  "description" : "MedDRA is a multilingual standardised international medical terminology which can be used for regulatory communication and evaluation of data pertaining to medicinal products for human use.  MedDRA is designed for use in the registration, documentation and safety monitoring of medicinal products through all phases of the development cycle (i.e., from clinical trials to post-marketing surveillance).#13;\n\r\nMedDRA is structured as a five level hierarchy. System Organ Classes (SOCs) are the broadest terms (e.g., Cardiac disorders, Investigations). The lowest level of the terminology is the Lowest Level Term (LLT) level.",
