OBJECTIVE:To optimize the formulation of Mirabegron sustained-release tablets. METHODS:Using polyethylene oxide(PEO)and hydroxypropylmethyl cellulose(HPMC K4M)as the sustained release matrix,Mirabegron sustained-release tab-lets were prepared by powder direct compression technology. Using 1,3,5,7 h accumulative release rate as indexes,the amounts of PEO,HPMC K4M and OPADRY? were optimized by composite design-response surface method,and then validated. Accumula-tive release rates of sustained-release tablet and original tablet (MyrbetriqTM) were compared in different pH mediums (water,pH 1.0 simulated gastric fluid,pH 4.5 acetate buffer solution,pH 6.8 phosphate buffer solution) at different rotation rates (100,50 r/min),and similiar factor f2 was calculated to fit drug release model of sustained-release tablet. RESULTS:In the optimized firmu-lation each Mirabegron sustained-release tablet contained mirabegron 25 mg,PEO 108.02 mg,HPMC K4M 21.69 mg,OPADRY? 2.27%. Relative error of accumulative release rates at 1,3,5,7 h to predicted value were 4.78%,3.48%,0.69% and -1.41%, respectively. f2 of release curves of sustained-release tablet and original tablet were higher than 65 in different pH medium at differ-ent rotation rates. The drug release of sustained-release tablet was fitted to zero-order release equation. CONCLUSIONS:Mirabe-gron sustained-release tablet by optimized technology is similar to original tablet in drug release behavior.

Objective:To investigate the distribution characteristics of syndrome types of traditional Chinese medicine (TCM) in essential hypertension and to explore the distribution rule of TCM syndromes. Methods: A multicenter, large-sample survey method of clinical epidemiology was applied to choose the patients with essential hypertension from North, Middle, and South China. A questionnaire was designed and filled in, then 477 untreated patients with first-diagnosed essential hypertension were selected and the information was recorded into FileMaker database. A cluster analysis method was utilized to study the TCM syndrome distribution rule of essential hypertension. Results: Two-step cluster analysis was done from 3 to 7 clusters. Seven clusters were appropriate, which included deficiency of heart and kidney qi, hyperactivity of liver-yang, deficiency of yin and yang, stagnation of phlegm-dampness, phlegm-heat (subtype of stagnation of phlegm-dampness), blood stasis obstructing collaterals, and other syndromes. The symptoms presenting high percentage in each cluster were more significant in TCM theory. The syndromes of hyperactivity of liver-yang (24.1%) and stagnation of phlegm-dampness (27.1%) presented the high percentages, and deficiency of heart and kidney qi (10.1%), deficiency of yin and yang (8.4%), and blood stasis obstructing collaterals (9.0%) presented the low percentages. Conclusion: As compared with the current syndrome differentiation criteria, two-step cluster analysis results not only include the syndromes of deficiency of yin and yang, hyperactivity of liver-yang, stagnation of phlegm-dampness, but also cover qi deficiency and blood stasis.
