Pregabalin (Molecule of the Month for May 2017)

Lyrica



Pregabalin is a medication used to treat epilepsy, neuropathic pain, fibromyalgia, and generalized anxiety disorder.] Its use for epilepsy is as an add-on therapy for partial seizures with or without secondary generalization in adults. Some off-label uses of pregabalin include restless leg syndrome, prevention of migraines,[14] social anxiety disorder, and alcohol withdrawal.] When used before surgery it does not appear to affect pain after surgery but may decrease the use of opioids.

The European Federation of Neurological Societies recommends pregabalin as a first line agent for the treatment of pain associated with diabetic neuropathy, post-herpetic neuralgia, and central neuropathic pain. A minority obtain substantial benefit, and a larger number obtain moderate benefit.[28] Other first line agents, including gabapentin and tricyclic antidepressants, are given equal weight as first line agents, and unlike pregabalin, are available as less expensive generics.

The World Federation of Biological Psychiatry recommends pregabalin as one of several first line agents for the treatment of generalized anxiety disorder. The effects of pregabalin appear 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 psychosomatic anxiety symptoms. Long-term trials have shown continued effectiveness without the development of tolerance, and, in addition, unlike benzodiazepines, it has a beneficial effect on sleep and sleep architecture, characterized by the enhancement of slow-wave sleep. It produces less severe cognitive and psychomotor impairment compared to those drugs; it also has a low potential for abuse and dependence and may be preferred over the benzodiazepines for these reasons.
