Droga Usi

Triamterene pill combines Triamterene and Hydrochlorothiazide. Triamterene ia potassium-conserving (antikaliuretic) diuretic with relatively weak natriuretic properties. Hydrochlorothiazide is a diuretic and antihypertensive agent. It blocks the renal tubular absorption of sodium and chloride ions.

Come utilizzare

Classe di Droga e il Meccanismo

Triamterene is a potassium-conserving (antikaliuretic) diuretic with relatively weak natriuretic properties. It exerts its diuretic effect on the distal renal tubule to inhibit the reabsorption of sodium in exchange for potassium and hydrogen. With this action, triamterene increases sodium excretion and reduces the excessive loss of potassium and hydrogen associated with hydrochlorothiazide. Triamterene is not a competitive antagonist of the mineralocorticoids and its potassium-conserving effect is observed in patients with Addison's disease, i.e., without aldosterone. Triamterene's onset and duration of activity is similar to hydrochlorothiazide.

Hydrochlorothiazide is a diuretic and antihypertensive agent. It blocks the renal tubular absorption of sodium and chloride ions. This natriuresis and diuresis is accompanied by a secondary loss of potassium and bicarbonate. Onset of hydrochlorothiazide's diuretic effect occurs within two hours and the peak action takes place in four hours. Diuretic activity persists for approximately six to twelve hours.

Dose

If you miss a dose of Triamterene and are taking it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Avvertenze/Precauzioni

Do not use Triamterene if:

• you are allergic to any ingredient in Triamterene;
• you are taking potassium supplements, another potassium-sparing diuretic (e.g., amiloride), or an aldosterone blocker (e.g., eplerenone);
• you are unable to urinate or have high blood potassium levels or severely decreased liver or kidney function.

• Triamterene may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Triamterene with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Check with your doctor before you use a salt substitute or a product that has potassium in it.
• Tell your doctor or dentist that you take Triamterene before you receive any medical or dental care, emergency care, or surgery.
• Lab tests, including blood electrolytes, blood cell counts, kidney and liver function tests, blood uric acid levels, and blood pressure, may be performed while you use Triamterene. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
• Use Triamterene with caution in the elderly; they may be more sensitive to its effects.
• Triamterene should not be used in children; safety and effectiveness in children have not been confirmed.
