Abstract
Substantially spherical granules of phenacetin are prepared by spraying liquid phenacetin which has been melted without decomposition by means of rapid passage through a melting device in which superheating is minimized. The resultant melt-sprayed granules are superior to crystalline phenacetin in the formulation of pharmaceutical tablets.
