DMARDs

Disease-modifying antirheumatic drugs (DMARDs) are crucial in treating rheumatoid and psoriatic arthritis. Methotrexate, a folic acid antagonist, is commonly used due to its immunosuppressive and anti-inflammatory properties, though it can cause side effects like liver cirrhosis and mucosal ulceration.

DISEASE-MODIFYING ANTIRHEUMATIC DRUGS (DMARDs)

3-BIOLOGIC THERAPIES IN RHEUMATOID ARTHRITIS

Anakinra
IL-1 receptor antagonist
Tofacitinib
METABOLISUM by CYP3A4
inhibitor of Janus kinases
Tocilizumab
blocking the IL-6 receptor
Rituximab
B-cell depletion
Abatacept
preventing full T-cell activation
Adalimumab, Certolizumab, Etanercept, Golimumab, Infliximab
Infliximab is not indicated for monotherapy
moderate to severe RA, psoriatic arthritis, ankylosing spondylitis, and Crohn's disease
They interfere with the binding of TNF- α to its receptor
IL-1 and TNF- α are pro-inflammatory cytokines involved in the pathogenesis of RA

1-Choice of drug

Most of these agents are contraindicated for use in pregnant women.
For patients with more established disease, use of other biologic therapies is considered
Monotherapy may be initiated with any of the DMARDs
sulfasalazine
hydroxychloroquine
leflunomide
methotrexate
A trial of several different drugs may be necessary
No one DMARD is efficacious and safe in every patient
