Randomized Controlled TrialA Randomized, Crossover Study on the Effect of Food on the Pharmacokinetic Characteristics of Morphine ARER (MorphaBond™ ER), an Abuse-Deterrent Formulation of Extended-Release Morphine.
Food can alter the pharmacokinetics of certain abuse-deterrent formulations. Morphine ARER is an oral abuse-deterrent formulation of ER morphine sulfate tablets formulated with physical and chemical properties that contribute to the abuse-deterrent aspects of the drug. This study compared the relative bioavailability of Morphine ARER in the presence and absence of food. ⋯ Inspirion Delivery Sciences, LLC.

Randomized Controlled TrialRelative Oral Bioavailability of an Abuse-deterrent, Extended-release Formulation of Morphine Versus Extended-release Morphine: A 2-period, Single-dose, Randomized Crossover Study in Healthy Subjects.
Morphine ARER is a novel oral, abuse-deterrent, extended-release (ER) formulation of morphine sulfate with physical and chemical properties that deter misuse and abuse by nonoral routes of administration. Here we evaluate the relative bioavailability of morphine ARER and extended-release morphine. ⋯ These data show that, in these subjects, morphine ARER was bioequivalent to ER morphine, a treatment for pain with well-established efficacy and safety profiles.

Randomized Controlled Trial
Pharmacokinetics of Oral and Intravenous Paracetamol (Acetaminophen) When Co-Administered with Intravenous Morphine in Healthy Adult Subjects.
Several features favor paracetamol (acetaminophen) administration by the intravenous rather than the oral route in the postoperative setting. This study compared the pharmacokinetics and bioavailability of oral and intravenous paracetamol when given with or without an opioid, morphine. ⋯ NCT02848729.

Randomized Controlled Trial
Intranasal Pharmacokinetics of Morphine ARER, a Novel Abuse-Deterrent Formulation: Results from a Randomized, Double-Blind, Four-Way Crossover Study in Nondependent, Opioid-Experienced Subjects.
To investigate the pharmacokinetics (PK) of Morphine ARER, an extended-release (ER), abuse-deterrent formulation of morphine sulfate after oral and intranasal administration. ⋯ These data suggest that Morphine ARER maintains its ER profile despite physical manipulation and intranasal administration, which may be predictive of a lower intranasal abuse potential compared with ER morphine.

Randomized Controlled TrialGabapentin enacarbil and morphine administered in combination versus alone: a double-blind, randomized, pharmacokinetic, and tolerability comparison.
Coadministration of morphine with oral gabapentin has been shown to increase plasma gabapentin concentrations. This study evaluated whether there was any interaction between gabapentin enacarbil (GEn), which is a prodrug of gabapentin, and morphine in terms of pharmacokinetics, pharmacodynamics, safety, and tolerability. ⋯ No significant pharmacokinetic interaction between the 2 drugs was seen in this study. The VAS data suggest that the potential exists for increased adverse effects when GEn and morphine are coadministered. ClinicalTrials.gov identifier: NCT01476124.
