“-startan”
Angiotensin II Receptor Blockers Therapeutic Actions
• Angiotensin II receptor agonist
• Blocks angiotensin II from binding with on the receptors on the vascular smooth muscle and in the adrenal cortex
- Prevents vasoconstriction
- Prevents release of aldosterone (sodium and water excreted)
Angiotensin II Receptor Blockers Indications
- HTN
- CHF
- Diabetic nephropathy
Angiotensin II Receptor Blockers Contraindications and Cautions
Contraindication:
• Allergy
• Pregnancy- black box warning
Caution:
• Hepatic dysfunction
• Renal dysfunction
• Hypovolemia (liquid portion of blood is too low)
Angiotensin II Receptor Blockers DDI
- Other drugs affecting RAAS
* NSAIDs
Angiotensin II Receptor Blockers Adverse Effects
- CNS: HA, dizziness, syncope, weakness
- CV: hypotension
- GI complaints
- Skin: rash
- Hyperkalemia
- Renal damage
Angiotensin II Receptor Blockers:
Assessment
Hx: allergy, contra/cautions, pregnancy, liver impairment
Physical: vital signs, weight, cardiac respiratory, abdominal, skin (baseline)
Labs: renal functions, electrolytes, pregnancy test, liver function
Angiotensin II Receptor Blockers:
Diagnosis
- Ineffective tissue perfusion
- Impaired skin integrity
- Acute pain
- Deficient knowledge
Angiotensin II Receptor Blockers:
Implications
- Encourage lifestyle changes
- Can take with or without food, if GI effects give with food
- Use of barrier contraceptives
- Monitor the patient carefully in any situation that might lead to a drop in fluid volume
- Provide throughout patient teaching
