Common NameRiociguat
DescriptionRiociguat, also known as adempas or bay 63-2521, belongs to the class of organic compounds known as pyrazolopyridines. Pyrazolopyridines are compounds containing a pyrazolopyridine skeleton, which consists of a pyrazole fused to a pyridine. Pyrazole is 5-membered ring consisting of three carbon atoms and two adjacent nitrogen centers. Pyridine is a 6-membered ring with four carbon and one nitrogen atoms. Based on a literature review a significant number of articles have been published on Riociguat. This compound has been identified in human blood as reported by (PMID: 31557052 ). Riociguat is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Riociguat is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
