POCA System Overview
The Phonetic and Orthographic Computer Analysis (POCA) program is a software tool that uses an advanced algorithm to determine the orthographic and phonetic similarity between two drug names. The program can compare a drug name against multiple drug names found in several different “data sources” contained in the software. The data sources are:
- Drugs@FDA (updated monthly)
- RxNorm (updated monthly)
- Suffixes in the proper name of approved biological products (updated monthly)
- United States Adopted Names (updated twice a year)
