Common NameCilnidipine
DescriptionCilnidipine belongs to the class of organic compounds known as dihydropyridinecarboxylic acids and derivatives. Dihydropyridinecarboxylic acids and derivatives are compounds containing a dihydropyridine moiety bearing a carboxylic acid group. Based on a literature review very few articles have been published on Cilnidipine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Cilnidipine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cilnidipine 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.
