Racecadotril, also known as acetorphan, is an antidiarrheal drug which acts as a peripherally acting enkephalinaseinhibitor. Unlike other medications used to treat diarrhea, which reduce intestinal motility, racecadotril has an antisecretory effect—it reduces the secretion of water and electrolytes into the intestine. It is available in France (where it was first introduced in 1993 and is widely used) and other European countries, as well as most of South America and some South East Asian countries, but not in the United States. It is sold under the tradenames Hidrasec or, in France, Tiorfan.
Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
