    • The present invention relates to a stabilized plant protecting agent suspension which can be characterized by containing 10 to 60% by weight of one or more active ingredients, 30 to 5% by weight of oily layer, 0 to 10% by weight of emulsifyer, 10 to 20% by weight of conventionally used excipient and water needed to 100% by weight while by increasing solid concentration oil concentration decreases.The invention also provides a process for the preparation of a stabilized plant protecting agent suspension by adding oil and optionally an emulsifyer and/or water containing layer to a suspension of a suitable particle size of the active ingredient and water soluble excipients, such as surfactants, optionally emulsifiers, dispersing agents, viscosity modifying agents, protective colloids and mixing together the suspension layer and the layer containing the oil with a stirrer of great shearing force and optionally adding to the obtained stabilized suspension further excipients, e.g. viscosity modifying agents, anti-foaming agent, protective colloid and dispersing agent.
    • 本发明涉及一种稳定的植物保护剂悬浮液,其特征在于含有10至60重量%的一种或多种活性成分,30至5重量%的油层,0至10重量%的乳化剂,10 至20重量%的常规使用的赋形剂和水需要100重量%,同时通过提高固体浓度油浓度降低。 本发明还提供了一种制备稳定的植物保护剂悬浮液的方法,其通过将油和任选的乳化剂和/或含水层添加到适合粒度的活性成分和水溶性赋形剂如表面活性剂的悬浮液中, 任选的乳化剂,分散剂,粘度调节剂,保护胶体,并将悬浮液层和含有油的层与具有大剪切力的搅拌器混合在一起,并任选地将所得稳定悬浮液中的其它赋形剂 粘度调节剂,消泡剂,保护胶体和分散剂。

    • This invention provides liposomic composition, containing as active ingredient (-)-N-.alpha.-dimethyl-N-(2-propynylphenylethylamine) (selegilin) and/or salt thereof. This composition contains: 0.1-40% by weight of selegilin and/or a salt thereof, 2 to 40% by weight of lipids, preferably phospholipids, 0 to 10% by weight of cholesterol, 0 to 20% by weight of an alcohol, 0 to 25% by weight of a glycol, 0 to 3% by weight of an antioxidant, 0 to 3% by weight of a preserving agent, 0 to 2% by weight of a viscosity influencing agent, 0 to 50% by weight of cyclodextrin or a cyclodextrin derivative and 30 to 90% by weight of water. This invention relates to pharmaceutical composition, containing the liposomic composition described and if desired, usual filling and diluting agents and other auxiliaries, preferably in oral, parenteral or transdermal form. This invention provides the process for the preparation of liposomic compositions containing selegilin and/or salt thereof. Accordingly liposomic composition of this invention may be administered for the treatment of Alzheimeir's disease, Parkinson's disease, depression, stroke, motion sickness or myelitis.
