目前将0.8～1.2μm 的微孔滤膜用于大输液的精滤,易被堵塞。我院制剂室采用不同孔径的微膜联合应用,基本解决了易被堵塞的问题,有效地提高了过滤速度,收到了较满意的效果。过滤1500L输液溶速依然不减,澄明度合格率由90%提高到95%,微粒数达到了药典规定的限度,也减少了每 Currently 0.8 ~ 1.2μm microporous membrane for large infusion of fine filter, easily blocked. Our hospital preparation room with different aperture of the micro-membrane joint application, the basic solution to the problem of easy to be blocked, effectively improve the filtration speed, received more satisfactory results. Filtration 1500L infusion dissolution rate is still diminished, clarity pass rate increased from 90% to 95%, the number of particles reached the limits prescribed by the Pharmacopoeia, but also reduces each
