Cannabidiol (CBD) has proven to be an effective adjunct drug, but oral preparations have low bioavailability, slow onset and systemic adverse effects. Nanostructured lipid carriers (NLCs) are an innovative therapeutic technology that can deliver CBD directly to the brain via the nose, enhance brain targeting, achieve faster onset, and minimize systemic exposure, which could be a valuable solution to current deficiencies in treatment.Intranasal NLC-CBD has preclinical evidence of increasing brain CBD levels, facilitating anticonvulsant action, and protecting against seizures in established animal models, like pentylenetetrazol-induced convulsions.
