Study Notes
Drug Classes and Their Uses in Kidney Conditions
- Potassium Binders: Primarily used to treat hyperkalemia in patients with Chronic Kidney Disease (CKD).
- ACE Inhibitors: Known for reducing albuminuria in diabetic nephropathy and a first-line treatment for hypertension in CKD due to their benefits in lowering blood pressure and protecting renal function.
- Thiazolidinediones (TZDs): Common side effects include weight gain and edema, but do not typically cause hypoglycemia.
- SGLT2 Inhibitors: Work by reducing glucose reabsorption in the kidneys, beneficial in lowering blood glucose and protecting kidney function in diabetes management.
Complications and Effects Related to Diabetes and Hypertension
- Diabetic Neuropathy: A common complication associated with poorly controlled diabetes.
- Proteinuria in CKD: Effectively reduced by ACE inhibitors, which help in managing long-term kidney health.
- Poorly Controlled Hypertension: Associated with major complications like stroke and acute kidney injury in CKD patients.
Medications and Their Side Effects
- Lactic Acidosis Risk: Biguanides, particularly Metformin, are associated with this risk in patients with renal impairment.
- Hyperkalemia: Known side effect of potassium-sparing diuretics; should be monitored when used in patients with CKD.
- Common Causes of Intrinsic AKI: Nephrotoxic drugs are a leading cause, highlighting the need for careful medication management.
Other Important Concepts
- Prerenal Acute Kidney Injury (AKI): Characterized by decreased renal perfusion, which is crucial for diagnosis and management.
- Phosphate Binders: Medications primarily used to control hyperphosphatemia in CKD patients.
- 'Triple Whammy' Effect: Refers to the risk of acute kidney injury resulting from the combined use of NSAIDs, ACE inhibitors (or ARBs), and diuretics, necessitating careful medication management.
- GLP-1 Agonists in Diabetes: Provide benefits like weight loss, enhancing diabetes management.
Key Mechanisms of Action
- DPP-4 Inhibitors: Increase levels of incretin hormones, regulating insulin secretion and lowering glucagon release to manage blood glucose levels effectively.
- ACE Inhibitors in Diabetic Nephropathy: Lower blood pressure and decrease proteinuria, thus slowing disease progression and protecting kidney function.
- SGLT2 Inhibitors: Lower blood glucose levels while also reducing intraglomerular pressure, which helps in protecting renal function in CKD management.
