From: Cetirizine per os: exposure and antihistamine effect in the dog
Histamine-induced wheal diameter over time relative to pre-medication values in eight dogs receiving either control treatment (upper plot, a) or treatment with cetirizine (lower plot, b) per os. * denotes statistically significant (P < 0.004, the Šisák-corrected P-value for repeated measurements) smaller diameter after treatment with cetirizine compared with the control treatment
