Summary for Patent: 4,758,598
Title: Solid shaped articles
Abstract:Solid shaped articles, particularly pharmaceutical dosage forms, are prepared by freezing in a mould a composition comprising a predetermined amount of chemical (e.g. pharmaceutical) and a solution of carrier material and then subliming solvent from the frozen composition. The side wall or walls of the mould make an angle with the vertical of at least 5.degree. at the surface of the composition. This enables shaped articles of constant thickness to be produced with minimum sublimation times.
