    摘要: Embodiments of a pharmaceutical formulation comprising an enteric material are disclosed. The embodiments release at least a portion of an active ingredient upon contacting gastric fluid. The remaining portion of the formulation releases active ingredient upon contacting intestinal fluid. Certain embodiments of the pharmaceutical composition comprise at least one active ingredient in a core and a leaky enteric coating, such as an enteric coating comprising a gastric fluid channeling agent. Other embodiments of the pharmaceutical composition comprise at least one active ingredient substantially homogeneously admixed with at least one enteric material, such as an enteric material comprising a gastric fluid channeling agent. Disclosed embodiments of the pharmaceutical composition may comprise a single active ingredient, or may comprise plural active ingredients. Generally, but not necessarily, the active ingredient has a window of absorption. The present disclosure also describes a method for treating a subject having a condition treatable by an active ingredient. The method comprises providing one or more embodiments of the pharmaceutical composition disclosed herein comprising an active ingredient suitable for treating the condition. The pharmaceutical composition is administered to the subject. A method for making embodiments of the disclosed composition also is described. The method comprises providing a core comprising an active ingredient. An enteric material is applied to at least a portion of the core, and generally on or about a substantial portion of the core, to form a coat. The composition is then made leaky.

    摘要: A pharmaceutical MR (modified release) multiparticulate dosage form such as a capsule (once-a-day MR Capsule) of Methylphenidate indicated for the treatment of children with attention deficit hyperactivity disorder (ADHD), capable of delivering a portion of the dose for rapid onset of action and the remainder of the dose in a controlled manner for about 12 hours, is composed of a multitude of multicoated particles made of two populations of drug layered beads, IR (immediate release) and ER (extended release) Beads. The IR beads preferably are made by layering an aqueous solution comprising a drug and a binder on to non-pareil sugar spheres and then applying a seal coat to the drug coated cores. The ER Beads are made by applying an extended release coating of a water insoluble dissolution rate controlling polymer such as ethylcellulose to IR Beads. The MR Capsules are manufactured by filling IR and ER Beads in a proper ratio; the dose and the ratio required for an efficacious, cost effective and patient compliant treatment of children with ADHD were determined from extensive clinical investigations and in vitro/in vivo correlations performed as per FDA Guidelines, Guidance for Industry: Extended Release Oral Dosage Forms.
