Description
本明細書および添付の請求の範囲を通じて、「噴射/粉砕媒体」という用語をエアゾル製剤処方の固体治療薬および付加固体成分の液体粉砕のための粉砕工程に使用され、エアゾル製剤処方中に残留して最終的に噴射剤の機能をする物質を表すのに使用する。
C以下の沸点を有する物質である。
Cから約10°
Cの温度範囲である。この冷却は粉砕中の混合液を冷して熱によって劣化しやすい治療薬を保護する利益もある。本発明の工程の好ましい実施例においては、噴射/粉砕媒体の混合物を、交互に供給タンクと受容タンクとなり、両方とも二重壁でタンクの壁の間の冷却ジャケットあるいはタンク内部の冷却コイルを通して冷却剤を流す装備のある二つのタンク間の粉砕器中を連続的に通過させることによってこれが成就される。
Claims (6)
- (a)エアゾル製剤処方の固体成分を液体噴射剤と混合し、(b)段階(a)で形成された混合物を、混合物に含まれる固体の粒度が所定の最大値に減少するまで、第一冷却供給タンクと第二冷却受容タンク間を粉砕器を介して繰り返し通過させ、(c)固体成分と液体噴射剤との粉砕混合物をエアゾル缶に充填することを含む、固体成分を含むエアゾル製剤処方の調製方法。
- 前記噴射剤が、低沸点低級アルカン類、低沸点ハロゲン化低級アルカン類、低沸点低級シクロアルカン類、低沸点ハロゲン化低級シクロアルカン類、低沸点ジ(低級アルキル)エーテル類、低沸点ハロゲン化ジ(低級アルキル)エーテル類、低沸点ジ(低級アルキル)チオエーテル類および低沸点ハロゲン化ジ(低級アルキル)チオエーテル類からなる群から選択される請求の範囲第1項に記載の方法。
- 前記噴射剤が、クロロジフルオロメタン、クロロトリフルオロメタン、ジクロロジフルオロメタン、トリクロロフルオロメタン、テトラフルオロエタン、1、2―ジクロロテトラフルオロエタン、トリクロロフルオロエタン、クロロペンタフルオロプロパン、クロロヘプタフルオロプロパン、ヘプタフルオロプロパン、パーフルオロシクロプロパン、パーフルオロプロパン、パーフルオロ―n―ブタン、パーフルオロイソブタン、パーフルオロシクロブタン、パーフルオロジメチルエーテル、パーフルオロフラン、パーフルオロメチルアミン、bis―(トリフルオロメチル)スルフォン、bis―(トリフルオロメチル)スルフィドおよびトリフルオロメチルペンタフルオロスルフィドからなる群から選択される請求の範囲第1項に記載の方法。
- 前記噴射剤がテトラフルオロエタンである請求の範囲第1項に記載の方法。
- 前記噴射剤がヘプタフルオロプロパンである請求の範囲第1項に記載の方法。
- 固体の粒度が所定の最大値に減少したことを工程の流れを連続的に監視することによって決定する請求の範囲第1項に記載の方法。
