DURACLON vs LUCEMYRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Alpha-2 adrenergic receptor agonist in the pontine locus coeruleus, reducing central sympathetic outflow and norepinephrine release, thereby decreasing blood pressure, heart rate, and opioid withdrawal symptoms.
LUCEMYRA (lofexidine) is a central alpha-2 adrenergic agonist that reduces the release of norepinephrine in the brain, thereby alleviating opioid withdrawal symptoms.
Epidural or intrathecal: 30 mcg/hour continuous epidural infusion (300 mcg/mL concentration) or 100-600 mcg/day intrathecal infusion as part of multimodal analgesia; not for bolus administration. Intravenous: 0.3-2.4 mcg/kg/hour continuous infusion for ICU sedation (off-label use).
18 mg orally 5-6 times daily (maximum 108 mg/day) for 7-14 days then tapered over 4-6 weeks.

Terminal elimination half-life is 12-16 hours in patients with normal renal function. In renal impairment, it may extend to 30-40 hours, necessitating dose adjustment. The half-life supports twice-daily dosing for epidural formulations.
Terminal half-life approximately 5-6 hours; no clinically significant accumulation with twice-daily dosing.
Clonidine (DURACLON) is primarily excreted renally. Approximately 40-60% is excreted unchanged in urine, with the remainder as metabolites (mainly p-hydroxyclonidine). Fecal excretion accounts for ~20% of elimination; biliary excretion is minimal (<5%).
Renal: 63% as unchanged drug; fecal: 27% (mostly unchanged); biliary: minimal (<5%).
