So you have these 'fizzing' tablets, that are to the best of my knowledge referred to as effervescent tablets. The wiki page provides some details, including that they are tablets which are designed to dissolve in water, and release carbon dioxide.
However, I haven't been able to find out what the benefit is of a normal orally taken tablet dispersed in water, versus an effervescent tablet?
For example, take acetylcycteine against thick mucus - it comes in various forms, including regular tablets and effervescent tablets as well.
- Is it just to add some carbonic acid to the water to make it sparkling to make it taste better?
- Is it a method to dissolve materials quicker by the generation of bubbles?
- Is it to make the water more acidic by generating carbonic acid?
- Is there a more pharmacological reason for the use of effervescent tablets?
