The other three products use R.P. Scherer's Zydis freeze-dried drug delivery system. All four products contain mannitol, which provides a pleasantly cool, sweet taste, relatively free from the chalkiness or grittiness frequently associated with the dissolution of tablets in the mouth. If you have not tried one of these formulations yourself, you really should, soon. As can be expected, these products are sensitive to moisture and humidity and the packaging has been designed with this in mind. Except for Tempra, all the tablets are double-wrapped, first in foil and then in individual blisters.
Tempra tablets are in sturdy, opaque childproof blisters.
This is clearly indicated on all four products. Obviously, they should not try to administer the tablets with wet hands. The tablets should be stored in a dry place. You might want to suggest that the opened foil pouch be folded closed to provide extra protection. The leaflet accompanying the Imodium quick-dissolve tablets warns of a burning or prickling sensation on the tongue immediately after taking a tablet, and assures that this will pass quickly.
