Abstract

A fluid composition suitable for coating tablets consists essentially of about 10 to 25 parts by weight of a "water-soluble" wax as hereinafter defined and about 2 to 10 parts by weight of a polyvinylpyrrolidone-vinyl acetate copolymer per 100 ml. of the composition and a non-aqueous solvent for said wax and said copolymer. The waxes are polyethylene glycols of melting point of at least 50 DEG C., glyceryl monostearate and diglycol stearate, or mixtures thereof. The copolymers contain 30-70, and preferably 60% of vinylpyrrolidone and 70 to 30% and preferably 40% of vinyl acetate. Optional ingredients are (a) dyes, lakes and pigments (b) water-insoluble waxes such as beeswax, lanolin, stearic acid, cocoa butter and cetyl alcohol (c) plasticizers such as castor oil, mineral oil, corn oil, sesame oil and propylene glycol, alone or in admixture with a drying oil such as soybean oil (d) surface-active ingredients such as polyoxyethylene sorbitan derivatives and sulphated fatty alcohols and (e) cellulose acetate. Specifications 762,229 and 764,342 are referred to.ALSO:A coated solid medicament has the coating material in the form of a physiologically acceptable composition consisting essentially of a water permeable combination of a water-soluble or water-dispersible wax (A) and a polyvinylpyrrolidone vinyl acetate copolymer (B). The waxes are polyethylene glycols of melting point at least 50 DEG C., glyceryl monostearate and diglycol stearate, or mixtures thereof. The copolymers contain 30-70, and preferably 60% of polyvinylpyrrolidone and 70 to 30%, and preferably 40% of vinyl acetate. Optional ingredients are (a) dyes, lakes and pigments, (b) water-insoluble waxes such as beeswax, lanolin, stearic acid, cocoa butter and cetyl alcohol (C) (c) plasticizers such as castor oil, mineral oil, corn oil, sesame oil and propylene glycol, alone or in admixture with a drying oil such as soybean oil (D) (d) surface-active agents such as polyoxyethylene sorbitan derivatives and sulphated fatty alcohols and (e) an antisticking agent which is cellulose acetate. The compositions contain 10 to 25 grms. of (A), 2 to 10 grms. of (B), not more than 1 grm. of (C) and not more than 2 grms. of (D) per 100 ml. of the fluid composition which is prepared by dissolving the components in a non-aqueous solvent such as acetone, ethanol or mixtures thereof. The finished coat contains 50-92% of (A), 8 to 50% of (B) and not more than 5% of the optional components. Specifications 762,229 and 764,342 are referred to.
