Benzamil hydrochloride is a specific blocker of sodium channel (ENaC).

The specific ENaC blocker Benzamil hydrochloride adds to the luminal perfusate (106 M) significantly decreases baseline [Na+]i by 19.2 mM (n=5) and almost completely inhibits the [NaCl]L-dependent increasing in [Na+]i when coadministers with luminal AngII[2].

Intracerebroventricular injection of endothelin-1 (1 nmol) after intracerebroventricular preinjection of the vehicle of Benzamil hydrochloride markedly increases both mean arterial pressure and abdominal sympathetic nervous activity for 10 min. In SHRSP, intracerebroventricular infusion either of 1 or 10 nmol/kg/day Benzamil hydrochloride decreases systolic blood pressure (4th day: F=6.131, 1 nmol/kg/day, P<0.05, 10 nmol/kg/day, P<0.01; 5th day: F=6.842, 1 nmol/kg/day, P<0.05, 10 nmol/kg/day, P<0.01; 6th day: F=5.988, 1 nmol/kg/day, P<0.05, 10 nmol/kg/day, P<0.01; 7th day: F=7.935, 1 nmol/kg/day, P<0.01, 10 nmol/kg/day, P<0.01), urinary excretion of vasopressin (5th day: F=9.385, 1 nmol/kg/day, P<0.05, 10 nmol/kg/day, P<0.05; 6th day: F=8.783, 1 nmol/kg/day, P<0.01, 10 nmol/kg/day, P<0.01; 7th day: F=8.996, 1 nmol/kg/day, P<0.01, 10 nmol/kg/day, P< 0.01), and norepinephrine (3rd day: F=4.341, 1 nmol/kg/day, P<0.05, 10 nmol/kg/day, P<0.01; 4th day: F=9.865, 1 nmol/kg/day, P<0.01, 10 nmol/kg/day, P<0.01; 5th day: F=14.652, 1 nmol/kg/day, P<0.01, 10 nmol/kg/day, P<0.01; 6th day: F=13.376, 1 nmol/kg/day, P<0.01, 10 nmol/kg/day, P<0.01; 7th day: F=8.594, 1 nmol/kg/day, P<0.01, 10 nmol/kg/day, P<0.01) compare with vehicle[1].
