Definitions
- the present invention relates to a pharmaceutical composition according to the preamble of claim 1 and its use according to the preamble of claim 17.
- the hormone Altrenogest has been used for a long time to block the cycle.
- Such a cycle synchronization in fertile gilts serves the purpose of synchronizing the estrus (oestrus) and / or ovulation, so that artificial inseminations can be done at defined times waiving a laborious heat control. From such a cycle synchronization results in significant advantages for the animals and the livestock owners, namely, among other things, the elimination of seeking the brünstigen animals over several days, the ease of sperm delivery, the simultaneous entry of sows in the gestation phase and the concentration of labor input of the livestock on plannable Days and hours.
- Altrenogest products are reliable in their effect. However, from an ecotoxicological point of view, they are to be regarded as questionable.
- Levonorgestrel a structurally very similar hormone to Altrenogest, has been shown to have an adverse effect on organisms even in the smallest concentrations in the past.
- Various compositions are already known from the prior art, which allow a delayed release of an active ingredient. However, these compositions are often very complex and tailored to specific drugs.
- WO 2004/100928 A1 describes a liposome-forming depot system which is composed of specific lipids.
- WO 2005/067889 A1 describes a polymer product comprising a biodegradable polymer system which provides a delayed release of the active ingredient.
- WO 2005/1 17934 A1 describes a device for the sustained release of an active ingredient, with mannitol and dextran being used as release-delaying substances with priority.
- WO 2007/084460 A2 describes an injectable polymeric composition in which sustained release of the drug is achieved via a biodegradable polymer.
- US 4,767,628 A describes pharmaceutical compositions comprising polylactic acid, a biodegradable polymer used for the sustained release of an active ingredient.
- US 5,766,627 A describes a multi-step process for preparing multivesicular liposomes comprising several non-concentric chambers with internal membranes. These very specific liposomes can be used for the encapsulation and subsequent release of a biologically active substance.
- the present invention has for its object to provide a preparation for cycle blockade, which is effective over a defined period of time, can be easily prepared and applied and is more environmentally friendly than known from the prior art preparations.

- Suitable salts of gonadorelin or gonadorelin analogs are, in particular, water-soluble salts.
- Gonadorelin is rapidly metabolized after its release in the body of an animal. Primarily in the blood plasma, but also in various organs or tissues of the animal, hydrolysis of the gonadorelin into oligopeptides with a maximum of five amino acids takes place. These oligopeptides no longer have a biological effect, so that there is no excretion of toxic or physiologically active metabolites. Consequently, gonadorelin and gonadorelin analogs do not exert a negative environmental effect when used as veterinary pharmaceutical active substances.
- the claimed veterinary pharmaceutical composition is characterized by having a liposome-free matrix delaying the release of the veterinary pharmaceutical substance from the composition having a base material selected from the group consisting of natural and synthetic triglycerides, vegetable oils (refined or unrefined ), Diacylpropanediols, diacylbutanediols, and mixtures of these substances, wherein the veterinary pharmaceutical composition does not comprise a biodegradable polymer.
- Biodegradable polymers are, for example, those polymers which are described in WO 2005/067889 A1, WO 2007/084460 A2 and / or US Pat. No. 4,767,628.
- liposome-free is to be interpreted in such a way that a maximum of 5%, in particular a maximum of 4%, in particular a maximum of 3%, in particular a maximum of 2%, in particular maximum
- the liposome-free embodiment of the claimed veterinary pharmaceutical composition allows easy preparation of this composition. Thus, it is not necessary to mix specific aqueous and non-aqueous phases with each other in order to achieve good liposome formation. Rather, such liposomes are not required at all as structures to provide for the sustained-release veterinary pharmaceutically active substance in the matrix base materials claimed herein. If the present veterinary pharmaceutical composition contains an extremely small proportion of liposomes, these are formed by spontaneous formation do not serve to influence the drug release of the composition. Rather, it is achieved by selecting the base materials as such and not by placing them into specific microspherical structures such as liposomes.
- the veterinary pharmaceutical composition contains no acid, in particular no perchloric acid, no nitric acid, formic acid, sulfuric acid, phosphoric acid, acetic acid, glucuronic acid, citric acid, trichloroacetic acid, trifluoroacetic acid and / or salts of these acids.
- the release of the veterinary pharmaceutical substance from the composition is preferably carried out in a veterinary pharmaceutical effective dose.
- a veterinary pharmaceutical effective dose is considered to be sufficient to suppress the oestrus in the animals treated with this dose. Examples of veterinary pharmaceutically effective doses are given below.
- a veterinary pharmaceutical effective dose is higher than a veterinary pharmaceutical ineffective dose.
- a veterinarily pharmaceutically ineffective dose is in particular a dose of less than 10 micrograms per 24 hours, in particular a maximum of 9 micrograms per 24 hours, in particular a maximum of 8 micrograms per 24 hours, in particular a maximum of 7 micrograms per 24 hours, in particular a maximum of 6 micrograms per 24 hours, in particular a maximum of 5 micrograms per 24 hours, in particular a maximum of 4 micrograms per 24 hours, in particular a maximum of 3 micrograms per 24 hours, in particular maximum
- the veterinary pharmaceutical composition is a veterinary pharmaceutical substance in depot formulation.
- This depot formulation ensures that the active ingredient (ie the veterinary pharmaceutical active substance) is released from the composition at a veterinarily pharmaceutically effective dose for the desired period of time.
- the sustained action of the veterinary pharmaceutical composition requires only a single application to achieve the desired effect of the composition over the period of release. This facilitates the handling of the composition and the treatment of the animals.
- the release of the active substance in a veterinarily pharmaceutically effective dose takes place only during a period of up to 25 days, in particular up to 24 days, in particular up to 23 days, in particular up to 22 days, in particular up to 21 days, in particular up to 20 days, in particular up to 19 days, in particular up to 18 days, in particular up to 17 days, in particular up to 16 days, in particular up to 15 days, in particular up to 14 days, in particular up to 13 days, in particular up to 12 days and more particularly up to 10 days after application of the veterinary pharmaceutical composition.
- a cycle synchronization of the treated animals can be achieved in a particularly advantageous manner.
- the release of the active substance takes place in a veterinarily pharmaceutically effective dose for a period of exactly 25 days, in particular only during a period of exactly 24 days, in particular exactly 23 days, in particular exactly 22 days, in particular exactly 21 days, in particular exactly 20 Days, in particular exactly 19 days, in particular exactly 18 days, in particular exactly 17 days, in particular exactly 16 days, in particular exactly 15 days, in particular exactly 14 days, in particular exactly 13 days, in particular exactly 12 days and more particularly of exactly 10 days after application veterinary pharmaceutical composition.

- the veterinary pharmaceutical composition is provided as such a depot formulation in which the release of the active ingredient ends substantially abruptly at the end of the selected release period.
- gonadorelin by a defined and sudden drop in the release dose of the drug decreases the drug concentration in the treated organism within a short period of time from a veterinary pharmaceutical effective concentration.
- Prolonged release of gonadorelin in a veterinary pharmaceutical dose results in down regulation of the gonadorelin receptor and desensitization of the pituitary gland (and other compartments of the treated organism) to gonadorelin.
- the luteinizing hormone and the follicle-stimulating hormone which are essential for follicular development, are not released. Consequently, the follicle development is inhibited on the ovary, so that the heat of the treated organism is absent.
- the follicular growth begins again, so that a new sexual cycle can begin.
- gonadorelin [6-D-Phe] is used as the active ingredient.
- This gonadorelin analog differs from gonadorelin only in that it contains at position 6 a D-phenylalanine instead of the glycine in gonadorelin.
- the primary structure of this gonadorelin analogue is therefore as follows: pyroGlu-His-Trp-Ser-Tyr-
- Gonadorelin [6-D-Phe] has been shown to be a particularly well tolerated and effective cycle control agent in females.
- all of the above-mentioned properties of gonadorelin also apply to gonadorelin [6-D-Phe].
- gonadorelin [6-D-Phe] is used as the sole veterinary pharmaceutical substance.
- the matrix has an emulsifier. By adding such an emulsifier it can be ensured in a particularly simple and safe manner that the triglycerides, vegetable oils, diacylpropanediols and / or diacylbutanediols contained in the matrix do not form liposomes.
- a veterinary pharmaceutical composition comprising a matrix as defined above as well as an emulsifier may also be considered as a liposome-free veterinary pharmaceutical composition without the explicit addition of "liposome-free" since this implicitly results from the presence of an emulsifier.
- the present invention therefore also relates to a veterinary pharmaceutical composition
- a veterinary pharmaceutical composition comprising at least one veterinarily active substance selected from gonadorelin and gonadorelin analogs as well as salts of gonadorelin and gonadorelin analogs which composition retards release of the veterinary pharmaceutical substance from the composition Matrix and an emulsifier, wherein the matrix comprises a base material selected from the group consisting of natural and synthetic triglycerides, vegetable oils, Diacylpropandiolen, Diacylbutandiolen and mixtures of these substances, wherein the veterinary pharmaceutical composition has no biodegradable polymer.
- the emulsifier is a monoglyceride, diglyceride, partial glyceride, sorbitan fatty acid ester, fatty alcohol, lecithin, cholesterol and / or an ester of polyethylene glycol (PEG) and an oil.
- PEG polyethylene glycol
- the emulsifier is glycerol monostearate, glycerol monopalmitate, glycerol distearate, Glyceroldimyristat, Glyceroldipalmitat, glycerol monocaprylate, Glycerolstearatcitrat, glycerol stearate, Glycerolmonocaprylocaprat type I, Glycerolcocoat, glycerol, sorbitan, sorbitan monopalmitate, sorbitan monostearate, sorbitan tristearate, sorbitan monooleate, Cetylstearylalkohol , Cetyl alcohol, stearyl alcohol, myristyl alcohol, behenyl alcohol, lecithin, cholesterol, phosphatidylcholine, esterified phosphatidylcholine, (1, 2-dimyristoyl-sn-glycero-3-phosphocholine), (1-palmitoyl-2-o

- the veterinary pharmaceutical composition is a single-phase solution or dispersion of the veterinary pharmaceutical substance (ie the active ingredient) in a dispersion medium, the dispersion medium being single-phase. It is about each in particular to an oily phase.
- the word "liposome-free” can again be dispensed with in order to describe the corresponding veterinary pharmaceutical composition (compare the above formulation), since the liposome freedom implicitly results from the single-phase configuration of the composition
- the dispersion is not just an emulsion
- the dispersion medium may also be solid so that the veterinary pharmaceutical composition may be configured as a porous solid (solid foam) or a solid mixture.
- the base material is selected from the group consisting of glycerol tripalmitate, glycerol tristearate, glycerol trimyristate, glycerol tribehenate, glycerol tricaprylate, glycerol tri (caprylate / caprate), glycerol tri (caprylate / caprate / linolate), glycerol tri (caprylate / caprate / laurate) and glycerol tri ( caprylate / caprate / succinate) as well as mixtures of these substances.

- the base material is selected from the group consisting of castor oil, peanut oil, sesame oil, wheat germ oil, cottonseed oil, corn oil, palm oil, coconut oil, palm kernel oil, almond oil, olive oil, soybean oil, rapeseed oil, sunflower oil, linseed oil, poppy seed oil, rapeseed oil, grapeseed oil, jojoba oil, Evening primrose oil, mustard seed oil and mixtures of these oils.
- the base material is selected from the group consisting of propylene glycol di (caprylate / caprate) and butylene glycol di (caprylate / caprate) and mixtures of these substances.
- the active ingredient is enclosed in microcapsules or microparticles, in particular by melt dripping, which ensure the delayed release of the active ingredient from the composition over a defined release period.
- the veterinary pharmaceutical composition is in such a formulation, the release of the active ingredient in a dose of 10 to 1000 micrograms per 24 hours, in particular 20 to 900 micrograms per 24 hours, in particular 25 to 800 micrograms per 24 hours, in particular 30 to 700 micrograms per 24 hours, in particular 40 to 600 micrograms per 24 hours, in particular 50 to 500 micrograms per 24 hours, in particular 60 to 400 micrograms per 24 hours, in particular 70 to 300 micrograms per 24 hours, in particular 80 to 200 micrograms per Guaranteed 24 hours and especially 90 to 100 micrograms per 24 hours.
- this dose is a veterinary pharmaceutical effective dose.
- the release of the veterinary pharmaceutical substance takes place shortly (for example a few hours to 1 day, 2 days, 3 days or 4 days) after administration in a larger dose than at a later time (for example 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 1 1 day, 12 days, 13 days, 14 days, 15 days, 16 days, 17 days, 18 days, 19 days, 20 days, 21 Days, 22 days, 23 days, 24 days or 25 days after application).
- This effect is also called flooding.
- the veterinary pharmaceutical composition is provided as a dimensionally stable formulation.
- dimensionally stable formulations such as microcapsules or microparticles, are particularly suitable as implants, which then release a drug during the release period.
- implants can also be injected by means of a suitable injector, in particular a standard syringe.
- Dimensionally stable formulations maintain their dimensional stability over the matrix, which serves as carrier material for the active ingredient.
- the veterinary pharmaceutical composition contains at least one additive.
- This additive may be a porosity agent, a lipid, a phospholipid, a thickener and / or a partial glyceride.
- Porosizing agents are understood as meaning those agents which serve to produce pores in another substance.
- pores in a matrix can be produced by suitable pore-forming agents when the veterinary pharmaceutical composition is in the form of a stable formulation.
- Suitable porosity agents are, for example, polyethylene glycol or a sugar such as glucose, fructose or sucrose. Also mixtures of different porosity agents are conceivable.
- Substances with a low melting point ie a melting point which is equal to or less than 50 ° C., in particular equal to or less than 45 ° C., in particular equal to or less than 40 ° C., but greater, are substances which are particularly suitable as base material of the matrix for dimensionally stable formulations than the body temperature of the organism to be treated. In pigs the body temperature is 38.8 ⁇ 0.3 ° C.
- the galenics of the veterinary pharmaceutical composition are selected such that the composition is present as a non-stable formulation, for example as a suspension or as a gel. Oily suspensions are particularly preferred.
- the veterinary pharmaceutical composition is present as an emulsion. Gels, suspensions and emulsions are easily administered by injection to an organism to be treated. As explained above, a single application of the veterinary pharmaceutical composition is sufficient in order to achieve an effect of the active substance over the release period.
- Substances with a melting point lower than the body temperature of the organism to be treated are substances which are particularly suitable as base material for the matrix for non-stable formulations 30 ' ⁇ , in particular less than or equal to 25 ° C and very particularly less than or equal to 20' ⁇ .
- the substances such as vegetable oils, do not have a precisely defined melting point, but have a melting range
- the upper limit of the melting range is to be equated with the melting point according to the above definitions.
- Thickening agents can be used to adjust the viscosity of a non-rigid formulation of the veterinary pharmaceutical composition. Furthermore, the strength of the matrix can be influenced in this way if the veterinary pharmaceutical composition is in the form of a stable formulation.
- Phospholipids and partial glycerides are regularly water-dispersible and in this way can likewise influence the viscosity of the suspension or strength of the matrix. All of these additives can thus be used to influence drug release from the veterinary pharmaceutical composition.
- the active ingredient can be released much more easily from a matrix with a high porosity, which already starts to melt at body temperature of the animals in which the veterinary pharmaceutical composition is to be used, than from a matrix with low porosity, even at higher temperatures.
- the particle size of the drug Another factor that is crucial for drug release and stability of the veterinary pharmaceutical composition is the particle size of the drug.
- the active ingredient is ground regularly before it is incorporated into the veterinary pharmaceutical composition.
- different sized drug particles that allow different levels of release of the drug.
- the lipids provided as adjuvants or additives can be introduced into the veterinary pharmaceutical composition in the form of microparticles, as can the active ingredient itself.
- the mode of action of such auxiliaries or additives in the form of microparticles is different than when these substances are present in larger particles.
- a thickener as an additive when the veterinary pharmaceutical composition is present as a non-stable formulation (for example as a suspension).
- a phospholipid as an additive when the veterinary pharmaceutical composition is present as a non-stable formulation.
- a porosifying agent is provided in particular when the veterinary pharmaceutical composition is in the form of a stable formulation. Furthermore, the use of lipid microparticles is also particularly provided when working with a dimensionally stable formulation of the veterinary pharmaceutical composition.
- Another variant for influencing the release of active ingredient from the veterinary pharmaceutical composition is to change the matrix of a dimensionally stable formulation itself. This can be done for example by a change in the concentration of the matrix substance or by different matrix substances. In this variant is it is not necessary to add further additives to the matrix. In principle, however, it is also possible to change the matrix itself and to add additives.
- the invention also relates, in a variant, to a veterinary pharmaceutical composition containing at least one veterinarily active substance, namely gonadorelin and / or a gonadorelin analogue or more gonadorelin analogues and / or one or more salts of gonadorelin and / or gonadorelin analogue or gonadorelin analogs, wherein the composition contains at least one adjuvant that specifically retards release of the veterinary pharmaceutical substance from the composition.
- the excipient interacts with the pharmaceutically active substance such that the release of the veterinary pharmaceutical active substance in a veterinarily pharmaceutically effective dose occurs only for a period of up to 18 days after application of the veterinary pharmaceutical composition.
- the excipient is a glyceride such as a natural triglyceride, a synthetic triglyceride or a partial glyceride, a fatty acid, a fatty acid salt, a fatty acid ester, a lecithin, a polyester, a polyanhydride, a polysaccharide, a semisynthetic polysaccharide derivative, a polyacrylate, a polyethylene glycol, a polypropylene glycol, a polyester and / or an N-methylpyrrolidone.
- Suitable fatty acid salts are, for example, a stearate and / or a palmitate.
- Suitable fatty acid esters are, for example, fatty acid esters with long-chain alcohols (containing more than 8 carbon atoms), such as waxes or fatty acid esters with short-chain alcohols (containing 8 and fewer carbon atoms, especially 2 or 3 carbon atoms), such as esters or partial esters with glycerol or propylene glycol.
- Suitable polysaccharides are, for example, hyaluronic acid or hydroxyethyl cellulose.
- Suitable polyesters are, for example, lactic acid polymers or lactic acid copolymers.
- the excipient composition causes a delayed release of the active ingredient from the veterinary pharmaceutical composition, so that sets their depot effect in a particularly advantageous manner.
- the excipient is aluminum stearate and / or dextrin palmitate.
- the excipient is polylactic polyglycolic acid. Also, this lactic acid copolymer has been found to be particularly advantageous for achieving the desired depot effect.
- the dimensionally stable formulation has a glyceride as matrix or adjuvant.
- Natural or synthetic triglycerides are particularly suitable for this purpose.
- monoglycerides or diglycerides (partial glycerides) have also proved to be suitable matrices or auxiliaries for dimensionally stable formulations of the veterinary pharmaceutical composition.
- the present invention also relates to the use of a veterinary pharmaceutical composition as described above in the cycle control of (female) animals.
- the veterinary pharmaceutical composition can be used in particular for cycle blockage and cycle synchronization of (female) animals.
- the animals are preferably mammals, in particular rodents or cloven-hoofed animals.
- the term "animal" does not include the term "human”.
- a parenteral, in particular intravenous, administration of the veterinary pharmaceutical composition is provided.
- gonadorelin or a gonadorelin analog over a prolonged period inhibits the secretion of the luteinizing hormone and the follicle-stimulating hormone.
- follicular development on the ovary of the treated animal is inhibited.
- follicular growth resumes, allowing a new sexual cycle to begin.
- the veterinary pharmaceutical composition described herein can be used as veterinary drugs for cycle synchronization known in the art.
- the veterinary pharmaceutical composition described herein has advantageous environmental properties, as explained above. It also only has one Times to achieve a cycle synchronization of individual animals in a group.
- the veterinary pharmaceutical composition is used for cycle control of gilts. Due to the relatively high number of pigs that are kept together in a stable or in a group, cycle synchronization of gilts offers particularly many advantages of the described veterinary pharmaceutical composition. In principle, however, it can also be used in other animals, such as mares or bitches.
- the novel veterinary pharmaceutical composition described herein has the same uses as the veterinary drugs already known in the art, but which are not endowed with the beneficial environmental properties of the present composition.
- the presently claimed veterinary pharmaceutical composition must be applied only once in order to develop their beneficial properties. This significantly reduces the amount of work involved in using and the stress associated with the animals being treated.

- Figure 1 shows four in vitro release kinetics of gonadorelin [6-D-Phe] acetate in different oily suspensions. The release is delayed in each case with respect to a non-release retarding matrix.
- the castor oil was mixed with the Miglyol in the ratio 9: 1 at 60 ° C under nitrogen. The mixture was then cooled to 25 ° C and lyophilized gonadorelin [6-D-Phe] acetate added. It was followed by a 5-minute homogenization with an Ultra-Turrax at 2000 rpm. Subsequently, the solution was diluted with castor oil and / or miglyol in order to achieve the gonadorelin [6-D-Phe] acetate concentrations and viscosities mentioned in the table above.
- the release kinetics shown in FIGS. 2 to 10 relate to the release of gonadorelin [6-D-Phe] as active ingredient from dimensionally stable matrices obtained according to the following experimental setup: 50 mg of particles (comprising matrix and active substance) were introduced into a dialysis tube with a Cut-off of 12000-14000 given and dispersed in 2 ml of phosphate buffered saline buffer (PBS buffer). Gonadorelin-6-D [Phe] has a molecular weight of about 1000 Da and was able to pass through the dialysis membrane unhindered. The dialysis tubing was sealed and placed in a tube with another 15 ml PBS buffer. The subsequent dialysis was carried out at 39.degree. From the dialysate samples of 1 ml were drawn at defined times and the volume removed was replaced with fresh buffer. In the drawn samples, the amount of gonadorelin [6-D-Phe] released from the particles was determined.
- PBS buffer phosphate buffere
- FIG. 11 shows the release kinetics of a comparative example in which the matrix does not consist of one of the claimed substances but only of one monoglyceride, namely glycerol monostearate. Release kinetics were obtained in the same manner as the release kinetics shown in Figs. 2-10.
