| Common Name | Lofepramine |
|---|
| Description | Lofepramine belongs to the class of organic compounds known as dibenzazepines. Dibenzazepines are compounds with two benzene rings connected by an azepine ring. Azepine is an unsaturated seven-member heterocycle with one nitrogen atom replacing a carbon atom. Lofepramine is a very strong basic compound (based on its pKa). In humans, lofepramine is involved in imipramine metabolism pathway. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lofepramine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lofepramine 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. |
