Abstract

The objective of this study was to design a simple, colon targeted drug delivery system by using porous starch (PS), pectin and chitosan. Porous maize starch was prepared by hydrolysis with a combination of α-amylase and amyloglucosidase, and it was characterized by scanning electron microscopy, revealing the formation of porous structures in the starch granules. A Brunauer-Emmett-Teller (BET) specific surface area analysis indicated that the specific surface area of the PS (0.8768–0.9448 m2/g) was 19.88–21.42 times larger than that of native maize starch (0.0441 m2/g). The average pore diameter of the PS granules, as calculated by the Barrett-Joiner-Halenda (BJH) method, was 40.52–62.42 nm. A favorable adsorptive potential of the PS granules was verified by water and soybean oil tests. Doxorubicin was loaded into PS granules, which were then coated with a pectin/chitosan complex solution. The results of confocal laser scanning microscopy (CLSM) demonstrated that doxorubicin was successfully absorbed into the PS granules. In addition, an in vitro simulated digestion method demonstrated the effectiveness of this delivery design, as only a 13.80% release rate of doxorubicin was observed in the upper gastrointestinal tract, whereas release rates of 17.56% and 67.04% were observed for pectin/PS/doxorubicin and pectin/doxorubicin beads, respectively. It was concluded that the use of PS and a pectin/chitosan coating is an effective method for colon targeted drug delivery compared w…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
