From the Guidelines
Add a potassium-sparing diuretic, such as spironolactone 25 mg orally daily, to help manage potassium levels and fluid overload. The current medications, including metoprolol, nifedipine, losartan, and Imdur, are acceptable for managing hypertension, but may need dose adjustments 1. Consider increasing the dose of losartan to 100 mg orally daily and metoprolol to 100-200 mg orally twice daily. The recently added medication, Embrel (Etanercept), is not directly related to the management of hypertension or fluid overload, and its interaction with the current medications should be monitored closely 1. Continue IV Lasix (Furosemide) as needed to manage fluid overload, and consider adding a loop diuretic enhancer, such as metolazone 2.5-5 mg orally daily, to enhance the effects of IV Lasix 1.
- Key considerations:
- Close monitoring of blood pressure, renal function, and electrolyte levels is essential 1.
- The patient's renal function and potassium levels should be closely monitored due to the risk of hyperkalemia associated with the use of losartan and potential interactions with other medications 1.
- The use of spironolactone may help manage potassium levels, but its effectiveness in reducing blood pressure should also be considered 1.
- The patient's response to the current medications and the added medication should be closely monitored, and adjustments should be made as needed to achieve optimal blood pressure control and manage fluid overload 1.

From the Research
Patient's Current Condition
The patient has acute and chronic renal failure, uncontrolled hypertension, signs of fluid overload on chest x-ray, and lower extremity swelling. The patient is currently on metoprolol, nifedipine, losartan, and isosorbide mononitrate, with recent addition of etanercept and ongoing IV furosemide therapy.
Considerations for Additional Medication
Given the patient's condition, the following considerations should be taken into account:
- The patient is already on IV furosemide, a loop diuretic, which is commonly used to treat fluid overload and hypertension 2.
- The addition of a thiazide diuretic, such as metolazone or chlorothiazide, may be considered to enhance diuresis and improve blood pressure control 3, 4, 5.
- Metolazone has been shown to be effective in patients with acute decompensated heart failure and diuretic resistance, with a significant increase in urine output and improvement in congestion score 6.
- Chlorothiazide has also been shown to be effective in increasing urine output and improving diuretic response in patients with heart failure and renal dysfunction 5.
Potential Additional Medications
Based on the evidence, the following medications could be considered:
- Metolazone: a thiazide diuretic that can be used to enhance diuresis and improve blood pressure control 3, 4, 6.
- Chlorothiazide: a thiazide diuretic that can be used to increase urine output and improve diuretic response in patients with heart failure and renal dysfunction 5.
- Other diuretics, such as spironolactone or eplerenone, may also be considered, but their use would depend on the patient's specific condition and response to treatment 2.
Key Considerations
When considering additional medication, the following key considerations should be taken into account:
- The patient's renal function and potential for worsening renal function with the addition of a new diuretic 3, 5.
- The patient's electrolyte balance and potential for electrolyte abnormalities with the addition of a new diuretic 3, 5.
- The patient's blood pressure and potential for hypotension with the addition of a new diuretic 2, 3.
