10/22 Flashcards
pharm therapy
1st line: thiazides, ACE/ARB/renin inhibitors, CCBs
2nd line: loops, K sparing diuretics, BB, vasodilators (hydrazaline), alpha blockers
initial selection: potentially favorable effects in other disease states
diuretics
- roles in managing fluid: correct underlying disease state, restrict Na intake, administration
- most pts require >2 agents: a thiazide duiretic may be 1 unless CI, combo regimens often include a diuretic, resistant HTN: failure to achieve BP goal on full doses of 3 drug regimen including a diuretic
diuretics clinical indication
HTN, edema, CHF, CKD, hypercalcemia, diabetes insipidus
may slow osteoporosis
thiazide diuretics historically..
first line for most HTN pts
more effective than loops unless CrCl
thiazide AEs
hypokalemia, hypomagnesemia, hypercalcemia, hyperuricemia, hyperglycemia, hyperlipidemia, sexual dysfunction
lithium toxicity w concurrent admin
CI: sulfa allergy
thiazide examples
HCTZ, chlorthalidone, chlorothiazide, indipamide, metolazone
loop diuretics
dose in AM or afternoon to avoid nocturnal diuresis, higher doses may be needed in pts w severely dcreased GFR or HF (use in place of thiazides when CrCl
loop diuretics AEs
hypokalemia, hypomagnesemia, hypocalcemia, hyperuricemia, ototoxicity
CI: sulfa allergy (except ethacrynic acid)
K sparing diuretic examples
amiloride, triamterene
K sparing diuretics
weak diuretics, generally used in combo w thiazide to minimize hypokalemia
K sparing diuretics AE
hyperkalemia (especially w ACE/ARB or K supplements), avoid in pts w CKD or DM
aldosterone antagonists examples
spironolactone, eplerenone
aldosterone antagonists CI
due to inc hyperkalemia, eplerenone is CrCl
aldosterone antagonists AE
hyperkalemia (especially w ACE/ARB or K supplements
avoid in CKD or DM
gynecomastia: up to 10% of patients taking spironolactone
ACE clinical indications
HTN, left ventricular systolic dysfuction, MI, diabetic nephropathy, renal artery stenosis (degree of stenosis)
