Note: This tool uses web scraping to access Google Scholar since it doesn't provide a public API. It includes rate limiting protection and stealth measures to avoid detection.

🏥 Drug Nomenclature Tools

search-drug-nomenclature

Search for drug information using RxNorm (standardized drug nomenclature).

Input:

• query (string): Drug name to search for in RxNorm database

Output:

• Standardized drug information with RxCUI codes, synonyms, and term types
