Abstract :

Rheumatoid arthritis (RA) is a very painful severe autoimmune disease with complex pathology characterized by progressive chronic inflammation, and devastation of the synovium, cartilage, and other joint-associated structures. Significant advances in research in the area of pathophysiology, diagnosis, drug development, and targeted delivery have led to improved RA therapy and better patient compliance. Targeted drug delivery using liposomal nanomedicines significantly alleviate the challenges with conventional anti-RA medications such as off-target effects, short biological half-life, poor bioavailability, high dose-related toxicity, etc. Liposomal nanomedicines in RA drug targeting offer the opportunity for passive targeting [based on size and polyethylene glycol (PEG)-ylation-mediated enhanced permeability and retention] and active targeting (ligation with antibody or peptides, etc.) and encapsulation of lipophilic, hydrophilic drugs, and/or combinational drugs. However, it has been found recently that such injectable nanomedicines raise the concern of an adverse immune phenomenon called complement activationrelated pseudo allergy (CARPA) and failure of therapy on multiple doses due to accelerated body clearance caused many by anti-PEG immunoglobulin M. To ensure safety and efficacy of RA therapy, these need to be considered along with the common formulation quality parameters. Here, we discuss nanotherapeutic targeting in RA therapy using liposomes. Liposomal nanoparticles are investigated for individual anti-RA drug categories. CARPA issues and pathophysiology with such nanomedicines are also discussed in detail.
