Physicochemical Performances of Indomethacin in Cholesteryl Cetyl Carbonate Liquid Crystal as a Transdermal Dosage
2012
A transdermal formulation of indomethacin (IMC) was developed by incorporation into cholesteryl cetyl carbonate (CCC). The liquid crystalline phase properties of the IMC–CCC mixture were detected by polarized light microscopy and differential scanning calorimetry. A low drug loading was obtained (1–5 %) similar to that used in conventional topical IMC in a clinical setting. A controlled release of IMC was found over 12 h. A low amount of IMC in 1 % IMC–CCC permeated the stratum corneum. Further formulation development has been carried out by the addition of lauryl alcohol into 5 % IMC–CCC mixture it was found that the permeation of IMC was significantly improved to 45 % within 24 h.
