Abstract
A chewable tablet comprises a medicament dispersed in a chewable base, such as mannitol, together with an effervescent couple, such as citric acid-sodium bicarbonate. The combination of effervescence and chewability with optional flavorings improves the taste characteristics of the medicament in oral administration. A disintegrant such as microcrystalline cellulose may be added to give the patient the option of dispersing the tablet in water.
