Schmickers, the tablet that Shan is talking about is a losec mups, basically it is a lot of tiny beads but these are enteric coated, so they can withstand the stomach acids. The actual tablet is able to be dissolved, just not the beads.

You are thinking of the compound in which they crush the tablets fully and this needs to be suspended in a bicarbonate solution so that this neutralises the acid on the way down so that the losec gets to the stomach whole.

Losec is used a lot in kids these days. Hope that helps!
