It differs from opium in being le stimulant, le constipating, and le likely to produce disagreeable after-effects. On account of its insolubility in water, morphin is used principally in the form of its salts. The dose of the salts of morphin is gr. }&-}£ (0.008-0.032). M. acetate, morphinae acetas, Cj7H]9N03C2- H402 -)- 3^20. From it are prepared Liquor morphinae a cet at is (B. P.) (gr. to the fluidram), dose rr\xx-xl (1. 3-2. 6), and Injectio morphinae hypodermic a (gr. j in 10 minims). M. hydro chlorate, morphinae hydrochloras, CnH19N03.HCl -f 3H20. From it are prepared Liquor morphinae hydrochloratis (B. P.) (gr. to the fluidram), dose rr^xv-xxx (1.0-2.0); Sup posit or i a morphinae (B. P.) (gr. each); Tinctura chloroform i et morphinse (gr. y% to the fluidram); Trochi sci morphinse (B. P.) (gr. 3^), and Trochi sci morphinse et ipecacuanhas (B. P.) (gr. -^). M. phthalate (unofficial) is employed hypodermically. M. sulphate, morphinse sulphas (C17H19N03)2H2S04 -f 5H20. From it are prepared: Liquor morphinse sulph at is (B. P.), dose rt^x-xl (0.65-4.0); Pulvis morphines compos it us, Tully’s powder, dose gr. x (0.65), containing gr. */(, (0.01) of morphin sulphate; Trochi sci morphinse compos it i (U. S. P.), each containing gr. -^ (0.0016), and Liquor morphinse hypodermic us (N. F.), Magendie’s solution, containing 16 grains to the fluid ounce. M. tartrate (unofficial) is employed for hypodermic use. Morphinism The condition (morf -fin-izm) caused [morphin’]. by the habitual I. use of morphin. 2. The morphin-habit. Morphinomania, 404
