Generic Name: eplerenone (e-PLER-en-one)
Brand Name: Inspra
Inspra is used for:
Treating high blood pressure alone or along with other medicines. It is also used to improve survival in patients who have certain heart problems (left ventricular systolic dysfunction and congestive heart failure) following a heart attack. It may also be used for other conditions as determined by your doctor.
Inspra is an aldosterone blocker. It works by blocking the hormone aldosterone, which lowers the amount of sodium and water the body retains. This helps to lower blood pressure to help prevent strokes, heart attacks, and kidney problems.
Do NOT use Inspra if:
- you are allergic to any ingredient in Inspra
- you have severe kidney problems or high blood potassium levels
- you are taking Inspra to treat high blood pressure, and you have type 2 diabetes with protein in your urine
- you are taking clarithromycin, itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, or troleandomycin
- you are taking Inspra to treat high blood pressure, and you are taking potassium supplements or potassium-sparing diuretics (eg, amiloride, spironolactone, triamterene)
Contact your doctor or health care provider right away if any of these apply to you.
Before using Inspra:
Some medical conditions may interact with Inspra. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

Some MEDICINES MAY INTERACT with Inspra. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril), angiotensin-receptor blockers (eg, valsartan), potassium supplements, or potassium-sparing diuretics (eg, amiloride, spironolactone, triamterene) because the risk of high blood potassium levels may be increased
- Azole antifungals (eg, fluconazole, itraconazole, ketoconazole), macrolide antibiotics (eg, clarithromycin, erythromycin, troleandomycin ), nefazodone, protease inhibitors (eg, nelfinavir, ritonavir, saquinavir), or verapamil because they may increase the risk of Inspra's side effects
