Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Peptides and proteins differ from conventional chemical entities in their sensitivity to numerous environmental factors and their susceptibility to different degradation pathways. Therefore, complex analytical methodologies are necessary to characterize their molecular entity as well as to detect and quantify the possible degradation products. The formulation of these molecules for a pharmaceutical product requires stabilization by various excipients. Most of the products are brought to market as solutions or lyophilisates. In the first part, this article presents a comparison between the degradation profile of a peptide (calcitonine) and a protein (human growth hormone), in solution and as a freeze-dried product. The various analytical methods used to characterize and identify the degradation products are reviewed and discussed. The second part contains an overview of the different formulation strategies for calcitonine and human growth hormone. Finally, the different stress conditions used to obtain stability data are discussed critically. This leads on to general comments on the design of stability studies for peptide and protein drugs as pharmaceuticals taking into consideration the official guidelines.
