Randomized Controlled Trial Comparative StudyNeuropsychiatric Safety and Efficacy of Varenicline, Bupropion, and Nicotine Patch in Smokers With Psychotic, Anxiety, and Mood Disorders in the EAGLES Trial.
Neuropsychiatric safety and relative efficacy of varenicline, bupropion, and transdermal nicotine patch (NRT) in those with psychiatric disorders are of interest. ⋯ Varenicline, bupropion, and nicotine patch are well tolerated and effective in adults with psychotic, anxiety, and mood disorders. The relative effectiveness of varenicline, bupropion, and NRT versus placebo did not vary across psychiatric diagnoses.

Randomized Controlled TrialAssessment of the Abuse Potential of Cebranopadol in Nondependent Recreational Opioid Users: A Phase 1 Randomized Controlled Study.
Cebranopadol is a nociceptin/orphanin FQ peptide/opioid receptor agonist with central antinociceptive activity. We hypothesize that this novel mechanism of action may lead to a lower risk of abuse compared with pure μ-opioid peptide receptor agonists. ⋯ These results confirm our hypothesis that cebranopadol, a nociceptin/orphanin FQ peptide/opioid receptor agonist, has lower abuse potential than hydromorphone immediate release, a pure μ-opioid peptide agonist.

Randomized Controlled TrialRandomized, Double-Blind, Placebo- and Active Comparator-Controlled Crossover Study Evaluating the Abuse Potential of the Antiepileptic Drug Lacosamide in Healthy Recreational Drug Users.
This phase 1, randomized, double-blind, placebo- and active comparator-controlled crossover study assessed the abuse potential of the antiepileptic drug, lacosamide. ⋯ These results suggest that in recreational central nervous system-depressant users, lacosamide has detectable abuse-related subjective effects, but a relatively low potential for abuse compared with alprazolam. These findings contributed toward placement of lacosamide into Schedule V of the US Controlled Substances Act.

Randomized Controlled Trial Comparative StudyAssessment of the Abuse Potential of the Orexin Receptor Antagonist, Suvorexant, Compared With Zolpidem in a Randomized Crossover Study.
Suvorexant is a dual orexin receptor antagonist approved in the United States and Japan for the treatment of insomnia at a maximum dose of 20 mg. This randomized double-blind crossover study evaluated the abuse potential of suvorexant in 36 healthy recreational polydrug users with a history of sedative and psychedelic drug use. Single doses of suvorexant (40, 80, and 150 mg: 2-7.5 × maximum dose), zolpidem (15 and 30 mg: 1.5-3 × maximum dose), and placebo were administered, with a 10-day washout between treatments. ⋯ In agreement with its classification as a schedule IV drug, suvorexant demonstrated abuse potential, compared with placebo. The abuse potential was similar to zolpidem using certain measures, but with a reduced incidence of abuse-related adverse events. Although this suggests that the overall abuse liability of suvorexant may be lower than zolpidem, the actual abuse rates will be assessed with the postmarketing experience.

Randomized Controlled Trial Multicenter StudyEfficacy, Safety, and Tolerability of RBP-7000 Once-Monthly Risperidone for the Treatment of Acute Schizophrenia: An 8-Week, Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase 3 Study.
RBP-7000 is a sustained-release formulation of risperidone for the treatment of schizophrenia, designed to be administered by once-monthly subcutaneous injection using the ATRIGEL delivery system. This study assessed the efficacy, safety, and tolerability of RBP-7000 compared with placebo in subjects with acute exacerbation of schizophrenia. Inpatients were randomly assigned to 8 weeks of double-blind treatment with subcutaneous 90 or 120 mg of RBP-7000 or placebo. ⋯ The most frequently reported treatment-emergent adverse events in RBP-7000 groups compared with placebo were somnolence, weight gain, and akathisia. The overall incidence of extrapyramidal syndrome-related effects was low and similar across groups. RBP-7000 may provide a new, long-acting alternative treatment for use in adults with acute schizophrenia.
