What is the application of geometric mean in pharmacy?

In pharmacy, the geometric mean is often used to analyze pharmacokinetic data, particularly when assessing the average concentration of a drug in plasma over time. It is especially useful for skewed data sets, such as drug concentrations that can vary widely among patients. By providing a more representative average, the geometric mean helps in evaluating dosage regimens and ensuring effective therapeutic outcomes. Additionally, it is employed in bioequivalence studies to compare the pharmacokinetic profiles of generic and brand-name drugs.
