ABSTRACT:
A three layer effervescent tablet includes a first layer carrying a first effervescent reactant, and a second layer carrying a second effervescent reactant, with the first and second layers, separated by an interposed layer of a material which does not react with either effervescent reactant. This provides an effervescent tablet that does not require any of the special material, handling, or packaging considerations normally needed for effervescent tablets.
