ANUSOL HC vs POKONZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone, a corticosteroid, binds to glucocorticoid receptors, inhibiting phospholipase A2 activity and reducing prostaglandin and leukotriene synthesis. It also suppresses cytokine production and inflammatory cell migration, leading to decreased edema, erythema, and pruritus in anorectal tissues.
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.
Apply a thin layer to the affected area rectally 2 to 4 times daily, or after each bowel movement, for up to 7 days. Each application should not exceed 1 gram.
Intravenous: 0.1 mg/kg every 8 hours for 28 consecutive days per 6-week cycle.

Terminal elimination half-life of hydrocortisone is approximately 1.5-2 hours (range 1-3 h) in adults; clinical effect outlasts half-life due to intracellular receptor-mediated action.
Terminal elimination half-life 12-15 hours; clinically significant for once-daily dosing with steady-state achieved in 3-5 days
Renal (primarily as metabolites) >80%; fecal ~15%; <2% unchanged in urine due to extensive hepatic metabolism. Biliary excretion is negligible.
Primarily renal excretion (70-80% unchanged drug); biliary/fecal elimination accounts for 15-20%
