Hydroxychloroquine (HCQ) also came from Germany. In 1941 IG Farbenindustrie suggested to the French company Rhone-Poulenc that it carry out trials of a new drug known as Sontoquine. Three forms of Sontoquine were described: Sontoquine M (methane-bisoxy-naphthoate), Sontoquine C (hydrochloride or HCQ), and Sontoquine R (resorcin carbonate). The first field trials with these new drugs were conducted in North Africa but were interrupted by the collapse of Nazi Germany4. Chloroquine and Sontoquine were also patented in the United States in 1941 by the Winthrop Co. and approved by the US Food and Drug Administration in October 19495.
