What is the definition of an effervescent tablet?

An effervescent tablet is specifically designed to dissolve in water and release carbon dioxide, which creates fizz or bubbles. This process not only facilitates the rapid dispersion of the active ingredients in the solution, allowing for quicker absorption in the body when ingested, but it also masks the taste of certain medications that may not be pleasant to consume.

The other choices describe different types of tablets or forms of medication. For example, some tablets are formulated for extended-release to provide a gradual release of medication over an extended period, ensuring consistent delivery of the drug. Solid forms of liquid medications refer to products like suspensions that have been dried into a powdered form, which when mixed with water would reconstitute into liquid medication. Lastly, there are tablets specifically designed to coat the stomach, which are formulated to be more tolerable when taken by patients who have sensitive stomachs. However, none of these options capture the unique fizzy dissolution characteristic of an effervescent tablet.
