Definitions
- the invention relates to a process for the production of active substance-containing bone cements, as well as bone substitute materials or implantable pharmaceutical depots that can be produced therefrom.
- Bone cements, bone replacement materials and implantable pharmaceutical depots based on acrylic plastics have been known for a long time.
- Polymer materials based on acrylic and / or methacrylic acid esters have proven themselves here because of their biocompatibility, their excellent strength properties, their favorable properties when releasing stored pharmaceutical active ingredients and, last but not least, because of their processability which is suitable for the application.
- Common bone cements consist of about 50 to 75% by weight of a solid component consisting of a finely divided polymer of acrylic and / or methacrylic acid esters and optionally other additives such as polymerization catalysts, X-ray contrast agents, fillers and dyes, and about 25 to 50% by weight.
- % of a liquid component which consists of an acrylic and / or methacrylic acid ester monomer, and optionally further additives such as polymerization accelerators and stabilizers.
- the solid component and the liquid component are mixed into a liquid to semi-solid paste, if necessary brought into a desired shape or applied to cement a prosthesis at the implantation site.
- the mass is cured by the polymerization reaction induced by the mixing of the components.
- a bone cement is very common, for example, which contains 2 bags in a normal pack, each with about 40 g of polymer powder and 2 ampoules, each with 20 ml of monomer liquid.
- the powder is a fine polymer made from methacrylic acid methyl ester with a copolymer portion of acrylic acid methyl ester. About 0.5% dibenzoyl peroxide is added to the powder as a catalyst. To identify the material, small amounts of chlorophyll are co-polymerized during manufacture.
- the powder contains in addition a conventional X-ray contrast medium such as zirconium oxide.
- the associated liquid consists of monomeric methyl methacrylate, to which about 0.7% dimethyl-p-toluidine is added as a polymerization accelerator and small amounts of hydroquinone are added as a stabilizer. This liquid is also usually colored with a small amount of chlorophyll for labeling.
- the powder packed in polyethylene bags is sterilized with ethylene oxide. The liquid is sterile filtered and filled into glass ampoules.
- the dibenzoyl peroxide reacts with the dimethyl-p-toluidine in the liquid, which stimulates the radical polymerization.
- the mixture is adjusted so that it can be used as a doughy paste after about a minute. This paste remains kneadable for several minutes and then begins to harden with the development of heat.
- the polymerization is essentially complete after about 5 to 10 minutes. During the polymerization phase, as long as the paste is still moldable, it can be brought into any desired shape, for example, to fill bone cavities or to cement prostheses directly into the body or to produce
- Shaped bodies are used, which harden extracorporeally and can then be used on any part of the body.
- Bone cements containing cytostatics can be used to repair bone defects after removing bone tumors.
- bone cements that contain antibiotics, antiseptics and, if necessary, substances that promote bone growth are advantageous.
- Shaped bodies made of active substance-containing bone cements can be implanted in soft tissue as local active substance depots with delayed active substance release.
- Commercially available bone cements with added antibiotics eg Septopal ®
- other antibiotics are added to such cements to increase their effectiveness.
- EP 0 202 445 A1 describes such a cytostatic-containing bone cement and a pharmaceutical deposit made therefrom with particularly favorable release properties.
- This publication shows that the respective active ingredient is admixed to the base material of the bone cement, that is to say the prepolymer and / or the monomer as a finely divided powder, so that it is then homogeneously distributed in the resulting polymer.
- EP 0 701 824 A2 describes a process for the preparation of bone cements containing active substance, the active substance being dissolved in an organic solvent and this solution being mixed with the liquid component or with the solid component. In this way, all three components of the bone cement can be made available in sterile form.
- the pre-assembled bone cement components which are primarily optimized for their mechanical properties or in a simple manner for the sterilization of the components, do not, however, meet the requirements that must be placed on a medical product intended for implantation in the body , since they have only suboptimal properties for use as active substance carriers.
- release-promoting substances as a powder to the cement (eg salt, sugar, amino acids) has the disadvantage that a homogeneous and reproducible mixture is practically impossible to achieve.
- An inhomogeneous mixture necessarily requires large amounts of active ingredients and auxiliary substances in order to achieve the desired releases.
- active substance-containing bone cements the release usually remains well below therapeutically desirable levels. This is especially true for implants with unfavorable geometrical conditions (e.g. cement seals).
- the invention thus relates to a process for the production of a bone cement, bone substitute material or corresponding implantable pharmaceutical deposit based on acrylic and / or methacrylic acid ester polymers containing one or more active ingredients by mixing one
- solid component (i) consisting essentially of polymeric acrylic and / or methacrylic acid ester in a proportion of 50 to 75% by weight, based on the bone cement, and one or more active pharmaceutical ingredients with a
- liquid component (ii) consisting essentially of monomeric acrylic and / or methacrylic acid ester in a proportion of 25 to 50% by weight
- liquid component (ii) with an organic solvent.
- Bone cements of this type are commercially available. The skilled worker is familiar with their composition and the way in which they are processed.
- an active substance-containing bone cement it is provided according to the invention to dissolve the monomer component in an organic solvent and then to mix this monomer solution with the finely divided polymeric solid component of the bone cement which contains the active substance.
- the solvent is not involved in the reaction or participates as a polymerization partner, as in the case of vinyl pyrrolidone.
- the monomer solution is previously sterile filtered, the solid component is subjected to a final sterilization by means of radiation and / or ethylene oxide.
- Preferred solvents are e.g. 2-pyrrolidone, N-methylpyrrolidone, dimethyl sulfoxide (DMSO), tetrahydrofuran (THF), dioxane, ethylene glycol, propanediol, vinyl pyrrolidone or mixtures of the solvents mentioned.
- Such solvents are expediently selected in which the monomer provided dissolves well.
- the amount of solvent is chosen so that it does not exceed 50% by weight, based on the liquid monomer. This ensures that the processing properties, the hardening characteristics and the mechanical strength of the hardened bone cement do not change too much when the components are mixed to form the ready-to-use bone cement.
- An amount of solvent is preferably selected such that its proportion is 1 to 25% by weight, in particular 5 to 20% by weight, based on the liquid monomer component.
- the amount of pharmaceutical active ingredient used, which is admixed with the bone cement depends on its specific effectiveness, the medical indication and on the particular requirement profile of the bone cement or the one to be produced therefrom
- Bone substitute or pharmaceutical depots As a rule, a proportion of active pharmaceutical ingredient of 0.1 to 5% by weight, based on the total amount of bone cement, is sufficient; in individual cases, in particular in the manufacture of implantable pharmaceutical depots, the active ingredient content can also be higher, for example up to 40% by weight.
- the active substances are preferably cytostatics such as methotrexate, cisplatin, cyclophosphamide, fluorouracil, doxorubicin etc., antibiotics such as vancomycin, netilmicin, gentamicin, clindamycin, vancomycin, teicoplanin etc., furthermore antiseptics and substances which promote bone growth.

- the release behavior of the active ingredient can be influenced and, if necessary, further improved by the known and customary additives.
- Amino acids such as arginine and hydroxylapatite or sodium hydrogen carbonate are possible as such additives, preferably in finely divided form with particle sizes below 100 ⁇ m.
- Such additives can be used in particular to regulate the initial concentration of the active ingredient release.
- the solid component which is usually present as a copolymer of methyl methacrylate-methyl acrylate copolymer with particle sizes between 5 and 250 ⁇ m, contains a polymerization catalyst such as dibenzoyl peroxide and the pharmaceutical ingredient. It can also use X-ray contrast media such as zirconium dioxide, dyes to identify Drawing such as chlorophyll and fillers and possibly contain other additives. Common fillers are, for example, osteoinductive or osteoconductive calcium phosphates such as, in particular, hydroxylapatite and tricalcium phosphate. The proportion of all these additives can vary within a wide range and depends on the particular one
- the liquid monomer component methyl methacrylate generally contains a polymerization accelerator such as dimethyl p-toluidine and hydroquinone as a stabilizer in the amounts customary for this. Dyes and other useful additives may also be present.
- the solid component can easily be sterilized with ⁇ -radiation or with ethylene oxide; the liquid component can be subjected to sterile filtration. Both components can be separated and filled sterile into appropriate containers.
- the active substance-containing bone cement is expediently provided in the form of a set which is composed of separate packs of the two main components.
- Component (a) contains the solid component, consisting of a finely divided polymer of acrylic and / or methacrylic acid esters, a pharmaceutical active ingredient, and optionally further additives such as polymerization catalysts, X-ray contrast agents, fillers and dyes, the proportion of which is about 50 to 75% by weight of the Bone cement is.
- Component (b) contains the liquid component, consisting of an acrylic and / or methacrylic acid monomer and optionally further additives such as polymerization accelerators, stabilizers and release-promoting substances, the proportion of which is about 25 to 50% by weight of the bone cement, in an organic solvent, the proportion of which does not exceed 50% by weight, based on the liquid component,
- the amounts of the components are preferably matched to one another such that the entire two pack contents are combined with one another.
- the quantity is adjusted according to the intended application and depending on whether a low-viscosity, a medium-viscosity or a high-viscosity cement is desired.
- the celebration- The material component has been subjected to a final sterilization by means of radiation or ethylene oxide, the liquid monomer solution has been subjected to sterile filtration and has been filled into suitable packaging in a sterile manner.
- Bone cement Mix and / or apply the bone cement.
- Appropriate devices are known and used.
- Corresponding devices preferably enable the bone cement to be mixed under vacuum and the cement to be applied in combination by means of a bone cement syringe.
- the production of the ready-to-use active ingredient-containing bone cement and its further processing take place in a completely analogous manner to previous bone cement systems.
- the active ingredient-containing bone cement can be used in the usual way during the liquid or plastic stage for the implantation of bone prostheses.
- the surgeon can also process the mass into shaped bodies of any shape and size and, after hardening, implant them as local active substance depots in the areas of the body to be treated.
