B) by tablet, with agate mortar, gently grind into fine powder solid, progress XRPD characterizations compare it and are made before and after tablet
Crystal form variation.
XRPD the result is shown in Figure 1s 3 and Figure 14, display:Compared with the crystal form before tabletting, the crystalline substance of crystal form I and crystal form II after tabletting
Type does not change;The auxiliary material and technique of 24 tablet of embodiment are on the crystal form of crystal form I and crystal form II without influence.
Embodiment 25
The crystal form I tablets prepared by 24 method of embodiment and crystal form II tablets are taken, carries out dissolution rate comparative experiments.
With reference to《Chinese Pharmacopoeia》The leaching condition of " Benorilate Tablets " measures dissolution rate in 2010 editions, using paddle method, with 900mL
1% lauryl sodium sulfate (SDS) aqueous solution as dissolution medium, 37 DEG C, rotating speed of agitator 100r/min of temperature, respectively
3mL is sampled when 10min, 20min, 30min, 60min, is supplied after every sub-sampling with 1% SDS solution, when HPLC measures each
Between put sample concentration, calculate dissolution percentage.Dissolution data result is shown in Table 5.
5 crystal form I tablets of table, the dissolution data of crystal form II tablets
The results show of table 5:Dissolution percentage of the tablet in 30min of the crystal form II of the present invention up to more than 95%,
And dissolution percentage of the tablet of known crystal form I in 30min is less than 85%, therefore the dissolution of the tablet of the crystal form II of the present invention is fast
Rate is faster than the dissolution rate of the tablet of known crystal form I.Illustrate when preparing quick releasing formulation, the preparation of crystal form II of the invention is more easy to
Reach the requirement of product.
