CYCLAINE vs XYLOCAINE VISCOUS
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.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels, inhibiting nerve impulse propagation and reducing pain sensation.
0.2–0.4 mg/kg IV for induction; 0.5–1.5 mg/kg/h IV infusion for maintenance.
Adults: 5-15 mL orally (or swish and spit) 4-6 times daily, not to exceed 4 doses in 12 hours or 30 mL in 12 hours.

Terminal elimination half-life: 2-4 hours in adults; prolonged with hepatic impairment.
Terminal elimination half-life: 1.5-2 hours in adults; prolonged in hepatic impairment or heart failure (up to 6-8 hours). In neonates, half-life may be 3-6 hours due to immature metabolism.
Renal: minimal (<5% unchanged); biliary/fecal: >70% as metabolites; small amount exhaled as CO2.
Renal excretion of metabolites: ~90%. Unchanged drug: <10%. Biliary/fecal: minor.
