BROMIDES. 307
BROMIDES.
Bromides are diffusible agents which rapidly pass into the
blood, and in large doses can be detected in the faeces and intesti-
nal mucus, owing to a portion of the agent not being absorbed.
They depress the heart's action, and also respiration and animal
temperature ; in some cases large doses may cause transient ex-
citement, giddiness and intoxication. Moderate doses have a
tranquillizing effect and refreshing sleep, and lower the sensibility
to pain and irritation. Their immoderate use will cause paralysis
of the muscles, and a condition known as bromism^ the symptoms
of which may be extreme pallor and anemia, dilated pupils, slow
and feeble action of the heart, breathlessness and quickened
pulse on slight exertion, acne, skin eruption, cool extremities,
tremulous and uncertain movements, want of tactile feeling, re-
laxation of the genitals, dry fauces, difficult deglutition, and weak
mind.
Ammonii Bromidum — Bromide of Ammonium. Formula.
—NH^Br. In the form of colorless, transparent crystals, or a
white granular salt, with a pungent, saline taste, neutral reaction,
and no odor. Ammonii Bromidum is soluble in 1.5 parts of
water, in 150 parts of alcohol at 60° F., and in 0.7 part of boil-
ing water.
Dose.—Gr. x to 5ss, considerably diluted.
Calcii Bromidum — Bromide of Calcium. Formula.
CaBrj. In the form of a white granular, deliquescent salt, with
a pungent, saline, bitter taste, and no odor. It has a neutral re-
action, and is soluble in 0.7 part of water, and in i part of
alcohol.
Dose.— '3] to 5ij-
LiTHii Bromidum— Bromide of Lithium. Formula.—LBr.
In the form of white, granular, deliquescent salt, with a pungent,
bitter taste, and a neutral reaction. Quite soluble in water and
alcohol.
Dose.—Gr. V to .3ij.
Sodii Bromidum— Bromide of Sodium. Formula.—NaBr.
In the form of small colorless crystals, or a white crystalline
powder, with a saline taste, neutral reaction and no odor. It is
