Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Topical corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. Binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.
POKONZA (ponazuril) is a triazine antiprotozoal agent that inhibits the mitochondrial electron transport chain at the cytochrome bc1 complex, disrupting the parasite's energy metabolism and leading to its death. It is active against apicomplexan parasites such as Toxoplasma gondii, Neospora caninum, and Sarcocystis neurona.
Topical: Apply a thin layer to affected area once or twice daily. Maximum: 30-60 g per week. Not for use >2 consecutive weeks or on >50% of body surface.
Intravenous: 0.1 mg/kg every 8 hours for 28 consecutive days per 6-week cycle.

Terminal elimination half-life: 30-40 hours; clinically significant for once-daily dosing and prolonged action
Terminal elimination half-life 12-15 hours; clinically significant for once-daily dosing with steady-state achieved in 3-5 days
Renal (approximately 60-70%) as conjugated metabolites; biliary/fecal (approximately 20-30%)
Primarily renal excretion (70-80% unchanged drug); biliary/fecal elimination accounts for 15-20%
