Description
Technical Field
The invention relates to the technical field of pharmaceutical preparations, in particular to a tacrolimus sustained-release preparation and a preparation method thereof.
Background
Tacrolimus is firstly extracted from broth fermentation products of streptococcus bulgaricus in 1984 by Japan Tacroze pharmaceutical company, and is a three-pillar product for resisting graft immune rejection reaction at home and abroad together with cyclosporine and mycophenolate mofetil. Tacrolimus was approved by the FDA for marketing in the United states in 1995 and entered the Chinese market in 1998. Tacrolimus and cyclosporin A are both calcium neuraminidase inhibitors, have the similar and wider immunosuppressive action as cyclosporin A, achieve the effect of comprehensively inhibiting T lymphocytes mainly by inhibiting the release of interleukin-2 (L-2), have the efficacy 10-100 times higher than that of cyclosporin A, and have fewer adverse reactions. At present, tacrolimus is widely applied to transplantation of solid organs such as liver, pancreas, kidney, heart, lung and the like, becomes a first-line medicament for organ transplantation immunosuppressive therapy, plays a positive role in treating autoimmune diseases such as Atopic Dermatitis (AD), systemic Lupus Erythematosus (SLE), autoimmune eye diseases and the like, and has high clinical application value.
However, tacrolimus has a Narrow Therapeutic Index (NTI), and blood levels of tacrolimus must be maintained within certain levels, with too high a concentration increasing the risk of toxic reactions and too low a concentration increasing rejection. The tacrolimus sustained-release preparation can lead the blood concentration of the tacrolimus to be stable, reduce the blood concentration CV and reduce the times of taking the medicine, and has higher clinical medication advantages. However, the tacrolimus slow-release preparation has higher difficulty in prescription and production process, and the difficulties in the prescription and process are as follows: (1) The solubility of the tacrolimus in water is very poor (about 1.58 mu M of tacrolimus is dissolved in water at 25 ℃), and the selected auxiliary materials need to have a slow release function while the tacrolimus is dissolved; (2) the preparation product is easy to cause ethanol pouring; (3) The solubilization slow-release auxiliary materials and the main drugs can be fully combined in the development process, and the process suitable for industrialization is difficult. Therefore, it is of great importance to develop a sustained release preparation which is suitable for industrial production, can slowly release tacrolimus and does not cause ethanol dumping.

Ethanol pour test
Dissolution medium:
pH1.2 hydrochloric acid solution +0.005% HPC (5% concentration): 95% pH1.2 hydrochloric acid solution +5% anhydrous ethanol by volume ratio, and stirring well.
ph1.2 hydrochloric acid solution +0.005% hpc (20% concentration): according to the volume ratio, 80 percent of hydrochloric acid solution with pH1.2 +20 percent of absolute ethyl alcohol is stirred evenly.
pH1.2 hydrochloric acid solution + 0.005%/HPC (40% concentration): according to the volume ratio, 60 percent of hydrochloric acid solution with pH1.2 +40 percent of absolute ethyl alcohol is stirred evenly.
The dissolution rate at each time point was measured as above. The results are shown in tables 3 to 5.
