This randomized, double-blind, placebo-controlled, parallel-group study was to determine the pharmacokinetic characteristics, safety, and tolerability of multiple doses of inhaled loxapine aerosol in subjects on a stable, oral, chronic antipsychotic regimen. Loxapine was delivered by means of a unique thermally generated aerosol comprising drug particles of a size designed for deep lung delivery and absorption. Thirty-two subjects were randomized 1:1:1:1 to receive inhaled loxapine (total doses of 15, 20, or 30 mg) or inhaled placebo administered in 3 divided doses, given 4 hours apart.

Effect of steady-state faldaprevir on the pharmacokinetics of steady-state methadone and buprenorphine-naloxone in subjects receiving stable addiction management therapy.

The effects of steady-state faldaprevir on the safety, pharmacokinetics, and pharmacodynamics of steady-state methadone and buprenorphine-naloxone were assessed in 34 healthy male and female subjects receiving stable addiction management therapy. Subjects continued receiving a stable oral dose of either methadone (up to a maximum dose of 180 mg per day) or buprenorphine-naloxone (up to a maximum dose of 24 mg-6 mg per day) and also received oral faldaprevir (240 mg) once daily (QD) for 8 days following a 480-mg loading dose. Serial blood samples were taken for pharmacokinetic analysis.

Self-reported sedation profile of quetiapine extended-release and quetiapine immediate-release during 6-day initial dose escalation in bipolar depression: a multicenter, randomized, double-blind, phase IV study.

Background: A human-volunteer study reported lower sedation intensity during escalation of the extended-release formulation of quetiapine fumarate (quetiapine XR) than the immediate-release (IR) formulation.

Methods: In a randomized, double-blind, double-dummy, parallel-group, Phase IV study, male and female inpatients aged 18 to 50 years with a Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) diagnosis of bipolar I or II depression were randomized after washout to receive placebo on day 1 and quetiapine XR or IR at escalating doses of 50, 100, 200, 300, and 300 mg once daily on the evenings of days 2 to 6, with hospital discharge on day 7.

Results of a proof-of-concept, dose-finding, double-blind, placebo-controlled study of RX-10100 (Serdaxin®) in subjects with major depressive disorder.

Background: RX-10100 (Serdaxin®), a nonantibiotic small molecule beta-lactam compound, has shown potent antidepressant and anxiolytic activities in preclinical models. RX-10100 does not bind to the serotonin transporter or other receptors associated with monoamine activity. In microdialysis studies with rats, RX-10100 increased the release of dopamine and serotonin metabolites.
