Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ALPHACAINE is a local anesthetic that binds to the intracellular portion of voltage-gated sodium channels, blocking sodium influx and preventing depolarization and conduction of nerve impulses.
Lidocaine is an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses.
10-20 mg IM or IV every 4-6 hours as needed; maximum 80 mg/day.
Adult: 5-25 mL (250-1250 mg lidocaine) of 5% lidocaine with glucose 7.5% solution, administered by caudal or lumbar epidural injection, single dose. Max total dose: 1250 mg.

Terminal elimination half-life: 3.5-5.0 hours (prolonged in hepatic impairment; requires dose adjustment in Child-Pugh B or C).
1.5-2 hours (terminal); prolonged in heart failure, hepatic disease, or elderly; neonates 3-6 hours due to immature hepatic function.
Renal: ~60-70% unchanged; Hepatic metabolism: ~20-30% via CYP3A4 and CYP2C9; Fecal: <10%.
Hepatic metabolism (90% N-dealkylation by CYP1A2/CYP3A4 to monoethylglycinexylidide and glycinexylidide); renal excretion of metabolites and parent drug (<10% unchanged); <1% biliary/fecal.
