    摘要: A sustained release pharmaceutical formulation includes a sustained release excipient including a gelling agent, an inert pharmaceutical diluent, an optional cationic crosslinking agent, and a medicament having moderate to poor solubility is disclosed. In certain embodiments, the sustained release excipient is granulated with a solution or suspension of a hydrophobic polymer in an amount effective to slow the hydration of the gelling agent when the formulation is exposed to an environmental fluid. In another embodiment, the tablet is coated with a hydrophobic polymer.
