  label: MedDRA Medical Dictionary for Regulatory Activities API
  description: MedDRA (Medical Dictionary for Regulatory Activities) and the WHO Drug Dictionary provide standardized medical
    terminology APIs for adverse event coding, drug safety reporting, and pharmacovigilance. APIs enable term lookup, hierarchy
    navigation, and coding validation for regulatory submissions to ICH, FDA, EMA, and other health authorities.
