DOLISHALE vs EMBEDA
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.
EMBEDA is a combination of morphine sulfate, a full opioid agonist, and naltrexone hydrochloride, an opioid antagonist. Morphine binds to mu-opioid receptors in the CNS, altering pain perception and response. Naltrexone is sequestered in the core and is released if the pellets are crushed or chewed, potentially precipitating withdrawal or blockade of morphine effects.
Adults: 200 mg orally twice daily or 400 mg orally once daily. Administer with food.
1 to 2 capsules orally every 12 hours, titrated to pain relief. Maximum daily dose: 100 mg naltrexone (equivalent to 100 mg morphine). Capsules must be swallowed whole.

Terminal elimination half-life: 12 hours (range 10-14) in adults; prolonged in renal impairment (up to 24 hours with CrCl <30 mL/min)
Morphine: 2-4 hours; naltrexone: 4-13 hours (active metabolite 6β-naltrexol: 12-18 hours). Clinically, morphine's half-life is prolonged in hepatic or renal impairment.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Renal: ~60% (morphine), ~20% (naltrexone, in urine as unchanged drug and metabolites); biliary/fecal: ~10% (morphine-3-glucuronide and other metabolites).
