Definitions
- the invention relates to an agent containing at least one active ingredient, with which an exact, controlled and controllable release of the at least one active ingredient is possible.
- Active substances are understood to mean low molecular weight, organic compounds which have a desired effect after their release from the agent, in particular a pharmacological or biocidal effect.
- Active pharmaceutical ingredients are offered in a variety of dosage forms, which should make it possible for the active pharmaceutical ingredient to be able to develop its effect at the desired location in the organism at the desired time and in the desired dosage. These goals could not always be achieved with the known dosage forms.
- This object is achieved according to the invention by a film containing the at least one active ingredient, which is at least partially degraded under the conditions of the site of action.
- the film preferably consists of biological material, for example of an optionally partially degraded polypeptide, in particular of gelatin.
- the biological material is preferably degraded enzymatically at the site of action and thus releases the at least one active ingredient stored in it.
- the biological material of the film can be modified, for example by aqueous polymer latices or polymer dispersions, by water-soluble, optionally crosslinkable polymers or copolymers or protein derivatives. Examples of this are in Res. Discl. 38 957 (1996) on p. 598, Chapter II A and Chapter II C described, the z. B. contain a polyacrylamide, a polyacrylic acid derivative, a polyvinylpyrrolidone, a polyvinyl alcohol, a polyvinylimidazole, a polyethylene oxide, a polystyrene sulfonic acid or a cellulose derivative.
- the biological material can be further hardened to different degrees, that is, cross-linked, e.g. B.
- the films made of biological material, especially gelatin have many advantages: They can be any biological material, especially gelatin. They can be any biological material, especially gelatin.
- the production takes place in particular in that the biological material on which the films are based is poured as an aqueous solution onto a carrier film by means of a suitable pouring device and is removed after drying. This is advantageously carried out continuously with a cascade or a curtain caster.
- Suitable carrier films are, in particular, cellulose acetate film and paper coated on both sides with polyethylene, both of which are known as carrier materials for photographic materials. Films made of polyester (PET or PEN) and polycarbonate are also suitable.
- the carrier films are not equipped with substrate or adhesive layers, which are known to bind the subsequent cast layers to the carrier film, since the cast layer is to be removed after production.
- the active ingredients are added to the casting solutions and thus incorporated into the later films. An exact dosage is possible. Furthermore, the active ingredient z. B. distributed in a specific environment, for example in a solution in a high-boiling organic solvent, which is in the aqueous
- Casting solution is emulsified.
- the active ingredient can also be introduced in the form of a loaded latex.
- a latex is impregnated or loaded with the water-soluble active ingredient. This insertion method is for photographic color couplers in Res. Discl. 38 957 (1996), p.
- the film according to the invention can consist of several layers. This is advantageous if at least two active ingredients which are incompatible with one another are to be contained in a film, since they can be introduced in different layers. It is also possible to provide active substances in different concentrations in the different layers, in order to enable a targeted release of the active substance in different amounts during later use.
- the film can be cut into small and very small parts and applied in this way, be it in one of these parts containing solid or liquid dosage form, for example in a tablet or in a juice.
- the release occurs through degradation of the film substance, in the case of gelatin film through enzymatic degradation, in particular through an enzyme of the organism that is to be treated with the active ingredient, for example with trypsin.
- Betaxolol and 90.0 g of olive oil are dissolved in 80 g of ethyl acetate and emulsified in an aqueous solution of 6.0 g of gelatin, 350 g of water and 0.5 g of dodecylbenzenesulfonate using an emulsifier at 40 ° C. within 12 minutes , The ethyl acetate is evaporated and an O / W emulsion is obtained, which is made up to 500 g with water.
- emulsion 1 160 g of emulsion 1 are mixed at 40 ° C. with 66 g of 20% by weight gelatin, 90 g of water and 4.0 g of 10% by weight dioctyl sulfosuccinate, sodium salt solution (wetting agent) and water to 350 g filled up.
- pouring solution 2 160 g of emulsion 1 are mixed at 40 ° C. with 66 g of 20% by weight gelatin, 90 g of water and 4.0 g of 10% by weight dioctyl sulfosuccinate, sodium salt solution (wetting agent) and water to 350 g filled up.
- pouring solution 2 160 g of emulsion 1 are mixed at 40 ° C. with 66 g of 20% by weight gelatin, 90 g of water and 4.0 g of 10% by weight dioctyl sulfosuccinate, sodium salt solution (wetting agent) and water to 350 g filled up.
- Pouring solution 2 160 g of e
- 160 g of emulsion 2 are mixed at 40 ° C. with 70 g of 20% by weight gelatin, 90 g of water and 4.0 g of 10% by weight dioctyl sulfosuccinate, sodium salt solution (wetting agent) and water Replenished 350 g.
- a cascade caster known from the manufacture of photographic materials is used to add a non-subbed polyethylene terephthalate film
- the application is chosen so that after drying at 50 ° C a dressing of 3 layers with layer applications of
- Sample 2 contains metipranolol and betaxolol
- the test shows that the pieces of film selectively release the active substances one after the other by enzymatic degradation.
