Abstract
AIM
To evaluate anxiolytic action of GB-115, a low-affinity blocker of central cholecystokinin receptors, used in tablets in a dose of 1 mg for the treatment of patients with anxiety disorders in order to determine effective dose, safety, tolerability and efficacy in clinical settings.
MATERIAL AND METHODS
The study included 31 patients (22 women, 9 men) diagnosed with generalized anxiety disorder (GAD, F41.1 according to ICD-10), aged from 22 to 53 years. The duration of treatment was 21 days. The Hamilton Anxiety Rating scale, Psychopathologic symptoms severity evaluation scale (PSSES), Spilberger State-Anxiety Inventory, Multidimensional Fatigue Inventory (MFI), Clinical Global Impression scale (CGI), computerized battery for evaluation of cognitive functions ('NS-Psychotest') were used.
RESULTS AND CONCLUSION
The effective dose of GB-115 was determined at 6 mg per day. Drug action is characterized by fast onset of anxiolytic effect with stimulating properties and beneficial effect on sleep disturbances and autonomic symptoms. GB-115 treatment was associated with favorable changes in attention parameters, reaction time and overall performance. In contrast to first-line drugs for GAD treatment (SSRIs and SNRIs), GB-115 does not induce initial overactivation, anxiety and sleep disturbances. GB-115 is safe and has a good tolerability.
