Study Notes
Kidney Disease Management and Medication Dosing
- Common medications and substances that can cause renal disease include aminoglycosides, NSAIDs, amphotericin B, polymyxins, cisplatin, radiographic contrast dye, cyclosporine, and loop diuretics.
- Creatinine clearance (CrCl) is calculated using the Cockcroft-Gault equation, which takes into account patient age, serum creatinine (SCr), and weight.
- Blood urea nitrogen (BUN) and SCr are used to estimate kidney function, with BUN measuring urea levels and SCr indicating muscle metabolism. Normal SCr range is 0.6-1.3 mg/dL.
- The Cockcroft-Gault equation for CrCl is commonly used for medication dosing, but its accuracy may be affected by low muscle mass, obesity, liver disease, pregnancy, or high muscle mass.
- Pharmacists typically base medication dosing recommendations on CrCl, while a few specific drugs use glomerular filtration rate (GFR) for dosing adjustments, such as SGLT2 inhibitors and metformin.
- CKD-EPI and MDRD equations are used for staging kidney disease and dosing select drugs like metformin and SGLT2 inhibitors.
- Estimated GFR (eGFR) is calculated using the MDRD and CKD-EPI equations, with albuminuria being a key indicator of kidney disease severity.
- GFR and degree of albuminuria are used to assess the severity of kidney disease, with a GFR < 60 mL/min/1.73 m2 and/or albuminuria indicating chronic kidney disease (CKD) and the need for specific treatments.
- Hypertension causes and worsens CKD, with a target systolic blood pressure (SBP) < 120 mmHg recommended for patients with hypertension and CKD.
- An ACE inhibitor or ARB is first-line for patients with CKD, hypertension, and albuminuria, as renin-angiotensin-aldosterone system (RAAS) inhibition reduces CKD progression.
- When starting treatment with an ACE inhibitor or ARB, the baseline SCr can increase by up to 30%, which is expected and should not prompt treatment cessation.
- The 2021 KDIGO Guideline on Blood Pressure in CKD recommends a lower target SBP for those with hypertension and CKD, compared to the general population.
Phosphate Binders in Chronic Kidney Disease
- Initial CKD treatment involves dietary phosphate restriction and may progress to requiring phosphate binders
- Phosphate binders block P04 absorption in the intestine and should be taken with meals
- Three types of phosphate binders: aluminum-based, calcium-based, and aluminum-free, calcium-free drugs
- CKD disrupts Ca, P04, and vitamin D balance, leading to increased PTH, bone demineralization, and anemia
- Aluminum-based binders are potent but rarely used due to aluminum accumulation risk
- Calcium-based binders, first-line treatment, can cause hypercalcemia and constipation
- Aluminum-free, calcium-free binders are less likely to cause hypercalcemia but are more expensive
- Lanthanum carbonate and sevelamer are non-calcium, non-aluminum binders with specific considerations and side effects
- Phosphate binders have various drug interactions and should be administered with caution alongside other medications
- Sucroferric oxyhydroxide and ferric citrate are iron-based binders and have specific interaction considerations
- Lanthanum carbonate has interactions with aluminum-, calcium-, or magnesium-containing antacids and quinolone antibiotics
- Careful administration timing is crucial for avoiding interactions with levothyroxine and antibiotic medications

Managing Hyperkalemia and Metabolic Acidosis in Renal Disease
- Drugs that raise potassium levels include ACE inhibitors, heparin, aldosterone receptor antagonists, NSAIDs, and potassium-containing IV fluids.
- In severe hyperkalemia, the urgent clinical need is to stabilize myocardial cells and rapidly shift potassium intracellularly or induce elimination from the body.
- Medication options for hyperkalemia management include calcium gluconate, regular insulin, dextrose, sodium bicarbonate, albuterol, furosemide, sodium polystyrene sulfonate, patiromer, and sodium zirconium cyclosilicate.
- Calcium gluconate stabilizes myocardial cells to prevent arrhythmias but does not decrease potassium levels.
- Insulin, dextrose, and sodium bicarbonate are used to shift potassium intracellularly.
- Albuterol and furosemide stimulate potassium elimination.
- Sodium polystyrene sulfonate, patiromer, and sodium zirconium cyclosilicate bind potassium in the GI tract, with varying onset times and routes of administration.
- Drugs for treatment of hyperkalemia include sodium polystyrene sulfonate, patiromer, and sodium zirconium cyclosilicate, each with specific dosing, warnings, side effects, and monitoring requirements.
- Metabolic acidosis in renal disease can be treated with sodium bicarbonate or sodium citrate/citric acid solutions, with associated monitoring and precautions.
- Dialysis becomes necessary in stage 5 renal disease, with the two primary types being hemodialysis (HD) and peritoneal dialysis (PD).
- In hemodialysis, the patient's blood is pumped to a dialysis machine and runs through a semipermeable dialysis filter to remove waste products, electrolytes, and excess fluid.
- Drugs used for managing hyperkalemia and metabolic acidosis in renal disease have specific mechanisms, dosing, and monitoring requirements, and should be used with caution in the context of patient comorbidities and other medications.
Management of Secondary Hyperparathyroidism, Anemia, and Hyperkalemia in CKD
- Secondary hyperparathyroidism is treated with vitamin D analogs such as calcitriol, calcifediol, doxercalciferol, paricalcitol, and calcimimetic agents like cinacalcet and etelcalcetide, which help regulate calcium, phosphorus, and PTH levels.
- Treatment options for anemia of chronic kidney disease (CKD) include erythropoiesis-stimulating agents (ESAs) like epoetin alfa and darbepoetin alfa, which can prevent the need for blood transfusions, but have risks like elevated blood pressure and thrombosis.
- ESAs should be used cautiously when hemoglobin is less than 10 g/dL and discontinued if it exceeds 11 g/dL due to increased risk of thromboembolic disease.
- Adequate iron availability is crucial for the effectiveness of ESAs, and intravenous iron supplementation is often necessary in CKD patients, particularly in end-stage renal disease (ESRD) due to reduced GI absorption and blood loss from dialysis.
- Hyperkalemia, defined as potassium level > 5 mEq/L, is primarily caused by decreased renal excretion due to kidney failure, high dietary potassium intake, or drugs that interfere with potassium excretion, and is more prevalent in hospitalized patients and those with diabetes.
- Symptoms of hyperkalemia can include muscle weakness, bradycardia, and fatal arrhythmias, and the risk for severe outcomes increases with higher potassium levels.
- Management of hyperkalemia involves monitoring ECG, and treatment may include dietary restriction of potassium, discontinuation of potassium-sparing medications, use of potassium-lowering agents, or in severe cases, dialysis.
- Hyperkalemia can be asymptomatic, and patients with elevated potassium levels may require ECG monitoring to assess the risk of severe outcomes.
- The normal potassium level is 3.5 - 5 mEq/L, and hyperkalemia is concerning at any level above 5 mEq/L, with the most common cause being decreased renal excretion due to kidney failure.
- Renal potassium excretion is influenced by factors such as aldosterone, diuretics, urine flow, and negatively charged ions in the distal tubule, while insulin helps shift potassium into cells, offsetting acute rises in potassium from meals.
- Anemia in CKD is primarily due to reduced erythropoietin (EPO) production by the kidneys, leading to decreased hemoglobin levels and symptoms such as fatigue and pale skin, exacerbated by the inflammatory state of CKD.
- Anemia management involves ESAs to stimulate RBC production, which requires adequate iron availability, and IV iron supplementation may be necessary in ESRD patients due to reduced GI absorption and blood loss from dialysis
