Drug data recoding is commonly used in analyses of drug utilization rates, drug risks and side effects, and drug abuse and its prevention. Classification of a specific drug into a predetermined category using drug codes is complex. There are more than 100,000 brands of drugs on the market in the United States with more than 40,000 generic name codes, and some drugs are combinations of different ingredients. In addition, some drugs have multiple therapeutic uses, and thus, the most appropriate drug category may vary depending on the specific analysis. In this paper, a flexible SAS macro is presented for recoding drug data into groups using the SAS INPUT() and PUT() functions according to a format defined for drug codes in the FORMAT procedure.
