NACを、ローラーコンパクターを用いて乾式造粒した。この機械内では、このプロセスの2つの別々の段階が行われ、粉末は最初に、該粉末に力を加えながらそれをウエハーに変換させる2つの二重反転ローラーを通過し、その後、該ウエハーは、等級に分けられた顆粒が生み出されるふるいを備えた小さなミルを通過する。
実施例1に従って製造された顆粒を、ヒドロキシプロピルセルロース、微結晶性セルロース、クロスポビドンおよびコロイドシリカと9分間混合し、その後、ステアリン酸Mgとさらに1分間混合した。生成した混合物を、ロータリー打錠機を用いて、20 KNの圧縮力および約3 KNの予圧を加えて圧縮した。
本発明による活性成分の乾式造粒手順を用いて製造した、表2に示す組成を有する6つの錠剤を含むパックを開く際に硫黄臭が存在したかどうかを確認するために、喫煙者、アレルギー患者、喘息患者および妊婦を除外するように適切に30人を選択して試験を実行した。
