Iodide of ethyl acts chiefly by virtue of the iodine element, and very slightly, if at all, as an anaesthetic ethyl compound. It introduces iodine very rapidly into the system, and has been chiefly used to stimulate the respiratory passages, and thus to act as an antispasmodic in asthma attended by scanty or tough secretion. In some instances it gives instant relief.
