Latest Patents
Raymond Chen's latest patents include innovative formulations for alkaline ophthalmic suspensions. These topical ophthalmic medicament delivery systems combine an aqueous ophthalmic gel suspension with a pH equal to or greater than 7.5. The systems maintain an osmotic pressure ranging from 10 to about 400 mOsM. They contain a pharmaceutically effective amount of one or more ophthalmic medicaments, ranging from about 0.05% to about 10% by weight. The formulations utilize a carboxyl-containing polymer, which is prepared by polymerizing one or more carboxyl-containing monoethylenically unsaturated monomers, along with less than about 5% by weight of a cross-linking agent. These systems exhibit a viscosity of approximately 1,000 to about 30,000 centiposes prior to administration. They remain a gel in the eye for an extended period, allowing for the sustained release of medicaments, such as amine-containing antibiotics, either alone or in combination with corticosteroids.
