REEXAMINATION OF LACTOPEPTINE[T]
Report to the Council on Pharmacy and Chemistry
In 1907 the Council on Pharmacy and Chemistry published a report on Lactopeptine. At that time it was shown that Lactopeptine did not have the composition claimed for it. The same claims as to composition are still being made for the product. In view of this fact, a second examination of Lactopeptine has been made and the result reported to the committee on chemistry. The report confirms the Council’s findings of six years ago. After adoption by the committee, it was adopted by the Council and its publication authorized.

SECOND EXAMINATION OF LACTOPEPTINE
Two specimens of Lactopeptine in original unbroken packages were recently examined. One of these was an American preparation said to be produced by the New York Pharmaceutical Association at Yonkers and the other an English preparation from John Morgan Richards and Sons, London.
When Lactopeptine was first examined by the Council about six years ago, it was found to be little more than weak saccharated pepsin, and did not contain the other ferments which were claimed by the manufacturers to be present. A statement concerning this was published in the Council Reports for 1905–1908, p. 43. Because of claims recently made by the exploiters that this preparation contains not only pepsin but also pancreatin, diastase, lactic acid and hydrochloric acid, and that the failure to recognize these must be due to the lack of ability of the chemists making the examination, it seemed worth while to undertake a new series of tests on samples from two sources mentioned, the products on the British and American markets. The label on the British sample gives the following as the composition:
| Sugar of Milk | 40 | ounces |
| Pepsin | 8 | ounces |
| Pancreatine | 6 | ounces |
| Ptyalin or Diastase | 4 | drachms |
| Lactic Acid | 5 | fl. drachms |
| Hydrochloric Acid | 5 | fl. drachms |
The label on the American sample gives no quantities but states that it “represents a combination of the principal digestive and enzymogenic agents, Pepsin, Pancreatin, Diastase, Lactic and Hydrochloric Acids, in the proper proportion to insure best results.”
