Sodium Pentathol

Sodium Pentathol

Sodium Pentathol was a compound which was used as a type of truth serum on Earth during the mid-20th century Earth.

While he was stuck in 1947 Earth, the the United States of America government used sodium pentathol on Quark to gain information about an anticipated attack from Mars. However, several injections of the drug did not produce results, which along with Quark's loud, high-pitched screams for mercy convinced Rex Denning to stop. (DS9: "Little Green Men")

The name Sodium Pentathol is actually a registered trademark; the generic name is sodium thiopental. Use of the name was due to common usage rather than product placement.
