Correlation Research between the Drug Dissolution Test and Blood Drug Concentration in Vivo and Antipyretic Effect for Ibuprofen Sustained-Release Capsules
摘要
Abstract
Objective To set up the new method for drug dissolution test of Ibuprofen sustained-release capsules(ISRC)and evaluate the correlation between the drug dissolution tested by new method and the drugblood concentration in vivo and the antipyretic ef-fect. Methods ISRC were selected for experimental drugs. The new method of ISRC dissolution test was established,which included dis-solution medium pH=7. 6 buffer of phosphate,dissolution device one of paddle method,the speed of the paddle 50 r/min. To compared with the method of 2010 edition of China pharmacopoeia PartⅡ,the dissolution of ISRC tested by two method were monitored with fiber-optic in site dissolution testing equipment. The oral of single dosage of ISRC was used to rabbits,the drug blood concentrations of different time were measured. The model of rabbit fever was adopted by endotoxin,and the antipyretic effect of ISRC was checked. Results The course of drug dissolution tested by the new method in vitro emerged unsustained-release effect. The time of the percent of close to the largest accumulation drug dissolution of the new method in vitro,and of the peak drug blood concentration in vivo was better correlation. The peak drug blood concentration and the largest antipyretic effect were consistent. Conclusion When pH value of dissolution medium is increased,the process of sustained-release of ISRC in vitro is changed and otherwise its in vitro-in vivo correlation would be better than the results of the method in the China Pharmacopoeia.关键词
