The invention relates to controlled release pharmaceutical compositions. These contain as active ingredient valproic acid, a salt of valproic acid, an ester of valproic acid, Valpromide, or any other pharmaceutically acceptable derivative of valproic acid which upon administration to humans provides a serum level of valproic acid, in combination with an additive which is selected from physiologically acceptable polymeric substances and from native proteins. The active ingredient is usually in the range of from 10 to 80 weight per cent. The novel pharmaceutical compositions are prepared by applying a high pressure to a mixture of the ingredients. They result in a prolonged serum level of the active ingredient.
本发明涉及控释药物组合物。它们含有作为活性成分的丙戊酸、丙戊酸的盐、丙戊酸的酯、丙戊酸钠或任何其他药学上可接受的丙戊酸衍生物,在给人用药后可提供一定水平的丙戊酸血清,同时还含有一种添加剂,该添加剂选自生理学上可接受的聚合物质和本地蛋白质。活性成分的重量百分比通常在 10%至 80%之间。新型药物组合物是通过对成分混合物施加高压来制备的。它们能延长血清中活性成分的含量。
