Randomized Controlled TrialClinical efficacy of sertraline alone and augmented with gabapentin in recently abstinent cocaine-dependent patients with depressive symptoms.
Cocaine dependence is a major public health problem with no available robustly effective pharmacotherapy. This study's aim was to determine if treatment with sertraline (SERT) or SERT plus gabapentin (GBP) improved treatment retention, depressive symptoms, and/or cocaine use. ⋯ Sertraline plus GBP may not be superior to SERT alone in delaying relapse among abstinent cocaine-dependent individuals undergoing cognitive behavioral therapy.

Randomized Controlled Trial Comparative StudyRapid tranquilization of severely agitated patients with schizophrenia spectrum disorders: a naturalistic, rater-blinded, randomized, controlled study with oral haloperidol, risperidone, and olanzapine.
Agitation is a major problem in acute schizophrenia. Only a few studies have tested antipsychotic agents in severely agitated patients, mainly because of legal issues. Furthermore, most studies were limited to the first 24 hours. We aimed to investigate the efficacy of oral haloperidol, risperidone, and olanzapine in reducing psychotic agitation in severely agitated patients with schizophrenia or schizophreniform or schizoaffective disorder over 96 hours using a prospective, randomized, rater-blinded, controlled design within a naturalistic treatment regimen. ⋯ Oral haloperidol, risperidone, and olanzapine seem to be suitable for treating acute severe psychotic agitation in schizophrenia spectrum disorders. Response to oral antipsychotics demonstrated a gender effect with poorer outcome in women throughout the study.

Randomized Controlled Trial Multicenter StudyA phase III, double-blind, placebo-controlled, flexible-dose study of levomilnacipran extended-release in patients with major depressive disorder.
Levomilnacipran (1S, 2R-milnacipran) is a potent and selective serotonin and norepinephrine reuptake inhibitor; an extended-release (ER) formulation allows for once-daily dosing. This phase III study (NCT01034462) evaluated the efficacy, the safety, and the tolerability of 40 to 120 mg/d of levomilnacipran ER versus placebo in the treatment of patients (18-80 y) with major depressive disorder. This multicenter, randomized, double-blind, placebo-controlled, parallel-group, flexible-dose study comprised a 1-week single-blind, placebo run-in period; an 8-week double-blind treatment; and a 2-week double-blind down-taper period. ⋯ Adverse events were reported in 61.8% of the placebo patients and in 81.6% of the levomilnacipran ER patients. Frequently reported adverse events (≥ 5% in levomilnacipran ER and twice the rate of placebo) were nausea, dizziness, constipation, tachycardia, urinary hesitation, hyperhidrosis, insomnia, vomiting, hypertension, and ejaculation disorder. In conclusion, there was a statistically significant difference in the score change from baseline to week 8 between levomilnacipran ER and placebo on several depression rating scales, reflecting symptomatic and functional improvement; treatment was generally well tolerated.

Randomized Controlled TrialLack of efficacy of dextromethorphan in managing alcohol withdrawal: a preliminary report of a randomized, double-blind, placebo-controlled trial.
Alcohol withdrawal syndrome is associated with increased central N-methyl-D-aspartate (NMDA) glutamate transmission. Medications that reduce glutamate release or block NMDA overactivation have shown efficacy for treating alcohol withdrawal syndrome. Dextromethorphan (DXM), a widely used antitussive drug, is a low-affinity, noncompetitive NMDA antagonist with potential neuroprotective properties. ⋯ We found that compared with placebo, DXM use was not associated with lower lorazepam doses to control alcohol withdrawal symptoms. The progression in CIWA-Ar and Obsessive-Compulsive Drinking Scale scores was also comparable between the 2 groups. Our preliminary results do not support the efficacy of high-dose DXM in reducing the need of benzodiazepines to treat withdrawal symptoms in alcohol-dependent patients.

Randomized Controlled Trialα₁-Adrenergic receptors contribute to the acute effects of 3,4-methylenedioxymethamphetamine in humans.
Preclinical studies implicate a role for α₁-noradrenergic receptors in the effects of psychostimulants, including 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy"). The present study evaluated the effects of the α₁-noradrenergic receptor antagonist doxazosin on the acute pharmacodynamic and pharmacokinetic response to MDMA in 16 healthy subjects. ⋯ Doxazosin reduced MDMA-induced elevations in blood pressure, body temperature, and moderately attenuated positive mood but enhanced tachycardia associated with MDMA. The results indicate that α₁-adrenergic receptors contribute to the acute cardiostimulant and to a minor extent possibly also to the thermogenic and euphoric effects of MDMA in humans.
