[0033] Experimental example 1 Prescription Screening Experiment
[0034] 1. Instruments and raw materials
[0035] Tablet press: (Model: DP30);
[0036] Disintegration instrument: (model: ZB6);
[0037] Balance: (Model: FA1004, manufacturer: Shanghai Balance Instrument Factory).

[0041] 2 methods:
[0042] (1), disintegrant selection:
[0043] In the case of constant drug powder and filler in this prescription, the drug powder and disintegrant were mixed according to the ratio of 1:1, compressed into tablets, and the disintegration time was used as the investigation index. The results are shown in Table 2:
[0044] Table 2 Screening of disintegrants
[0045]
[0046] The results showed that the disintegration effects of cross-linked polyvinylpyrrolidone, cross-linked sodium carboxymethyl cellulose, sodium carboxymethyl starch, low-substituted hydroxypropyl cellulose and microcrystalline ...
experiment example 2
[0067]Experimental Example 2 Bioequivalence Experiment
[0068] Dispersible tablet of the present invention has carried out human body bioequivalence test result with certain listed common tablet and shows: the InC of two kinds of preparations max 、InAUC 0→24 The three-factor analysis of variance showed that the InC of the two preparations max 、InAUC 0 →24 There are significant differences. The average maximum blood drug concentration of the tested preparations was higher than that of ordinary tablets. T of the two formulations max Using non-parametric test, the test results have significant difference, the peak time T of the tested preparation max Significantly faster than conventional tablets; InC max 、InAUC 0→24 The double one-sided t test showed that the dispersible tablet was superior to the ordinary tablet.
[0069] The following embodiments can achieve the effects of the above experimental examples.
