摘要:
The invention relates to an oral, multiparticle pharmaceutical dosage form containing pellets, the size of which ranges from 50 to 2500 μm and which essentially consist of: a) an inner matrix layer containing an active substance which is a peptide or a protein, including the derivatives or conjugates thereof, and which is embedded in a matrix consisting of a polymer with mucoadhesive effect, and b) an outer film coating essentially consisting of an anionic polymer or copolymer, which can be optionally formulated with pharmaceutically conventional adjuvants, more particularly softening agents.
摘要:
The invention relates to a partly neutralized anionic (meth)acrylate copolymer consisting of radically polymerized units containing 25-95% by weight (meth)acrylic acid C1 to C4 alkylesters and 5-75% by weight (meth)acrylate monomer with an anionic group, wherein 0.1 to 25% contained anionic groups are neutralized by a base. Said invention is characterized in that said base is embodied in the form of an cationic organic base whose molecular weight is greater than 150. A medical form containing said partly neutralized anionic (meth)acrylate copolymer and the use of said partly neutralized anionic (meth)acrylate copolymer for producing a medical form rapidly releasing an active substance having a determined pH value are also disclosed.

摘要:
The invention relates to an aqueous medium containing an amino(meth)acrylate polymer or copolymer which is not soluble in dematerialised water, characterized in that the medium has a content of an aqueous phase of at least 60% by weight and a content of up to 40% by weight of solids comprising the amino(meth)acrylate polymer or copolymer, whereby the aqueous phase is charged by a sufficient amount of carbon dioxide that effects the amino(meth)acrylate polymer or copolymer to be present in solute form in the medium. The aqueous medium may be used beneficially as a coating or binding solution for the spray coating or binding of pharmaceutical compositions or nutraceutical compositions or cosmetical compositions.
摘要:
The present invention provides a solid dosage form including an inner coating located between a core containing a pharmaceutically active ingredient and an outer enteric coating; wherein the inner coating includes a partially neutralized anionic polymeric material, and at least a carboxylic acid having 2 to 16 carbon atoms the salts thereof or mixtures of the acid and its salt; wherein the outer coating includes an anionic polymeric material which is less or not at all neutralized than the material of the inner coating.
摘要:
The invention provides a gastric resistant, enteric-coated solid dosage form including a core containing a pharmaceutically active ingredient, an inner coating for the core, and an outer enteric coating. The inner coating comprises an anionic polymeric material or a water-soluble neutral polymeric material, and further comprises a water soluble inorganic salt which is not a carbonate or bicarbonates. The outer enteric coating comprises an anionic polymeric material which is less neutralized than the polymeric material comprising the inner coating and disintegrates rapidly at a pH of 5.5 to 7.0 upon entering the small intestine.
