Acetate of Potash. KO, C4H3O3 A compound of Potash 47.96. Acetic Acid 52.04, in 100 parts; or, 1 Eq. Potash=47, + 1 Acetic Acid=51 = 98, Eq. Wt.

Med. Prop. and Action. In doses of gr. xx. - gr. lx., it is an efficient and mild diuretic; in doses of gr. cxx. - gr. ccxl, it acts as a purgative; but in the latter character it is inferior to other saline purgatives, as it causes much griping and flatulence. When administered in continuous doses, it is absorbed into the system, the hydrogen and part of the carbon of the Acetic Acid become oxidized in the blood, and the salt appears in the urine in the form of carbonate, rendering that secretion alkaline, and generally producing an increase in its quantity. Mr. Easton observes that, in all cases in which it was administered, the urine was not only augmented in quantity, but that its solid constituents were increased in a remarkable degree. Dr. Golding Bird considers that in rheumatism, skin diseases, &c, it probably acts by altering and correcting a morbid condition (lactic acid?) of the blood. Its diuretic effect is increased by giving it largely diluted. It should be kept in well-stoppered bottles. Dose, as a diuretic, gr. xx. - gr. lx.; as a purgative, gr. cxx. - gr. ccxl Incompatible*. Mineral Acids; the Sulphates of Soda and Magnesia; Hy-drochlorate of Ammonia; Tartrates of Potash and Soda; solutions of Corrosive Sublimate; Nitrate of Silver, and some other salts of metals and earths.

G. Bird. He states that the Acetate, given with a mixture of sugar, water, and essence of lemons, acts with marvellous rapidity. In addition to this, he administers Pil. Sapon. c. Opio gr. v. night and morning; by this, he not only relieves the pain, but prevents the other remedy passing off by the bowels. If the liver be engorged, a mild mercurial may be employed. The dose usually employed is gr. xxx. every four hours. The vapour bath may be also employed. For his explanation of its action, see ante.
