ARESTOCAINE HYDROCHLORIDE vs PARACAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Arestocaine hydrochloride is a local anesthetic of the amide type. It stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthesia.
Local anesthetic that reversibly blocks sodium channels in neuronal membranes, inhibiting nerve impulse conduction.
2-5 mg/kg intramuscularly every 60-90 minutes, not to exceed 500 mg total dose in a 12-hour period.
10-20 mg orally every 4-6 hours as needed; maximum 80 mg/day.

Terminal elimination half-life is approximately 1.5–2 hours in adults with normal hepatic and renal function; prolonged in hepatic impairment or congestive heart failure.
Clinical Note
moderateProparacaine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Proparacaine is combined with Fluticasone propionate."
Clinical Note
moderateProparacaine + Clemastine
"The risk or severity of adverse effects can be increased when Proparacaine is combined with Clemastine."
Clinical Note
moderateProparacaine + Venlafaxine
"The risk or severity of adverse effects can be increased when Proparacaine is combined with Venlafaxine."
Clinical Note
moderate2.5 hours; prolonged to 8 hours in cirrhosis due to reduced hepatic metabolism
Renal excretion of unchanged drug and metabolites; approximately 90% excreted in urine as parent compound and metabolites (60% as unchanged drug, 30% as metabolites), with less than 10% fecal elimination.
Renal: 90% (70% unchanged, 20% as paracainol glucuronide); Biliary/Fecal: 10%
