Abstract:
1. A silicone hydrogel comprising at least one pharmaceutical or nutraceutical component wherein said silicone hydrogel is formed from a reaction mixture comprising about 37 to about 75 wt % of a mixture of slow-reacting hydrophilic monomers, each having a slow-reacting hydrophilic monomer kinetic half life; said mixture of slow reacting hydrophilic monomers comprising at least one slow-reacting ionic monomer; at least one silicone-containing component having a silicone-containing component kinetic half life, which may be optionally substituted with at least one hydroxyl containing group; and at least one hydroxyl-containing component selected from said silicone-containing components substituted with at least one hydroxyl containing group, at least one hydroxyalkyl monomer, and mixtures thereof, wherein ratio of each of said slow-reacting hydrophilic component half lives to said silicone-containing component half life is at least 2.
