The present paper focused on the intercalation of ibuprofen into Unmodified sodium  montmorillonite, chitosan and chitosan montmorillonite nanocomposites as a sustained release drug carrier. The intercalation compounds were characterized by X-ray diffraction (XRD), Infrared spectroscopy (IR), Thermogravimetric analysis (TGA), and transmission electron microscopy (TEM). The basal spacing of montmorillonite increased from 9.6 nm to 19.6 nm as indicate of intercalation of modified chitosan and ibuprofen between lamellar layers. UV spectroscopy was employed to monitor the in vitro drug release processes in both pH 5.4 and 7.8 solutions. And the experiment  revealed that Ibuprofen was released from MMT, CS and Mod-CS/MMT  steadily and pH dependent.
