Abstract
Abstract A solid pharmaceutical preparation for administration in dosage unit form comprising a therapeutically effective cardiac glycoside, whereby each dosage unit is to comprise a plurality of bodies, each of said bodies having a pharmaceutically inert core and a layer thereon containing the glycoside and a polymer insoluble in gastric juice and soluble in intestinal juice, a process for preparing such preparation and a method of treatment employing the same.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
A pharmaceutical preparation comprising a cardiac glycoside in combination with a polymer, characterized in that said pharmaceutical preparation is in the form of a plurality of small bodies, each body comprising a fraction of a therapeutically effective dosage of the cardiac glycoside, whereby each body has a core made up of pharmaceutically indifferent material, and on said core a layer made up of a composition comprising the cardiac glycoside and an anionic carboxylic polymer being difficultly soluble or insoluble below a given pH value in the interval of pH 4-7.5 but being soluble at a pH above said given value.
Claim 2
Dependent Claim
100 words
A pharmaceutical preparation comprising a cardiac glycoside in combination with a polymer, characterized in that said pharmaceutical preparation is in the form of a plurality of small bodies, each body comprising a fraction of a therapeutically effective dosage of the cardiac glycoside, whereby each body has a core made up of pharmaceutically indifferent material, and on said core a layer made up of a composition comprising the cardiac glycoside and an anionic carboxylic polymer being difficultly soluble or insoluble below a given pH value in the interval of pH 4-7.5 but being soluble at a pH above said given value.
Claim 3
Dependent Claim
25 words
A solid pharmaceutical preparation according to claim 1 characterized in that the layer is a layer applied by spraying a solution of the components thereof.
Claim 4
Dependent Claim
102 words
A process for preparing a pharmaceutical preparation comprising a cardiac glycoside in combination with a polymer, characterized in that said pharmaceutical preparation is given the form of a plurality of small bodies, each body comprising a fraction of a therapeutically effective dosage of the cardiac glycoside, by providing a large number of cores made up of pharmaceutically indifferent material, with a layer made up of a composition comprising the cardiac glycoside and an anionic carboxylic polymer being difficultly soluble or insoluble below a given pH value in the interval of pH 4-7.5 but being soluble at a pH above said given value.
Claim 5
Dependent Claim
102 words
A process for preparing a pharmaceutical preparation comprising a cardiac glycoside in combination with a polymer, characterized in that said pharmaceutical preparation is given the form of a plurality of small bodies, each body comprising a fraction of a therapeutically effective dosage of the cardiac glycoside, by providing a large number of cores made up of pharmaceutically indifferent material, with a layer made up of a composition comprising the cardiac glycoside and an anionic carboxylic polymer being difficultly soluble or insoluble below a given pH value in the interval of pH 4-7.5 but being soluble at a pH above said given value.
Claim 6
Dependent Claim
22 words
A process according to claim 3 characterized in that the outer layer is applied by adding a solution of the components thereof.
Claim 7
Dependent Claim
15 words
A process according to claim 4 characterized in that the solution is applied by spraying.
Claim 8
Dependent Claim
21 words
A process according to claim 4 or 5 characterized in that the outer layer is applied in a fluid bed apparatus.
