Definitions
- the present invention relates to a medicament preparation for the application of active substances in the area of the oral cavity or the oral mucosa. It relates in particular to a preparation that is flat and designed as a film, paper or wafer-like dosage form.
- DE-OS 27 46 414 which describes a film-like band of active substance, binder and other auxiliaries, in which, due to homogeneous thickness and density, there is a direct connection between a unit length of the band and the dose of active substance contained therein, can be regarded as fundamental for this dosage form .
- the advantages of continuous dosing were also recognized by other applicants and described in special individual variants.
- DE-PS 36 30 603 claims a flat carrier material e.g. in the form of a release paper with a coating containing the active substance, the latter being subtracted from the carrier material in doses after being divided up into dose units.
- a flat, film-like or paper-like active ingredient carrier enables a faster onset of action than the application of conventional dosage forms, such as tablets.
- Tablets are usually designed for drug release after swallowing in the gastrointestinal tract. Ordinary, rapidly disintegrating tablets release their active ingredient in the stomach. The disintegration of the dosage form is a prerequisite for the release of the active ingredient.
- the disintegration of a tablet in the fluids of the gastrointestinal tract is often a multi-stage process. If the tablet has a coating, it must first disintegrate and expose the compact.
- the latter are suitable for introducing active substances into the organism more quickly than with tablets, and can advantageously be used when a quick onset of action is necessary or particularly desirable, for example when administering analgesics, antiallergics, antitussives, antiemetics, active substances against Angina, migraines, hypotension, etc.
- the object of the present invention is therefore to create a medicinal preparation based on and with the general advantages of flat, film-like or paper-like active substance carriers, which, however, in addition, through the combination with a special active substance, also have additional economic and / or therapeutic advantages over medicament preparations thereof Active ingredient based on conventional dosage forms such as tablets.
- a medicinal preparation is provided on the basis of a flat, film, paper or wafer-like active ingredient carrier which contains apomorphine or one of its therapeutically suitable salts as the active ingredient.
- a pharmaceutical preparation according to claim 1 is, as will be explained in the following, a conventional oral dosage form for the administration of apomorphine far superior both from an economic as well as from a therapeutic point of view and is particularly suitable for the therapy of Parkinson's disease.
- apomorphine a potent dopamine agonist
- apomorphine must be injected subcutaneously for this purpose, since it is hardly bioavailable after oral administration, i.e. it only appears to a very small extent in the bloodstream of a few percent of the dose taken.
- the reason for the lack of bioavailability probably lies in the extensive breakdown of the substance during the first passage through the liver after gastrointestinal absorption ("first pass effect").
- One way to circumvent the first-pass effect in the case of oral administration is to induce the active ingredient to be absorbed on the oral mucosa.
- Active substance that enters the blood here does not first have to pass through the portal vein system and thus in concentrated form through the liver metabolizing the active substance in order to get into the central body circulation.
- a prerequisite for buccal or sublingual application is the sufficient permeability of the oral mucosa for the active substance, taking into account the necessary dose. The permeability in turn depends to a large extent on the physicochemical properties of the active ingredient.
- buccal or sublingual administration of apomorphine appears to be very desirable for the patients because of the injections to be avoided.
- apomorphine with the aid of a pharmaceutical preparation according to claim 1 is completely different.
- This dosage form can be brought into direct contact with the oral mucosa during application. Due to the flat design, about half of the already large surface of the dosage form is immediately on the mucosa immediately after application.
- the released apomorphine therefore finds two particularly favorable factors for entry into the body, namely a short diffusion distance and a large diffusion area. This reduces the amount of apomorphine that is swallowed, which would not be particularly problematic with other active ingredients. In the case of apomorphine, however, the swallowing of active ingredient should be avoided or reduced as far as possible, since swallowed apomorphine remains ineffective for the reasons set out above.
- test person showed the superiority of an apomorphine-containing film over an apomorphine-containing tablet.
- An improved contact of the pharmaceutical preparation according to the invention with the oral mucosa can be brought about by the selection of the auxiliary substances.
- pharmaceutically customary, orally administrable auxiliaries have mucosal properties.
- mucoadhesive substances are polyacrylic acid, carboxylmethyl cellulose, tragacanth, alginic acid, gelatin, hydroxymethyl cellulose, methyl cellulose and gum arabic.
- various non-mucoadhesive substances are known to also form mucoadhesive properties in certain mixing ratios.
- An example of such a mixture is glycerol monooleate / water in the ratio 84:16 (Engström et al., Pharm. Tech. Eur. 7 [1995], No. 2, pages 14-17).
- a two- or multi-layer structure of the dosage form of the medicinal preparation according to the invention is to be preferred, only one layer, which should come into contact with the mucous membrane when the preparation is applied, to be provided with mucoadhesive properties. This prevents the preparation from sticking together different parts of the mucous membrane, which would lead to considerable discomfort during use.
- the amount of active ingredient or the proportion of the administered active ingredient dose which is absorbed in the preparation according to the invention depends not only on the contact area and the perme bailiness of the mucous membrane, but also on the contact time.
- auxiliaries can be, for example, film-forming polymers with low water solubility, such as ethyl cellulose, cellulose acetate, highly hydrolyzed polyvinyl alcohol and many others.
- apomorphine usually leads to undesirable side effects. First of all there are nausea, vomiting and a drop in blood pressure. These side effects can be seen as serious and therapy-limiting. However, it is known that the simultaneous administration of antiemetic dopamine antagonists such as metoclopramide, but especially domperidone, can prevent or alleviate the occurrence of these side effects without losing the anti-Parkinson effect of apomorphine.
- antiemetic dopamine antagonists such as metoclopramide, but especially domperidone
- a further preferred embodiment of the present invention therefore contains apomorphine in combination with a dopamine antagonist in a combination as active ingredients.
- Production examples of the pharmaceutical preparation according to the invention are given below:
- H 2 0 Place H 2 0 in a heatable, evacuable batch vessel and disperse Ti0 2 in it.
