Mepenzolate belongs to the diphenylmethanes, a subclass of benzene and substituted derivatives within the organic compounds. It is recorded as being found in or released from two sources: electrical and electronic equipment, specifically conductors or conductive bodies characterised by the conductive materials, and healthcare, pharmaceuticals, and veterinary products, specifically drugs for functional gastrointestinal disorders. The recorded exposure route for this compound is oral. At the molecular level, mepenzolate acts on three recorded protein targets. It functions as an antagonist of the muscarinic acetylcholine receptor M1 (CHRM1), the muscarinic acetylcholine receptor M3 (CHRM3), and the muscarinic acetylcholine receptor M5 (CHRM5).
