Effects of 7.5% CO2 challenge in generalized anxiety disorder
KM Seddon,Kelly Morris,Jayne E Bailey,John Potokar,A. Rich,Sue Wilson,Paolo Bettica,David J. Nutt +7 more
TL;DR: It is shown that 20 min of 7.5% CO2 gas inhalation increases anxiety responses in patients with generalized anxiety disorder, and this is reliable over time.
Journal ArticleDOI
Using sleep to evaluate comparative serotonergic effects of paroxetine and citalopram
TL;DR: REM sleep was significantly suppressed and sleep fragmentation increased by both drugs, suggesting greater effects on 5HT uptake blockade and sleep effects typical of SSRIs were greater with PAR 20mg/day than CIT 20 mg/day.
Journal ArticleDOI

Flumazenil in alcohol withdrawal: a double-blind placebo-controlled study
John Potokar,N.J. Coupland,Paul Glue,Simon Groves,Andrea Malizia,Jayne E Bailey,Sue Wilson,David J. Nutt +7 more
TL;DR: Results from 15 alcohol-dependent subjects in a double-blind placebo-controlled cross-over study showed that flumazenil was neither anxiolytic nor anxiogenic, although withdrawal scores were reduced during the course of the study.
