Definitions
- the present invention relates to topical medicaments for the treatment of aphthae, in particular topical medicaments, which are in film form.
- aphthous ulcer refers to a painful lesion of the mucous membrane limited by an inflammatory margin, and cancers of the ulcer with whitish fibrin, small aphthae less than one centimeter in diameter, usually healing within one to two weeks In rare cases, however, aphthae may be larger than one centimeter, up to 3 cm in diameter.
- These cancers may persist for weeks or even months and heal only with scarring, and aphthae predominantly occur on the mucous membrane of the patient Gums, tonsils, and tongue are less likely to affect the mucous membranes of the genitalia of the aphthae.Aphtics are painful.The painfulness of an aphid is less correlated with its size, rather, it depends on the site where the aphthea occurs. Eating and swallowing make the pain noticeable chtigen Aphten the
- analgesics such as lidocaine, polidocanol or benzydamine are offered in the form of sprays, gargles, gels or ointments.
- astringents such as rhubarb root extract, myrrhine tincture, silver nitrate, phenol sulfonic acid compounds, the cresol-sulfonic acid condensate, policresulene, zinc sulfate or hydrogen administered peroxide solution.
- Treatment of aphthous ulcers may be the anti-inflammatory
- Triamcinolone acetonide may be mentioned.
- Alternative anti-inflammatory agents used in the treatment of aphthae include, for example, Australian Tea Tree Oil, Melissa Extract, and Camomile or Sage Tea.
- aphthae Diseases that should be treatable with hyaluronic acid are called aphthae.
- the document DE 696 13 840 T1 relates to tablets which have a non-anesthetic active substance core with a long-term effect, which is provided with an anesthetic coating.
- the core may comprise a hydrophilic shear layer comprising a hydrophilic polymer such as
- Carbopol may contain.
- a drug-containing polymer film for the treatment of aphthae is mentioned, which absorbs moisture from the buccal mucosa and adheres to the membrane surface.
- the patent DE 694 29 964 T2 discloses solid preparations for the treatment of mucous membrane diseases. These solid preparations are compacts containing a homo- or copolymer of acrylic acid, a cellulose ether and gelatin.
- Specified orodispersible tablets that are to be attached directly to the lesion of a mucous membrane, so that their application to the patient will certainly be painful.
- a plaster for the treatment of aphthae in which a film-shaped drug is fixed by means of an over plaster in the mouth.
- Polymers are used. The material for the production of the patch remains fixed in the mouth and should slowly dissolve in saliva.
- Mouthwash, tinctures and pastes have the disadvantage that they adhere only for a short time on the aphthae.
- Adhesive tablets have the disadvantage that their application is painful for the patient, because they are hard compacts that exert pressure on the aphthae.
- a topical drug that is easy to administer, that lingers on the aphthy for a long time and whose use does not cause even more pain to the patient.
- the present invention therefore an object of the invention to provide a topical medicament for the treatment of aphthae, which delivers one or more active ingredients continuously, does not melt in the mouth and in which it is ensured that the active ingredient or active ingredients are sufficiently distributed in the oral mucosa, and in the application of skin irritation are largely avoided.
- a topical drug in the form of a film-form dosage form which is a water-swellable or
- water-soluble polymer or polymer mixture and at least one suitable for the treatment of aphids drug.
- film-shaped dosage form according to the invention is easy to apply to an aphid, can stay there and continuously release the active substance contained in it, since it dissolves only over a longer period of time, ie over a period of more than one hour.
- the application of the dosage form according to the invention prepares the patient no additional pain.
- the invention relates to a topical medicament for the treatment of aphths, which is present as a film-like dosage form.
- the invention relates to a method for producing the film-form administration form for the treatment of aphthae.
- the invention relates to the use of the
- Filmformigen dosage form for the treatment of aphthae for the treatment of aphthae.
- the invention relates to a method for the treatment of aphthae with the aid of the film-form administration forms.
- the topical medicament for the treatment of aphthae is in the form of a film-shaped dosage form.
- the film-shaped dosage form comprises a water-swellable or water-soluble polymer or a water-swellable or water-soluble polymer
- the film-shaped dosage form according to the invention has such a self-tackiness that a permanent contact with the mucous membrane
- the film-shaped dosage form comprises a stretchable polymer film, wherein the at least one active ingredient is dissolved or finely distributed in the polymer or polymer mixture.
- the water-swellable or water-soluble polymer may be a natural, ie a naturally occurring, polymer. Natural polymers within the meaning of the present specification also include polymers based on naturally occurring polymers modified by chemical and / or physical treatment (s).
- the water-swellable or water-soluble polymer is a fully synthetic polymer. Fully synthetic polymers may be preferable to natural polymers because of their swelling and / or solubility properties when certain embodiments of the film-shaped dosage form are to have certain properties.
- the film-shaped dosage form comprises a water-swellable or water-soluble polymer mixture at least one of the polymers of the polymer mixture is a water-swellable or water-soluble polymer.
- the at least one water-swellable or water-soluble polymer of the water-swellable or water-soluble polymer mixture is a fully synthetic polymer.
- the water-swellable or water-soluble polymer mixture may comprise a plurality of water-swellable or water-soluble polymers, preferably a plurality of fully synthetic, water-swellable or water-soluble polymers.
- the film-form dosage form may contain at least one water-swellable or soluble polymer selected from the group of polymers including dextran, cellulose derivatives, polyacrylic acid, polyacrylates, polyethylene oxide polymers, polyacrylamides, polyethylene glycol, collagen, alginates, pectins, tragacanth , Chitosan,
- Carrageenan and natural gums includes.
- the cellulose derivatives may be selected from the group comprising carboxymethylcellulose, ethylcellulose and propylcellulose.

- Polymer blend at least one active ingredient and optionally at least one pharmaceutically acceptable excipient may be spread onto a support material. Thereafter, the solvent or suspending agent may be removed from the spread mixture to obtain a polymer film from which the film-shaped dosage forms can be singulated.
- the invention comprises the use of the above-described film-shaped administration forms for the treatment of aphthae.
- one of the film-shaped administration forms can be applied to the aphtha to be treated, so that the aphtha is covered by the film-shaped administration form. Because of your
- the film-shaped dosage form remains in contact with the mucous membrane and releases the at least one active ingredient contained in it into the affected mucous membrane as well as to the environment of the aphthae.
- the film-shaped dosage form dissolves over a longer period of time.
