Abstract
Pseudoephedrine (substituted phenethylamine) is well known as psychotic and bronchodilator. Numerous studies on phenethylamine derivatives indicated that these agents have the potential to abolish inflammatory responses in the non-biological and biological systems. These facts provided the basis to conduct a study on pseudoephedrine to explore its therapeutics in Complete Freund’s Adjuvant (CFA)-induced arthritis. Furthermore, existing treatment approaches for RA associated with limited effect on chronic immunological models. Real-time polymerase chain reaction (q-PCR) was performed to execute the expression of pro and anti-inflammatory cytokines in treated and non-treated arthritic rats. These findings were further co investigate by histological observations. The paw volume, paw diameter, weight variations and arthritic score were determined at specific days throughout the experiment of 28 days. Pseudoephedrine at all doses significantly (p < 0.001) suppressed the expression of PGE2, TNF-α, IL-1β and IL-6. Moreover, pseudoephedrine (20 and 40 mg/kg) caused significant augmentation of IL-4 and IL-10. Similarly, the drug expressed a significant anti-arthritic effect by reducing the paw volume, paw diameter and arthritic score. Similarly, it also reverts the reduction in body weight of arthritic rats at all above-mentioned doses. These findings supported the anti-arthritic potential of pseudoephedrine and recommended it for clinical trials.
