Stability studies of Hollow Microspheres at Refrigerated, Normal and Accelerated Conditions

Abstract

In the present investigation an attempt was made to focus on the stability aspects of itraconazole hollow microsphere at refrigerated condition, room temperature and at accelerated condition. In stability studies, more emphasis given on the effect of different temperature conditions on appearance, % drug content, % buoyancy and % drug release of formulation over a period of 6 months. Apart from above studies, SEM and FTIR analysis was done to determine any change in morphology or chemical structure. The results showed non-significant changes in pharmaceutical properties. From result findings, it can be concluded that the itraconazole hollow microspheres are stable formulation to sustain the drug in upper GIT for prolonged period of time.
