Morphine and codeineare believed alone to give this reaction.
Ammonia= dissolves only traces of morphine; but narceine and codeine readily.
The codeine in the ammoniacal solution can be recovered by shaking up with benzene, and recognised by the red colour which the solid substance gives when treated with a little sugar and sulphuric acid.
Concentrated sulphuric acid dissolves codeine without colour, but after eight days the solution becomes blue; this reaction is quicker if the acid contains a trace of nitric acid.
The precipitates produced in solutions of narceine andcodeine are crystalline and very characteristic.
The treatment consisted of emetics, and afterwards tannin and codeine were given separately.
The physiological action of codeine on animals has been investigated by Claude Bernard, Magendie, Crum Brown and Fraser, Falck, and a large number of others.
The codeine has the advantage over all other opium preparations that it does not affect the digestive organs, and still acts in a soothing manner.
Codeine is only about one-third or one-fourth as toxic as morphine and consequently it may be given in a proportionately larger dose.

Codeine is one eighth the strength of morphine; heroin is three times as strong as morphine.
Morphine is the chief active principle, andcodeine and heroin are the chief derivatives of morphine.
I also found from my clinical comparisons that codeine has only one eighth the strength of morphine, yet in the end just as surely a producer of the drug habit similar to that of morphine itself.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "codeine" in a variety of sentences. We hope that you will now be able to make sentences using this word.
