Olfactory delivery of therapeutic compounds to the central nervous system
The present invention provides materials and methods for treating symptoms of neurological conditions. More specifically, the subject invention provides compositions and methods of their use for treating one or more symptoms and/or comorbidities of a neurological condition such as an infection, a neurodevelopmental disease, and/or a neurodegenerative disease. In preferred embodiments, the composition is administered to the subject via nasal administration.
1. A method for treating neurological inflammation, the method comprising, administering, via the nasal cavity, a composition comprising a sophorolipid, a mannosylerythritol lipid, and an antioxidant, to a subject in need of such treatment, wherein the sophorolipid and the mannosylerythritol lipid are in the form of a liposome and the antioxidant is encased in the liposome, and
wherein the neurological inflammation is caused by head trauma, a brain tumor, an allergic reaction, a neurodegenerative disease, or an infection.
2. The method of claim 1 , wherein administration is carried out using a syringe, dropper, pump action nasal spray, nebulizer, atomizer, and/or an exhalation powered nasal device.
3. The method of claim 1 , wherein the composition is administered to the subject 4 or 5 times daily.
4. The method of claim 1 , wherein the composition further comprises glycerol and/or glycerin as a smoothing agent.
5. The method of claim 1 , wherein the composition further comprises a salt as an emulsifier.
6. The method of claim 1 , wherein the composition is formulated as a liquid or a powder.
7. The method of claim 1 , wherein the composition is administered via the nasal cavity at a total volume of 0.01 ml to 5 ml per dose.
8. The method of claim 1 , wherein the neurological inflammation is caused by a neurodegenerative disease.
9. The method of claim 1 , wherein the antioxidant is N-acetyl-L-cysteine.
10. The method of claim 1 , wherein the composition further comprises at least one plant extract or essential oil selected from the group consisting of eucalyptus oil, clove oil, and tea tree oil.
