FORMULATION AND ASSESSMENT OF SEMI-SOLID CARRIER INCORPORATED WITH HERBAL EXTRACT OF LAWSONIA INERMIS. | LitMetric

AI Article Synopsis

Article Abstract

The development of an optimal microemulsion of lawsone for transdermal delivery was the core objective of the study. Effects of formulation variable including oils, surfactants and co-surfactants on the per- cutaneous delivery of lawsone microemulsion have also been inspected. Pseudotemary phase diagrams with oil, cosurfactant-surfactant mixtures (Smix) were constructed to recognize the microemulsion areas. Microemulsion prepared was of 5%. The in vitro transdermal penetration of microemulsion of lawsone was determined by Franz diffusion cell. These profiles indicated that the absorption and rate of penetration of lawsone microemul- sion was far better than the saturated solution of lawsone. The formulation was characterized for pH, conduc- tivity, viscosity and passed stability tests. A non-irritant formulation to skin was prepared in this way. The out- comes specify that the transdermal drug delivery ability and phase behavior of microemulsion is affected by the type of cosurfactant and surfactant.
