2樓說(shuō)的不對(duì),聚氧乙烯蓖麻油和乙醇是taxol的配方 Paclitaxel is currently formulated in a vehicle composed of 1:1 blend of Cremophor EL (polyethoxylated castor oil) and ethanol which is diluted with 5–20-fold in normal saline or dextrose solution (5%) for administration. This formulation is stable in unopened vials for 5 years at 4 °C. However, lots of problems employing this vehicle have been reported. 聚氧乙烯蓖麻油會(huì)形成類(lèi)似膠束的結(jié)構(gòu),包裹紫杉醇 |

形成的膠束在用生理鹽水稀釋的過(guò)程,或者制成制劑后靜注入血稀釋過(guò)程,會(huì)不會(huì)由于低于CMC而膠束破壞,紫杉醇析出。 發(fā)自小木蟲(chóng)IOS客戶(hù)端 |
