    • The invention relates to a method for producing highly pure 2,4'-dimethyl-3-piperidino-propiophenone (tolperisone) (formula I) and the pharmaceutically acceptable salts, hydrochlorides, and hydrates thereof. Said method allows the content of the undesired byproduct 2-methyl-1-(4-methyphenyl) propenone (4-MMPPO) to be kept significantly lower than in previously known methods. The invention further relates to active substance formulations which contain tolperisone and are suitable, among other things, for producing combination preparations used for treating patients suffering from Alzheimer's disease. The invention also relates to topical formulations, controlled release (CR) formulations, and transdermal therapeutic systems, such as active substance patches, which contain less than 50 ppm, preferably less than 10 ppm, more preferably less than 7 ppm, and most preferably less than 3 ppm or 0 ppm (i.e. less than the detectable amount) of the undesired byproduct 2-methyl-1-(4-methylphenyl) propenone (4-MMPPO) in relation to 100 percent by weight of active substance.
    • 2,4'-二甲基-3-哌啶子基丙酰苯(托哌酮)和它们的药物上可接受的盐的生产涉及转换4-甲基苯基乙基酮用piperidinhydrochloride和在溶剂中的一种或多种酸作为催化剂存在下的1,2-二氧戊环。 甲苯哌丙酮粗产物在反应混合物冷却后过滤以药物相容的水力氯化物,水合物和加成盐的形式存在。 的一部分通过所述托哌酮粗产物进行重结晶,在反萃溶剂和吸收的存在而降低,以2-甲基-1-(4-甲基苯基)propenones(4- MMPPO)。 独立权利要求中包括了:(1)用于制备药物制剂,其涉及不含水的条件下,在一种或多种溶剂具有游离水基添加剂以药物相容的酸的形式掺合托哌酮作为活性物质的方法,优选 柠檬酸; (2)一种控释(CR)配制,包括一个芯部件和延迟涂层; 和(3)经皮治疗系统,其包括一个储液层含有作为托哌酮以纯的形式活性的活性物质:神经保护;. 精神药物。 作用机理:没有给出。
