CYCLAINE vs ISOCAINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Isocaine hydrochloride is a local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and propagation of action potentials.
0.2–0.4 mg/kg IV for induction; 0.5–1.5 mg/kg/h IV infusion for maintenance.
1-2% solution infiltrated subcutaneously or locally, maximum dose 4.5 mg/kg (with epinephrine) or 3.0 mg/kg (without epinephrine), not to exceed 300 mg.

Terminal elimination half-life: 2-4 hours in adults; prolonged with hepatic impairment.
Terminal elimination half-life is approximately 2.5 hours in healthy adults. In patients with hepatic impairment, half-life may be prolonged to 6–8 hours; in severe renal impairment, half-life may extend to 4–6 hours.
Renal: minimal (<5% unchanged); biliary/fecal: >70% as metabolites; small amount exhaled as CO2.
Renal: Approximately 90% of the dose is excreted as metabolites (primarily conjugated with glucuronic acid) in urine. Fecal: About 10% eliminated unchanged or as metabolites in feces. Biliary excretion is negligible.
