FORMULATION AND EVALUATION OF NANOSTRUCTURED LIPID CARRIER FOR THE MANAGEMENT OF PSORIASIS

The objective of the research work was to design NLCs gel of Acitretin and perform an in-vitro evaluation of different formulations. FTIR and DSC studies revealed that there was no interaction between drug and polymer and with the respective surfactant. A new generation of NLCs consisting of a lipid matrix with a special nanostructure has been developed. These nanostructures improve drug loading and firmly incorporates the drug during storage. The purpose of this study was to prepare Acitretin-loaded NLCs gel effective for topical delivery of Acitretin by using the Hot Homogenization method. Stearic acid as solid lipid, Oleic acid as liquid lipid combination of two types of surfactant: Tween 80 and Sodium lauryl sulphate (SLS) were used to stabilize NLCs dispersion. Physiochemical properties of NLCs gel such as particle size, TEM, entrapment efficiency, and in-vitro release studies were investigated. The formulation in which a combination of ionic and non-ionic surfactant was used to demonstrated good entrapment efficiency, sustained in-vitro release profile. In-vitro release study revealed the biphasic release pattern of NLCs gel system. Results suggested that the combination of two surfactants produces a stable system with good entrapment efficiency and desired particle size. Act NLCs gel formulation with skin targeting may be a promising carrier for topical delivery Acitretin.
