Abstract
Description
本願は、2013年4月23日出願の米国仮特許出願第61/815,073号、及び、2013年9月20日出願の米国仮特許出願第61/880,294号に基づく優先権を主張するものであり、参照により全内容を本願に援用する。
この項は、本発明の多微粒子組成物及び方法の態様の具体的な例を提供する。これらの例は、本発明の特定の好ましい態様及び実施形態を例示するために提供されるが、本発明の範囲は、これらの実施例が教示するものに限定されない。
AVICEL(登録商標)PH 102(FMC Corp.,Philadelphia,PA)という名で市販の結晶セルロース(MCC)、METHOCEL(登録商標)A15LV(Dow Chemical Co.,Midland,MI)という名で市販のメチルセルロース、蒸留されたハッカ油、及び、USP精製水を使用してコアを調製した。
ゼラチンサブコーティングは、長期間にわたって上昇した温度にて保管された場合にハッカ油が蒸発し、さらに、コアをそのままにするのを防ぐということを確実にするために、実施例1において記載した多微粒子組成物を後に試験した。
