Certain water-soluble copolymers prepared from divinyl ether and maleic anhydride have been found to suppress virus growth. Administration of said copolymers not only suppresses growth in infected animals but also increases resistance to virus infection in healthy animals by stimulating the production of interferon.

Water-soluble bad-tasting drugs and vitamins are put into chewable tablet form wherein the drugs and vitamins have a pleasant taste and are readily available upon ingestion. A water solution or water-alcohol solution of the bad-tasting substance is absorbed into rice endosperm using about enough solution for complete hydration or slightly less, followed by drying. Precooked rice endosperm can also be used. The drugs include phenothiazine tranquilizers and barbiturates and the vitamins include thiamin, niacinamide and pyridoxine. The water-soluble substance may constitute up to 60 percent of the finished product, with the rice endosperms, which may be previously comminuted, making up the balance. The pleasant tasting chewable tablets contain the bad tasting substance with the bad taste masked, conventional chewable tablet base constituents for the tableting of the rice endosperm-drug particles being combined with the treated rice endosperms.

WATER-SOLUBLE BAD-TASTING DRUGS AND VITAMINS ARE PUT INTO CHEWABLE TABLET FORM WHEREIN THE DRUGS AND VITAMINS HAVE A PLEASTANT TASTE AND ARE READILY AVAILABLE UPON INGESTION. A WATER SOLUTION OR WATER-ALCOHOL SOLUTION OF THE BAD-TASTING SUBSTANCE IS ABSORBED INTO RICE ENDOSPERM USING ABOUT ENOUGH SOLUTION FOR COMPLETE HYDRATION OR SLIGHTLY LESS, FOLLOWED BY DRYING. PRECOOKED RICE ENDOSPERM CAN ALSO BE USED. THE DRUGS INCLUDE PHENOTHIAZINE TRANQUILIZERS AND BARBITURATES AND THE VITAMINS INCLUDE THIAMIN, NIACINAMIDE AND PYRIDOXINE. THE WATER-SOLUBLE SUBSTANCE MAY CONSTITUTE UP TO 60% OF THE FINISHED PRODUCT, WITH THE RICE ENDOSPERMS, WHICH MAY BE PREVIOUSLY COMMINUTED, MAKING UP THE BALANCE. THE PLEASANT TASTING CHEWABLE TABLETS CONTAIN THE BAD TASTING SUBSTANCE WITH THE BAD TASTE MASKED, CONVENTIONAL CHEWABLE TABLET BASE CONSTITUENTS FOR THE TABLETING OF THE RICE ENDOSPERM-DRUG PARTICLES BEING COMBINED WITH THE TREATED RICE ENDOSPERMS.

This application discloses tablets having a harder outer shell which inhibits penetration of liquid into the interior of the tablet, and a softer interior which quickly liquifies when the tablet and shell are broken into pieces and contacted by the liquid. The tablet has particular utility as a chewable tablet which resists absorption of moisture but which quickly liquifies and melts in the mouth within seconds after mastication, even if the tablet contains considerable amounts of active ingredients that do not dissolve well or at all in the mouth. Also disclosed are agglomerates from which the tablets are directly compressed, and processes for making the agglomerates and tablets. The tablets contain increased quantities of active ingredients of up to about 75% by weight. The excipient or base material of the tablet is made from carbohydrates including dextrose, dextrose monohydrate, maltodextrin, fructose, sucrose, lactose, maltose and xylose held together by small quantities of a carbohydrate binder such as maltodextrin. Tablets according to the invention can contain active ingredients such a pharmaceuticals (e.g., antacids, analgesics, cough medicine, drugs, etc.) breath sweeteners, vitamins and dietary supplements, to name a few.

摘要:
The invention relates to a process for the production of pharmaceutical preparations exhibiting delayed release of an active substance which comprises intimately mixing a more slowly absorbable therapeutically-active substance with one which is more rapidly absorbable, one of these therapeutically-active substances being present in the non-solid state in which the other one is homogeneously incorporated, solidifying the mixture obtained and forming it into a solid pharmaceutical preparation. The invention also relates to a process for the stabilization of vitamins in a mixture containing certain substituted xanthines which are also suitable in the afore-mentioned process by homogeneously incorporating one component in the other one which is in the non-solid state, and to preparations comprising a combination of a vitamin stabilized with one of said substituted xanthines.
