Abstract

The invention is related to a method of administering a controlled release central nervous system drug by means of sol-gel nanostructured titania reservoir comprising silica, titania and silica-titania, and comprising partially hydrodyzed nano-materials. This reservoir may be in the form of a xerogel.

Claims

exact text as granted — not AI-modified
1 . In a method of administering a controlled release central nervous system (CNS) drug to a patient in need thereof, the improvement wherein the drug is carried by a sol-gel nanostructured titania reservoir comprising silica, titania and silica-titania, and comprising partially hydrolyzed nano-materials. 
     
     
         2 . The method of  claim 1 , wherein the reservoir is the form of a xerogel. 
     
     
         3 . The method of  claim 2 , wherein the reservoir comprises a neurological drug occluded within its interior. 
     
     
         4 . The method of  claim 2  wherein the reservoir is biocompatible with a surrounding brain tissue.
