【摘 要】 目的:比較不同廠家生產(chǎn)的鹽酸小檗胺片在不同溶出介質(zhì)中的溶出度。 方法:根據(jù)《中國(guó)藥典》2015年版溶出度測(cè)定方法第二法,以人工胃液(不加酶)和人工腸液(不加酶)為溶出介質(zhì),轉(zhuǎn)速為50 r/min,于279 nm處采用紫外分光光度法測(cè)定吸光度并計(jì)算溶出度,采用相似因子、主成分分析和分層聚類(lèi)分析對(duì)溶出度進(jìn)行數(shù)據(jù)分析。結(jié)果:鹽酸小檗胺片在人工胃液(不加酶)和人工腸液(不加酶)中累積溶出度在40 %~50 %之間。結(jié)論:相似因子、主成分分析和分層聚類(lèi)結(jié)果表明,在相同溶出條件下鹽酸小檗胺糖衣片與薄膜衣片有不同的溶出行為,且薄膜衣片比糖衣片更加穩(wěn)定,可見(jiàn)鹽酸小檗胺薄膜衣片規(guī)格的工藝較糖衣片更加合理。

Abstract:Objective To compare the dissolution of Berbamine Hydrochloride tablets by different manufacturers in different dissolution media (artificial gastric and intestinal juice). Methods Samples were collected with the artificial gastric juice (without enzyme) and the artificial intestinal fluid (without enzyme) as solvent and rotation speed of 50r·min-1 according to second dissolution determination method(slurry method)stated in Chinese Pharmacopeia (2015 edition).The absorbance of samples was determined by UV spectrophotometry at detection wavelength of 279 nm.The data analysis about the dissolution was conducted by similarity factor, principal component analysis (PCA) and hierarchical clustering analysis (HCA). Results The dissolution of Berbamine Hydrochloride tablets is 40%~50% in the artificial gastric juice (without enzyme) and the artificial intestinal fluid (without enzyme).Conclusionns The analysis results of similarity factor, principal component analysis (PCA) and hierarchical clustering analysis (HCA) showed that in the same conditions the dissolution of sugar-coated tablets and the film-coated tablets have the different dissolution behavior, and the film-coated tablets is more stable than sugar-coated tablets.So the process of Berbamine Hydrochloride film-coated tablets is more reasonable than sugar-coated tablets.

鹽酸小檗胺(Berbamine Hydrochloride)是從小檗科植物甘肅小檗(Berberis kansuensis Schneid.)[1]同屬植物中分離得到的一種天然來(lái)源的化合物,是一種雙芐基異喹啉類(lèi)生物堿,也是一種天然來(lái)源的鈣調(diào)素拮抗劑[1],在臨床上常被用于治療各種原因引起的白細(xì)胞減少癥。前期研究表明,鹽酸小檗胺具有輔助鹽酸小檗堿降低四氧嘧啶小鼠空腹血糖的增效作用[2],糖尿病患者發(fā)生青光眼[3]、白內(nèi)障[4]的比例顯著增高,有研究表明鹽酸小檗胺具有青光眼視神經(jīng)保護(hù)作用[3],外用小檗胺滴眼液對(duì)糖尿病性白內(nèi)障具有顯著的防治作用[5],表明鹽酸小檗胺在治療糖尿病眼病的新藥研發(fā)方面具有重大的意義。
目前,鹽酸小檗胺上市劑型僅有片劑,有薄膜衣片、糖衣片兩種規(guī)格,其溶出行為可能因?yàn)榘虏牧系牟町惗煌琜6-7],由于鹽酸小檗胺對(duì)青光眼視神經(jīng)保護(hù)作用具有劑量依賴(lài)性[3],與血藥濃度有關(guān),在體外又與溶出度相關(guān)。但是,有關(guān)鹽酸小檗胺片的溶出度試驗(yàn)卻鮮有報(bào)道,為了了解鹽酸小檗胺在胃腸道的溶出行為,預(yù)測(cè)其生物利用度,在前期對(duì)鹽酸小檗胺的溶解度和油水分配系數(shù)試驗(yàn)結(jié)果的基礎(chǔ)上,本研究模擬體外胃、腸道環(huán)境,對(duì)鹽酸小檗胺片的溶出度進(jìn)行測(cè)定,為鹽酸小檗胺片的包衣工藝選擇提供依據(jù)。
