This mode of action translates into anti-epileptic, analgesic and anxiolytic effects. Gabapentin and pregabalin are considered to have some potential for abuse, physiological dependence, and withdrawal but not on the same magnitude as discussed previously for benzodiazepines. It was designed as a more potent successor to gabapentin. Despite their unique neuronal mechanisms of action, evidence collected from the current and previous studies suggests that benzodiazepines, SSRIs, and pregabalin may share a common regional brain mechanism—namely, the attenuation of insula and/or amygdala activation during emotional processing.

Pregabalin contains a carboxylated chain of hexane called hexanoic acid. Following concerns about abuse, pregabalin has been reclassified as a Class C controlled substance and is now a Schedule 3 drug, but is exempt from safe custody requirements. Pregabalin is similar in structure to other gabapentinoids, such as gabapentin and phenibut. The findings of randomized controlled trials and meta-analyses together indicate that pregabalin is efficacious in both acute treatment and relapse prevention in GAD, with some evidence of an early onset of effect, and broad efficacy in reducing the severity of psychological and physical symptoms of anxiety.

Copyright 2017 Informa PLC. It has also been found effective for generalized anxiety disorder and is (as of 2007) approved for this use in the European Union. Instead, its anxiolytic effects may arise through high-affinity binding to the alpha-2-delta sub-unit of the P/Q type voltage-gated calcium channel in “over-excited” presynaptic neurons, thereby reducing the release of excitatory neurotransmitters such as glutamate. Pregabalin reduces neuronal calcium currents by binding to the alpha-2-delta subunit of calcium channels, and this particular mechanism may be responsible for effects in neuropathic pain, anxiety, and other pain syndromes. Pregabalin is a gabapentin analog and is virtually identical to it in terms of its mechanism of action therapeutic profile (Sills, 2006). Welcome back to our current theme of anxiety disorders.
