The dosage forms include a mixture of coarse and fine particles of modafinil. The process for preparing modafinil oral dosage forms includes forming a dosage form that includes about 7%–25% by weight of modafinil particles having diameters greater than 220 μm and about 75%–93% by weight of modafinil particles having diameters less than 220 μm.Field of SearchParticulate form (e.g., powders, granules, beads, microcapsules, and pellets)Sustained or differential release With claimed designated perfecting feature in contents (e.g., excipient, lubricant, etc.) With claimed perfecting feature in contents (e.g., excipient, lubricant, etc.) Capsules (e.g., of gelatin, of chocolate, etc.) Tablets, lozenges, or pills | |
