The dose of dilute nitric acid (Acidum Nitricum Dilutum, B. P.)is 3 to 15 minims (), well diluted, and taken through a tubeto protect the teeth. An exceedingly strong preparation, Acidum Nitricum Fumans, isofficial in the B. P. NITRITE OF POTASSIUM. Nitrite of potassium is a salt used largely in modern medicine totake the place of nitroglycerin, as it possesses greater stability, andis therefore more lasting in its effects (Fig. 56). It is used for the Minutes Hour 1 15 30 1.

The dose is from 3 to 5 grains (), althoughmuch larger doses have been employed. These larger doses are,however, not devoid of danger. Nitrite of potassium is eliminatedby the lungs and by the kidneys as a nitrate. (See Nitroglycerin.) Cobalto-nitrite of Potassium. This preparation has been employed successfully as a substitutefor the nitrite of potassium. As it is a more stable compound, it isless rapidly broken up in the system, and so exercises a more pro- 396 DRUGS longed influence. For this reason it does not act so vigorously orsuddenly, which is a great advantage in some cases. Its use isidentical with that of the rest of the nitrite group. The dose is Jgrain () every three hours. NITRITE OF SODIUM. Sodium nitrite (So
