[Influence of excipients on caffeine permeation from gels].

Unlabelled: The subject of this paper is a study of the influence of excipients on caffeine permeation from dermal semisolids drugs. Due to its advantageous properties, caffeine can be successfully used in dermal hydrogels. The choice of excipients from the group of humectants and cationic surfactants also plays an important role.
