The Zuellig Pharma Korea Consortium Database: An on-site drug wholesales database for pharmacoepidemiological
Objective:
To assess the value and representativeness of the Zuellig Pharma Korea Consortium (ZPK-C) database, which contains drug wholesales data collected in a weekly interval, for its prospective use as a data source for pharmacoepidemiology studies.
Materials And Methods:
Wholesales and nationwide claims data of antidiabetic and antihypertensive products were compared in 17 administrative regions using the defined daily dose per 100,000 inhabitants per day (DID) and its proportion for standardized evaluation.
Results:
We found regional concordance in 12 and 13 regions (out of 17) for antidiabetic and antihypertensive products, respectively, of which concordance was higher in rural than metropolitan regions.
Conclusion:
The ZPK-C showed potential as a valuable data source for pharmacoepidemiology research.

Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
Methods for Studying Drug Absorption: In vitro
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

How Data are Classified: Categorical Data
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
