Access the National Drug Codes on the U.S. Federal Drug Administration website using a searchable database online or printed NCD Directory, if available. Choose one of the other available formats, such as Excel, Corel WordPerfect and Adobe Acrobat Reader, if a usable format is not returned, states the FDA.
After the implementation of the Drug Listing Act of 1972, registered drug establishments processing drugs for commercial distribution are required to submit information about their processes for each product. Current information for each product is stored regarding processing, manufacturing, preparing, compounding and propagating drug products. National Drug Codes, comprised of three-tiered numbers, identify drug products. These numbers are unique and universally distinguish each drug. Entering new information every day in the NCD Directory, the FDA uses the database for enforcing the Drug Listing Act, says the FDA.
Following the guidelines of the Drug Listing Act, drug establishments are required to submit updates in June and December. Drug processors may submit changes as they occur or users finding errors may also contact the FDA, submitting identified anomalies in the database. As of 2009, electronic submissions regarding human drugs are the only acceptable way of registering and listing information for these drugs. Neither hard copies nor paper copies of forms are acceptable, states the FDA.
