<p>A method of coating a pharmaceutical substrate, especially a tablet core, wherein a pharmaceutically acceptable powder coating material comprising active material is electrostatically applied to a surface of the substrate, wherein the coated substrate constitutes a dosage unit; and a powder coating material suitable for use in the electrostatic powder coating of a pharmaceutical substrate, in which the material is pharmaceutically acceptable, is treatable to form a film coating and includes composite particles, the composite particles comprising two or more components having different physical and/or chemical properties, the material comprising active material. The pharmaceutical substrate may contain the same active material as the powder coating material or may contain a different active material from the powder material or may contain no active material.</p> |
