Corticosteroid release from solid affinity polymers (β-CD, blue; γ-CD,green) and non-affinity control polymer (Dextran, gray). Dextran shows classic diffusion based burst in the first three days of release for all corticosteroids. Affinity polymers showed a slower release which validates its further exploration as potential candidates for formulation as an injectable liquid polymer for the intra-articular cavity of corticosteroids.
