Correction fixes unit label in feline P-glycoprotein study

Frontiers in Veterinary Science has published a correction to the 2025 paper “Assessment of clinically relevant drugs as feline P-glycoprotein substrates,” from Katrina L. Mealey and Neal S. Burke at Washington State University. The correction, published May 22, 2026, fixes a labeling error in Table 2: the concentration range was incorrectly shown as “MM” and should have been “μM.” The journal says the original article has been updated, and the correction does not describe any change to the study’s findings or drug classifications.

Why it matters: For veterinary professionals, this is a small but important fix because concentration units shape how readers interpret in vitro pharmacology data. The original study mapped a set of clinically relevant drugs as strong, moderate, weak, or non-substrates for feline P-glycoprotein, a transporter tied to drug disposition, blood-brain barrier protection, biliary excretion, and adverse interaction risk. A mislabeled unit could create confusion about exposure ranges even when the underlying results remain unchanged. (frontiersin.org)

What to watch: Watch for whether this feline P-gp substrate dataset is incorporated into future dosing guidance, interaction screening, or follow-up work on cats with suspected MDR1-related P-glycoprotein deficiency. (frontiersin.org)
