Definitions
- the present invention relates to a new tar-containing composition, a cosmetic preparation containing the same, its use, and pharmaceutical preparations containing the composition according to the invention.
- Tars are mixtures with different chemical constituents and consist primarily of hydrocarbon mixtures with a high proportion of aromatic hydrocarbons with antiproliferative properties. Their therapeutic usability, especially in dermatological indications, has been known for decades. Topically applied, tars have an anti-inflammatory, antipruritic and weakly infectious effect. They have long been successful in the treatment of flaky and chronic skin diseases that are associated with more or less severe itching, e.g. Neurodermatitis, psoriasis, chronic eczema, etc., used. Coal tar distillates (Pix lithantracis) are most commonly used, either undiluted in the form of tar envelopes or as a component of ointments and pastes
- Balneum Hermal 10 with tar as part of balneotherapy use up to 30% coal tar distillate. In comparison, the tar concentration in dermatics is considerably lower at 2% by weight.
- the object of the present invention is therefore to find a way by which the absolute dose of the applied tar derivatives can be reduced without reducing the positive therapeutic effects.
- composition comprising the following components:
- nanodisperse systems can be formed which, when applied locally, topically penetrate the skin much better than conventional carrier systems and are distributed much more quickly and homogeneously in the cornea and epidermis.
- concentration of the active ingredient mixture can be reduced to 0.1 to 0.01% of conventional tar-containing preparations.
- the tar concentration of preparations which have been produced with the compositions according to the invention is therefore a factor of 20 to 200 lower than in currently approved dermatics.
- nanodisperse carrier systems such as, for example, nanoemulsions or liposomes, there are generally fewer side effects of drugs.
- the phospholipid contained in the composition according to the invention is preferably a phosphatidylcholine of pharmaceutical quality, the aliphatic residues of the phospholipid preferably comprising 12 to 22 carbon atoms with up to 4 cis double bonds. Unbranched aliphatic radicals are preferred. A phospholipid in which the aliphatic radicals have 16 to 20 carbon atoms and a maximum of 3 cis double bonds, as in natural vegetable lecithins, for example soybean lecithin, is particularly preferred.
- the aliphatic radicals R 1 and R 2 can have the same or different number of carbon atoms. According to the invention, the phospholipid can be natural, semi-synthetic or fully synthetic.
- the bile acid and / or its derivatives can also be of natural, semi-synthetic or fully synthetic origin.
- Preferred derivatives are bile acid salts, especially sodium salts.
- the composition according to the invention comprises one or more sodium salts from the group consisting of sodium cholate, sodium deoxycholate, sodium glycocholate, sodium taurocholate, sodium taurodeoxycholate, sodium tauroursocholate and sodium chenoxycholate and / or one or more of the corresponding bile acids.
- the tar derivative is preferably a coal tar derivative.
- coal tar distillate is used in the composition.
- ethanol 96% ethanol according to DAB10 is preferably used as ethanol.
- Ethanol imparts long-term stability to the finely dispersed system formed with the composition according to the invention and also appears to enhance the effect of the therapeutically active tar derivative.
- the water used should be of the quality required for pharmaceutical or cosmetic products.
- the composition according to the invention is preferably provided as a concentrate in which the phospholipid is contained in a concentration of 10 to 200 mg / ml, preferably 40 to 100 mg / ml, and the bile acid and / or its derivative (s) ) is (are) in a molar ratio of 2 to 10 to 1 (lipid to cholate).
- Ethanol is preferably in a ratio of between 1: 2 and 1: 0.5 (v / w, ie volume / weight), based on the phospholipid, particularly preferably in a ratio of 1: 1.
- the concentrate according to the invention is diluted for use in a ratio of 1: 1 to 1: 200, preferably 1: 5 to 1: 125 and particularly preferably 1:20 to 1: 100.
- Water or salt solutions serve as diluents, preferably those with 0.1 to 0.9% by weight of common salt.
- composition is preferably used as a finely dispersed system based on lipid mixtures, micelles, mixed micelles, reverse micelles, uni-, oligo- or multilamelar liposomes, nanoemulsions, nanoparticles or nanocolloids.
- Finely disperse systems are understood here to mean systems with particles whose diameter is approximately 4 to 500 nm. The average diameter of the particles is preferably less than 250 nm.
- one or more pharmaceutical and / or cosmetic auxiliaries can be added to the composition.
- one or more unsaturated phosphatidylcholines are used as the phospholipid, it is advisable to add antioxidants to the composition.
- tocopherol is used as an antioxidant.
- salts in particular table salt or buffer substances, can also be added.
- auxiliaries such as cosurfactants, for example polysorbate or free fatty acids, usually contained in medicinal products and / or cosmetics can be acids, as well as thickening agents and also preservatives.
- composition according to the invention is particularly suitable for producing a cosmetic preparation. Additional cosmetic additives and perfuming agents can be added to this.
- composition according to the invention serves as the basis of a pharmaceutical preparation.
- a pharmaceutical preparation typically contains
- the pharmaceutical preparation according to the invention is particularly suitable for the therapy of flaking and chronic skin diseases.
- diseases are psoriasis, in particular psoriasis guttata, psoriasis en plaques, psoriasis inversa, psoriasis erythrodermica, psoriasis pustulosa, in particular psoriasis pustulosa palmaris et plantari ⁇ , psoriasis on the hairy head and psoriasis on the nails.
- the pharmaceutical preparation according to the invention can also be used for the therapy of neurodermatitis, for the therapy of allergic contact eczema and for the therapy of seborrhoeic eczema. Its effectiveness has also been shown to be useful in the therapy of Lying Simplex Chronicus (Lying Vidal, Neurodermatitis circumscripta), the eczema cornea and the keratodermica rykteria Hatchausen.
- the preparation according to the invention is thin-liquid and can be sprayed onto diseased areas using commercially available atomizers. This makes it very easy and convenient to use both on the skin and on the hairy head.
- the preparation can be applied very quickly and evenly to the entire surface of the diseased area. It penetrates quickly into the cornea. A tedious washing off as with the conventional tar-containing ointments, e.g. Linola
- Fett N ® is omitted because excess hair can be easily rinsed out with water.
- the preparation produces neither itching nor burning and is well tolerated. It is low in odor and does not stain the skin or clothing. So far it has been well received by all patients.
- the finely dispersed systems according to the invention in the form of pharmaceutical or cosmetic preparations according to the invention can be produced from the composition according to the invention described above by adding mechanical energy, for example by optimized mixing in a static mixer, pressure filtration, stirring, homogenization or filtration.
- Commercially available devices can be used for this, such as, for example, static mixing systems or homogenizers from Gaulin or a microfluidizer. If more than 100 mg / ml of oil, based on the composition, is added in these processes, the process leads to nanoemulsions or nanocolloids, and without the addition of oils or an oil concentration of ⁇ 30 mg / ml, based on the composition, leads to liposomes.
- Examples 1 to 3 show three different basic formulations for preparations according to the invention.
- Example 4 the results of the use of pharmaceutical preparations according to the invention are reported.
- Example 3 The two solutions from Example 1 are combined and homogenized with a household mixer, eg SG rod. The resulting finely dispersed system is brought to the desired application concentration by dilution with water. Depending on the requirements, sterile filtration is carried out or not.
- a household mixer eg SG rod.
- the resulting finely dispersed system is brought to the desired application concentration by dilution with water. Depending on the requirements, sterile filtration is carried out or not.
- Example 1 500 g of lecithin as in Example 1 are dissolved in 500 ml of 96% ethanol together with 100 g of tar distillate. 15 g of cooking salt and 80 g of sodium cholate are dissolved in 4 kg of water. Both solutions are combined and in a standard agitator, e.g. Staphan UMC 12, stirred. The resulting finely dispersed system is brought to the desired final concentration by dilution with water. If necessary, a sterile filtration is connected.
- a standard agitator e.g. Staphan UMC 12
- the preparation according to the invention has a good to very good effect in the treatment of the diseases described.
