End of First Spanish Translation Program

By 1940 the USP Spanish edition had been adopted as an official standard in several countries, including Cuba, Panama, and the Dominican Republic. While the 1940 edition of the Spanish translation was marginally profitable—due to the isolation of Europe during World War II—the demand for later editions steadily decreased, and the program was discontinued in 1960 after being published for five decades. Changes in the political climate of Latin America, such as Castro's coup in Cuba, narrowed the market for the USP, and the advancement of pharmaceutical and medical science in Latin America allowed for the publication of national pharmacopeias in the region.
