Week 5 Diuretics / Reproductive cont. Flashcards
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
Androgens (Testosterone) - Contraindications
- NOT for pregnancy - breast or prostate cancer - severe cardiac, liver or kidney disease - caution with CHF, hypercalcemia or hypertension
Androgens (Testosterone) - Interactions
- alters anticoagulants - affects insulin & oral antidiabetic drugs - increased risk for hepatotoxicity
SERMS (Selective Estrogen Receptor Modulators), e.g. Raloxifene
- used for osteoporosis & breast cancer - controls bone loss, high cholesterol and coagulation
SERMS (Selective Estrogen Receptor Modulators), e.g. Raloxifene - Complications
- DVTs - hot flashes - not for pregnancy or history of DVTs - 3 days before risk of blood clot (travel, surgery) - do NOT use with other estrogens
5-Alpha Reductase Inhibitors (e.g. Finesteride, Minoxidil)
- decreases testosterone, shrinks prostate and grows hair - used for BPH & male pattern baldness
5-Alpha Reductase Inhibitors (e.g. Finesteride, Minoxidil) - Complications
- decreased libido - gynecomastia - not for pregnancy or liver disease - DO NOT handle if pregnant or planning to become pregnant
Alpha Blockers
- end in osin or zosin - vasodilator - used for BPH, urinary retention or frequency - complications: hypotension, dizziness, nasal congestion - not for liver failure or renal impairment - interacts with GI meds, ED drugs & nitrates
Biphosphonates (e.g. Aldendronate)
- decreases bone loss - treats osteoporosis, Paget’s disease - risks: esophageal erosion / ulcers, GI upset, bone pain, vision changes, osteonecrosis of the jaw, kidney toxicity - interacts with calcium, iron, antacids, orange juice and caffeine - special instructions: must sit upright at least 30 - 60 minutes - take on empty stomach - drink at least 8 oz of fluid after - wait 30 minutes to take other meds
Calcitonin (Calcitonin Salmon)
- inhibits osteoclasts in osteoporosis - treats osteoporosis and Paget’s - complications: nausea, dry nose or nasal irritation - NOT for pregnancy, allergy to salmon or fish - interacts with lithium - eat high calcium diet - alternate nostrils, store in fridge
Phosphate Binders (e.g. Reangle, Renville, Phoslo)
- Phosphorus Binders (also called phosphate binders) prevent the body from absorbing phosphorus and help to pass excess phosphorus out of the body in the stool, reducing the amount of phosphorus that gets into the blood - usually phosphate binders are taken within 5 - 10 minutes before or with meals - normal phosphorus level is 3.0 - 5.5
