BUTORPHANOL TARTRATE vs DOLISHALE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Butorphanol tartrate is a mixed agonist-antagonist opioid analgesic that exerts its effects primarily through partial agonism at the mu-opioid receptor and full agonism at the kappa-opioid receptor. This results in analgesia with a ceiling effect for respiratory depression. It also has weak antagonistic activity at the mu receptor.
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.
1-2 mg intravenously or intramuscularly every 3-4 hours as needed; alternatively, 1-2 mg intranasally as a single dose (for migraine, may repeat after 60 minutes). For patient-controlled analgesia (PCA): 0.5-1 mg intravenous bolus with lockout interval of 10-15 minutes. Epidural: 0.5-2 mg as a single dose.
Adults: 200 mg orally twice daily or 400 mg orally once daily. Administer with food.

Terminal elimination half-life is 2.5-3.5 hours (mean ~3 hours) in adults; prolonged in hepatic impairment (up to 5-6 hours) and renal impairment (variable, may increase).
Terminal elimination half-life: 12 hours (range 10-14) in adults; prolonged in renal impairment (up to 24 hours with CrCl <30 mL/min)
Primarily hepatic metabolism to inactive metabolites; renal excretion accounts for approximately 70-80% of elimination (mostly metabolites), with 15-20% via feces (biliary). Less than 5% excreted unchanged in urine.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
