Acriflavine (INN: acriflavinium chloride) is a topical antiseptic. It has the form of an orange or brown powder. It may be harmful in the eyes or if inhaled. It is a dye and it stains the skin and may irritate. The hydrochloride form is more irritating than the neutral form. It is derived from acridine. Commercial preparations are often mixtures with proflavine.^[1] It is known by a variety of commercial names.

Uses

Medical use

Acriflavine was developed in 1912 by Paul Ehrlich, a German medical researcher, and was used during the First World War against sleeping sickness and as a topical antiseptic.^[2]

Other uses

Acriflavine is used in biochemistry for fluorescently labeling high molecular weight RNA.^[1]

It is used as treatment for external fungal infections of aquarium fish.^[3]

Research

Acriflavine might be effective in fighting common cold virus, and also aid the fight against increasingly antibiotic resistant bacteria ^[4]^[5]^[6] because it can cure (remove) plasmids containing antimicrobial resistance genes from Gram positive bacteria.^[7]

Since 2014, acriflavine has been undergoing testing as an antimalarial drug to treat parasites with resistance to quinine and modern anti-parasitic medicines.^[8]

Legal status
