Abstract
本発明は、分散不良薬物の溶出性を改善する方法を提供し、それは、浮遊化剤を分散不良薬物に加えた造粒物を製造することにより達成される。
Description
その分散不良薬物としては、11−[4−[2−(2−ヒドロキシエトキシ)エチル]−1−ピペラジニル]ジベンゾ[b,f][1,4]チアゼピンまたはその塩、7β−[2−(アミノチアゾール−4−イル)アセトアミド]−3−[[[1−(2−ジメチルアミノエチル)−1H−テトラゾール−5−イル]チオ]メチル]セフ−3−エム−4−カルボン酸の1−(シクロヘキシロキシカルボニロキシ)エチルエステルまたはその塩などを挙げることができる。その塩としてはフマル酸塩あるいは塩酸塩などが挙げられる。
この11−[4−[2−(2−ヒドロキシエトキシ)エチル]−1−ピペラジニル]ジベンゾ[b,f][1,4]チアゼピンまたはその塩、また7β−[2−(アミノチアゾール−4−イル)アセトアミド]−3−[[[1−(2−ジメチルアミノエチル)−1H−テトラゾール−5−イル]チオ]メチル]セフ−3−エム−4−カルボン酸の1−(シクロヘキシロキシカルボニロキシ)エチルエステルまたはその塩は、特開昭63−8378号公報または特開昭60−218394号公報に記載の方法でそれぞれ製造することができる。
フマル酸クエチアピン230.26g、乳糖細末161.74g、ヒドロキシプロピルセルロース8gを秤取して混合後、万能混合攪拌機(三英製作所、5DMV型)内で50vol%エタノール100mLを添加して10分間攪拌造粒(自転速度122rpm、公転速度58rpm)した。この造粒物を円筒造粒機(畑鉄工所、HU−G型)に移し、押し出し羽根回転速度17rpmの稼動条件で0.5mmφの孔より押し出した。これを通風乾燥機中において40℃で17時間乾燥後、500μm篩を通過させて整粒し、日局細粒の粒度規格を満足する造粒物を得た。
フマル酸クエチアピン230.26g、乳糖細末141.74g、ヒドロキシプロピルセルロース8g、結晶セルロース20gを秤取して混合後、50vol%エタノール100mLを添加し、比較例1と同様にして日局細粒の粒度規格を満足する造粒物を製造した。
フマル酸クエチアピン230.26g、乳糖細末121.74g、ヒドロキシプロピルセルロース8g、結晶セルロース40gを秤取して混合後、50vol%エタノール110mLを添加し、比較例1と同様にして日局細粒の粒度規格を満足する造粒物を製造した。
フマル酸クエチアピン230.26g、乳糖細末81.74g、ヒドロキシプロピルセルロース8g、結晶セルロース80gを秤取して混合後、50vol%エタノール130mLを添加し、比較例1と同様にして日局細粒の粒度規格を満足する造粒物を製造した。
比較例1で得られた造粒物(以下、「造粒物A」という)および実施例1から3で得られた造粒物(以下、それぞれ「造粒物1」、「造粒物2」および「造粒物3」という)を用い、それぞれの製剤におけるフマル酸クエチアピン(以下主薬という)の溶出率を比較した。試験は主薬の25mg相当量を含む造粒物を、それぞれ37℃に加温した日本薬局方第二液900mL中に添加し、パドル回転数50rpmで撹拌して経時的に主薬の濃度を測定することにより行った。その結果を図1に示す。図1から明らかなように、結晶セルロースにより主薬の溶出性は改善され、結晶セルロースの含有量により主薬の溶出性を調整することができた。

実施例4から6で得られた造粒物(以下、それぞれ「造粒物4」、「造粒物5」および「造粒物6」という)を用い、それぞれの製剤におけるフマル酸クエチアピン(以下主薬という)の溶出率を比較した。試験は主薬の25mg相当量を含む造粒物を、それぞれ37℃に加温した日本薬局方第二液900mL中に添加し、パドル回転数50rpmで撹拌して経時的に主薬の濃度を測定することにより行った。その結果を図2に示す。図2から明らかなように、ラウリル硫酸ナトリウムの配合量により主薬の溶出性を調整することができた。
フマル酸クエチアピン345.39g、乳糖細末498.81g、ヒドロキシプロピルセルロース20g、結晶セルロース50g、部分α化デンプン50g、アスパルテーム35gを秤取して混合後、ラウリル硫酸ナトリウム0.3gを溶解した50vol%エタノール290mLを添加し、比較例1と同様にして製粒した。さらにこの粒900gに含水二酸化珪素0.45gを混合し、日局細粒の粒度規格を満足する造粒物を得た。
