DOLISHALE vs FENTORA
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 mu-opioid receptor agonist, binding to and activating opioid receptors in the brain and spinal cord, leading to analgesia and sedation.
Adults: 200 mg orally twice daily or 400 mg orally once daily. Administer with food.
For opioid-tolerant adults: 100 mcg (one tablet) placed in buccal cavity; titrate upward in increments of 100 mcg per breakthrough pain episode, with minimum 2-hour interval between doses; maximum 4 doses per day.

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 approximately 2–4 hours in adults, but can range from 2 to 6 hours depending on hepatic clearance. In elderly or hepatically impaired patients, half-life may be prolonged. The rapid initial decline is due to redistribution, and the terminal phase reflects slow elimination from deep compartments.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Primarily renal: Approximately 75% of the dose is excreted in urine as metabolites (mostly norfentanyl, despropionylfentanyl, and hydroxyfentanyl), with less than 7% as unchanged fentanyl. Fecal elimination accounts for about 9%.
