ALCAINE vs CYCLAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse transmission.
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.
1 to 2 drops of 0.5% solution topically to the eye, repeated as needed for anesthesia.
0.2–0.4 mg/kg IV for induction; 0.5–1.5 mg/kg/h IV infusion for maintenance.

Terminal elimination half-life: 0.4–1.2 minutes (rapid enzymatic hydrolysis by plasma esterases); clinical significance: ultra-short duration limits systemic toxicity.
Terminal elimination half-life: 2-4 hours in adults; prolonged with hepatic impairment.
Renal excretion of parent drug and metabolites: <5% unchanged.
Renal: minimal (<5% unchanged); biliary/fecal: >70% as metabolites; small amount exhaled as CO2.
