A pharmaceutical preparation containing magnetic vesicular particles is disclosed, wherein the magnetic vesicular particles each include magnetic microparticles within a lipid membrane, an organic compound having at least two groups selected from the group consisting of a hydroxyl group, a carboxyl group, a carbamoyl group, an amino group, a mercapto group, a sulfo group, a dithio group, a thiocarboxyl group and a dithiocarboxyl group is bonded to the magnetic microparticle, and the magnetic vesicular particles satisfy the following equation:
0.05≦
R
/(
r
×100)≦1.5
wherein R represents an average grain size of the magnetic vesicular particles and r represents an average particle size of magnetic microparticles included in the magnetic vesicular particles.
本发明涉及一种含有磁性囊泡颗粒的制剂,其中磁性囊泡颗粒包括磁性微粒在脂质膜内,有机化合物与磁性微粒键合,该有机化合物至少具有羟基、羧基、氨基、硫醇基、磺酸基、二硫基、硫代羧酸基和二硫代羧酸基中的两种基团。磁性囊泡颗粒满足以下方程式:0.05≦R/(r×100)≦1.5,其中R表示磁性囊泡颗粒的平均粒径,r表示磁性微粒的平均粒径。
