)orthogonal design was used to obtain optimal formulation.The micromeritic properties and in vitro dissolution of the pellets were determined. Results Isosorbide mononitrate pellets prepared by extrusion/spheronization were all spheral and smooth.In vitro dissolution was more than 95%. Conclusion The quality of pellets is excellent. The preparation process is simple and suitable for the industrial production.
