DOLISHALE vs ULTIVA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DOLISHALE is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane, enhancing serotonin neurotransmission.
Selective mu-opioid receptor agonist with rapid onset and short duration of action; produces analgesia without significant histamine release.
Adults: 200 mg orally twice daily or 400 mg orally once daily. Administer with food.
IV bolus: 1 mcg/kg over 30-60 seconds, then continuous IV infusion: 0.25-1 mcg/kg/min for intraoperative analgesia. For general anesthesia induction: 0.5-1 mcg/kg IV bolus; maintenance: 0.25-1 mcg/kg/min IV infusion.

Terminal elimination half-life: 12 hours (range 10-14) in adults; prolonged in renal impairment (up to 24 hours with CrCl <30 mL/min)
Terminal elimination half-life is 3-10 minutes (context-sensitive half-time is 3-4 minutes independent of infusion duration due to rapid ester hydrolysis). Clinically, recovery is rapid and predictable even after prolonged infusions, with full recovery within 5-10 minutes of discontinuation.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Remifentanil is metabolized by non-specific blood and tissue esterases to a virtually inactive metabolite (remifentanil acid, 1/4600 potency). Renal excretion accounts for approximately 90% of the metabolite; fecal elimination is minimal (<5%).
