Definitions
- the present invention relates to transdermal therapeutic systems (TTS) for the administration of the active ingredient oxybutynin. It also relates to a production process for active ingredient layers of transdermal therapeutic systems containing oxybutynin.
- TTS transdermal therapeutic systems
- Oxybutynin is an anticholinergic and spasmolytic, which is mainly used to treat bladder dysfunction, especially urge to urinate, incontinence or nocturia.
- This active ingredient is usually administered orally as oaybutynin hydrochloride, for example in the form of tablets. Capsules or syrup.
- transdermal therapeutic systems have been described in the literature which are intended to enable the administration of this active substance via the skin.
- ALZA US 5,500,222, US 5,411,740, US 5,900,250 and EP 721 349
- Theratech US 5,834,010
- Schwarz Pharma AG DE 198 12 413 Cl
- enhancers are associated with an increased risk of skin irritation.
- the addition of enhancers should be avoided if possible if the required transdermal absorption rates can also be achieved without such an addition. It was indeed possible to show in DE 198 12 413 Cl that the required flow rates can also be achieved with a transdermal system without the addition of an enhancer.
- the system structures described there are geared towards hot melt technology. These enhancer-free formulations are produced on the basis of (meth) acrylate polymers containing ammonio groups.
- the hot melt process used here requires the addition of plasticizers, in this case from the group of citric acid esters. This is a severe limitation because the clear majority of TTS market products and the existing production facilities are geared towards solvent-based production and not towards hot melt technology.
- the object of the present invention was therefore to provide transdermal therapeutic systems for the administration of oxybutynin, with which therapeutically effective absorption rates can be achieved without the addition of permeation-promoting substances (enhancers) being necessary, and which are economical and economical on the basis of solvent-containing processes can be produced on a large scale and do not require the use of hot melting processes.
- the TTS according to the invention with the features mentioned in the preamble of claim 1 are characterized in that they have at least one active substance-containing matrix layer which is essentially composed of two immiscible phases (2, 3). These are an inner and an outer phase, the inner phase (2) containing the active ingredient oxybutynin base or oxybutynin hydrochloride and being dispersed in droplets in the outer phase (3).
- the outer phase is one based on coal Pressure sensitive adhesives produced from oxygen polymers and / or silicone polymers.
- a further embodiment provides that in addition to oxybutynin, the pharmacodynamically active main metabolite desethyloxybutynin is also contained in the inner phase.
- Oxybutynin and desethyloxybutynin are preferably present in a weight ratio of 1:10 to 10: 1.
- oxybutynin and, if contained in the TTS, desethyloxybutynin are at least 90% present as (S) -enantiomers.
- the active substance (s) is preferably in dissolved form, with at least 50% by weight of the active substance being dissolved, particularly preferably 90-100%.
- the matrix according to the invention By constructing the matrix according to the invention from two phases, the active substance solution or active substance-containing preparation being dispersed or emulsified in droplet form in a surrounding polymer phase, an optimal outward scavenging of the thermodynamic activity of the active substance can be achieved. As a result, it is not necessary to add enhancer substances in order to achieve adequate skin permeation rates.
- the structure of a transdermal therapeutic system is shown by way of example in FIG. 1 (sectional view).
- the active substance (s) or the active substance solution forms the inner phase (2) and is distributed in droplet form in a surrounding, pressure-sensitive adhesive outer phase (3).

- This exemplary basic type can be modified in various ways, as described below.
- the TTS can be in different geometric surface shapes are produced, e.g. B. round, oval or oblong.
- the inner phase (2) consists exclusively of the liquid active ingredient solution or dispersion. This corresponds to a droplet-like distribution of the active ingredient within an outer phase oversaturated with the active ingredient and ensures its maximum thermodynamic activity.
- the active phase-containing inner phase (2) contains an addition of one or more binders (also called thickeners). In this way it can be prevented that the active substance from the droplet-like inner phase accumulates at the interfaces or surfaces of the matrix layer, as a result of which the adhesive force of the pressure-sensitive adhesive matrix layer could be impaired.
- the drug solution emerging at the interfaces would undesirably act as a release agent, so that these layers are no longer covered with foils, e.g. B. PET films as the backing layer (1) could be laminated.
- the proportion of binder polymer in the inner phase should correspond at most to the proportion by weight of the oxybutynin contained. Too high a proportion of binder polymer in the inner phase could unnecessarily reduce the thermodynamic activity of the active ingredient due to its solubility in the binder.
- the binder or thickener is preferably present in one proportion of at least 10% by weight, preferably of 10-50% by weight, based on the inner phase.
- the inner phase of the matrix layer according to the invention which is composed of two phases, contains at least 25% by weight, preferably at least 50% by weight and particularly preferably more than 70% by weight oxybutynin, optionally in combination with desethyloxybutynin.
- binders or thickeners which have the advantages described above are polymers from the group of acrylate copolymers and methacrylate copolymers, preferably basic polymers, eg. B. (meth) acrylate copolymers containing amino groups.
- a poly (meth) acrylate copolymer of neutral methacrylic acid esters and dimethylaminoethyl methacrylate is particularly preferably used; one of these is sold under the name Eudragit E by the company Röhm Pharma.
- binders or thickeners are in particular neutral (meth) acrylate copolymers, for example a copolymer based on methacrylic acid methyl ester and methacrylic acid butyl ester (eg plastoid B; manufacturer: Röhm Pharma), or carboxyl group-free polyacrylate - pressure sensitive adhesive (e.g. Durotak 387-2516; National Starch).

- two or more of the polymers mentioned can also be present as a combination or mixture in the inner phase.
- binder polymer (s) it is important to ensure that a stable dispersion or emulsion with small droplet sizes of the inner phase containing the active ingredient is obtained in the formulation batch.
- the outer, pressure-sensitive adhesive phase (3) is preferably composed of pure hydrocarbon polymers and / or of silicone polymers.
