Disclosed are osmotic dosage forms and methods that provide for fast release of drugs together with controlled release of drugs. In an aspect, disclosed are osmotic dosage forms including: a semi-permeable membrane; a lubricating subcoat located within the semi-permeable membrane; an orifice in the semi-permeable membrane located at an end of the semi-permeable membrane; a drug layer located adjacent to the orifice and within the lubricating subcoat; a push layer located within the lubricating subcoat and on a side of the drug layer opposite from the orifice; wherein an area of the orifice is greater than or equal to about 1,600 mil2; and wherein the drug layer comprises from about 20 wt % to about 90 wt % microcrystalline cellulose, and less than or equal to about 10 wt % of a drug, based on the total weight of the drug layer. Also disclosed are methods of making osmotic dosage forms.
