摘要:
The present invention relates to a method of producing a film forming blend of different acyl gellan gums with starch having similar textural and functional properties compared to gelatin. Films prepared using such blends have a high modulus and excellent strength and elongation. The present invention also relates to soft capsules prepared using such blends or films, which have good sealability.
摘要:
A process for making a free-flowing, compressible powder by spraying a selected amount of an aqueous solution of polyvinylpyrrolidone onto a fluid bed containing a predetermined admixture of starch and polyvinylpyrrolidone therein, and drying. An active-containing tablet then is provided by adding an active material, optionally with a lubricant, to such powder, and compressing the admixture into a commercially acceptable tablet.

摘要:
A pH-dependent, controlled-release, drug delivery composition is described herein which includes:(a) a complex between poly(maleic diacid-alkyl vinyl ether) and polyvinylpyrrolidone, or their equivalents, and(b) an effective amount of a pharmaceutical medicament.
摘要:
A controlled release, drug-delivery tableted composition comprising, by weight, an uncrosslinked or crosslinked polymer of (a) about 5-40% of a vinyl amide, (b) about 10-70% of (meth)acrylic acid, (c) about 5-40% of a long chain alkyl (meth)acrylate or acrylamide, and (d) about 0-60% of a lower alkyl (meth)acrylate, and a pharmaceutical medicament.
