What kind of diuretics is triamphenanthrene?

Aminopteridine is a potassium-preserving diuretic. Its diuretic effect is very light, but it has a strong potassium-preserving effect. Its mechanism of action is different from aldosterone. It acts directly on the sodium channel above the distal convoluted tubules of the kidney, reducing the entry of sodium ions, thus reducing potassium ion secretion. It is mainly aimed at edematous diseases, such as liver cirrhosis, heart failure, severe hypertension, edema caused by chronic nephritis, etc. It is often used in combination with potassium diuretics, thus reducing the patient's potassium loss and maintaining water electrolyte balance. The above health science knowledge is for reference only, and the specific situation needs to be checked in a regular hospital and judged by a professional doctor.
