Abstract
A method of coating tablets with a high molecular weight polymer wherein the high molecular weight polymer is suspended in a non-solvent, non-aqueous liquid carrier. The liquid carrier may include a low-viscosity binder. Preferably, the binder is included in concentrations of around 1-10% by weight in solution in the carrier. The high molecular weight polymer may be micronized prior to its suspension in the liquid carrier. Once suspended, the liquid is introduced into a spray coating machine such as a partially or fully perforated pan system wherein the tablets are coated as desired.
