What drug class is Valsartan
A. ARBS
B. BB
C. CBB
D. Anticholesterol
A. ARBS
What is the action of Valsartan
Valsartan
Action
Inhibits binding of angiotensin II to its
receptor
Inhibits angiotensin II (no vasoconstriction)
and inhibits the release of aldosterone
(release sodium and water – hold on to
potassium
Uses
Hypertension
Heart failure
Angiotensin II Receptor Blockers
(ARBs) – end in ‘sartan’ or ‘tan’
Side effects of ARBS
Side Effects/adverse reactions
DOES NOT cause the cough of ACEI
Dizzy, drowsy, fatigue
Insomnia, headache
Erectile dysfunction
Adverse effects of ARBS
Orthostatic hypotension
Hyperkalemia
Hypotension
Renal dysfunction
Contraindication of ARBS
Contraindications
Pregnancy
Lactating
Interactions
Other anti-hypertensives
Alcohol
NSAIDS can increase renal dysfunction/hyperkalemia
OTC cold medicine
pt teaching antihypertensives
Teaching
Take blood pressure and pulse daily and what to report
Weigh daily report weight gain over 2 pounds in one
day, 5 pounds in one week
Get up slowly
Do not stop antihypertensives abruptly
Check with HCP before taking OTC meds (especially
cold medicine)
Beta blockers – teach diabetic patient interactions
ACEI and A2RB – teach no salt substitute with K, low
K diet, no K supplements
Nursing process – anti-hypertensives
Nursing intervention Antihypertensives
Nursing interventions
Monitor vital signs including heart rate on beta blockers
and calcium channel blockers
Monitor for signs and symptoms of electrolyte
imbalance with ACEI, A2RB
Alpha and beta blockers can take several weeks for full
effects
Monitor for peripheral edema with alpha & beta
blockers and calcium channel blockers
Too big of a drop in BP should be reported
Nursing process – anti-hypertensives
