本発明者らは、ヤヌス微粒子の特徴を利用して、一方の半球は生体膜の反対側への薬物放出を抑えると同時に酵素に対するバリアとし、もう一方の半球は体温近くの温度で融解し、生体膜に接触すると吸収されるようにすることで、図1に示すシステムを考案した。本発明者らは創意検討の結果、ポリマーと脂質を適切な溶媒に溶解して油相を製造し、少量の水相に乳化し、徐々に液中乾燥して、その時間を制御することにより、目的の微粒子を製造できることを見出した。さらに、油相に、界面活性剤、不溶性の固体や水滴を加えて、Solid in oil(S/O) エマルションやWater in oil(W/O)エマルションを形成させ、水相に乳化させると、微粒子に固体や水滴を局在化させることができ、薬物層を形成できることを見出した。さらに、界面活性剤の種類と量により、微粒子中の薬物層の分布を制御できることを見出した。本発明の好ましい態様によれば、半球のみが温度により融解し吸収される球形微粒子を製造することができる。
