The mechanisms of action vary among different types of anxiolytic medications:
Benzodiazepines enhance the effect of the neurotransmitter GABA, leading to a calming effect. SSRIs and SNRIs increase the levels of serotonin and norepinephrine in the brain, which can improve mood and reduce anxiety. Buspirone acts on serotonin receptors, providing relief from anxiety without the sedative effects commonly associated with benzodiazepines.
