Description
上記マトリクス剤の含量が25重量%未満の場合、薬物の放出が早すぎる。対照的に、75重量%を超過する場合、薬物の放出が非常に遅く、錠剤のサイズが非常に大きくなるため、投与が難しい。
上記コーティング層は錠剤の総重量に対して、0.5〜15重量%、好ましくは1〜10重量%、更に好ましくは2〜5重量%である。コーティング層の含量が0.5重量%未満の場合、メトホルミンの含量が低下しやすくなり、対照的に、15重量%を超過する場合、崩壊時間が非常に長くなるためGI管上部での吸収が難しくなる。
下記表1に表されるように、塩酸メトホルミン、ヒドロキシプロピルメチルセルロースおよび軽質無水ケイ酸を混合した。混合物を、16〜17MPaの圧力でローラー圧縮をしてスラッグ化した。このスラッグを14メッシュふるいでふるいにかけた後、ステアリン酸ナトリウムを入れて混合し、錠剤を製造した。錠剤にHi−Coater(SFC−30N、Sejong Machinery、韓国)を用いてオパドライ OY−C−7000Aをコーティングしてコーティング層を形成し、メトホルミンが500mg含有されたメトホルミン徐放性錠剤(Metformin XR tablet 500mg)を製造した。
下記表1に表されるように、塩酸メトホルミン、カルボキシメチルセルロースナトリウム、アビセルPH101および軽質無水を混合し、実施例1の製造方法と同一の方法で、メトホルミンが500mg含有されたメトホルミン徐放性錠剤(Metformin XR tablet 500mg)を製造した。
下記表1に表されるように、塩酸メトホルミン、グアーガムおよび軽質無水を混合し、実施例1の製造方法と同一の方法で、メトホルミンが500mg含有されたメトホルミン徐放性錠剤(Metformin XR tablet 500mg)を製造した。
下記表1に表されるように、塩酸メトホルミン、ヒドロキシプロピルメチルセルロースおよび軽質無水を混合し、実施例1の製造方法と同一の方法で、メトホルミンが750mg含有されたメトホルミン徐放性錠剤(Metformin XR tablet 750mg)を製造した。
下記表1に表されるように、塩酸メトホルミン、ヒドロキシプロピルメチルセルロース、軽質無水ケイ酸およびステアリン酸ナトリウムを混合し、直接圧縮法で圧縮して錠剤を製造し、上記錠剤にHi−Coater(SFC−30N、Sejong Machinery、韓国)を用いてオパドライ OY−C−7000Aをコーティングしてコーティング層を形成し、メトホルミンが500mg含有されたメトホルミン徐放性錠剤(Metformin XR tablet 500mg)を製造した。
下記表1に表されるように、塩酸メトホルミン、ヒドロキシプロピルメチルセルロース、軽質無水ケイ酸およびステアリン酸ナトリウムを混合し、比較例1の製造方法と同一の方法で、メトホルミンが750mg含有されたメトホルミン徐放性錠剤(Metformin XR tablet 750mg)を製造した。
上記実施例1および4の原料を混合し、16〜17MPaの強い圧力でスラッグ化した後、顆粒化し、半製品とした。半製品と比較例1および2の圧縮性と流動性を下記のような方法で比較した。
本発明により製造されたメトホルミン徐放性錠剤(実施例1)と市販されている対照製剤(BMS社、Glucophage XL、米)の溶解像を比較し、パドル法にて溶出性を測定し、その結果を図1に表した。
本発明のメトホルミン徐放性錠剤(実施例1)と市販されている対照製剤(BMS社、Glucophage XL、米)の生物学的同等性を比較し、その結果を図2と下記表3に表した。
本発明は好ましい実施形態を引用して詳細に説明されたが、それに対し、請求項として添付された、本願の意図と目的から離れない範囲で、当業者により様々な変更と代用が成されることが可能である。
