🔬 Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionRapidly absorbed from the injection site; systemic absorption depends on dose, concentration, and vascularity of the site.

DistributionWidely distributed; highly bound to tissues; crosses the blood-brain barrier and placenta.

Protein BindingApproximately 95% bound to alpha-1-acid glycoprotein.

MetabolismPrimarily hepatic via CYP3A4 and CYP1A2 to pipecoloxylidine and desbutylbupivacaine.

Half-Life2.7 to 3.4 hours in adults; prolonged in neonates and hepatic impairment.

ExcretionRenal excretion of metabolites; less than 5% unchanged.

BioavailabilityNot applicable (administered parenterally); systemic absorption depends on route.

Onset of Action5 to 10 minutes for spinal anesthesia.

Peak Plasma Time15 to 30 minutes after injection.

Duration of Action2 to 4 hours for spinal anesthesia; longer with epinephrine.

How It Works

Blocks sodium channels in nerve cell membranes, inhibiting nerve impulse conduction.

Mechanism Steps

1Bupivacaine binds to the intracellular portion of voltage-gated sodium channels.

2Inhibits sodium influx, preventing depolarization of the nerve membrane.

3Blocks propagation of action potentials along the nerve axon.
