Week 5 Diuretics / Reproductive cont. Flashcards
(34 cards)
Loop Diuretics (e.g. Furosemide. Bumetanide, Torsemide)
- work in ascending Loop of Henle - block reabsorption of sodium and chloride, preventing water reabsorption - promote rapid diuresis even in severe renal impairment
Loop Diuretics - Uses
- pulmonary edema - edema due to cardiac, liver or renal disease - hypertension - hypercalcemia
Loop Diuretics - Complications
- hyponatremia, hypochloremia - hypomagnesemia, hypokalemia - hypotension - ototoxicity - hyperglycemia, hyperuricemia, hypocalcemia, hypomagnesemia - decreased HDL - increased LDL & cholesterol levels
Loop Diuretics - Contraindications
- Digoxin - Lithium - ototoxic meds - NSAIDs - antihypertensives - pregnancy - anuria - caution with diabetes, cardiac disease, gout, dehydration or electrolyte issues
Thiazide Diuretics (HCTZ, end in thiazide, metolazone)
- promote diuresis when renal function is intact - block reabsorption of sodium & chloride and inhibits water reabsorption - work in distal tubule of kidney
Thiazide Diuretics - Use
- first line tx for essential hypertension - edema from mild to moderate liver or kidney impairment - often used with other blood pressure meds - promote reabsorption of calcium & reduce risk for osteoporosis in menopause
Thiazide Diuretics - Complications
- dehydration - hyponatremia, hypokalemia, hypochloremia, hypomagnesemia - hyperglycemia, hyperuricemia - increased LDL levels - NO ototoxicity risks
Thiazide Diuretics - Contraindications
- NO during pregnancy or breastfeeding - not for renal impairment - caution with diabetes, cardiac disease, gout, dehydration or electrolyte issues - use caution if patient is also taking: Digoxin, Lithium, ototoxic meds, NSAIDs, antihypertensives
Potassium Sparing Diuretics (e.g. Spironolactone, Triamterene, Amiloride)
- block aldosterone, resulting in potassium retention, but excretion of water & sodium
Potassium Sparing Diuretics - Uses
- combined with other diuretics for hypertension - heart failure - hyperaldosteronism - given orally
Potassium Sparing Diuretics - Complications
- hyperkalemia - endocrine: deep voice, impotence, irregular menses - drowsiness, metabolic acidosis
Potassium Sparing Diuretics - Interactions
- ACEs increase risk for hyperkalemia , as well as potassium supplements and salt substitutes
Osmotic Diuretics (Mannitol)
- intracranial emergency from edema -> increased intraocular pressures -> rapid shift of fluid into vessels promoting diuresis
Osmotic Diuretics - Complications
- heart failure - fluid overload - pulmonary edema - rebound increased intracranial pressure - fluid & electrolyte imbalance - metabolic acidosis
Osmotic Diuretics - Contraindications
- NOT for intracranial bleeds - anuria - severe pulmonary edema - dehydration - renal failure - pregnancy & lactation
Osmotic Diuretics - Interactions
- Lithium - Digoxin
Erythropoietic Drugs (e.g. Epoetin Alfa, Darbepoetin) - Use
- anemia due to CKD, anemia pre-surgery, HIV/AIDS anemia, anemia secondary to meds - stimulates bone marrow to produce red blood cell development
Erythropoietic Drugs - Complications
- hypertension - blood clot risk / MI / stroke / DVT - headaches, bone pain, muscle aches - NOT for pregnancy, hypertension or history of blood clots
Estrogens (Estradiol) - Use
- contraception - menopause - osteoporosis - abnormal bleeding - prostate cancer
Estrogens - Complications
- increased cancer risk - blood clots, especially with smoking - cautious use in cardiac patients - NOT for pregnancy / breastfeeding
Estrogens - Interactions
- decreases anticoagulants’ effectiveness - phenytoin decreases estrogen effects - decreases effectiveness of oral hypoglycemics and thyroid meds - increases steroid effectiveness
Androgens (Testosterone) - Use
- sperm maturation - increases sex development, skeletal muscle and synthesis of erythropoietin
Androgens (Testosterone) Use
- hypogonadism, delayed puberty - replacement for testicular failure - anemia unresponsive to other tx - breast cancer - muscle wasting during caner or AIDS
Androgens (Testosterone) - Complications
- facial hair, acne - irregular menses - deep voice - baldness - priapism, penile enlargement - reduction of height (epiphyseal plate) - hepatitis / jaundice - high cholesterol - prostate cancer - polycythemia - high potential for abuse - edema - hypercalcemia - hypoglycemia
