MedDRA

Medical Dictionary for Regulatory Activities (MedDRA) is maintained by the ICH (International Council for Harmonisation). It is the international standard for coding adverse events, medical history, and indications in clinical trials and post-marketing surveillance. MedDRA is organized in a five-level hierarchy: System Organ Class (SOC), High Level Group Term (HLGT), High Level Term (HLT), Preferred Term (PT), and Lowest Level Term (LLT).
