| adverse effects of ACEI and ARBs |
|
Definition
hypotension w first dose (bc they have overactive RAS systems- very high levels of circulating renin and angiotensin II), monitor for 1st 30 min, hyperkalemia (interfere w downstream aldosterone reabsorption), elevations in creatinine (prevent angiotensin II's affect) but renal protective over time
ACEI- can cause dry cough (breaks down bradykinin which can irritate the throat)- switch to ARB
-most severe side effect of these medications is angioedema bc of effect on bradykinin (laryngeal vasodilator), tongue can swell- discontinue (10 fold higher risk of this in African Americans), counsel pts to call 911 or present to ER |
|
|
Term
| direct renin inhibitor agent, MOA, adverse effects |
|
Definition
aliskiren (Alaskan), It's mechanism is to directly block the release of renin from the adrenal medulla and delaying the ability for renin to be released from the adrenal medulla prevents downstream formation of ACE conversion to angiotensin II. Again, overall, this decreases afterload, just like the ACEs and ARBs, which works to lower systemic vascular resistance, and therefore lower blood pressure
Adverse effects- diarrhea, hyperkalemia |

Term
| Intrinsic Sympathomimetic Activity |
|
Definition
| a beta blocker has ISA if it acts as a partial agonist at the beta 1 receptor (a minimally effective agonist, so ineffective that it blocks adrenaline from doing its job and activating beta 1- ceiling effect- prevents bradycardia)-- so acebuterol may be a good agent for someone w a resting HR of 50-60 bc it would prevent brandycardia. most nonselective beta blockers are rarely used for HTN or cardiac conditions, ex timolol eye drop medication is used for glaucoma and intraocular HTN, nadolol and propanolol are used for performance anxiety |

|
|
Term
|
Definition
| common in pts who are HTN, due to anti-diuretic hormones' resistance that's endogenous in patients. The symptoms include polyuria, hypernatremia, and hypovolemia. Often, hypercalcemia is one of the precipitating factors in diabetes insipidus. So use of loop diuretics is not advised.. treat w low salt and low protein diets, thiazide and K-sparing diuretics are preferred , NSAIDS are useful, may need exogenous anti-diuretic, DDVAP (analog of anti-diuretic, it reverses the resistance to anti-diuretic hormone because it is chemically modified to agonize the receptor with a much higher affinity) it also is used for prevention of bleeding, in patients with uremia or nocturia to prevent overnight urination. SE: hyponatremia, water intoxication, as well as headache, allergies |
