In vitro release kinetics at 37°C for 17-DMAPG loaded into liposomes (passive/active methods) and lipogels (active method) at pH 7.4 and 5.0. There was no significant release difference at pH 7.4 and 5.0 within the liposome (passive/active-loaded) or lipogel (active-loaded) formulations (p>0.05), confirming that release kinetics were pH-independent. However, there were significant release differences between the formulations at pH 7.4 and 5.0 for all time points >6 h (p<0.01); passive-loaded liposomes exhibited the fastest release (ca. 1.5 h to 50% release), active-loaded liposomes exhibited moderate sustained release (ca. 16 h to 50% release), and lipogels exhibited the slowest sustained release (ca. 54 h to 50% release). The data reported are mean ± SD of triplicates.
