A Food Effect Study of 60mg ER Torsemide

Immediate Release (IR) Torsemide is a highly effective natriuretic drug but its short duration of action is a major drawback, which allows significant post-dose sodium retention, and as consequence, limits salt loss in patients with heart failure unless dietary salt intake is severely restricted. Extended Release (ER) torsemide is being developed to address this drawback by prolonging the duration of action to increase sodium excretion even in patients who consume high salt diet. Since 60mg ER torsemide is a new strength and dosage form, this study will test 60mg ER torsemide for a food effect in healthy volunteers who are either fasting or consuming a high-fat meal (fed). The primary endpoint of the study is full pharmacokinetics measurements after a single dose of 60mg ER torsemide. The secondary endpoints are 24h sodium excretion and total urinary excretion.
