Leslie J. Crofford studied the efficacy of pregabalin for treating symptoms of generalized anxiety disorder has been demonstrated in several clinical trials (42, 43). As such, it is possible that improvements in pain scores reported by patients could be a by-product of a positive anxiolytic effect. However, in the present trial, there were no significant changes in HADS anxiety scores at end point from those at baseline. This suggests that patient-reported changes in pain scores are not a product of improvements in symptoms of anxiety; rather, improvements in pain scores are independent of anxiety symptom status. ebiochem.com
Usually the patient will on a low dose of pregabalin and increase it gradually, depending on the patient’s evaluation. Its therapeutic effect appears after 1 week of use and is similar in effectiveness to lorazepam, alprazolam and venlafaxine but pregabalin has demonstrated superiority by producing more consistent therapeutic effects for psychic and somatic anxiety symptoms. Long-term trials have shown continued effectiveness without the development of tolerance and additionally unlike benzodiazepines it does not disrupt sleep architecture and produces less severe cognitive and psychomotor impairment; it also has a low potential for abuse and dependence and may be preferred over the benzodiazepines for these reasons.
