Due to licensing restrictions, we’re not allowed to offer downloads of the MEDDRA ontology source file via our REST service, or from the BioPortal website. 

If you're a current UMLS license holder [1], please contact our technical program manager John Graybeal (cc'ed) for possible download options. (UMLS licenses are free and take about 5 business days to get approved).

Kind regards,
