Spironolactone, better known under the name Aldactone, is available from manufacturers such as Pfizer AG or Roche Pharma AG and others.

Spironolactone is a potassium-containing diuretic, which means that when the excess liquid is precipitated, it retains the potassium in the body and does not dissolve it, as is the case, for example. In other, stronger abrasion diuretics such as furosemide (Lasix), to a large extent from the body. This is desirable from a health perspective, since potassium plays a major role in the optimal function of the heart.
Spironolactone is an aldosterone antagonist and thus the counterpart of the body-borne hormone aldosterone. The higher the concentration of aldosterone in the body, the more fluid the organism stores. If the aldosterone level is lowered, for example by administration of a diuretic such as spironolactone, more water is excreted through the kidneys. Spironolactone is a mild drainage agent compared to other diuretics. It provides for a steady drainage and is taken by bodybuilders to the competition preparation several weeks before.
