    • The present invention relates to pharmaceutical compositions for the sustained release of pharmacologically active compounds and methods of their manufacture and use. Sustained release times of 10-12 days have been achieved with the present invention. The present invention provides microcrystal compositions. The microcrystals comprise pharmacologically active compounds and are contained within a phospholipid layer which contains a unique combination of phospholipids. The present invention may be applied to a wide range of pharmaceutical compositions which may be rendered suitable for injection. The microcrystals are of varying sizes. At least 50 percent of the microcrystals are from 0.5 &mgr;m to about 3.0 &mgr;m in diameter, at least ten percent of the microcrystals are from about 3.0 &mgr;m to about 10 &mgr;m in diameter, and the composition contains microcrystals which are greater than 10 &mgr;m in diameter. In preferred embodiments, at least about 1% of the microcrystals are greater than 10 &mgr;m in diameter. The compositions and methods are useful for treating respiratory diseases, infections, inflammation, and pain in a variety of mammals. The compounds and methods are also able to sharply reduce the toxicity of drug compounds.
    • 本发明涉及用于药物活性化合物缓释的药物组合物及其制造和使用方法。 本发明实现了10-12天的持续释放时间。 本发明提供微晶组合物。 微晶包含药理活性化合物,并且包含在含有磷脂独特组合的磷脂层中。 本发明可以应用于可适于注射的广泛范围的药物组合物。 微晶具有不同的尺寸。 至少50%的微晶直径为0.5μm至约3.0μm,至少10%的微晶直径为约3.0μm至约10μm,组合物含有直径大于10μm的微晶 。 在优选的实施方案中,至少约1%的微晶直径大于10um。 组合物和方法可用于治疗各种哺乳动物的呼吸系统疾病,感染,炎症和疼痛。 化合物和方法也能够大大降低药物化合物的毒性。
