*Opium (Opium), Opium, U.S.P.—The dried juice of the opium poppy. Yields not less than 9.5 per cent. of anhydrous morphine.
Action and Uses: Like those of morphine, but opium is absorbed more slowly, and is generally preferred in the treatment of the gastro-intestinal tract, especially for the purpose of checking diarrhea. It is ineffective for external or local application, because the opium alkaloids are not absorbed to any appreciable extent through the unbroken skin.
The routine use of complicated mixtures containing opiates deserves condemnation, since opium should not be prescribed unless it is adapted to the conditions of the individual patient.
Dosage: 0.06 Gm. or 1 grain (U.S.P.).
Acetum Opii (Acet. Opii), Vinegar of Opium, N.F.—Opium (10%) in diluted acetic acid, flavored with nutmeg and sugar.
Uses: An obsolete and superfluous preparation.
Dosage: 0.5 Cc. or 8 minims (U.S.P.).
*Extractum Opii (Ext. Opii), Extract of Opium, U.S.P. (Powdered Extract of Opium, Opii Extractum, P.I.).—One Gm. extract represents about 2 Gm. opium. Yields about 20 per cent. of anhydrous morphine.
