Abstract

Pharmaceutical forms have a solid, medicament-containing core completely covered by a film-forming coating material containing wax-free shellac which has been rendered water-soluble by dissolution in aqueous ammonia. Suitable forms are tablets, pills, pellets and troches, to which the coating is applied as a coating composition of shellac in aqueous ammonia, preferably with added organic solvents and a plasticizer for the shellac. Application is carried out in a coating pan by spraying the composition on to the forms followed by warm air drying. The composition is prepared by dissolving the wax-free shellac in just enough aqueous ammonia to form a solution; an organic solvent may then be added to improve the drying rate of the solution, e.g. alcohol and chloroform; and a plasticizer such as solid polyethylene glycol, polyvinylpyrrolidone, di-butyl- or di-methyl-phthalate, di-iso butyl adipate, castor oil, mineral oil, propylene glycol, stearyl alcohol, cetyl alcohol, and higher fatty acid glycerides. The coating compositions may also include opacifying agents such as barium sulphate, calcium carbonate or titanium dioxide, and dyes and lakes. Examples are given for coating tablets containing trifluoperazine, dextro-amphetamine, or chlopromazine.
