Indication: 1. Edema diseases: It is used in combination with other diuretics to treat edema diseases such as congestive edema, ascites caused by liver cirrhosis, and renal edema. The purpose is to correct the increased secondary aldosterone secretion associated with the above diseases and counteract the potassium excretion effect of other diuretics. It is also used to treat idiopathic edema. 2. Hypertension: It is used as an auxiliary drug for the treatment of hypertension. 3. Primary aldosteronism: Spironolactone can be used for the diagnosis and treatment of this disease. 4. Prevention of hypokalemia: It is used in combination with thiazide diuretics to enhance the diuretic effect and prevent hypokalemia.

Indication: Electrolyte supplement. Used for: 1. Treatment of hypokalemia caused by various reasons. Such as insufficient food intake, vomiting, severe diarrhea, use of potassium-excreting diuretics, hypokalemic familial periodic paralysis, hypokalemia caused by long-term use of glucocorticoids and supplementation of hypertonic glucose, etc. 2. Prevention of hypokalemia. When the patient has potassium loss, especially if hypokalemia is harmful to the patient (such as patients using digitalis drugs), preventive potassium salt supplementation is required, such as eating very little, severe or chronic diarrhea, long-term use of adrenocortical hormones, potassium-losing nephropathy, Bartter syndrome, etc. 3. Frequent, multifocal premature beats or rapid arrhythmias caused by digitalis poisoning.
