Caffeine

What does Caffeine in effervescent tablets actually mean.

Not sure what you are asking but caffeine is added to tablets to help boost alertness, give you a boost.
I'd rather drink a cup of coffee

[calmck]

It means that a tablet that fizzes when mixes with a liquid has caffeine in it. Probably sold as an energy boosting drink

[Old_Geezer]

Probably just means that caffeine is one of the constituents in the tablet. It's the 'wake up' stuff you get in tea & coffee; and some sodas.

Caffeine is added to some painkillers to help them work better.

[Vagus]

For example, solpadine plus, which you dissolve in water, contains paracetamol, codeine, and caffeine.
Other types of painkillers which also contain caffeine are also available.

[Hopkirk]

It's not the caffeine that fizzes, it's just one of the ingredients.

[Zacs-Master]

It’s in there to give you a little buzz and make you think the tablets are working better than they actually are.

[pastafreak]

It's what vagus said.

Caffeine isn't just added to painkillers, it's in a lot of effervescent supplements like Berocca
