ALPHACAINE vs CYCLAINE
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.
Cyclaine is a local anesthetic that reversibly blocks nerve conduction by decreasing the permeability of the neuronal membrane to sodium ions, thereby stabilizing the membrane and preventing the initiation and transmission of electrical impulses.
10-20 mg IM or IV every 4-6 hours as needed; maximum 80 mg/day.
0.2–0.4 mg/kg IV for induction; 0.5–1.5 mg/kg/h IV infusion for maintenance.

Terminal elimination half-life: 3.5-5.0 hours (prolonged in hepatic impairment; requires dose adjustment in Child-Pugh B or C).
Terminal elimination half-life: 2-4 hours in adults; prolonged with hepatic impairment.
Renal: ~60-70% unchanged; Hepatic metabolism: ~20-30% via CYP3A4 and CYP2C9; Fecal: <10%.
Renal: minimal (<5% unchanged); biliary/fecal: >70% as metabolites; small amount exhaled as CO2.
