Sodium alginate–poly(vinyl pyrrolidone) pH-responsive hydrogels for controlled release of tinidazole

Key Points

• The aim is to investigate the properties of sodium alginate/poly(vinyl pyrrolidone) hydrogels for drug delivery.
• Developed cross-linked hydrogels using sodium alginate and poly(vinyl pyrrolidone)
• Tested pH-responsiveness of the hydrogels
• Evaluated structural integrity compared to conventional hydrogels
• Cross-linked hydrogels showed enhanced structural integrity
• The hydrogels are responsive to changes in pH
• Evidence suggests effective controlled release of tinidazole at specific pH levels
