35
When should one begin treating HTN?
1. IF DM or CKD + > 140/90 mmHg - IMMEDIATELY 2. IF Stage 2 HTN (>160 or >100 mmHg) - 2 drug regimen

38
What are the actions of Diuretics?
1. REDUCES plasma volume and thus chronically reduces peripheral resistance. * FIRST LINE TX ESSENTIAL HTN - Thiazide Diuretics (GOLD) - Loop Diuretics (IF renal dysfunction or with close electrolyte monitoring) * May require K supplementation
39
What are the actions of Beta Blockers?
1. REDUCES HR and Cardiac Output * BEST FOR WHITES *IF B/P to high and you can't get it down then ask the patient if they have taken their BP medication today?
40
In what patients are Beta Blockers best to use with HTN?
Post MI or with CHF *Reduces morbidity *Carvedilol > Metoprolol in reducing the HR with CHF patients.
41
When should you use caution with Beta Blockers?
1. Pulmonary disease (May trigger pulmonary conditions) 2. Diabetes Mellitus (May disguise true hyperglycemia) *Most cardio-selective beta blocker should be used
42
What is the order of least cardio-selective - most cardio-selective beta blockers?
Propanolol > Carvedilol > Etanolol > Metoprolol > Nebevilol "Bystolic"
43
What are the actions of ACE-Inhibitors?
INHIBIT bradykinin degradation (INCREASES bradykinin) + INCREASES synthesis of vasodilators (Prostaglandins) by inhibiting ACE (Angiotensin Converting Enzyme) *STOPS the reduction of bradykinins which increases prostaglandins, which are vasodilators, thus ACE-I aid in vasodilation
44
What patients are ACE-I best to use with?
IF: - HTN + (DM + CKD) * These help to preserve the kidney function, thus it is imperative to place patient on if you see any signs of kidney damage - HTN (Mild-Mod) + Young white person where a diuretic hasn't worked - Post MI/CHF (Second to Beta Blockers)
45
What is the greatest S/E of ACE-I?
Cough
46
What are the action's of ARB's (Angiotensin Receptor Blockers)?
-They block the interaction of Angiotensin 2 receptors and they works similar to ACE-I without the inhibition of Bradykinin, thus NO COUGH
47
What patients are ARB's best to use with?
-DM + CKD (They preserve the kidney function and thus they should be used if the ACE-I cough is retractable).
48
What are the actions of Calcium Channel Blockers?
-Peripheral vasodilation
49
What are the patients that are best to use Calcium Channel Blockers on?
-Blacks and Elderly
50
Whats the drug used for HTN as an Aldosterone Receptor Antagonist?
- Spironolactone | * Best to use if refractory HTN. but as an adjunct
51
When is it best to use spironolactone?
-As an adjunct with Beta Blockers or ACE-I/ARB's in patients who are post MI/CHF
52
What is the action of Alpha Adrenergic Antagonists?
-They DECREASE peripheral vascular resistance
53
What patients are Alpha Adrenergic Antagonists best to use with?
-MEN with symptoms of BPH
54
How to treat HTN urgencies or emergencies?
- Parenteral agents: | * DON'T reduce HTN too fast = Cerebral Ischemia
55

Dopamine-1 receptor Agonist "Fenoldopam"
58
What's the best Anti-HTN with pregnancy?
1. Hydralazine "Apresoline" 2. Methyldopa "Aldomet" * Methyldopa ensure you use caution when breast feeding as this is passed via the breast milk.
59
What are the drugs with the class of Diuretics?

61
What are the side effects of loop Diuretics?

62
Mnemonic for remembering the diuretics?
Leak Over The CAN -Loop diuretics / Osmotics / Thiazides and Thiazide like / Carbonic Anhydrase Inhibitors / Aldosterone Inhibitors / Na Channel Blockers
63

1. Dizziness / Lightheadedness / Headache 2. Blurred vision 3. Loss of appetite / Nausea 4. Itching / Rash (SLE like) 5. Electrolyte Abnormalities: a. Hypokalemia (Low K) b. Hypomagnesemia (Low Mg) c. Hyponatremia (Low Na) d. Hypercalcemia (High Ca) 6. Hyperuricemia (Increased risk of gout from uric acid) 7. Hyperlipidemia
65
What drugs are in the class of potassium sparing diuretics?
1. Amiloride (Midamore) 2. Spironolactone (Aldactone) 3. Triamterene (Dyrenium)
