Tripamide is an orally active sulfonamide-derived diuretic antihypertensive agent[1].

In Vitro

Tripamide (less than 10 μg/ml) does not modify the membrane potential and resistance, but does suppress the spike evoked by outward current pulses in the presence of 3-5 mM TEA[1].
In the mesenteric artery, Tripamide suppresses the amplitude of e.j.ps evoked by perivascular nerve stimulation. However, the facilitation process produced by repetitive stimulation is less affected by Tripamide[1].

In Vivo

In rats loaded orally with 25 ml/kg of normal saline, Tripamide (0.6-160 mg/kg) increases urine volume and sodium and chloride excretion in a dose-dependent fashion. Only at a dose of 160 mg/kg, there an increase in potassiumexcretion in rats[2].
Tripamide has anti-hypertensive effects, during administration to spontaneously hypertensive rats at a dose of 10 mg/kg/day for 4 weeks, tripamide doubled urine volume and sodium excretion, while potassium excretion is increased by <50% in rats[2].
