Patent ID: 8190271

Claim:
A method for delivering dexamethasone base (DXMb) via an implantable electrode comprising: coupling said DXMb and dexamethasone (DEX) salt to said implantable electrode by: coating said implantable electrode with a layer of DXMb, overcoating said layer of DXMb with a hydrophilic lubricant, and applying a solution containing said DEX salt to said lubricant by soaking said implantable electrode in a solution containing DEX salt prior to use said solution being absorbed by said lubricant; and inserting said implantable electrode into biological tissue, said DXMb and said DEX salt eluting into said biological tissue, wherein said DEX salt is configured to rapidly elute into said biological tissue and said DXMb is configured to more slowly elute into said biological tissue at a lower concentration than said DEX salt.
