    • Dermal Application of Chloramphenicol - The Effect of Liposomes and Chitosan Hydrogel Formulations on ex vivo Permeation and Antimicrobial Activity 

      Holsæter, Ann Mari; Ingebrigtsen, Sveinung Gaarden; Skalko-Basnet, Natasa (Conference object; Konferansebidrag, 2017)
      Liposomes solubilize lipophilic drugs in the phospholipid membrane, and entrap hydrophilic drugs in its aqueous core. These vesicles provide a sustained- and targeted- drug release, and protect from degradation. Liposomes retain the drug onto/in the skin and improve skin drug deposition. Due to their liquid nature, a secondary vehicle, such as a hydrogel, is needed to obtain a necessary retention ...
