Actually it's three different chemicals that are used in the lethal injection process:
The first is a saline solution to keep the veins open.
The second is an anesthetic, sodium thiopenthal (better known by its well known trade name Pentothal, aka 'truth serum').
The third and final injection is pancuronium bromide, which paralyzes the heart.
Some states use potassium chloride as an additional chemical.
