Definitions
- the invention relates to the use of a copolymer for the production of a pharmaceutical form which contains a peptide or protein as an active ingredient, and to the pharmaceutical form obtained in accordance with the use.
- US 5,591, 433, US 5,629,001, US 5, 783,193 and US 6,174,529 B1 describe the oral administration of therapeutically active proteins.
- the therapeutically active proteins it can be e.g. B. to vaccines (vaccines), proteins for the treatment of autoimmune diseases or to proteins that are intended to prevent an abutment of foreign tissue in organ transplants.
- the proteins are on cores (Nonpareils) together with stabilizing substances such as.
- B. formulated lactose, mannitol or trehalose which should provide protection during the subsequent coating with a polymeric coating agent and during passage through the gastrointestinal tract.
- Only aqueous emulsion polymers are suitable as polymeric coating agents. Suitable polymers are e.g. B.
- hydroxypropyimethyl cellulose acetate succinate or EUDRAGIT® L 30 D a copolymer of 50 wt .-% methyl methacrylate and 50 wt .-% methacrylic acid.
- the polymer can be used together with auxiliaries such as. B. 0 to 30 wt .-% plasticizer, 0 to 3 wt .-% talc and 0 to 0.0025 wt .-% antifoam, e.g. As silicone or sorbitan sesquioleate can be used.
- the coating temperatures should be between 30 and 50 ° C.
- EP 0 704 207 A2 describes thermoplastic materials for pharmaceutical casings soluble in intestinal juice. These are copolymers of 16 to 40% by weight of acrylic or methacrylic acid, 30 to 80% by weight of methyl acrylate and 0 to 40% by weight of other alkyl esters of acrylic acid and / or methacrylic acid.
- EP 0 704 208 A2 describes coating agents and binders for intestinal juice-soluble pharmaceutical casings. These are copolymers of 10 to 25% by weight of methacrylic acid, 40 to 70% by weight of methyl acrylate and 20 to 40% by weight of methyl methacrylate. In addition to single-layer coatings, the description also mentions multi-layer coating systems. These can consist of a core, e.g. B. contains a basic or a water-sensitive active ingredient, have an insulating layer made of another coating material, such as cellulose ether, cellulose ester or a cationic polymethacrylate z. B. of type EUDRAGIT®, u. a. also EUDRAGIT® RS and RL, and are then additionally provided with the casing-soluble coating mentioned above.

- an insulating layer made of another coating material, such as cellulose ether, cellulose ester or a cationic polyme
- Example 4 of EP 0 704 208 A2 describes the active ingredient release from pellets containing bisacodyl with a copolymer coating of 70% by weight methyl acrylate, 20% by weight methyl methacrylate and 10% by weight methacrylic acid. 99% of the active ingredient is released at pH 6.8 in just 45 minutes.
- the dissolution behavior of glass beads coated with copolymer is shown in further examples. From pH 7.0, a steep curve is observed. The release of methylene blue from appropriately coated tablets is described in further examples.
- Tablets with a copolymer coating of 65% by weight methyl acrylate, 25 % By weight of methyl methacrylate and 10% by weight of methacrylic acid did not dissolve in pH 6.8 buffer solution after 60 min, but disintegrated within 50 min at pH 7.5.
- Coatings made from EUDRAGIT® L 30-D, a copolymer of 50% by weight of ethyl acrylate and 50% by weight of methacrylic acid also show an at least partially undesirable early release of active ingredient. This is particularly the case with active substances, the proteins or peptides being critical, since these are then exposed to the action of the proteolytic enzymes present in these sections of the intestine.
- Another problem with active substances that are proteins or peptides is a possible denaturation of their structure. This can occur in whole or in part, particularly during storage of the pharmaceutical form due to acid groups present in the polymer coating or due to auxiliary substances such as plasticizers.
- a pharmaceutical form should therefore be provided which is particularly suitable for active substances which are proteins or peptides.
- the object is achieved by using a copolymer or a mixture of copolymers of C 1 -C 4 -alkyl esters of acrylic or methacrylic acid, containing 5 to 25% by weight of methacrylic acid, alone or based on the mixture, as a coating agent for a pharmaceutical form , consisting of a core containing a pharmaceutical active ingredient which is a peptide or a protein.

- methyl acrylate is apparently particularly critical. If this rises to above 68% by weight, this promotes rapid dissolution of the polymer coatings even at pH values around 6.8, which is undesirable for. In the range of 50 to 68. preferably 60 to 67% by weight of methyl acrylate, the desired release characteristic is obtained in combination with the likewise critical content of 5 to 20% by weight, preferably 8 to 12, methacrylic acid.

- the pharmaceutical form can have a polymer coating of a copolymer of 50 to 68% by weight of methyl acrylate, 27 to 45% by weight of d- to C -alkyl esters of acrylic or methacrylic acid and 5 to 20% by weight of methacrylic acid.

- the active ingredient cores (pellets) can be obtained after drying and sieving in the desired size fraction (e.g. 0.7 to 1 mm). This process is referred to as "powder layering
- Proteins or peptides are a group of organic macromolecules made up of amino acids linked together by peptide bonds.
- the order in which the As are linked together results in the so-called primary structure of the proteins. If parts of such peptide chains spatially connect with each other (e.g. through the formation of hydrogen bridges), spiral-like structures ( ⁇ -helix) or leaflet-like forms (ß-folding plate structure) can arise, which are referred to as secondary structures.

- Antibodies are protein compounds generated in the organism from the group of immunoglobulins; they stick together (agglutination) with penetrated foreign organic compounds (antigens) to form a harmless complex. Antibodies are produced in the lymph nodes of more developed animals and humans. When it comes to immunity, enough antibodies are available or are produced more quickly. If there are too many antibodies, allergy symptoms can occur with sudden agglutination.
- the greatest therapeutic spread is IgG or monoclonal antibodies, which are produced by cells that are derived from a mother cell.
- the (oral) pharmaceutical form described can be in the form of a coated tablet, in the form of a tablet made of compressed pellets or in the form of pellets which are placed in a capsule, e.g. B. from gelatin, starch or cellulose derivatives are filled.
- auxiliaries can be used in a manner known per se. These auxiliaries can be contained in the core or in the coating agent. Drying agents (non-stick agents): Drying agents have the following properties: They have large specific surfaces, are chemically inert, are easy to pour and have fine particles. These properties reduce the stickiness of polymers which contain polar comonomers as functional groups.
