Codeine

 

an alkaloid contained in opium. Codeine is similar to morphine in chemical structure; however, its analgesic effect is less powerful. It relieves irritability of the coughing center. Codeine or codeine phosphate is prescribed for coughs. It is administered in the form of tablets or powders, mixed with sugar, sodium hydrocarbonate, terpin hydrate, thermopsis, and licorice powder. Codeine, in combination with soporifics and bromide preparations, is used as a sedative. Codeine is not prescribed for children. Prolonged use of codeine may cause addiction.
