Opium Tincture, USP (Deodorized), is for oral administration. It is freed from unpleasant odor or nauseating substances by “denarcotization” with a petroleum distillate. Opium tincture is a clear, reddish-brown hydroalcoholic solution.
Each 100 mL contains 1 g of anhydrous morphine (represents the equivalent of 10 g of Powdered Opium, USP), alcohol, 19%, and water.
Opium has a very characteristic odor and a very bitter taste. The opiates are the most effective and prompt-acting nonspecific antidiarrheal agents.
