Furosemide is known to be a loop diuretic, which functions primarily by inhibiting sodium reabsorption in the kidneys' loop of Henle, leading to increased urine production, or diuresis. This mechanism makes it effective in managing conditions such as edema and hypertension by promoting the excretion of excess fluid and electrolytes.

Furosemide is banned by the International Olympic Committee (IOC) because it can be misused by athletes to achieve weight loss or to dilute urine, potentially masking other prohibited substances or enhancing performance. The IOC's stance on furosemide aligns with efforts to maintain fair competition and prevent any advantage gained through unethical practices.

The other substances mentioned either do not cause significant diuresis or are not banned by the IOC. Salbutamol, primarily used as a bronchodilator, does not share the same diuretic properties and is allowed under specific therapeutic use conditions. Caffeine, while it has mild diuretic effects, does not qualify as a banned substance in most cases, although excessive consumption may result in penalties in specific contexts. Salicylates, commonly used to relieve pain and inflammation, are not associated with diuretic actions at all.
