Enalaprilat is a type of medication known as an angiotensin-converting enzyme (ACE) inhibitor. It's used to treat high blood pressure in adults who can't take medications by mouth. In particular, the medication is typically used for people in the hospital who need their blood pressure lowered quickly. Enalaprilat is given as an injection into the veins as often as every 6 hours. Side effects include low blood pressure and dizziness.
Enalaprilat is an angiotensin-converting enzyme (ACE) inhibitor. ACE is a protein in your body that works to squeeze your blood vessels and help your blood pressure go up. Enalaprilat blocks how ACE works. This helps relax your blood vessels to lower blood pressure.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

Enalaprilat usually starts to work within 15 to 30 minutes. But it might take up to 4 hours until you see the most blood pressure-lowering effect from the medication.
It's possible for you to get a cough from taking enalaprilat. Dry cough is a well-known side effect of ACE-inhibitors like enalaprilat. This side effect can appear at any time during treatment. Tell your provider if you're coughing. Your provider might decide to stop enalaprilat and choose a different blood pressure medication for you. In general, the coughing should go away after you stop enalaprilat.
It's possible for enalaprilat to lower your heart rate. In a study with people with severely high blood pressure, heart rate dropped by an average of 20 beats per minute within 3 hours of taking enalaprilat. Your provider will check your heart rate along with your blood pressure before, during, and after treatment with enalaprilat.
Enalaprilat is very closely related to enalapril, but not exactly the same thing. Enalapril is a prodrug of enalaprilat. This means that when you take enalapril by mouth, your body needs to turn it into its active form, enalaprilat, for it to work to lower blood pressure. Enalaprilat is the injectable version of enalapril and is already in the active form. Enalaprilat is a good choice for people in the hospital who have severely high blood pressure and need to lower it fast.
No, enalaprilat isn't a beta blocker. Instead, enalaprilat is a medication known as an ACE inhibitor. Beta blockers and ACE inhibitors help lower blood pressure in different ways. Your provider might decide to treat you with a beta blocker along with enalaprilat, depending on how well your blood pressure improves with enalaprilat by itself.
Enalaprilat can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Enalaprilat can cause severe and sometimes life-threatening harm to unborn babies. For this reason, avoid using enalaprilat during pregnancy. Be sure your providers know if you might be pregnant before you get treated with this medication so they can consider using a safer medication to help lower your blood pressure.
People who take ACE inhibitors, like enalaprilat, can experience a rare, but serious side effect called angioedema. This involves swelling in different parts of the body, including the face, throat, and tongue. Swelling of the tongue or throat area can be potentially life-threatening since it can make it difficult to breathe. Angioedema can happen at any time during treatment. You might be more likely to experience angioedema if you're Black, an older adult, or of female sex. Get medical help as soon as possible if you notice any unusual swelling, stomach pain, or difficulty breathing. Your provider will stop treatment with enalaprilat if angioedema happens.
Sometimes, taking enalaprilat can cause your blood pressure to drop too much. This can make you feel dizzy, tired, or lightheaded. This side effect is more common when you first start enalaprilat or when the dose is raised. Your providers will closely monitor your blood pressure and make sure you stay well-hydrated. Lie down and contact your healthcare team if you feel dizzy, lightheaded, faint, tired, or confused while you're getting treated with enalaprilat. Your providers might give you IV fluids to help bring your blood pressure back to safe levels.
Enalaprilat is usually good for the kidneys. But in some cases, it can make kidney problems worse. The risk is higher for people who have certain types of kidney problems, such as renal artery stenosis or kidney problems due to severe heart failure. Your provider might order lab tests every so often to make sure your kidneys are healthy and working properly. Your providers will check your kidneys before starting enalaprilat and periodically during treatment. Your providers will adjust your dose or make other changes to your treatment plan to prevent any damage from getting worse if they notice kidney problems on your lab test results.
Enalaprilat can raise the amount of potassium in your body, which can sometimes be dangerous. Your risk of developing high potassium is greater if you have diabetes or kidney problems or if you're taking other medications that also raise potassium levels. For this reason, make sure your provider knows your full medical history and what medications you're taking before starting treatment. Tell your healthcare provider right away if you experience signs of high potassium levels, such as nausea, muscle weakness, or abnormal heartbeat.
In some rare cases, people who took ACE inhibitors like enalaprilat developed a blockage in their bile duct. This condition can lead to liver problems or liver failure. Your provider might order blood tests to check your liver health from time to time. Let your provider know right away if you notice symptoms of liver problems, such as tiredness, stomach pain, or yellowing of your skin.
Your dose might be different if you have kidney problems or if you're at risk for severely low blood pressure (e.g., heart failure, dialysis, dehydration).
