RESUMEN
Objective To prepare isophenylcyclopentylamine hydrochloride capsules and evaluate its quality. Methods The suitable excipients were selected by the drug-excipient compatibility test,and after the formulation and preparation process design and screening,the micromeritic property and hygroscopicity of contents of capsules as well as the basic performance and stability of is-ophenylcyclopentylamine hydrochloride capsules were evaluate. Results The selected formulation was composed of isophenylcyclo-pentylamine hydrochloride 10 mg,anhydrous dibasic calcium phosphate 128.7 mg,mannitol 128.7 mg and aerosil 2.7 mg.The angle of repose of intermediate powders was(30.71±1.09)°,aerated and packed bulk densities were(0.76±0.01)and(0.90±0.02)g/ml re-spectively,Hausner value was 1.19±0.01,Carr′s index was(15.86±1.05)%,indicating good flowability and filling property as well as relatively low humidity.The contents,uniformity of contents and dissolution of capsules fulfilled the requirements.The quality of ca-pusles kept well in the 6-month accelerated and long-term stability test.Conclusion The formulation is simple and reasonable,and the preparation process showed a good reproducibility,which might be suitable for industrialization.
RESUMEN
<p><b>OBJECTIVE</b>To explore the correlation between Chinese medical syndrome types of Wilson's disease (WD) and clinical materials as well as physical and chemical indices.</p><p><b>METHODS</b>Totally 116 WD patients were typed by Chinese medical syndrome. The correlation between Chinese medical syndrome types and clinical materials as well as physical and chemical indices were analyzed using binary stepwise Logistic regression by SPSS 19.0 Software, taking the common Chinese medical syndrome types as the dependent variable and clinical materials as well as physical and chemical indices as the independent variables.</p><p><b>RESULTS</b>Gan-Galibladder dampness-heat syndrome (GGDHS, 35.3%). Gan-stagnation and Pi-deficiency syndrome (GSPDS, 13.8%), Gan-Shen yin deficiency syndrome (GSYDS, 13.8%), and phlegm-dampness retention syndrome (PDRS, 12.1%) were most often seen. GGDHS was positively correlated with grade of K-F ring, total bilirubin (TBIL), alanine transaminase (ALT), laminin (LN) (P < 0.01). GSYDS was positively correlated with TBIL (P < 0.01). PDRS was positively correlated with clinical types, ceruloplasmin (CP), aspartate aminotransferase (AST), and total protein (TP) (P < 0.01, P < 0.05). Qi blood deficiency syndrome was positively correlated with disease course, blood ammonia, blood urea nitrogen (BUN), and LN (P < 0.01, P < 0.05).</p><p><b>CONCLUSIONS</b>Chinese medical syndrome types were correlated with clinical materials, physical and chemical indices in WD patients, which could provide experimental reference for Chinese medical syndrome typing. GGDHS, GSPDS, GSYDS, and PDRS were most often seen.</p>
