タルクおよび酸化チタンを少量の精製水に分散させた後、エタノール、クエン酸トリエチル、およびヒプロメロース酢酸エステルコハク酸エステルを添加して第3の懸濁液を得た。次いで、上記と同様の転動流動層コーティング機内でこの第3の懸濁液を第2の薬剤粒子にスプレーして、第2の薬剤粒子を腸溶層で被覆した腸溶性粒子を得た。
低置換度ヒドロキシプロピルセルロース(信越化学工業(株)製L-HPC(登録商標)LH-31;ヒドロキシプロポキシ基含量11%、平均粒子径20μm)を少量の精製水に分散させた後、80℃に加温した精製水に溶解させたポリビニルアルコール(三菱ケミカル(株)製ゴーセノールEG-03P;けん化度86.5~89.0モル%(部分けん化物))を添加して、第4の懸濁液を得た。次いで、上記と同様の転動流動層コーティング機内で、この第4の懸濁液を腸溶性粒子に対してスプレーして、腸溶性粒子を被覆層で被覆した被覆粒子を得た。
被覆粒子に、D-マンニトール、結晶セルロース、クロスポビドン、スクラロース、軽質無水ケイ酸、l-メントール、およびフマル酸ステアリルナトリウムを添加かつ混合して、打錠用顆粒を得た。その後、この打錠用顆粒を単発打錠機内で圧縮成形して、錠剤(E1)(重量400.4mg、錠剤径9.5mm、錠剤厚み5.2mmおよび硬度65N)を得た。
錠剤の被覆層に含まれる低置換度ヒドロキシプロピルセルロースの含有量を12.8mg(2倍)、当該被覆層に含まれるポリビニルアルコールの含有量を0.4mg(2倍)に変更し、かつ打錠の際、被覆粒子とともに添加したD-マンニトールの含有量を131.6mgに変更したこと以外は、実施例1と同様にして錠剤(E2)(重量400.4mg、錠剤径9.5mm、錠剤厚み5.2mmおよび硬度65N)を得た。
錠剤の被覆層に含まれる低置換度ヒドロキシプロピルセルロースの含有量を17.92mg(2.8倍)、当該被覆層に含まれるポリビニルアルコールの含有量を0.56mg(2.8倍)に変更し、かつ打錠の際、被覆粒子とともに添加したD-マンニトールの含有量を126.3mgに変更したこと以外は、実施例1と同様にして錠剤(E3)(重量400.4mg、錠剤径9.5mm、錠剤厚み5.2mmおよび硬度65N)を得た。
腸溶性粒子に被覆層を設けなかったこと(すなわち、被覆粒子の代わりに腸溶性粒子を用いたこと)、および打錠の際、被覆粒子とともに添加したD-マンニトールの含有量を144.8mgに変更したこと以外は、実施例1と同様にして錠剤(C1)を得た。
実施例1~3および比較例1で得られた錠剤(E1)~(E3)および(C1)について、日本薬局方溶出試験法第2法(パドル法)によるデュロキセチンの溶出性試験を行った。試験液として溶出試験液第2液(pH6.8)900mLを用い、それぞれパドル回転数75rpmにて、120分間の溶出率(%)の経時変化を所定の時間毎に測定した。得られた結果を図2に示す。
錠剤に含まれる低置換度ヒドロキシプロピルセルロースの含有量を17.0mgに変更し、結合剤(ポリビニルアルコール)の含有量を0.5mgに変更し、かつ打錠の際、被覆粒子とともに添加したD-マンニトールの含有量を127.3mgに変更したこと以外は、実施例1と同様にして錠剤(E4)(重量400.4mg、錠剤径9.5mm、錠剤厚み5.2mmおよび硬度65N)を作製した。
