VIVACAINE vs XARACOLL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
VIVACAINE is a local anesthetic that blocks the generation and conduction of nerve impulses by decreasing sodium ion permeability across the neuronal membrane.
XARACOLL (bupivacaine and meloxicam) is a fixed-dose combination product for local analgesia. Bupivacaine is an amide local anesthetic that blocks sodium ion channels, inhibiting nerve impulse conduction. Meloxicam is an NSAID that inhibits cyclooxygenase (COX) isoforms, reducing prostaglandin synthesis.
5-10 mL of 1% solution (50-100 mg) via submucosal infiltration or nerve block; maximum 500 mg per procedure.
Adults: Single dose of 1.3 g (two microspheres) applied intraoperatively directly to the subcutaneous tissue before wound closure.

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.
Terminal elimination half-life is approximately 2-4 hours; clinical context: methadone-like opioid, prolonged half-life in elderly, renal impairment, or hepatic impairment; requires monitoring for accumulation.
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.
Primarily hepatic metabolism followed by renal excretion of metabolites; approximately 70-80% eliminated in urine (metabolites), <15% unchanged in feces via biliary excretion.
