The invention discloses a strong acting force mediated intelligent
drug delivery system and a preparation method. The
system comprises a core-shell structure carrier matrix, a
drug active component, a'main acting force + auxiliary acting force 'strong acting force unit and a surface functional layer, the preparation method comprises the following steps: preparing a mesoporous core layer and a
polymer shell layer to form a core-shell carrier, mediating
drug loading through a strong acting force unit, and finally modifying a targeting ligand and PEG (
Polyethylene Glycol). The
system triggers'pulse-slow release 'dual-mode release of a drug through double physiological microenvironment stimulation, a strong acting force unit improves the load stability (the
leakage rate in 24 hours is smaller than or equal to 5%, and the encapsulation efficiency is larger than or equal to 75%), and targeting-anti-clearance modification enhances the targeting property (the
target site enrichment amount is larger than or equal to 30%) and the
circulation time (the half-life period is larger than or equal to 12 h). The preparation process is controllable, the
quality control is clear, the requirements of GMP (
good manufacturing practice) are met, the
drug effect can be improved, the toxic and side effects can be reduced, and the
traditional Chinese medicine composition is suitable for clinical transformation and industrialization.
