FLUIDIL vs PERCORTEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluidil is a thiazide-like diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption and promoting diuresis.
Percorten (desoxycorticosterone pivalate) is a synthetic mineralocorticoid that binds to and activates the mineralocorticoid receptor (MR) in the renal distal tubule, leading to increased sodium reabsorption, increased potassium and hydrogen ion excretion, and water retention, thereby expanding extracellular fluid volume and increasing blood pressure.
5 mg orally once daily.
1-5 mg intramuscularly or subcutaneously daily with dose adjusted based on clinical response and electrolyte monitoring.

Terminal elimination half-life: 1.5-2 hours (prolonged in hepatic impairment to 4-6 hours).
Terminal elimination half-life is approximately 30-40 minutes. Clinically, the short half-life necessitates frequent dosing (e.g., every 6-12 hours) to maintain therapeutic effect in mineralocorticoid replacement.
Renal: 60-70% unchanged; biliary/fecal: <5%; hepatic metabolism: 25-35%.
Renal (biliary/fecal negligible). Approximately 50-70% of a dose is excreted as metabolites in urine; <5% unchanged.
