Nonsedating anxiolytic

Le «digit span», test mnémonique numérique et le test de Trieger nous servaient à mesurer les fonctions cognitives avant et après l’opération.

Les trois médications utilisés n’ont pas démontré de propriétés anxiolytiques différentes, les niveaux d’anxiété allant décroissant dans les trois groupes à partir de l’admission à l’hôpital.

The enantiomers SH-053-2'F-S-CH3 (51) and SH-053-2'F-R-CH3 (52) have been shown to be α2/α3/α5- and α5- subtype selective agonists, respectively.

Both ligands (S)-51 and (R)-52 have been shown to reduce some positive symptoms of schizophrenia; the S-enantiomer 51 was active in the poly(I: C) model of schizophrenia while the R-enantiomer 52 was active in the MAM-model of schizophrenia.

The α2/α3 subtype selective Bz/GABAA receptor positive allosteric modulator HZ-166 (3) has been shown to be a nonsedating anxiolytic with anticonvulsant and antihyperalgesic activity.

However, instability in vitro and in vivo has hindered its advancement into clinical trials.

Après randomisation à double-insu, elles prenaient par la bouche soit 10 mg de diazépam (n = 31), soit 80 mg de propranolol (n = 31), soit un placebo (n = 30) et ce, de 60 à 90 minutes avant l’intervention.

Nous mesurions le niveau d’anxiété à l’admission, juste avant d’entrer en salle d’opération et deux heures après l’intervention en utilisant le «State-Trait Anxiety Inventory (STAI)».

However, pharmacokinetic studies indicated that esters as a functional group may not be suitable for extensive preclinical studies.Tests of cognitive function after anaesthesia showed the fastest return to baseline status in patients receiving propranolol, possibly because beta adrenergic blockade blunted the autonomic signs of light anaesthesia and less anaesthetic was administered.None of the study premedications was demonstrated to have an anxiolytic advantage, but propranolol did offer a faster return of cognitive function in the postoperative period.This methyl amide 65 was shown to activate α5 subtypes in vivo in rats at low concentrations, providing a valuable tool to study the α5 GABAA receptor subtype.



The azapirone class of drugs. Buspirone was the first non-BZ nonsedating anxiolytic approved for the treatment of GAD. 93 Despite its clinical efficacy.… continue reading »
