Study Notes
Thiazide Overview
- Thiazide diuretics cause hypokalemia (low potassium), hyponatremia (low sodium), and may lead to hypercalcemia (high calcium).
- Common drug names include Microzide and Zarolyxn.
Side Effects of Thiazide
- Patients may experience postural hypotension, vertigo, headache, fatigue, muscle weakness, and general weakness and lethargy.
- Gastrointestinal reactions such as anorexia, nausea, and vomiting are also noteworthy.
- Skin conditions can arise, including rash, photosensitivity, hyperglycemia, and elevated uric acid levels.
Treatment Indications
- Thiazides are effective for treating heart failure, edema, and cirrhosis.
- Used to manage hypertension by reducing peripheral vascular resistance and fluid retention.
- Serve as prophylaxis for kidney stones.
Nursing Interventions
- Administer thiazides with food to minimize gastric irritation.
- Schedule doses in the morning to avoid sleep disruption and educate patients to rise slowly to reduce postural hypotension risks.
- Monitor patients regularly for persistent side effects and conduct blood tests to check electrolyte levels.
Cautions and Contraindications
- Use cautiously in patients with diabetes, hyperglycemia, or a history of gout.
- Contraindicated in individuals with severe renal disease or impaired liver function.
- Older adults may exhibit greater sensitivity and susceptibility to low sodium levels.
Mechanism and Action
- Thiazides promote urine production by increasing the secretion of water, sodium, chloride, and potassium.
Potassium-Sparing Diuretics
- Indicated when potassium depletion is a concern; examples include spironolactone and triamterene.
- Utilized alongside thiazides to enhance diuretic effects while reducing the risk of hyperkalemia.
- Monitor serum potassium levels regularly.
Side Effects of Potassium-Sparing Diuretics
- Potential for hyperkalemia, dehydration, and GI symptoms such as nausea and vomiting.
- Patients may experience fatigue, lethargy, and hypotension, alongside side effects like profound weight loss and gynecomastia.
Drug Interactions
- Digoxin: Risk of toxicity when thiazides are used.
- Corticosteroids: May increase potassium levels.
- Lithium: Increased risk of intoxication with concurrent thiazide use.
- NSAIDs: Can lead to renal failure and reduce blood pressure control.
- Antidiabetic agents: Thiazides may lead to loss of diabetic control.
Loop Diuretics Overview
- Act directly on the loop of Henle, blocking sodium and chloride reabsorption, leading to increased urine production.
- Common drugs include furosemide, bumetanide, and torsemide.
Side Effects and Treatment
- Loop diuretics can cause dehydration, electrolyte imbalances (hypokalemia, hypocalcemia), and hypotension.
- Indicated for edema related to renal function impairment, heart failure, liver disease, and conditions like pulmonary edema.
