The following is an epitome of the replies of the eleven members of this staff who had used the article or who expressed an opinion to the questions sent out by the Council:
1. Query: “Do you think it possible that such a preparation could be devoid of the usual effects of iodin preparations?”
Eight reply that they consider this, a priori, impossible; three stamp the statement as highly improbable, but do not care to say that it would be impossible. One of the correspondents remarks: “While distinctly taking the position that under many conditions we must accept clinical results which we find not explainable by our theoretical knowledge, where the conditions are so simple as in this case and where we know that the iodin, whether administered as hydrogen iodid or potassium iodid, must behave in the same way, after absorption, I believe that no properly educated and correct thinking physician can or will, after due consideration, fail to reject the claims of superiority made by the proprietors of this preparation.”
2. Query: “Would you consider it necessary to make clinical experiments to settle this question?”
Seven of the correspondents consider this superfluous; four of these have had some experience with the article. Four, who have not used this product, consider a clinical test advisable. Under Query 3 we discuss the results of such tests.
3. Query: “When using Gardner’s Syrup of Hydriodic Acid, have you ever noticed from it any of the objectionable effects of iodin preparations?”
Six of the correspondents have not used it, or are uncertain whether or not they used the product made by Gardner. One correspondent remarks: “Never used it. Repelled by claims of superiority which exaggerate disadvantages of potassium iodid and overlook the small amount of iodin used in the preparation advertised.” The five clinicians who have prescribed the preparation report as follows: 1. Objectionable iodin effects in two cases, both patients being intolerant of all iodin preparations. 2. Has only prescribed it once or twice, but thinks he has seen iodism in one case, some years ago; does not recall clearly. 3. No; but has used this make very little, and then always in very small but continued doses. 4. No, always used it in small doses. 5. Yes, several cases in children; typical coryza, etc., with doses of three drams three times a day.
Conclusions: It appears that typical iodism occurred in several cases, after doses corresponding to 10 grains or less of potassium iodid per day, and this is a rather limited clinical material. Objectionable iodin effects are, therefore, not uncommon. Several correspondents remark that the relative infrequency of iodism is easily explainable by the fact that syrup is rarely employed in conditions which demand an active iodin medication and that it is, therefore, always taken in small doses. In fact, the main if not the only point of superiority of the syrup appears to be in its flavor.
These clinical opinions and experiences, therefore, are in complete agreement with the judgment of the committee, namely, that the therapeutic claims made by the manufacturers for this article are exaggerated and misleading.
