Gabapentin in the acute treatment of refractory bipolar disorder. Lori L. Altshuler, Paul E. Keck, Susan L. McElroy, Gabapentin appears to have acute anti-manic and anti-depressant properties as an adjunctive agent for refractory bipolar illness. Prospective double-blind studies are needed to further delineate its acute efficacy when used as monotherapy and its prophylactic efficacy as monotherapy or in conjuction Introduction Gabapentin has been extensively prescribed off-label for psychiatric indications, with little established evidence of efficacy. Gabapentin and pregabalin, a very similar drug with the same mechanism of action, bind to a subunit of voltage-dependent calcium channels which are implicated in the aetiopathogenesis of bipolar disorder, anxiety and insomnia. This systematic review and Gabapentin has an average rating of 8.5 out of 10 from a total of 138 reviews for the off-label treatment of Bipolar Disorder. 81% of reviewers reported a positive experience, while 9% reported a negative experience. Prescribers wish that gabapentin had utility in bipolar disorder because gabapentin isn’t a P450 substrate, is renally excreted, and is generic and thus relatively affordable. Unfortunately, gabapentin does not demonstrate efficacy in randomized trials for bipolar disorder and current treatment guidelines do not emphasize its use. Gabapentin may be a useful drug for the add-on treatment of bipolar patients with poor response to other mood stabilizers. Gabapentin may improve depressive residual symptoms such as irritability, social withdrawal or anxiety. These results should be confirmed in randomized clinical trials. Other medications, like topiramate (Topamax) or gabapentin (Neurontin), may be prescribed in some cases when other treatments haven’t worked. Bipolar 1 Disorder and Bipolar 2 Disorder: What Abstract. Despite its prevalence and disease burden, several chasms still exist with regard to the pharmacotherapy of bipolar disorder (BD). Polypharmacy is commonly encountered as a significant proportion of patients remain symptomatic, and the management of the depressive phase of the illness is a particular challenge. Objectives: To assess efficacy and safety of gabapentin in the treatment of bipolar disorder. Methods: This was a double-blind, placebo-controlled trial of adjunctive gabapentin (dosed flexibly between 900 and 3600 mg/day). For bipolar disorder, four double-blind RCTs investigating gabapentin, and no double-blind RCTs investigating pregabalin, were identified. A quantitative synthesis could not be performed due to heterogeneity in the study population, design and outcome measures. In another study of 16 bipolar I and II patients receiving adjunctive gabapentin (mean dose of 1,310 mg/d), 8 showed improved depression, anxiety, and irritability symptoms at 12-week follow-up. 34 Sokolski et al 35 noted in an open-label add-on trial (n = 10) that gabapentin was effective, with improvement in depressive symptoms, mania ratings Twenty-two RDC bipolar 1 and II patients were assessed by means of the SADS and entered if they gave their consent to participate. All them had suffered from frequent relapses, subsyndromal features (mostly depressive) and incomplete response to other drugs. They all received open-label increasing doses of gabapentin until clinical response.

Apart form its primary indication for Despite of the lack of evidence, reviews of gabapentin prescribing patterns in the United States show that this medication is still being used with alarming frequency for bipolar disorder. There are now five medications with specific, FDA approval for acute bipolar depression. Method: Twenty-five patients fulfilling DSM-IV diagnostic criteria for bipolar I disorder or schizoaffective disorder underwent a 16-week, open-trial treatment with gabapentin. Symptom severity was measured using the Clinical Global Impressions scale (CGI) and the Brief Psychiatric Rating Scale (BPRS). Gaba-pentin is licensed for use in the USA for the treatment of focal seizures and post-herpetic neuralgia [1] and in the UK for focal seizures and peripheral neuropathic pain [2]. Pregabalin Lithium and gabapentin. Gabapentin is currently being studied as a treatment for bipolar disorder, and there have been favorable reports regarding its potential as a mood stabilizer (82, 83). The advantages of gabapentin include the lack of interactions with other drugs in the cytochrome P450 system and the lack of protein binding . Since there Evidence does not support the use of gabapentin for bipolar disorder, major depressive disorder (MDD), posttraumatic stress disorder (PTSD), obsessive compulsive disorder (OCD), stimulant use disorder, or opioid withdrawal. Background: with increasing awareness of lithium's limitations, several new anticonvulsants had been tested for their mood stabilisation during recent years. Among the innovative third generation mood stabilizing anticonvulsants, gabapentin (GBP) seems to have a broad spectrum of efficacy, although no certain data are available as to its efficacy and use in clinical practice. A recent survey using the US-based TriNetX electronic health records network showed that gabapentin had been prescribed at least once in 13.6% of patients with bipolar disorder (BD), 11.5% with
