An electrostatic 'image' having a given size and charge density is exposed to ionized drug powder to attract a known amount of drug to the image. The resultant drug 'image', is then transferred to a an open ended capsule, a partially formed tablet or edible wafer or belt. The capsule is then sealed, i.e. by capping, or the tablet finished.
