Abstract
The main goals of the invention are to develop the long-term release of Granisetron injection implant composition with biodegradable polymer and to develop relative processing. Granisetron is mixed with different biodegradable polymers, and then hot melt extrusion technique with different diameter, temperature, rate of extrusion and holding time is applied to make implant. In vitro dissolution of the Granisetron injection implant composition shows the component continued release of the drug for over 7 days.
