Humic substances as active or auxiliary pharmaceutical component
 Blahuš, Petr ; Kalina, Michal (referee) ; Sedláček, Petr (advisor)
This thesis examines the effect of the potassium lignohumate on the transfer speeds of analgesic drugs through the synthetic Strat-M® membrane. In order to examine the transfer of these substances, vertical diffusion cells were used and the final samples were analysed using UV-VIS spectrometer and HLPC. The intention of this thesis was to optimise the process of preparing diffusion cells, to compare the transfer speeds of pure active substances and active substances with the potassium lignohumate, and to compare the permeability of Strat-M® membranes, by using pig skin membranes which were used in the previous study that this thesis continues from. The primary discovery was that the lignohumate slowed down the transfer of active substances through the membrane.
