🔬 How This Medicine Works (Pharmacology)

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.
4Results in reversible loss of sensation in the innervated area.
