Abstract
Objective
Fasedienol (PH94B) is a pherine compound formulated as a nasal spray that is hypothesized to regulate olfactory-amygdala circuits of fear and anxiety. Fasedienol's effect on the local electrogram of nasal chemosensory neurons (EGNR) and autonomic nervous system (ANS) responses versus steroidal hormones and controls in healthy adults is reported.
Methods
Eight males and 8 females randomly received aerosolized control (propylene glycol) and study drugs (fasedienol, 17β-estradiol, progesterone, cortisol, and testosterone, 0.4 μg each in propylene glycol) onto the nasal septum mucosal lining at 30-min intervals over 2 sessions. EGNR was continuously monitored; autonomic parameters were recorded before and after administration.
Results
Fasedienol significantly increased EGNR amplitude (males: 5.0 vs. 0.6 mV, p < 0.001; females:5.7 vs. 0.6 mV, p < 0.001), and rapidly reduced respiratory rate (p < 0.05), heart rate (p < 0.01), and electrodermal activity (p < 0.05) versus control. EGNR and ANS responses after steroidal hormone administration were similar to control. 81% reported feeling less tense/more relaxed after receiving fasedienol, but not after receiving either control or steroidal hormones.
Conclusions
Intranasal fasedienol, but not control or steroidal hormones, activated EGNR and rapidly reduced ANS responses, consistent with sympatholytic effects. Combined with subjective reports, results suggest fasedienol may provide acute relief in anxiety conditions.
期刊介绍:
Human Psychopharmacology: Clinical and Experimental provides a forum for the evaluation of clinical and experimental research on both new and established psychotropic medicines. Experimental studies of other centrally active drugs, including herbal products, in clinical, social and psychological contexts, as well as clinical/scientific papers on drugs of abuse and drug dependency will also be considered. While the primary purpose of the Journal is to publish the results of clinical research, the results of animal studies relevant to human psychopharmacology are welcome. The following topics are of special interest to the editors and readers of the Journal:
-All aspects of clinical psychopharmacology-
Efficacy and safety studies of novel and standard psychotropic drugs-
Studies of the adverse effects of psychotropic drugs-
Effects of psychotropic drugs on normal physiological processes-
Geriatric and paediatric psychopharmacology-
Ethical and psychosocial aspects of drug use and misuse-
Psychopharmacological aspects of sleep and chronobiology-
Neuroimaging and psychoactive drugs-
Phytopharmacology and psychoactive substances-
Drug treatment of neurological disorders-
Mechanisms of action of psychotropic drugs-
Ethnopsychopharmacology-
Pharmacogenetic aspects of mental illness and drug response-
Psychometrics: psychopharmacological methods and experimental design
