杜仲緩釋片制備及質(zhì)量標(biāo)準(zhǔn)的研究

杜仲緩釋片制備及質(zhì)量標(biāo)準(zhǔn)的研究摘要：

杜仲緩釋片是一種新型中藥制劑，采用了多種技術(shù)，如微?；夹g(shù)、膜包覆技術(shù)、粘結(jié)劑技術(shù)等，旨在提高杜仲的藥效和緩解劑量的持續(xù)時(shí)間，使其更適合臨床應(yīng)用。本研究主要研究了杜仲緩釋片制備的工藝及其質(zhì)量標(biāo)準(zhǔn)。通過(guò)對(duì)不同工藝參數(shù)的考察，確定了制片工藝的最佳條件，以及對(duì)緩釋片質(zhì)量的主要影響因素。同時(shí)，對(duì)緩釋片的質(zhì)量進(jìn)行了常規(guī)的物理化學(xué)分析、質(zhì)量評(píng)價(jià)和穩(wěn)定性研究。

結(jié)果表明，最佳的制片工藝條件為：杜仲微粒粉末的粒徑為15-20um，外層包膜的加料量為20%，粘結(jié)劑的加入量為10%，顆粒干燥溫度為40℃，顆粒分散后再次噴涂外層包膜。通過(guò)各項(xiàng)物理化學(xué)分析和質(zhì)量評(píng)價(jià)，緩釋片的質(zhì)量符合要求，其中總生物堿含量為3.52%，總黃酮含量為4.28%。穩(wěn)定性研究表明，緩釋片具有較好的穩(wěn)定性，保持其特性至少12個(gè)月。
