Pregabalin is an anticonvulsant originally developed as a successor for gabapentin to which it is structurally closely related. It is considered the drug of choice for central and peripheral neuropathic disorders and for the treatment of fibromyalgia and certain forms of epilepsy.
92-99% of pregabalin is excreted unchanged in urine. Its elimination half-time is approximately 6 to 7 hours. Although pregabalin is officially considered to have a low potential for abuse, a growing number of publications are reporting abuse, especially in patients with a previous history of addiction. In addition, patients treated with pregabalin appear to develop a tolerance that may easily slip into addiction, especially with regular use. The same publications report on serious withdrawal symptoms.
The known side effects include a feeling of euphoria, relaxation, significantly increased self-confidence, loss of inhibitions, as well as concentration issues, dizziness and visual distortions. In combination with alcohol, benzodiazepines or opioids, these effects may be multiplied.
