Abstract
Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease, progressively distinctive
via cartilage destruction, auto-antibody production, severe joint pain, and synovial inflammation.
Nanotechnology represents as one of the utmost promising scientific technologies of the 21st century.
It exhibits remarkable potential in the field of medicine, including imaging techniques and diagnostic
tools, drug delivery systems and providing advances in treatment of several diseases with nanosized
structures (less than 100 nm).
Objective: Conventional drugs as a cornerstone of RA management including disease-modifying antirheumatic
drugs (DMARDS), Glucocorticosteroids, etc are under clinical practice. Nevertheless, their
low solubility profile, poor pharmacokinetics behaviour, and non-targeted distribution not only hamper
their effectiveness, but also give rise to severe adverse effects which leads to the need for the emergence
of nanoscale drug delivery systems.
Methods: Several types of nano-diagnostic agents and nanocarriers have been identified; including polymeric
nanoparticles (NPs), liposomes, nanogels, metallic NPs, nanofibres, carbon nanotubes, nano
fullerene etc. Various patents and clinical trial data have been reported in relevance to RA treatment.
Results: Nanocarriers, unlike standard medications, encapsulate molecules with high drug loading efficacy
and avoid drug leakage and burst release before reaching the inflamed sites. Because of its enhanced
targeting specificity with the ability to solubilise hydrophobic drugs, it acts as an enhanced drug
delivery system.
Conclusion: This study explores nanoparticles potential role in RA as a carrier for site-specific delivery
and its promising strategies to overcome the drawbacks. Hence, it concludes that nanomedicine is advantageous
compared with conventional therapy to enhanced futuristic approach.
