POKONZA vs PSORCON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Psorcon (diflorasone diacetate) is a corticosteroid that acts by inducing phospholipase A2 inhibitory proteins, collectively called lipocortins. It inhibits the release of arachidonic acid, thereby decreasing the formation of prostaglandins and leukotrienes, leading to anti-inflammatory, antipruritic, and vasoconstrictive effects.
Intravenous: 0.1 mg/kg every 8 hours for 28 consecutive days per 6-week cycle.
Apply a thin layer to affected skin twice daily. For scalp conditions, use lotion or shampoo as directed.

Terminal elimination half-life 12-15 hours; clinically significant for once-daily dosing with steady-state achieved in 3-5 days
Terminal elimination half-life is approximately 2 hours (range 1.5–3 hours) after topical application; clinical significance: short half-life allows twice-daily dosing.
Primarily renal excretion (70-80% unchanged drug); biliary/fecal elimination accounts for 15-20%
Primarily renal (about 70% as unchanged drug and metabolites); biliary/fecal elimination of approximately 30%.
