Neprilysin inhibitor / ARB
Combo drug
Sacubitril/valsartan Entresto
Neprilysin is an enzyme that contributes to the breakdown of the biologically active natriuretic peptides. By blocking the enzyme we increase our endogenous ANP, BNP, and CNP
alpha1, alpha 2 antagonist Not used for long term treatment
phentolamine
Hypos - calc, mag, K, H = met. alkalosis, ototoxicity (avoid aminogylcosides)
furosemide
Treat Severe pulmonary arterial HTN
bosentan
Endothelin (ET) receptor antagonist
ambrisentan
HF with renal dysfunction who cannot tolerate ACEI. HTN emergencies in pregnancy
hydralazine
Dilation of coronary arteries, systemic (peripheral) arterioles
Dihydropyridine - bind to inactivated L-type
nifedipine
amlodipine
Aldosterone/mineralocorticoid receptor antagonist - potassium sparing metabolized by liver
spironolactone
alpha1, alpha 2 antagonist Irreversible
phenoxybenzamine
Teratogenic, Hyperkalemia
ARBs
Decreases systemic vascular resistance AND Na absorption by the kidney (by blocking formation of ATII)
aliskiren tekturna
No effect on bradykinin - minimal incidence of cough and angioedema. K sparing diuretics contraindicated
ARBs
Natriuretic peptide 6 actions
promote vasodilation
relax smooth muscle
increased capillary endothelial permeability
promote natriuresis increased renal Na excretion
promote increase in GFR
suppress SNS outflow
ARB what channel?
What type of receptor is it?
AT1
GQ
diuretic that leads to
Hyperglycemia, hypokalemia, metabolic alkalosis
Hydrochlorothiaze
Low dose - D1 - vasodilation, decreased SVR (afterload), increases renal blood flow and ANP/BNP; intermediate dose - Beta1 - increased contractility and HR; high dose - alpha1 - vasoconstriction
dopamine
longer half life than prazosin
terazosin
doxazosin
Hyperkalemia, met. Acidosis. Blocks androgen receptors (impotence and gynecomastia)
spironolactone
Initial treatment of HTN
propranolol
metoprolol
atenolol
Pro-drug - metabolized to release NO in the body. Requires mitochondrial aldehyde dehydrogenase (ALDH2) (sometimes missing in Chinese population)
nitroglycerin, glyceryl trinitrate
isosorbide dinitrate
isosorbide 5-mononitrate
Ventricular arrhythmias, thrombocytopenia (low blood platelet count)
milrinone
Prolong NMB, headache, dizziness, Peripheral edema, negative chronotropy/inotropy, overdose pulmonary edema
CCB
Renin inhibitor
aliskiren Tekturna
eNOS inhibitor
methylene blue
Short term severely decompensated HF and severely failing circulation. Bridge to cardiac transplantation
milrinone
Reversible lupus erythematosus-like syndrome (primarily in slow acetylators)
hydralazine
MAO and dopamine B-hydroxylase (caution in patients with MAOIs)
dopamine
Reduces systemic vascular resistance (afterload), increases RENAL blood flow
fenoldopam corlopam D1 agonist
