Definitions
- the invention relates to an implantable drug depot for therapeutically active substances. Areas of application are medicine and the pharmaceutical industry.
- EP 126 751 describes preparations which contain a mixture of a biologically active material and one or more amphiphilic substances, these substances, together with liquids, having to be capable of forming a liquid crystalline phase.
- the most important amphiphilic substance is monoolein, with the thermotropic and lyotropic mesophases with water in the foreground.
- the aim of the preparations is to achieve the slow and even release of the biologically active material (e.g. benzylpenicillin, insulin) at the site of action and to protect it from interfering interactions with the organism.
- the biologically active material e.g. benzylpenicillin, insulin
- the aim of the invention is the use of the gel-like cubic mesophases of the monoolein-water system as an implantable drug depot for the treatment of tumors in cancer therapy and in gene therapy.
- a rational membrane design is to be developed in order to be able to control the release of the active substances in terms of the period and the amount.
- a major advantage of this invention is that the drug depot is completely biodegradable. It can be applied to exposed tissue (e.g. after surgery) and surprisingly adheres very well to mucous membranes. This enables effective local treatment of tumors and the removal of restenotic areas.
- Another advantage is that the release of the pharmaceutically active substances can be controlled depending on the choice of the modifier in terms of the period and the amount.
- the release of the active ingredient can be achieved.
- the release can be fine-tuned. For example, with a length of the polyethylene chain of 500 units, the active ingredient is released over 4 days. If the polyethylene chain has a length of 2000 units, delivery of the active ingredient is extended to over 7 days.
- a local after surgical removal of the main tumor mass, in the form of the gels brought in mono- or polychemotherapy (carboplatin. And taxol) improves the prospects of a lifetime extension while maintaining the quality of life.
- the active substance depot according to the invention can be used as a double-release system for cytostatics for direct (local) chemotherapy.
- the release kinetics were measured on cubic lipid systems and drug depots that can be implanted from them.
- the cubic phases exist in excess water and are therefore relatively stable against contact with body fluids such as blood or lymph fluid.
- body fluids such as blood or lymph fluid.
- the high viscosity makes it very easy to handle and the systems have good adhesion to mucous membranes and other biological tissue, e.g. B. Coating of networks.
- the system of three-dimensional water channels in the interior of the cubic phases means that a water-soluble substance such as carboplatin is incorporated in the water channels. It is protected against direct contact with body fluids and thus against attacks by macrophages or enzymes and can thus diffuse out of the depot relatively slowly through the channels, where it is then present as an active substance.
- lipid-soluble active ingredients such as. B. Taxol
- lipid phase lipid-soluble active ingredients
- the systems with a proportion of MPEG-DSPE or DMPA were prepared analogously - however, 5 mol% MPEG-DSPE or DMPA was added to the molten amount of monoolein. The powdered additional lipid was dissolved in the liquid MO by vigorous shaking. 40% by weight of CP solution were then added again and the sample was homogenized as described above.
- F98 tumor cells were used which are sensitive to carboplatin.
- the sample preparation is identical to the procedure described in Example 1.1.1. Samples were prepared that contained different carboplatin concentrations. (0, 5, 10, 20 and 40 ⁇ g carboplatin per 300 mg cubic phase). Compared to measuring the model release kinetics very low carboplatin concentrations were used because the biological systems are extremely sensitive to the cytostatic.
- FIG. 3 shows that the monoolein, 40% by weight carboplatin solution release system has cytotoxicity on the different tumor cell lines F98 and CC531. Colon carcinoma cells are apparently far less sensitive to carboplatin.
- carboplatin 5 ⁇ g carboplatin killed about 65% of the cells after 72 h
- Figure 4 clearly shows the effect of the released carboplatin on the tumor cell lines.
- the effect of the F98 cell is comparable to that of the pure cubic system.
- Already a quantity of 5 ⁇ g CP results in a cell elimination of about 65% after 72 hours.
- the colon carcinoma cell is obviously more sensitive to the modified release system.
- 5 ⁇ g carboplatin is also sufficient to kill 65% of the cells.
