Pharm 2 Flashcards
Criteria for HTN
SBP +130
DBP +80
Taking Anti-HTN med
ISH criteria
SBP +140 and DBP -90
Humoral factors of TPR
Constrictors: Catecholamine Angiotensin 2 Thromboxanes Leukotrienes Endothelin
Dilator:
Prostaglandin
Kinin
NO
Definitional function of Diuretic
Lower BP by depleting body of Na and reducing volume
Definitional function of Anti-adrenergic Agent
Inhibits cardiac function (dec CO) Reduce PVR (dec CO) Increase venous pooling
Definitional function of Direct Vasodilators
Reduce BP by relaxing SM and dilate PVR
Definitional function of blocking production/action of angiotensin?
Reduce PVR and blood volume
Where do Acetazolamide elicit it’s function on the kidney?
Between glomerulus and PCT
Where do Osmotic Diuretics (Mannitol) elicit it’s function on the kidney?
Descending LoH
Where do Loop Diuretics (Furosemide) elicit it’s function on the kidney?
Ascending LoH
Where do K Spring elicit it’s function on the kidney?
CD
What has been shown to be the best tolerated HTN treatment class?
Diuretics
Diuretics are more effective at reducing BP when combined with?
ACEI
ARB
ACEIs reduce Angiotensin 2 which then causes a reduction in what five things?
HANAS Vascular SM Aldosterone synthesis/release Na reabsorption HR ADH release
Where is bradykinin found?
It is involved in the production of what two dilators?
Lungs
Smooth muscles
Blood vessels
NO and prostaglandins
ACEIs are used with PTs that have what five compelling indicators?
SC PHD
DM w/ protein Post MI HF Stroke Hx High CAD risk
ACEIs have reduced efficacy in African Americans but can become equally for all races/ethnicity efficient when combined with ?
CCB
Diuretic
What are the three clinical features/uses of ACEIs?
HTN
AfAm HTN
Renal insufficiency, reduces glomerular pressure
What is the Renal Trifecta of ACEIs?
Diuretics- inc Scr
NSAIDs- inc constriction in afferent arteriole
ACEI/ARBs- dilates efferent arteriole
Big two different side effects of DRI than other HTN meds?
Diarrhea
Sulfonamide component
DRI interactions include what 3?
ARB/ACEI
NSAID
Lithium
A1s are not used for monotherapy or first step therapy but can be combined with?
Diuretic
BB
ACEIs
Three big side effects of A1 blockers?
First dose syncope
Reflex tachycardia
Inhibited ejaculation
Which A1 blocker is more likely to cause edema in the PT and should be given with a diuretic?
Prazosin
