Why have the official dates changed?
A. Beginning in 2007, USP extended the official dates to provide users additional time to adopt revisions made to the compendia. The new implementation periods give USP 32–NF 27 Spanish Edition users four months from publication date to implement new official texts as opposed to the previous 60–days. Each annual subscription to the Spanish USP–NF includes the main edition and two Supplements as well as access to USP scientific, technical, and customer service support.Each annual subscription to the Spanish USP–NF includes the main edition and two Supplements as well as access to USP scientific, technical, and customer service support.
