CITANEST FORTE DENTAL vs ORABLOC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Citanest Forte Dental (prilocaine and epinephrine) acts by blocking sodium channels in nerve cell membranes, inhibiting nerve impulse propagation and producing local anesthesia. Epinephrine is a vasoconstrictor that prolongs the anesthetic effect by reducing vascular uptake.
Orabloc (articaine and epinephrine) is a local anesthetic that works by blocking sodium channels in neuronal membranes, preventing nerve impulse transmission. Epinephrine is a vasoconstrictor that prolongs the anesthetic effect by reducing local blood flow.
1.7 mL (30 mg) of 4% solution for infiltration; 0.5-1.5 mg/kg for nerve block, not to exceed 2.5 mg/kg (maximum 150 mg). Administered submucosally or perineurally.
Orabloc (articaine HCl 4% with epinephrine 1:200,000): Local infiltration or nerve block. Adult: 1-7 cartridges (1.7 mL each) per procedure; max 7 mg/kg (articaine) or 500 mg (7 cartridges) per appointment.

Terminal elimination half-life is 1.6–2.0 hours in adults, prolonged in hepatic impairment or neonates.
Terminal elimination half-life: 2.5-3.5 hours; clinically, levels drop below therapeutic threshold within 6-8 hours.
Renal excretion of unchanged drug and metabolites (primarily glucuronide conjugates) accounts for approximately 95% of elimination, with less than 2% excreted in bile/feces.
Renal: 70-80% unchanged; biliary/fecal: 10-20% as metabolites.
