THE value of the antihistaminic drugs in the treatment and prevention of the common cold and undifferentiated respiratory diseases has been investigated as follows: by observation of the effect of the drugs in naturally occurring respiratory infections; and by determination of the influence of the drugs on the occurrence and subsequent course of common colds developing after the experimental inoculation of normal volunteers.
