The main aim of the research work was the formulation and evaluation of controlled release microspheres loaded with methotrexate
drug. Literature review showed that suspensions of degradable microspheres can be employed for sustained drug release at desirable
doses. They used as carriers for anticancer drugs. These spheres manufactured in micron size. For this preparation used ethyl cellulose
and other excipients. Hence it was investigated and microspheres were prepared with anticancer drug like methotrexate. These are
tested furthermore with scanning electron microscopy studies, Fourier transform infra red spectroscopy studies and dissolution studies.
