These tablets disintegrate either rapidly in water, to form a stabilized suspension, or disperse instantaneously in the mouth to be swallowed without the aid of water. So, it’s preferred for pediatric patients who cannot swallow a solid dosage form and the API is unstable if formulated in liquid formulation. Also helpful for patients having prolonged illness who are prone to nauseatic sensations if they have to swallow a tablet. The added advantage of this formulation is faster onset of action as compared to standard compressed tablet. The properties of the water dispersible tablet, such as porosity, hardness, disintegration time and increase in viscosity after dispersion are necessary to investigate during manufacturing which decides the product performance. The common examples of API formulated in this dosage form are analgesics e.g., aspirin, ibuprofen, etc.
