Leflunomide nanocarriers: a new prospect of therapeutic applications.

AbstractLeflunomide (LEF) is a well-known disease-modifying anti-rheumatic agent (DMARDs) that was approved in 1998 for rheumatoid arthritis (RA) management. It is enzymatically converted into active metabolite teriflunomide (TER) inside the body. LEF and TER possess several pharmacological effects in a variety of diseases including multiple sclerosis, cancer, viral infections and neurobehavioral brain disorders. Despite the aforementioned pharmacological effects exploring these effects in nanomedicine applications has been focused mainly on RA and cancer treatment. This review summarises the main pharmacological, and pharmacokinetic effects of LEF along with highlighting the applications of nanoencapsulation of LEF and its metabolite in different diseases.
