Described herein are PPARα agonists, including, but not limited to, endocannabinoids that can be used for treatment of a neuropsychiatric disorder and/or symptom thereof. Also described herein are pharmaceutical formulations containing an effective amount of a PPARα agonists, including but not limited to endocannabinoids, where the effective amount is effective for treating a neuropsychiatric disorder and/or symptom thereof. Also described herein are methods of treating a neuropsychiatric disorder and/or a symptom thereof in a subject in need thereof.
1. A method of treating a post-traumatic stress disorder (PTSD) in a subject in need thereof, the method comprising:
administering an effective amount of an endocannabinoid PPARα agonist to the subject in need thereof, wherein the subject in need thereof has not responded to treatment with one or more selective-serotonin reuptake inhibitors.
2. The method of claim 1 , wherein the endocannabinoid is arachidonoylethanolamine (AEA), oleoyldopamine (OEA), palmitoylethanolamide (PEA), stearoylethanolamide (SEA) or any combination thereof.
3. The method of claim 2 , wherein the endocannabinoid is PEA.
4. The method of claim 3 , wherein the effective amount of PEA can range from about 5 mg/kg to about 20 mg/kg.
5. The method of claim 1 , further comprising the step of detecting a biomarker for PTSD in a sample from the subject in need thereof.
6. The method of claim 5 , wherein the biomarker for PTSD is the amount of endogenous neurosteroids, endocannabinoids and their congeners, or the ratio thereof, in a bodily fluid sample of the subject in need thereof.
7. The method of claim 6 , wherein the neurosteroid comprises allopregnanolone, allopregnanolone sulfate, pregnanolone sulfate, or a combination thereof.
8. The method of claim 6 , wherein the endocannabinoids and their congeners comprises N-Palmitoylethanolamine (PEA), oleoyldopamine (OEA), stearoylethanolamide (SEA), N-arachidonoylethanolamine (AEA), or a combination thereof.
