Dronabinol/palmidrol (developmental code names SCI-110, THX-OSA01, THX-RS01, THX-110, and THX-TS01), also known as Δ9-tetrahydrocannabinol/palmitoylethanolamide (THC/PEA), is a combination of dronabinol (Δ9-THC), a cannabinoid CB1 and CB2 receptor agonist, and palmidrol (palmitoylethanolamide; PEA), an endocannabinoid-like fatty acid amide with various cannabidiol (CBD)-like actions, which is under development for the treatment of agitation, Alzheimer's disease, Tourette's syndrome, and sleep apnea syndrome.[1][2][3][4][5] It was also under development for treatment of back pain, but development for this indication was discontinued.[1] The drug is taken orally.[1] It is thought that palmidrol may enhance the effectiveness and tolerability compared to dronabinol alone.[4] The drug was originated by Therapix Biosciences and is being developed by SciSparc.[1][2] As of September 2025, the drug is in phase 2 clinical trials for all active indications.[1][2]

Furthermore, different cannabis-based approaches are being investigated including dronabinol (tetrahydrocannabiniol (THC)) in combination with palmitoylethanolamide (PEA) as well as pure cannabidiol (CBD) – also known as Epidiolex® or Epidyolex® - and an oral oily cannabis extract with a ratio of THC: CBD at 10:15. It is believed that combinations of THC with either PEA or CBD may cause an "entourage effect" resulting in increased efficacy and reduced adverse effects compared to pure THC [28].
