Assessment of Leflunomide Efficacy and Hepatotoxicity in Patients With Rheumatoid Arthritis Through Pharmacokinetic and Genetic Approaches

September 6, 2020 updated by: Alaa Abdelkhalik Ahmed Mohamed, Assiut University
The RA patients receiving leflunomide for more than one month, and not receiving other DMARDs (except hydroxychloroquine), will be enrolled to assess their disease activity. Blood samples will be collected for genetic studies and pharmacokinetic assay of the blood levels of the drug and its active metabolite.
