Resumo

Rheumatoid arthritis (RA) is an autoimmune disease that causes joint degeneration and leads to loss of function in the area. One of the drugs associated with its treatment is leflunomide, a drug that belongs to the isoxazole class and inhibits the enzyme dihydroorotate dehydrogenase. However, it has adverse events that can make its use unfeasible. Thus, topical administration is a promising alternative and for this, the development of nanoformulations is an option. Lipid nanosystems have the advantage of accommodating the drug in their structure and can be developed by different methods. The objective of this work was to evaluate the influence of preparation methods and composition of nanostructured lipid carriers (NCL). Emulsification and solvent evaporation and emulsification melting methods were used, associated with the use of a microfluidizer or sonicator. Parameters were evaluated in relation to size and polydispersity index (PDI), by DLS method, and stability for 7 days was evaluated. The average size of 163.4 nm was obtained, with a PDI of 0.301, but there was a tendency for these parameters to increase during stability, being significant after four days, which may be associated with the nanocarrier formulation. More studies should be carried out in order to optimize production and formulation parameters.
