ABSTRACT:
The present invention provides a method and apparatus for dry coating solid dosage forms. The method includes the steps of placing solid dosage forms in a rotatable, electrically grounded housing, and spraying a film forming polymer powder composition into the housing during rotation thereof to form a polymer coating on the solid dosage forms, the polymer powder composition being sprayed using an electrostatic spray gun, and curing the coated solid dosage forms.
