From: Release characteristics of enoxaparin sodium-loaded polymethylmethacrylate bone cement
Enoxaparin sodium is a mucopolysaccharide substance with a relative molecular weight (Mr) of 3500–5500 with good water solubility. With the increase amount of ES added in PMMA bone cement, the pores between the polymers were filled and the gaps between beads became shallow. Some sugar-like substances were also observed under the SEM. Therefore, ES-PMMA bone cement is considered as a carrier which can release enoxaparin sodium.
