POKONZA vs TOPICORT LP
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.
Topicort LP (desoximetasone) is a corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. It binds to intracellular glucocorticoid receptors, leading to modulation of gene expression that suppresses inflammatory mediators such as prostaglandins, leukotrienes, and cytokines.
Intravenous: 0.1 mg/kg every 8 hours for 28 consecutive days per 6-week cycle.
Apply a thin film to the affected skin areas twice daily. Route: topical. Frequency: twice daily.

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 2-4 hours after topical application. This short half-life reflects rapid systemic clearance and minimal accumulation with once-daily dosing.
Primarily renal excretion (70-80% unchanged drug); biliary/fecal elimination accounts for 15-20%
Primarily renal (urinary excretion of metabolites and unchanged drug). Biliary/fecal elimination is minimal, accounting for <5% of the dose.
