A summary of the article is shown below:
In this research, MIL-53(Fe) was magnetized and the performance of the magnetized material as a drug delivery system for doxycycline was studied. The experiments were designed to load the magnetic delivery compounds with different amount of the drug. The In vitro release rate of doxycycline from magnetic MIL-53(Fe) with different drug content into saline buffered fluid (SBF, pH=7.4) and phosphate buffered saline (PBS, pH=3) was then studied. The results showed that the releasing process of the drug in PBS media achieve to the equilibration within 48h with 98% of releasing efficiency, while the releasing process in SBF media (pH=7.4) was slower and the equilibrium was established within 264 h with releasing efficiency of 95%. The amount of the released doxycycline from the samples with different drug content was measured for various time interval. It was concluded that in PBS media after 75 h, 85, 95 and 98% of loaded doxycycline was released respectively from the sample containing 22, 32 and 35% of the drug. In SBF media the release was slower and after 350 h, 82, 91 and 95% of loaded doxycycline was released from the samples respectively containing 22, 32 and 35 % of the drug. The results of this study indicated that by use of drug releasing profile and selecting appropriate carrier dose, the released amount of the drug into the patient body can be controlled.
