title: Influence of tensides on the release of medical agents from hydrophilic gels, part 2: The influence of selected tensides on hydrocortisone release from xerogels.
abstract: With the increase of polysorbates 20 and 21 concentration in xerogels, in the presence of 1,2-propylene glycol and PEG 200, hydrocortisone half-release periods from these preparations become longer while the half-release periods for polysorbate 80 and propylene glycol, and polysorbate 21 and PEG 200 are proportionally shortened. The concentration of tensides has no significant impact on the half-release periods of hydrocortisone with polysorbate 81 added to xerogels in the presence of propylene glycol and polysorbate 20 and 80 with PEG 200.
