AT-7 - General Information

A chlorinated bisphenol antiseptic with a bacteriostatic action against Gram-positive organisms, but much less effective against Gram-negative organisms. It is mainly used in soaps and creams and is an ingredient of various preparations used for skin disorders. (From Martindale, The Extra Pharmacopoeia, 30th ed, p797)


Pharmacology of AT-7

AT-7, a detergent cleanser, is an antibacterial sudsing emulsion for topical administration. It is a bacteriostatic cleansing agent. It cleanses the skin thoroughly and has bacteriostatic action against staphylococci and other gram-positive bacteria. Cumulative antibacterial action develops with repeated use. Cleansing with alcohol or soaps containing alcohol removes the antibacterial residue.

AT-7 Contraindications

Do not use on burned or denuded skin; as an occlusive dressing, wet pack or lotion; as vaginal pack or tampon, on mucous membranes or for routine prophylactic total body bathing.

Additional information about AT-7

AT-7 Indication: For use as a surgical scrub and a bacteriostatic skin cleanser. It may also be used to control an outbreak of gram-positive infection where other infection control procedures have been unsuccessful.
Mechanism Of Action: The primary mechanism of action of hexachlorophene, based on studies with Bacillus megatherium, is to inhibit the membrane-bound part of the electron transport chain, respiratory D-lactate dehydrogenase. It induces leakage, causes protoplast lysis, and inhibits respiration.
