily by hydrolysis of the beta-lactam ring to inactive metabolites.
Half-LifeApproximately 1.7 hours in patients with normal renal function; prolonged in renal impairment.
ExcretionPrimarily excreted unchanged in urine (60-70%) via glomerular filtration and tubular secretion; small amount in feces.
Bioavailability100% (intravenous); approximately 100% (intramuscular).
Onset of ActionRapid; within 30 minutes after intravenous administration.
Peak Plasma TimeIntravenous: immediately after infusion; intramuscular: 1 hour.
Duration of ActionApproximately 6-8 hours depending on renal function.

How It Works

Inhibits bacterial cell wall synthesis by binding to penicillin-binding protein 3 (PBP3), leading to cell lysis and death.

Mechanism Steps

1Aztreonam binds to penicillin-binding protein 3 (PBP3) on the inner membrane of Gram-negative bacteria.
2Inhibition of PBP3 prevents transpeptidation, a key step in peptidoglycan cross-linking.
3Disruption of cell wall synthesis leads to osmotic instability and bacterial cell lysis.
