Sustained release preparation composition

The invention relates to a pharmaceutical composition. The pharmaceutical composition comprises liquid oil, a pharmaceutically acceptable gelator, a pharmaceutically acceptable stabilizer and a pharmaceutically active ingredient. The pharmaceutical composition is especially suitable for development of pharmaceutical preparations with anesthesia and analgesic activity, and has more advantages compared with other sustained-release analgesic systems, for example, release of analgesic active ingredients is continuous and stable, injection administration can be achieved, the pharmaceutical composition is suitable for stable and convenient local administration, patient tolerance is good, and side effects are few. 本发明涉及一种药物组合物，包含液体油，药学上可接受的凝胶因子，药学上可接受的稳定剂和药学上的活性成分。所述药物组合物尤其适用于具有麻醉、镇痛活性的药物制剂开发，相对于其他缓释镇痛药体系具有更多的优势，例如对于镇痛活性成分的释放持续稳定，不仅可以注射给药，而且适用于稳定便捷的局部给药，患者耐受性好，副作用少。
