組成物を当業者に知られている技術によって原液として処方することができる。組成物が固体として処方される場合は、顆粒剤の剛性を向上させるためにアタクレーなどの増量剤を添加することができる。

BPOのシリカコーティング
工程1:粉砕:110gの含水BPO75%(SigmaのUSPグレード)を、0.001%の珪素消泡剤を含有する152gの0.4%CTAC溶液に懸濁させた。固定ロータミキサー(15000rpm/25m/sで動作するKinematikaポリトロン6100)を使用して、BPOを粉砕した。懸濁液の粒径分布(PSD)がd(0.9)<35μmになったとき、又は温度が50℃に達したときに粉砕を停止した。最終的な懸濁液を室温まで冷却した。
BPO放出の分析評価:
シリカ殻からのBPOの放出プロファイルを、BPOを溶解することが可能な水/アセトニトリル溶液中で実施した。方法は、BPOの強い酸化性に基づく。BPOは、ヨウ化カリウム(KI)イオンと反応して、呈色反応を与えるI2を形成する。次いで、チオ硫酸ナトリウム(STS)を使用してI2をI−に還元して、色を除去する。それぞれ12.11mgの酸化性BPOを1mlの0.1MのSTSによって還元した。
カプセル化(コーティング)サイクル毎のシリカ添加量が多いほど、且つ/又はコーティングサイクルの数が多いほど、BPO放出の時間が長くなることが明確にわかる。
トレチノイン(ATRA)のシリカコーティング
工程1:粉砕:75gの全トランスレチノイン酸(ATRA)(RhodiaのUSPグレード)を、0.001%の珪素消泡剤を含む250gの0.3%CTAC溶液に懸濁させる。M−110Yマイクロフルイダイザー処理装置(Microfluidics)を使用してATRAを15000psiで粉砕する。懸濁液の粒径分布(PSD)がd(0.9)<20μmになったときに粉砕を停止する。温度を常に30℃未満に維持する。
アニオン性界面活性剤を使用したシリカコーティング
工程1:粉砕:110gの含水BPO75%(SigmaのUSPグレード)を、0.005%の珪素消泡剤を含有する152gの0.4%ドデシルスルホン酸ナトリウム(SDS)溶液に懸濁させた。固定ロータミキサー(15000rpm/25m/sで動作するKinematikaポリトロン6100)を使用して、BPOを粉砕した。懸濁液の粒径分布(PSD)がd(0.9)<35μmになったとき、又は温度が50℃に達したときに粉砕を停止した。最終的な懸濁液を室温まで冷却し、1〜2.5gの分量の3%ポリクオタニウム7を添加し、懸濁液を5分間撹拌した。
非イオン性ポリマーを使用したトレチノイン(ATRA)のシリカコーティング
工程1:粉砕:12.5gのトレチノインを、7.5gのBHTを含む250gの0.3%CTAC溶液に懸濁させた。トレチノインを、M−110Yマイクロフルイダイザー処理装置(Microfluidics)を使用して15000psiで粉砕した。懸濁液の粒径分布(PSD)がd(0.9)<13μmになったときに粉砕を停止した。温度を常に30℃未満に維持する。
カチオン性ポリマーを使用したビフェントリンのシリカコーティング
3.58グラムの塩化セチルトリメチルアンモニウム(CTAC)(29%w/w水溶液)を1リットルフラスコ内の196.5グラムの脱イオン水に添加した。50.5グラムの乾燥粉砕された工業用ビフェントリン(平均粒径が約15ミクロン)を添加し、ポリトロンPT6100ホモジナイザを使用して混合物を均質化した。216グラムの得られた分散物をメトラトレドLabMax自動ラボリアクタに移した。
非イオン性ポリマーを使用したビフェントリンのシリカコーティング
2.1グラムのCTAC(29%w/w水溶液)を1リットルフラスコ内の125グラムの脱イオン水に添加した。(0.5%w/wのCTACをも含む)125グラムのビフェントリンの20%w/w水性分散物を添加した。ポリトロンPT6100ホモジナイザを使用して混合物を均質化し、得られた分散物をメトラトレドLabMax自動ラボリアクタに移した。
共重合体を使用したビフェントリンのシリカコーティング
2.1グラムのCTAC(29%w/w水溶液)を1リットルフラスコ内の125グラムの脱イオン水に添加した。(0.5%のCTACをも含む)125グラムのビフェントリンの20%w/w水性分散物を添加した。ポリトロンPT6100ホモジナイザを使用して混合物を均質化した。さらなる75グラムの脱イオン水を添加し、得られた分散物をメトラトレドLabMax自動ラボリアクタに移した。
米国特許第6,303,149号に開示されている種類のゾル−ゲル法を採用し、塩化セチルトリメチルアンモニウムを含む水相並びにテトラエトキシシラン(TEOS)及び工業用ビフェントリンを芳香族有機溶媒に含む有機相を採用してビフェントリンのコア/殻組成物を製造した。該組成物は、8.4%w/wの96%工業用ビフェントリンを含んでいた。
