Potentially Fatal: Hepatotoxicity, sepsis, Stevens-Johnson syndrome, toxic epidermal necrolysis, pancreatitis.

Drug Interactions

Cholestyramine and activated charcoal may decrease plasma concentration of active metabolite. Concurrent use of methotrexate and other hepatotoxic drugs may increase the risk of hepatotoxicity. Rifampicin increases serum levels of the active metabolite. Potentially Fatal: May enhance the adverse effects of live vaccines.

Contraindications

Hepatic impairment, moderate and severe renal impairment, compromised immune function including bone marrow dysplasia or severe uncontrolled infection, severe hypoproteinaemia; concurrent vaccination w/ live vaccines. Pregnancy and lactation.

Mechanism of Action

Leflunomide is an immunomodulating agent and DMARD. It inhibits pyrimidine synthesis by inhibiting dihydroorotate dehydrogenase enzyme activity resulting in antiproliferative and anti-inflammatory effects. Absorption: Bioavailability: Approx 82-95%. Time to peak plasma concentration (active metabolite): 6-12 hr. Distribution: Volume of distribution: 0.13 L/kg. Plasma protein binding (active metabolite): 99% (mainly albumin). Metabolism: Rapidly converted to active metabolite A77 1726 in GI mucosa and the liver. Excretion: Via urine (approx 43% as glucuronides) and faeces (approx 48%). Elimination half-life (active metabolite): Approx 14-18 days.
