Comparison of the efficacy of furosemide with two furosemide-triamterene combinations in the treatment of cardiac insufficiency.

Nine patients suffering from cardiac insufficiency were given furosemide and two furosemide-triamterene combination products in random order. A statistically significant diuretic response was achieved with all these preparations. The combination of furosemide and triamterene brought about a 'softer' diuresis, no hypokalaemia and the advantage of dosage as only one tablet, thus eliminating the need for taking two separate drugs.
