LUCEMYRA

Absorption LUCEMYRA is well absorbed and achieves peak plasma concentration 3 to 5 hours after administration of a single dose. LUCEMYRA shows approximately dose-proportional pharmacokinetics. Administration of LUCEMYRA with food does not alter its pharmacokinetics. The absolute bioavailability of a single oral LUCEMYRA dose (0.36 mg in solution) compared with an intravenous infusion (0.2 mg infused for 200 minutes) was 72%. Mean LUCEMYRA C max after the oral dose and intravenous infusion was 0....

Two randomized, double-blind, placebo-controlled trials supported the efficacy of LUCEMYRA.

Study 1NCT01863186 Study 1 was a 2-part efficacy, safety, and dose-response study conducted in the United States in patients meeting DSM-IV criteria for opioid dependence who were physically dependent on short-acting opioids (e.g., heroin, hydrocodone, oxycodone). The first part of the study was an inpatient, randomized, double-blind, placebo-controlled design consisting of 7 days of inpatient treatment (Days 1 – 7) with LUCEMYRA 2.16 mg total daily dose (0.54 mg 4 times daily) (n=229), LUCEMYRA 2.88 ...

The following serious adverse reactions are described elsewhere in labeling: Hypotension, Bradycardia, and Syncope [see Warnings and Precautions (5.1) ] QT Prolongation [see Warnings and Precautions (5.2) ] Central Nervous System Depression [see Warnings and Precautions (5.3) ] Opioid Overdose [see Warnings and Precautions (5.4) ] Discontinuation Symptoms [see Warnings and Precautions (5.5) ] Most common adverse reactions (incidence ≥ 10% and notably more frequent than placebo) are orthostatic h...

None. None. ( 4 )

Risk of Hypotension, Bradycardia, and Syncope : May cause a decrease in blood pressure, a decrease in pulse, and syncope. Monitor vital signs before dosing and advise patients on how to minimize the risk of these cardiovascular effects and manage symptoms, should they occur. Monitor symptoms related to bradycardia and orthostasis. When using in outpatients, ensure that patients are capable of self-monitoring for signs and symptoms. Avoid use in patients with severe coronary insufficiency, recent...

7 DRUG INTERACTIONS Methadone : Methadone and LUCEMYRA both prolong the QT interval. ECG monitoring is recommended when used concomitantly. ( 7.1 ) Oral Naltrexone : Concomitant use may reduce efficacy of oral naltrexone. ( 7.2 ) CYP2D6 Inhibitors : Concomitant use of paroxetine resulted in increased plasma levels of LUCEMYRA. Monitor for symptoms of orthostasis and bradycardia with concomitant us...
