Some Variables Affecting the Formulation of Pentoxifylline (PTX) as a Solid Sustained Release Dosage Form
An inert matrix that is used to control the release of (PTX) was prepared using Eudragit RL100 and RSPM types Immune Support as matrix forming agent.The matrices were prepared by either dry granulation(slugging) , or wet granulation method using chloroform as a solvent evaporation vehichle.The cumulative release was adjusted by using polyvinylpyrol
