Mechanism of Action

Targets/IC₅₀/Ki	NKCC2
In vitro	Furosemide reversibly alters the responses to tones and clicks of the chinchilla basilar membrane in hair cells, causing response-magnitude reductions that are largest (up to 61 dB, averaging 25-30 dB) at low stimulus intensities at the characteristic frequency (CF) and small or nonexistent at high intensities and at frequencies far removed from CF. This compound also induces response-phase lags that are largest at low stimulus intensities (averaging 77 degrees) and are confined to frequencies close to CF. This chemical concentration- and time-dependently increases the formation of nitric oxide andprostacyclin. It leads to an enhanced release of kinins into the supernatant of the cells. It reversibly suppresses low Ca2+-induced epileptiform activity in hippocampus proper and blocks or significantly reduces different types of epileptiform discharges in the low Mg2+ model and the 4-aminopyridine model. This compound significantly inhibits cell growth in MKN45 cells, but not in MKN28 cells. It diminishes cell growth by delaying the G(1)-S phase progression in poorly differentiated gastric adenocarcinoma cells, which show high expression and activity of NKCC, but not in moderately differentiated gastric adenocarcinoma cells with low expression and NKCC activity.
In vivo	Furosemide (0.25 to 2 mg/kg), administered 4 hours before exercise, reduces right atrial pressure (RAP) and pulmonary arterial pressure (PAP) during exercise in dose-dependent manner in horse.
