DOLISHALE vs ONSOLIS
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.
Onsolis (fentanyl buccal soluble film) is an opioid agonist that binds to mu-opioid receptors in the central nervous system, producing analgesia by increasing potassium conductance and inhibiting calcium channels, leading to reduced neurotransmitter release and hyperpolarization of neurons.
Adults: 200 mg orally twice daily or 400 mg orally once daily. Administer with food.
Onsolis (fentanyl buccal soluble film) is indicated for breakthrough pain in opioid-tolerant patients. The initial dose is 200 mcg placed on the buccal mucosa; titrate to effective dose in 200 mcg increments across subsequent episodes. Maximum frequency: 4 doses per day. Allow at least 2 hours between doses.

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 3-5 hours in adults, providing sustained analgesic effect with multiple daily dosing.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Primarily hepatic metabolism via glucuronidation, with approximately 70% of the dose excreted in urine as metabolites and 10-15% in feces as unchanged drug.
