DOLISHALE vs DURAGESIC-75
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.
Fentanyl is a potent opioid agonist primarily at the mu-opioid receptor, exerting its analgesic effects by mimicking endogenous endorphins and enkephalins to activate G-protein-coupled inwardly rectifying potassium channels, leading to hyperpolarization and reduced neuronal excitability in pain pathways.
Adults: 200 mg orally twice daily or 400 mg orally once daily. Administer with food.
Adults: Apply one 75 mcg/hr transdermal patch every 72 hours. Start with lower dose in opioid-naive patients.

Terminal elimination half-life: 12 hours (range 10-14) in adults; prolonged in renal impairment (up to 24 hours with CrCl <30 mL/min)

Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
