Having had some experience with both SNOMED and RXNORM (for scraping and ETL for updates), you need login credentinals for both and I'm not sure how much they cost. Also they come in some large zip files (some are nested) so if you want to process it efficiently you should probably think about reading a particular file located inside, write to disk, process it, and deleting it and move on to the next without extracting it as whole.
