In Vitro Drug Absorption Enhancement Effects of Aloe vera and Aloe ferox
AbstractThe effect of whole leaf and gel materials from two aloe species (Aloe vera and A. ferox) was compared with that of the precipitated polysaccharides from these aloe materials on the transepithelial electrical resistance (TEER) as well as transport of a model compound (atenolol) in the apical-to-basolateral direction across rat intestinal tissue. All the aloe leaf materials and precipitated polysaccharides had a statistically significant effect of lowering the TEER (P < 0.05) compared to the control group, which indicates their ability to open tight junctions between adjacent epithelial cells. In contrast to the expectation from the TEER results, only the precipitated polysaccharides from dehydrated A. vera gel (Daltonmax 700®) had a statistically significant effect of enhancing the transport of atenolol (P < 0.05). These in vitro results therefore indicate that A. vera gel polysaccharides have potential as drug absorption enhancing agents in novel pharmaceutical drug delivery systems.
