Carbarsone

Description

Carbarsone, also known as p-ureidobenzenearsonic acid, is historically used as an amebicide in human and veterinary medicine and extensively employed in poultry and swine feed, often in combination with antibiotics to prevent conditions like blackhead in turkeys. It exhibits relatively low acute toxicity, prompting investigations into its safety for food additives under the Federal Food, Drug, and Cosmetic Act. Studies aimed at assessing its potential carcinogenicity in laboratory animals have shown negative evidence similar to other arsanilic acid derivatives, suggesting minimal risk under chronic ingestion conditions. Metabolically, carbarsone is converted to arsanilic acid, which has been observed in preliminary studies involving dogs at high doses.
