Enalapril (Vasotec) is an Antihypertensive agent that belongs to a class of drugs known as angiotensin-converting enzyme inhibitors (ACE-inhibitors).Enalapril is rapidly converted to its active metabolite, Enalaprilat, by hepatic biotransformation.
Generic name | Enalapril |
Brand name | Vasotec, Innovace |
Drug class | Angiotensin-converting enzyme inhibitors |
Drug group | Antihypertensive, Vasodilator |
This agent is a vasodilator that is used to treat high blood pressure and heart failure. Enalapril is sold under the brand name Vasotec, it is available as oral tablets, powder for oral solution and injection solution.
Maleate salt of Enalapril is called Enalapril maleate, it is also available as combinations with diuretics such as:
Enalapril maleate/ hydrochlorothiazide (Vaseretic).
Enalaprilat which is the active metabolite of Enalapril (Vasotec), acts by inhibiting the action of the ACE, this inhibition will prevent the conversion of angiotensin I to angiotensin II (a potent vasoconstrictor). Reduced angiotensin II levels result in the reduction of aldosterone secretion, which reduces sodium and water reabsorption, this will lead to decreased peripheral resistance and blood pressure.
Enalapril (Vasotec) is used in the treatment of:
- Hypertension (high blood pressure)
- Symptomatic heart failure

Several drugs and substances can interact with Enalapril resulting in undesired effects. Interaction can affect the activity of the drug and the severity of its side effects.
Interactions with drugs
Enalapril can form drug-drug interactions with the following drugs:
Potassium-sparing diuretics and potassium supplements:
the effect of these drugs is enhanced by Enalapril, leading to an increase level of potassium in the blood.
Non-steroidal anti-inflammatory drugs (NSAIDs):
Enalapril effectiveness is reduced when used with these drugs. There is also an increased risk of acute renal failure.
Diuretics and other anti-hypertensive agents:
these drugs increase the blood pressure-lowering effect of Enalapril.
Lithium
Enalapril increases lithium concentration in the blood, leading to toxicity.
Interactions with Herbal medicines:
Ginseng, yohimbe and ephedra may make hypertension worse.
Garlic can increase the antihypertensive effect of Enalapril.
Licorice can cause sodium and water retention leading to additive hypertensive effects.
