Why should I take Alka-Seltzer effervescent tablets for heartburn relief instead of a heartburn relief medication in a tablet I simply swallow?

There are multiple advantages to using Alka-Seltzer effervescent products. In short: the medicine dissolves fast and goes to work instantly, neutralizing acid on contact. Because the medicines in Alka-Seltzer effervescents are in solution prior to ingestion, they do not require time to dissolve in the stomach like similar active ingredients taken in a tablet form.
