作者分析了市场上58种口服溶液,悬浮液和电解质溶液渗克分子浓度。每种药品用无菌蒸馏水1:10的比例稀释到100μl 并充分混匀.每份样品稀释液取10μl(至少取2份)用蒸汽压渗透压力测定法测定其(重量)渗克分子浓度.仅有8种药品(10%)的(重量)渗克分子浓度小于或者等于1000mOsm/kg(即与市场上的肠液配方值近似)。其它药品的(重量)渗克分子浓 The authors analyzed the osmolality of 58 oral solutions, suspensions and electrolyte solutions on the market. Each product is diluted to 100 μl with sterile distilled water at a ratio of 1:10 and thoroughly mixed with 10 μl (at least 2 parts) of each sample dilution is determined by osmotic pressure measurement for its osmolality. Only 8 drugs (10%) have a (weight) osmolality of less than or equal to 1000 mOsm / kg (ie similar to the intestinal fluid formulation on the market). Other drugs (weight) oily molecules concentrated
