RT Journal Article SR Electronic T1 Ethacrynic acid JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 6 OP 8 DO 10.1136/dtb.4.2.6 VO 4 IS 2 YR 1966 UL http://dtb.bmj.com/content/4/2/6.abstract AB Ethacrynic acid (Edecrin - MSD), like chlorothiazide, is the product of an intensive search for substances with affinity for sulphydryl groups - a property shown in vitro that is closely linked with clinical diuretic potency. It is an aromatic oxyacetic acid which dissolves poorly in water, well in lipids and is acidic; these properties suggest that it will bind strongly to tissue and plasma proteins.
