Enalapril × Valsartan
Angiotensin-converting enzyme inhibitors (ACEi)×Angiotensin II receptor blockers (ARBs)
Mechanism
Dual RAAS blockade (ACE-I + ARB). Proven in ONTARGET and VA NEPHRON-D trials: increased hyperkalaemia, hypotension, and acute kidney injury without cardioprotection.
Symptoms
Muscle weakness, paraesthesia, slowed pulse, arrhythmias. ECG: peaked T waves, widened QRS. Severe cases progress to cardiac arrest.
Management
The combination is not prescribed. Choose one: ACE-I (enalapril) if tolerated, ARB (valsartan) if there is a dry cough or intolerance.
