An improved effervescent tablet is provided. The tablet contains acetylisylic acid, a critical ratio of bicarbonate to acid, flavors, sweeteners, tableting aids, and optionally other medicinals. The tablet has improved hardness and stability and can be readily compressed into a relatively small (by weight and diameter) effervescent tablet.
