Pregabalin and gabapentin are sometimes used off-label to manage anxiety disorders, particularly generalized anxiety disorder (GAD). Both drugs work by altering the activity of neurotransmitters to reduce neural excitability and lower anxiety symptoms. Gabapentin has been shown to be effective in reducing symptoms of anxiety in social anxiety disorder and mixed results in panic disorder (significant improvement in more severely ill). It is also likely effective for other anxiety disorders such as GAD but is not well studied. The gabapentinoids, gabapentin, and pregabalin, target the α<sub>2</sub>δ subunits of voltage-gated calcium channels. Initially licensed for pain and seizures, they have become widely prescribed drugs. Many of these uses are off-label for psychiatric indications, and there is increasing concern abou An early onset of effect in reducing anxiety symptoms is considered beneficial in treating patients with anxiety disorders, but the findings of randomized controlled trials tend to indicate that a few weeks pass before antidepressants are superior to placebo. 40 Pregabalin has been found superior to placebo in reducing anxiety in patients prior In this review, the author examines the evidence for psychopharmacologic treatments among adults for generalized anxiety disorder, panic disorder, and social anxiety disorder derived from clinical trials. For each disorder, major categories of drugs are reviewed, and then the evidence-based medications in each category are discussed. Pregabalin (Lyrica) and gabapentin (Neurontin) are medications that treat certain types of seizures and nerve pain. Pregabalin has more FDA approved uses. Both are frequently used off-label for a wide range of health conditions. When comparing pregabalin versus gabapentin, they work in similar ways but pregabalin is absorbed more quickly and fully.

[Google Scholar] Stahl SM. Anticonvulsants as anxiolytics: Part 2. Pregabalin and gabapentin as alpha(2)delta ligands at voltage-gated calcium channels. Anxiety disorders are the most common type of psychiatric illness, with a 12-month prevalence approaching 1 in 5 adults (18.1%). 1 Generalized anxiety disorder (GAD) is the most frequent anxiety disorder, affecting about 5% of adults in the primary care setting. 2 Often suffering since childhood or adolescence, 2 individuals with GAD experience a constant state of worry and anxiety on most The study also stated that Gabapentin could be a reasonable alternative to Pregabalin for the treatment of anxiety disorders, but the available evidence does not fully support this theory [7]. Pregabalin And Gabapentin – Warnings And Precautions Anxiety: In a small clinical trial, gabapentin was shown to be more effective for anxiety, insomnia, and fatigue symptoms in adults with low-back pain. However, the trial found that pregabalin was more effective for pain reduction. Lyrica (pregabalin) and Neurontin (gabapentin) are both classified as “gabapentinoids” (i.e. α2δ ligands). As gabapentinoids, Lyrica (pregabalin) and Neurontin (gabapentin) are chemical analogues of the inhibitory neurotransmitter GABA (gamma-aminobutyric acid) that interact with α2δ subunit-containing voltage-dependent calcium channels. This review will focus on the comparative properties of gabapentin and pregabalin, specifically the available evidence on their use in the treatment of primary anxiety disorders — GAD, social anxiety disorder, panic disorder, and obsessive-compulsive disorder. The gabapentinoids, gabapentin, and pregabalin, target the α2δ subunits of voltage-gated calcium channels. Initially licensed for pain and seizures, they have become widely prescribed drugs. %PDF-1.4 %€„ˆŒ ”˜œ ¤¨¬°´¸¼ÀÄÈÌÐÔØÜàäèìðôøü 22 0 obj /T 139448 /L 140038 /Linearized 1 /E 56541 /O 24 /H [ 1092 303 ] /N 5 >> endobj Pregabalin is a prescription medication used to treat nerve pain, epilepsy, and generalized anxiety disorder. It works by calming overactive nerve signals in the brain, helping to reduce pain and seizures. Doctors commonly prescribe it for conditions like fibromyalgia, diabetic nerve pain, and pain related to spinal cord injuries. The gabapentinoids, gabapentin, and pregabalin, target the α2δ subunits of voltage-gated calcium channels. Initially licensed for pain and seizures, they have become widely prescribed drugs. Many of these uses are off-label for psychiatric Prescription rates for gabapentinoids are rising in England. Pregabalin is currently recommended by NICE for the treatment of anxiety. Gabapentinoids have some overlap with the action of benzodiazepines, and have similar issues with tolerance, dependence, addiction and withdrawal. They were schedule Choosing gabapentin and pregabalin: These drugs are widely used off-label as an alternative to benzodiazepines for anxiety disorders. The speed of their onset of action has not been clearly established, but many clinicians have the impression that it is often within a few days, much shorter than that for antidepressants. Pregabalin and gabapentin are gabapentinoids used to manage anxiety disorders such as GAD, SAD, and PTSD. Pregabalin (Lyrica) exhibits higher affinity for alpha2-delta ligands than gabapentin (Neurontin), resulting in more potent activity.
