Sulfasalazine is a combination of an aspirin like anti-inflammatory component and a sulfa antibiotic like component. It is an Anti-inflammatory agent used to relive the pain of the Bowel diseases, Rheumatoid arthritis, Psoriatic arthritis, Crohn’s disease and Ulcerative colitis. Sulfasalazine acts to deplete the damage to the joints, rather than just relieve the pain, it belongs to the group of medicines called disease modifying anti-rheumatic drugs (DMARDs). Methodology: The objective of the present study is to prepare, optimize the nanoparticles containing sulfasalazine and bovine serum albumin (BSA) by using desolvation method, and to study the effect of process variables like stirring speed on product yield, drug content. Glutaraldehyde is used as crosslinking agent and sulfasalazine is used as model drug. Results: The prepared nanoparticles showed maximum drug content, for continuous method-97.27% and for intermittent method-95.08%. The prepared nanoparticles showed good product yield of 96.26% (intermittent method) and 98.4% (continuous method). Invitro release of sulfasalazine loaded nanoparticles showed good sustained release and maximum drug release of 38.05% for continuous method and 40.73% for intermittent method within 6 hours interval.
