    • The invention relates to a method for producing pancreatin with reduced viral and microbial contamination, comprising the steps of (a) providing the pancreatin in solid form with a residual moisture of 0.5 weight % or less, down to almost zero, based on the pancreatin provided; (b) subjecting the pancreatin provided in step (a) to a heat treatment at a temperature of 84° C., preferably 80° C. and below; wherein, the biological activity of the pancreatin obtained in step (b) corresponds to at least 50% of the biological activity of the pancreatin provided in step (a); and the viral infectiousness of the pancreatin obtained in step (b) has been reduced by a factor of more than 1 log10 in comparison with the viral infectiousness of the pancreatin provided in step (a), as well as a pancreatin produced according to this method and its use for producing a medicine or a nutritional supplement.
    • 本发明涉及一种生产具有减少的病毒和微生物污染的胰酶的方法,其包括以下步骤:(a)基于所提供的胰酶,提供固体形式的胰酶,残留水分为0.5重量%或更少,至少几乎为零 ; (b)使步骤(a)中提供的胰酶在84℃,优选80℃及以下的温度下进行热处理; 其中,步骤(b)中获得的胰酶的生物活性对应于步骤(a)中提供的胰酶的生物活性的至少50%。 与步骤(a)中提供的胰酶的病毒感染性相比,步骤(b)中获得的胰酶的病毒感染性已经降低了大于1log10的因子,以及根据该方法制备的胰酶 及其用于生产药物或营养补充剂的用途。

    • A process for producing pellets which are markedly spherical and have a particle size in the range from 0.1 to 4 mm and an apparent density above 0.5 g/cm.sup.3, and which are composed of 90-100% by weight of an ephedrine derivative and 0-10% by weight of a pharmaceutical aid, entails suspending ephedrine derivative powder with an average particle size of from 0.5 to 50 .mu.m at 0.degree.-90.degree. C. with stirring in a water-immiscible non solvent with a boiling point in the range from 60.degree. to 160.degree. C., adding 5-60% by weight, based on the ephedrine derivative, of an agglomerating liquid while continuing stirring, and, if there has been previous heating, cooling to from -5 to 25.degree. C. at 5-40K per hour, with the stirring speed being adjusted after the agglomeration of the powder particles to a value which is necessary for the required average particle size, and removing and drying the resulting pellets. A drug which contains the active ingredient in the form of such pellets, with or without slowing of release, is also described.
