A combination immediate/delayed release delivery system for compounds which have short half-life's, such as the antidiabetic remogliflozin etabonate, is provided which provides a dosage form that has two distinct phases of release, a formulation that promotes immediate release of the compound upon ingestion and another formulation which delays the release of the compound so that a dosing regimen of remogliflozin etabonate, once daily, may be achieved while providing effective control of plasma glucose and minimizing the nighttime exposure of this compound. The delivery system includes, but is not limited to, a combination of enteric coating of an immediate release formulation such that a delay in release is provided. Methods for forming the so-described immediate/delayed release delivery system and using such delivery system for treating diabetes are also provided.
