The Off-Label Benefits of Riluzole in Anxiety, OCD, Skin Excoriation Disorder, and Trichotillomania
Managing mental health disorders such as anxiety and obsessive-compulsive disorder (OCD) can be challenging. At Philadelphia Integrative Psychiatry, Dr. Danish and his team are dedicated to providing personalized care that addresses these challenges. One promising treatment we frequently explore is riluzole, a medication traditionally used for amyotrophic lateral sclerosis (ALS), which has shown potential benefits in mental health care.
Riluzole’s significance in our practice stems from its unique action on the glutamatergic system, which is implicated in several psychiatric conditions. This medication offers a novel approach to managing symptoms of anxiety and OCD, especially when traditional treatments have not been fully effective.
Neuroprotective Effects of Riluzole
In the article "The pharmacology and mechanism of action of riluzole", riluzole is highlighted as a neuroprotective drug that primarily functions by blocking glutamatergic neurotransmission in the central nervous system (CNS). It achieves this by inhibiting the release of glutamic acid from neurons, which is thought to occur through the inactivation of voltage-dependent sodium channels and activation of a G-protein-dependent signal transduction process. Riluzole also blocks postsynaptic effects of glutamic acid by noncompetitively inhibiting NMDA receptors. These actions contribute to its neuroprotective, anticonvulsant, and sedative properties observed in vivo. In rodent models, riluzole has demonstrated the ability to completely suppress ischemia-induced surges in glutamic acid release, and in vitro studies show it protects neurons from anoxic damage and toxic effects related to amyotrophic lateral sclerosis (ALS), its FDA approved use.
How Riluzole Improves Anxiety and OCD According to Recent Studies
Anxiety Disorders
Riluzole has been investigated for its effects on generalized anxiety disorder (GAD). In an open-label trial, patients showed significant reductions in anxiety symptoms after an eight-week treatment period. This suggests that riluzole may help alleviate anxiety symptoms, offering hope for those who have not responded to standard treatments.
Obsessive-Compulsive Disorder
For OCD, riluzole has been studied as an augmentation therapy alongside selective serotonin reuptake inhibitors (SSRIs). Some trials reported improvements in OCD symptoms, particularly in treatment-resistant cases. However, results have been mixed, with some studies showing significant benefits and others indicating no substantial difference compared to placebo.
Skin Excoriation and Trichotillomania (Hair Pulling)
For skin excoriation and trichotillomania, studies are ongoing. Anecdotal experience by Dr. Danish and colleagues has shown considerable benefit when riluzole is added to other agents that can help address these and related disorders.
Safety and Tolerability
Riluzole is generally well-tolerated with few serious adverse effects reported in psychiatric applications; however, this is unique to each patient so it’s imperative that you discuss the pros and cons of this medication with your healthcare provider.
Potential side effects include nausea, dizziness, drowsiness, fatigue, abdominal pain, constipation, headache, dry mouth, increased appetite, decreased appetite, diarrhea, and increased liver-function tests. These side effects are infrequent and typically mild.
Dosing
At Philadelphia Integrative Psychiatry, we typically start riluzole at a dose of 50 mg taken twice daily, in the morning and at night. This allows us to monitor the patient's response and tolerance to the medication. If needed, the dose can be increased to 100 mg twice daily.
Riluzole has a half-life of approximately 12 hours, which supports this twice-daily dosing regimen. This pharmacokinetic property helps maintain stable drug levels in the bloodstream, optimizing therapeutic effects while minimizing potential side effects.
Potential Interactions
Riluzole interacts with 66 drugs, including 7 major interactions that should be avoided due to significant risks. Notably, drugs like abametapir and givosiran can increase riluzole levels, leading to adverse effects. Riluzole is metabolized by the CYP1A2 enzyme, so inhibitors of this enzyme (e.g., ciprofloxacin, fluvoxamine) can raise riluzole's concentration, while inducers may reduce its efficacy.
Additionally, alcohol can enhance riluzole's hepatotoxic potential, so alcohol consumption should be limited while taking this medication.
