The USP–NF is available as a Spanish Edition for Spanish-speaking pharmaceutical scientists and professionals. USP has used the most rigorous translation and quality control to develop the USP–NF Spanish Edition. The translation process was guided and directed by a special advisory group of volunteer scientific experts from many Spanish-speaking countries. The translation was thoroughly checked by bilingual (English/Spanish) USP staff scientists. USP–NF standards are enforceable by the U.S. Food and Drug Administration for medicines manufactured and marketed in the United States.
