Drug Interaction:
ACE inhibitors include- Benazepril, Captopril, Enalapril, Enalaprilat, Fosinopril, Lisonopril, Moexipril,Perindopril, Quinapril, Ramipril, Trandolapril
Refer Captopril
Interacting drugs
Spironolactone
Rifampicin
ACE inhibitors with
Spirinolactone
use of ACE inhibitors may elevate serum potassium. Concurent use with spirtonolactone may lead to significant hyperkalemia
Rifampicin
pharmacologic effects of enalapril may be decreased
Risk of bone marrow supression increased with concomittant treatment with immunosupressive drugs(cyclophosphamide,azotripine),
Hypokalemia with Pot sparing diuretics or Potassium supplements especially in the presence of renal failure. Probenicid delays excretion Potentiates analgesia and respiratory depression produced by morphine.
NSAIDs blunt its hypotensive effect.
Diuretics potentiates hypotensive effect but the starting dosage of Enapril must be kept low.
May increase lithium levels.
