Q

Describe the rationale for polypharmacy tx of HTN

A
  1. The rationale behind polypharmacy is that each of the drugs acts on one of a set of interacting, mutually compensatory regulatory mechanisms for maintaining blood pressure
  2. Additional rationale is minimal toxicity: Two or three drugs at half standard doses might have greater efficacy and less toxicity than one drug at standard or twice standard dose

Diuretic If you do not understand, just memorize.
29
What are four drug classes that would make a hyperkalemic patient worse?
Aldosterone antagonist ACEi ARB Renin inhibitor I would think that sodium channel blockers would be here also, but they were not listed in up to date.

31
What are three HTN drug classes that may have adverse effects on renovascular disease?
ACEi ARB Renin inhibitor
32
What is a common choice of drug (specific) for combination with loop agents?
Metolazone
33
Combination of Thiazides and loop diuretics is not recommended for outpatient use because?
Cause profuse diuresis, and extreme potassium wasting
34
Combining K+ sparing diuretics with loop agents or thiazides can be highly efficacious, but this combination should be avoided in what two categories of patients?
1. Those with renal insufficiency 2. Those who are recieving angiotensin antagonists
35
Name three combinations involving anthypertensives that are to be avoided!
1. ACE inhibitors, ARBs, and renin inhibitors (only one at a time) 2. Beta-blockers and non-dihydropyridine CCBs 3. Potassium-sparing diuretics and ACE inhibitors/ARBs/renin inhibitors
36
What defines a hypertensive urgency?
\>180/120 **_without_** acute end organ damage
37
What definces hypertensive emergency?
\>180/120 **_with_** acute end organ damage
38
In general, what are the reduction goals for the first hour and the next 23 hours for hypertensive emergencies?
* 10-20% in the first hour * Further 5-15 percent over next 23 hours
39
How are the drugs used in hypertensive emergencies administered?
IV
40
What are the seven vasodilators used for tx of hypertensive emergencies?
1. Sodium nitroprusside 2. Nitroglycerine 3. Nicardipine 4. Clevidipine 5. Enalaprilat 6. Fenoldopam 7. Hydralazine
41
What is considered the most effective parenteral drug for HTN emergencies? What limits prolonged use?
Sodium nitroprusside Potential for cyanide toxicity
42
Nitroglycerine has less antiHTN efficacy than any other agent for HTN emergencies. Who is it useful for?
Adjuct therapy in patients with cardiac ischemia or after coronary bypass surgery
43
Nicardipine has a long onset of action and longer elimination half life. What is it's safety profile like?
Good.
44
What is clevidipine used for?
As an ultrashort acting DHP-CCB it is approced only for HTN emergencies
45
Enaliprilat is rarely used for HTN emergencies, due to slow onset and long duration of action. Characterize the hypotensive response.
Unpredictable, and dependent on plasma volume and renin activity
46
In what patients should fenoldopam be avoided?
Those with glaucoma
47
What limits the parental use of hydralazine? In what patients is this particularly useful?
Limited by prolonged and unpredicatable hypotensive effect. Very useful for pregnant patients

1. ACE inhibitors 2. ARBs 3. Direct Renin inhibitors 4. Nitroprusside
57
What do ace inhibitors, arbs and renin inhibitors do in pregnancy?
Associated with significant fetal renal and cardiac abnormalities
58
What does nitroprusside do in pregnancy?
Possible fetal cyanide poisoning if used for more than a few hours. Last resort for ugent control of severe refractory HTN
59
A common use for diuretics is for the reduction of peripheral or pulmonary edema that has accumulated as a result of cardiac, renal, or vascular diseases that reduce blood delivery to the kidney Physiologically, this reduction is sensed as a lack of effective arterial blood volume and leads to salt and water retention, followed by edema formation. What are examples of edemetous states that are treated with loop diuretics?
1. Heart failure 2. Kidney Disease 3. Hepatic Cirrhosis
60
What drugs are beneficial for individuals that develop hyperkalemia associated with early stage renal failure?
Thiazides and Loop diuretics
61
List four nonedematous states that are treated with diuretics.

62
What diuretics are useful in treatment of nephrolithiasis?
Thiazides d/t calcium reuptake Loop diuretics to flush stones out
63
What diuretics are useful in treating patients with hypercalcemia?
Loop diuretics, but should administer with saline to maintain effective Ca++ diuresis and prevent marked volume contration.
64
What would you use to treat diabetes insipidus?
Supplementary ADH or an analog would be effective in central diabetes insipidus. Thiazide diuretics can be used to reduce polyuria and polydipsia in both types of diabetes insipidus.
