The Influence of Ritanserin, a Serotonin Antagonist, in Anxiety Disorders: A Double-blind Placebo-controlled Study versus Lorazepam
Abstract
A double-blind study was performed in 83 patients with generalized anxiety disorder comparing daily doses of 5 and 10 mg ritanserin (a selective antagonist of serotonine S 2 receptors) versus placebo and 4 mg lorazepam as reference drug. Patients treated with 10 mg ritanserin or 4 mg lorazepam improved significantly better (p<0.05) after two weeks than those treated with placebo. On the other hand a daily dose of 5 mg ritanserin appeared to be not superior to placebo. Patients treated with 4 mg lorazepam complained significantly more about sedation and dizziness than patients treated with 10 mg ritanserin (p<0.05). Zusammenfassung Eine Doppelblindstudie wurde an 83 Patienten mit Angstund Spannungszuständen durchgeführt, wobei Tagesgaben von 5 und 10 mg Ritanserin (eines selektiven Serotonin-S 2 - Rezeptorentagonisten) gegen Plazebo und 4 mg Lorazepam als Bezugspräparat verglichen wurden. Die mit 10 mg Ritanserin oder 4 mg Lorazepam behandelten Patienten zeigten eine signifikant größere Verbesserung (p<0.05) nach 2 Wochen als die mit Plazebo behandelten Patienten. Andererseits erschien eine Tagesdosis von 5 mg Ritanserin der Plazebogabe nicht überlegen. Patienten, die mit 4 mg Lorazepam behandelt worden waren, klagten signifikant häufiger über Sedierung und Schwindelgefühl als diejenigen Patienten, welche mit 10 mg Ritanserin behandelt wurden (p < 0.05).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
