原始语种摘要: This work addressed solubility and membrane permeability problems of Biopharmaceutics Classification System ( BCS ) Class IV glycoside scutellarin ( SG ) by developing a nanosuspension of its aglycone scutellarein ( S ) as a precursor. An S nanosuspension containing poloxamer 188 was prepared using antisolvent precipitation where hydroxypropyl‐β‐cyclodextrin was utilized as a lyophilizing protectant. Particle size and polydispersity index after redispersion were 342.6 ± 18.2 and 0.32 ± 0.06 nm, respectively. The dissolution rate of the S nanosuspension was superior compared with the physical mixture. No free S , but SG and SG 's isomer were detected in plasma following oral delivery of SG or S , S nanosuspension or physical mixture of S . The C max values of SG after dosing...
