Definitions
- the present invention relates to new carrier systems for the transport of active substances through nails and skin in the topical treatment of nail diseases and periungual diseases.
- Treating nail diseases is difficult, although a variety of active ingredients are available. Both systemic and, in particular, topical therapy require a long treatment period. The prospects for a successful treatment of the nail disease are greater with the systemic treatment. However, there are often intolerances and side effects, such as: B. Hepatotoxicity, gastrointestinal disorders, nausea, prutus and others (Martindale, 29 Ed., 416-35; Goodman and Gilman's, 8 Ed., 1165-1181).
- the topical treatment of nail diseases is practically free of side effects, but the healing success is low compared to systemic treatment, since the active substance can penetrate the nail in part, but does not get deep enough into the nail bed and the nail root, where the disease-forming germs can be found are located. In this way, the symptoms of the disease subside after about 6 months, but they appear again after the treatment is stopped, since the active substance has not penetrated into the nail bed and the nail root, where the germs develop. (Clinical and Experimental Dermatology, 1992, 17, Suppl. 1, 26-28).
- the affected nail can also be treated with a keratinolytic agent, e.g. Urea, removed and then treated with an appropriate active ingredient.
- a keratinolytic agent e.g. Urea
- Urea e.g. a keratinolytic agent
- a long treatment time (10 - 40 days until the affected nail material has been removed and up to 49 days of local treatment) and a healing rate of around 85% must be expected (Dt. Derm., 1988, 36,8, 846- 849).
- EP-B-64'830 it is proposed to penetrate the active substance by adding a long-chain fatty acid, e.g. To promote 10-undecenoic acid.
- a long-chain fatty acid e.g. to promote 10-undecenoic acid.
- the sole use of an unsaturated fatty acid cannot satisfactorily ensure that the active substance is penetrated by the nail.
- US Pat. No. 5,519,059 describes an antifungal formulation which contains a mixture of isopropanol, propylene glycol, isopropyl myristate or polyethylene glycol as carrier and tolnaftate as active substance.
- the present invention relates to a carrier system for the penetration of active substances through nail and skin, comprising a) an unsaturated branched or unbranched fatty acid with 5 to 15 carbon atoms, b) a branched or unbranched alcohol with 1 to 3 hydroxyl groups and 2 to 6 Carbon atoms, where the hydroxyl groups can be partially or completely etherified, and c) an ester of a saturated or unsaturated, branched or unbranched fatty acid with 8 to 21 carbon atoms, wherein the alcohol components in the ester can be branched or unbranched alcohols with 1 to 6 carbon atoms .
- Component a) of the Carner system includes the group of unsaturated branched or unbranched fatty acids with 5 to 15 carbon atoms.
- the carrier system according to the invention preferably contains unbranched unsaturated fatty acids. Suitable unsaturated fatty acids are, for example
- Unsaturated fatty acids with a terminal double bond are preferred. Among these, those with 8 to 12 carbon atoms are preferred. Individual representatives of such preferred unsaturated fatty acids are
- a particularly preferred unsaturated fatty acid is 10-undecenoic acid Component b) of the new carrier system contains compounds which are composed of a branched or unbranched alcohol having 1 to 3 hydroxyl groups and 2 to 6 carbon atoms, it being possible for the hydroxyl groups to be partially or completely etherified. Unbranched and branched alcohols having 2 to 4 carbon atoms and 1 to 3 hydroxyl groups are preferred. Suitable alcohols of this type are, for example:
- Preferred alcohols are:
- Particularly preferred alcohols are:
- Component c) of the new carrier system contains esters of a saturated or unsaturated, branched or unbranched fatty acid with 8 to 21 Carbon atoms, wherein the saturated fatty acids preferably contain 12 to 14 carbon atoms and particularly preferably 14 carbon atoms and the unsaturated fatty acids preferably contain 12 to 21 carbon atoms and particularly preferably 18 to 21 carbon atoms.
- Suitable alcohol components of these fatty acid esters are branched or unbranched alcohols having 1 to 6 carbon atoms and 1 to 3 hydroxyl groups. Particularly suitable alcohols are: methanol, ethanol, n-propanol, isopropanol, n-butanol, se ⁇ -butanol, isobutanol, methoxyethanol and glycerin.
- Suitable fatty acid esters which can be contained in the carrier system according to the invention as component c) are, for example:
- Preferred fatty acid esters which may be present as component c) in the carrier system according to the invention are: isopropyl tridecanecarboxylate
- 9-octadecenoic acid glycerol monoester glycerol monooleate
- a particularly preferred ester of a saturated fatty acid, which may be present as component c) in the carrier system according to the invention, is isopropyl tetradecanecarboxylate (isopropyl myristate).
- a particularly preferred ester of an unsaturated fatty acid which is present as component c) in the carrier system according to the invention can be is 9-octadecenoic acid glycine monoester (glycerol monooleate)
- the present carrier systems according to the invention have the advantage that they penetrate the diseased nail together with the active substance within about 3 to 8 days and can develop their effect at the actual infection site in the nail bed and on the nail root.
- the pathogens are completely killed off and after the treatment the patient remains symptom-free Due to the quicker onset of action and the better penetration, the treatment is usually completed after about two to three months.
- This method significantly improves patient compliance, since the usually long treatment period of 6 months and longer is significantly shortened In the case of diseased skin, in particular in the case of pe ⁇ ungual skin areas, the healing process occurs more quickly, since the active ingredient penetrates the skin efficiently and quickly
- test solution penetrated the nail stucco after 3 days in all five samples.
- the beeswax under the nail sticks is discolored in yellow.
- the thin layer chromatogram shows that the active ingredient has actually penetrated the beeswax
- the test arrangement corresponds to that of penetration test A.
- the pig's hooves are brushed with the following tincture, which has been colored yellow with a little picric acid
- the present invention furthermore relates to medicaments for the topical treatment of nail and penile diseases which contain the carrier system according to the invention, an active substance or a combination of active substances and, if necessary, therapeutically inert excipients
- Suitable active ingredients are, for example, the following antifungals and their physiologically acceptable salts
- Suitable active ingredients are, for example, the following antibiotics and their physiologically acceptable salts
- Suitable active ingredients are, for example, the following antiseptics - alkylbenzyldimethylammonium chloride (benzalkonium chloride)
- Suitable active ingredients are, for example, the following corticosteroids and their physiologically acceptable salts - 9-Chloro-16ß-methylpredn ⁇ solon (beclomethasone)
- corticosteroids and their physiologically acceptable salts are preferred - 11 ß, 16 ⁇ , 17 ⁇ , 21-tetrahydroxy-1, 4-pregnad ⁇ en-3.20-d ⁇ on-16, 17-acetonacetal (desonide)
- Combinations of active ingredients of corticosteroids with antifungals, antibiotics or antiseptics are also suitable.
- a preferred example of this is
- the carrier systems according to the invention can be processed in all galenic forms customary for the indicated indication group.
- Such pharmaceutical dosage forms are mainly topically administrable preparations such as tinctures, emulsions, solutions, ointments, creams, gels and pastes
- the pharmaceutical preparations listed generally contain a proportion of carrier system of at least 10% up to a maximum of 99.9%. A proportion of carrier system of 50% to 99.5% is preferred and preparations with 85% to 99% are particularly preferred. on carrier system
- the mixing ratio of the components of the carrier system can be varied. However, it should preferably contain at least 30% to 33% of an unsaturated branched or unbranched fatty acid with 5 to 15 carbon atoms (component a).
- component a unsaturated branched or unbranched fatty acid with 5 to 15 carbon atoms
