get_drugGet the full profile for a drug by its RxCUI. Returns names, dosage forms, NDC codes, label sections, and related data. Get the RxCUI from search_drugs first if you only have a name. Args: rxcui: RxNorm Concept Unique Identifier, e.g. "1191" for aspirin.
get_drug_by_ndcGet a drug profile by its NDC (National Drug Code) package code. Use when you have an NDC from a label or packaging rather than a name. Args: ndc_code: NDC code, e.g. "0363-0160".
