The Analgetic Action of Morphine, Eserine and Prostigmine Studied by a Modified Hardy‐Wolff‐Goodell Method.

Abstract
Summary.: A slight modification of the Hardy‐Wolff‐Goodell method for measuring pain threshold on man is described. Eserine raises the pain threshold. Prostigmine raises the pain threshold. Prostigmine greatly potentiates and prolongs the analgetic action of morphine.
