Anti-Hypertensive Medications

Introduction

  • Presenter: Christine from Nurse in the Making
  • Content: Overview of anti-hypertensive medications
  • Purpose: Lower blood pressure, manage chronic hypertension, decrease heart workload

Understanding Anti-Hypertensives

  • Definition: Medications that lower high blood pressure
  • Mechanism: Different groups with varying mechanisms but same goal - lower blood pressure

Mnemonic: As Easy as A B C D

A: ACE Inhibitors

  • Function: Inhibit Angiotensin converting enzyme
    • Prevent conversion from Angiotensin I to Angiotensin II
    • Keep vessels dilated, lower blood pressure
    • Prevent aldosterone secretion (retains water & sodium)
  • Medication Suffix: -pril (e.g., enalapril, lacinopril, captopril)
  • Side Effects (ACE):
    • A: Angioedema (dangerous swelling of lips, eyes, face)
    • C: Cough (dry, common, not dangerous)
    • E: Elevated potassium levels (dangerous)

ARBs (Angiotensin II Receptor Blockers)

  • Function: Block Angiotensin II receptors
    • Prevent vessels constriction
  • Medication Suffix: -sartan (e.g., candesartan, losartan, valsartan)
  • Notes:
    • Similar side effects as ACE inhibitors
    • Less likelihood of cough or angioedema

B: Beta Blockers

  • Function: Block beta 1 receptors
    • Reduce sympathetic nervous system effects
    • Lower heart rate and blood pressure
  • Medication Suffix: -olol (e.g., metoprolol, propanolol, carvedilol)
  • Side Effects (Bs):
    • Bradycardia and heart blocks
    • Breathing problems (bronchospasms)
    • Bad for acute heart failure
    • Blood sugar masking (hypoglycemia symptoms hidden)
    • Blood pressure lowered (risk of hypotension)

C: Calcium Channel Blockers

  • Function: Block calcium movement, relax heart contraction
    • Lower heart rate and blood pressure
  • Medication Mnemonic: Very Nice Drugs
    • V: Verapamil
    • N: Nifedipine
    • D: Diltiazem

D: Diuretics and Digoxin

  • Note: Covered in a different video

Nursing Considerations

  • Monitor for:
    • Hypotension and orthostatic hypotension (dizziness upon position change)
    • Electrolyte levels: potassium and sodium
  • Patient Education:
    • Report muscle cramps, weakness, rapid heart rate
    • Assess for angioedema (especially with ACE inhibitors)
    • Do not stop medication suddenly to avoid rebound hypertension
    • Taper off medication (prevent sudden blood pressure increase)
