ABSTRACT

Oral conventional formulations like tablets, capsules and liquids have many limitations. Due to this and patient incompliance, there is a need to develop new formulations with better efficiency and stability. The aim of the present study was to develop and optimize fast dissolving Oro-dispersible strips (ODS) of isosorbide mononitrate by 3² -full factorial design. HPMC E15 (X₁ ) concentration and glycerin (X₂ ) concentration were selected as the independent variables, whereas, in vitro disintegration time (Y₁ ), percent drug release (Y₂ ) and tensile strength (Y3 ) were selected as dependent variables. Fast dissolving Oro-dispersible strips of isosorbide mononitrate were prepared by the solvent casting method.Tensile strength, disintegration time and in vitro dissolution of ODS of the strip were found to be within accepted range for optimized formulation. Statistical validity of the polynomials was established by ANOVA using Design-Expert software. The study suggests isosorbide mononitrate fast dissolving Oro-dispersible strip as potential alternative dosage form in management of angina pectoris.
