LIDOSITE TOPICAL SYSTEM KIT vs VIVACAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is an amide-type local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses.
VIVACAINE is a local anesthetic that blocks the generation and conduction of nerve impulses by decreasing sodium ion permeability across the neuronal membrane.
Apply up to 3 patches topically once daily for up to 12 hours per day. Maximum 3 patches (210 mg lidocaine) per day.
5-10 mL of 1% solution (50-100 mg) via submucosal infiltration or nerve block; maximum 500 mg per procedure.

1.5-2 hours (terminal); prolonged in hepatic dysfunction or heart failure
Terminal elimination half-life: 6–8 hours in healthy adults. In patients with hepatic impairment, half-life may be prolonged up to 12–15 hours; in severe renal impairment (CrCl <30 mL/min), half-life may extend to 10–12 hours.
Renal (80-90% as metabolites, <10% unchanged), biliary/fecal (minor, <5%)
Renal excretion of unchanged drug and metabolites accounts for approximately 85–90% of elimination, with about 10–15% excreted in feces via biliary clearance. Less than 2% of the dose is recovered unchanged in urine; the remainder is as glucuronide conjugates and other metabolites.
