Key takeaways
Propranolol (Inderal LA, Inderal XL, Innopran XL) and lisinopril (Zestril, Qbrelis) are both medications used to treat high blood pressure, but they belong to different classes and work in different ways. Propranolol is a non-selective beta blocker that slows down your heart rate and relaxes blood vessels, while lisinopril is an angiotensin-converting enzyme (ACE) inhibitor that relaxes blood vessels by blocking a specific protein. Propranolol can also be used for conditions like tremors, migraines, and performance anxiety, whereas lisinopril is also used to treat heart failure and reduce the risk of death after a heart attack. You typically take propranolol multiple times a day if it's the immediate-release form, but only once daily if it's the extended-release form. Lisinopril is usually taken once daily. Common side effects of propranolol include dizziness and tiredness, while lisinopril can cause a dry cough and dizziness. Both medications are available in generic forms, making them more affordable.
Lisinopril (Zestril) is an angiotensin-converting enzyme (ACE) inhibitor that's a first-choice medication used for lowering blood pressure. It's also approved to treat symptoms of heart failure and also to lower the risk of death after a heart attack. Lisinopril (Zestril) is a tablet that's taken by mouth, typically once daily. It's also available as an oral solution. Some common side effects of this medication include cough, dizziness, and headache.
