Design, formulation, optimization and stability studies of paracetamol effervescent tablets

Le résumé fourni par la source

The purpose of the current study was to develop stable effervescent-tablets without controlling area relativehumidity; temperature and no requirement of special packaging.Current 3 2 factorial-design experimental studies were conducted in the Research Laboratory of Pharmaceutics, Hamdard University.Duration of study is from December-2021 to November-2022.Various paracetamol based effervescent formulations (F1-F9) were prepared with different molarratio of citric-acid anhydrous and sodium-bicarbonate as independent variables.Design-Expert ® software was used to graphically express the influence of each factor.By novel approach; tablets were compressed at ambient temperature and relative-humidity; acid components were kept on one-side and basic ingredients on another side; both sides were separated by an inert-layer.Tablets were kept at accelerated humidity and temperature in normal packing for six months; after six months, F6 formulation was found acceptable based on effervescence-time (120 sec), pH-value (5.5) and other quality criterion.Parameters of assay, effervescence-time, pH-value and carbon-dioxide content were found within the set-limit.Hence; novel approach for developing effervescent formulation by separating acid components at one-side and basic ingredients on another side of tablet through inert-layer is workable under room temperature and humidity.It is expected that commercial production of tablets by this technique may reduce cost of effervescent products and no requirement for special packaging.
