์์ฉ ๊ธฐ์ : Amiloride acts directly on the **distal convoluted tubule** and **collecting duct** of the nephron. It blocks epithelial sodium channels (ENaC) โ inhibits sodium absorption โ decreases the electrical potential across the tubular epithelium โ reduces the driving force for potassium and hydrogen ion secretion. This leads to a failure of the normal renal concentration gradient, resulting in **sodium loss** (mild diuresis) and **potassium retention**.

Overdose primarily presents as **severe hyperkalemia**, **dehydration**, and **hyponatremia**. Clinical signs may include profound weakness, bradycardia, cardiac arrhythmias, and collapse. **Treatment:** Discontinue the drug immediately. Induce emesis or perform gastric lavage if ingestion is recent. Treat hyperkalemia aggressively (e.g., IV fluids, calcium gluconate, dextrose/insulin, or sodium bicarbonate as clinically indicated).
