DOLISHALE vs DURAMORPH PF
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.
Morphine is a full opioid agonist that primarily acts on mu-opioid receptors in the central nervous system to produce analgesia, euphoria, and sedation. It also interacts with kappa and delta receptors. It inhibits ascending pain pathways and alters pain perception and response.
Adults: 200 mg orally twice daily or 400 mg orally once daily. Administer with food.
0.8 to 10 mg via epidural injection as a single dose or via continuous epidural infusion at 0.1 to 1 mg/hour. For intrathecal use: 0.2 to 1 mg as a single dose. Intravenous: 2 to 10 mg for analgesia every 2-4 hours as needed.

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 of morphine is approximately 2-4 hours in adults. In neonates and elderly, half-life may be prolonged (up to 4.5-6.5 hours). Context: half-life may be extended in renal impairment due to accumulation of active metabolites.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Primarily renal (approximately 90% as morphine-3-glucuronide and morphine-6-glucuronide, with 10% as unchanged morphine). Biliary/fecal excretion accounts for less than 10%.
