An oral administration form for an acid-labile active compound selected from the group consisting of an acid-labile active proton pump inhibitor, a salt of an acid-labile proton pump inhibitor with a base and a hydrate of a salt of an acid-labile proton pump inhibitor with a base, the form comprising a pharmaceutical auxiliary and a plurality of individual active compound units, wherein the acid-labile active compound in the individual active compound units is surrounded by a mixture of at least one sterol and at least one polymer, by at least one fatty alcohol or by a mixture of at least one fatty alcohol and at least one polymer and/or at least one sterol.
A method for overcoming a need for an enteric layer in preparing a stable oral administration form for an acid-labile active compound selected from the group consisting of an acid-labile proton pump inhibitor, a salt of an acid-labile proton pump inhibitor with a base and a hydrate of an acid-labile proton pump inhibitor with a base, which comprises surrounding a plurality of individual units of the acid-labile active compound by a) a mixture of at least one sterol and at least one polymer, b) at least one fatty alcohol, or c) a mixture of at least one fatty alcohol and at least one polymer and/or at least one sterol.
An active compound unit comprising an acid-labile active compound, which is a proton pump inhibitor, a salt of an acid-labile proton pump inhibitor with a base or a hydrate of a salt of an acid-labile proton pump inhibitor with a base, wherein the acid-labile active compound is surrounded by a mixture of at least one sterol and at least one polymer, by at least one fatty alcohol or by a mixture of at least one fatty alcohol and at least one polymer and/or at least one sterol.
A composition comprising a spray-dried suspension of an acid-labile proton pump inhibitor, a salt of an acid-labile proton pump inhibitor with a base or a hydrate of a salt of an acid-labile proton pump inhibitor with a base, in a solution of at least one sterol and at least one polymer in a suitable solvent.
A composition comprising a spray-congealed suspension of an acid-labile proton pump inhibitor, a salt of an acid-labile proton pump inhibitor with a base or a hydrate of a salt of an acid-labile proton pump inhibitor with a base, in a solution of at least one fatty alcohol or a mixture of at least one fatty alcohol and at least one polymer and/or sterol in the fatty alcohol.
A pharmaceutically acceptable composition comprising an effective amount of a) an acid-labile proton pump inhibitor or a salt of an acid-labile proton pump inhibitor with a base or a hydrate of the salt of an acid-labile proton pump inhibitor with a base together with b) a sterol and c) a polymer, and which is a spray-dried suspension of (a) in a suitable-solvent solution of the sterol and the polymer.
A pharmaceutically acceptable composition comprising an effective amount of a) an acid-labile proton pump inhibitor or a salt of an acid-labile proton pump inhibitor with a base or a hydrate of a salt of an acid-labile proton pump inhibitor with a base, together with b) a fatty alcohol or c) a mixture of a fatty alcohol, a polymer and/or a sterol, and which is a spray-congealed suspension of (a) in the fatty alcohol or in a solution of the polymer and/or sterol in the fatty alcohol.
