Standard deviation ????0.173 ??2.79 ??2.95 ??3.23 ??2.47 ??2.20 ??2.96 ??3.38 ??0.81
As seen knot is, the self-control slow releasing tablet is compared with the release in vitro degree of commercially available yufeng ningxin tablets, yufeng ningxin pian, has tangible slow releasing function.
From drug release behavior, commercially available yufeng ningxin tablets, yufeng ningxin pian is complete release in 6 hours, and the self-control slow releasing tablet then lasted till to have slow releasing function 12 hours.
From the deviation of data, the standard deviation of each time point data of commercially available yufeng ningxin tablets, yufeng ningxin pian is bigger, and the data standard deviation of self-control slow releasing tablet is less, and quality controllability is good.
Experimental example 4 slow releasing tablet of the present invention inside and outside correlation tests
Puerarin curve when the intravital medicine of dog meets open two-compartment model, according to PA (Fa) in the Loo-Riegelman Equation for Calculating body, PA (Fa) in the same time dog body is returned with batch Radix Puerariae flavone slow releasing tablet release in vitro percentage rate (Fd), correlation coefficient is 0.9898, the inside and outside is relevant, can be according to absorbing state in the release in vitro degrees of data predictor.
The dependency of experimental example 5 method of quality control of the present invention relatively
Carry out the experiment of release in vitro degree according to first method of two drug release determination methods of Pharmacopoeia of the People's Republic of China version in 2000, compare ultraviolet spectrophotometry (detection total flavones), high performance liquid chromatography (HPLC, detection puerarin), high performance capillary electrophoresis (HPCE, detection puerarin) is estimated the dependency of release in vitro degree.
