Interaction Details
Lisinopril is classified as belonging to the following category: Lisinopril
Theoretically, green tea might reduce the levels and clinical effects of lisinopril.
Preliminary clinical research shows that a single dose of green tea extract reduces plasma concentrations of lisinopril. Compared to a control group, peak levels and area under the curve (AUC) of lisinopril were reduced by approximately 71% and 66%, respectively. This may be due to inhibition of organic anion transporting polypeptides (OATP) by green tea catechins The interaction is thought to be due primarily to the epigallocatechin gallate (EGCG) content of green tea.

Green Tea Overview
Green tea is a type of tea that is made from the leaves of the Camellia sinensis plant. It is native to Asia and is widely consumed throughout the world. Green tea has a mild, slightly grassy flavor and is typically lighter in color and less astringent than black tea.
Green tea is a rich source of antioxidants, particularly a group of compounds called catechins. These antioxidants are thought to help protect cells from damage caused by free radicals. Green tea is also a good source of other nutrients, including vitamin C and several B vitamins.
Green tea is often consumed for a number of purported health benefits including reducing the risk of heart disease, immune-stimulating effects, and weight loss.
Oral green tea supplements, containing dried powder, are most often utilized for the caffeine content and used as an appetite suppressant for weight loss.
Lisinopril Overview
-
Lisinopril is used alone or in combination with other medications to treat high blood pressure in adults and children 6 years of age and older. It is used in combination with other medications to treat heart failure. Lisinopril is also used to improve survival after a heart attack. Lisinopril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors. It works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly and the heart can pump blood more efficiently.
-
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
