Green Tea May Hinder a Blood Pressure Medication

Green Tea Washes Out Nadolol

Investigators gave one dose of 30 mgs of nadolol after that they had have either water or around three glasses of green tea daily for 2 weeks to 10 volunteers.

When investigators examined blood amounts of the drug, these were 76% lower in the team that drank green tea in comparison with the water-ingesting group.

In accordance with the study's writers, that signifies that individuals treated with nadolol should prevent taking green tea extract. They released the findings in Medical Therapeutics & Pharmacology Journal.

The investigators contain Shingen Misaka at other colleges in Italy, Japan and Germany and Medical University of Fukushima in Japan.

"People who take nadolol as well as have green tea should know about this possible interaction and have it discussed with their doctor," suggested Gregg Fonarow, a cardiology professor at the College of California. He commented the findings but didn't take part in the research.

Other Products Can Affect Medications As Well

Nadolol is not the only drug that socializes with food or drinks. For example, grapefruit can communicate with medications, including cholesterol-lowering medications and a few blood pressure drugs, in accordance with the U.S. FDA.

Research workers for the new research say fixings in the green tea extract are believed to restrict the absorption of the medicine in the gut.

Nadolol is a variety of blood-pressure lowering drug called a beta-blocker, used to handle both hypertension and angina, the chest discomfort related to heart condition.

Beta blockers, generally, function by decreasing the production of blood and decreasing the heart's workload and one's heart rate, thereby lowering pressure, in accordance with the AHA.

In the USA, nadolol is employed less often than other beta-blockers.

"it is not a frequently used beta-blocker," concurred Dr. Suzanne Steinbaum, a cardiac surgeon at Lenox Hill Hospital.

More Proof Is Needed

One of the new study's limits are the few of patients contained, only 10, Steinbaum stated. And she considers that quantity of tea have would be uncommon, at least in the USA. "It's uncommon to see someone who drinks a lot more than two glasses of green tea a day," she stated of her own individuals.

The results may employ solely to nadolol and green tea. It isn't clear that these receiving other heart medicines and consuming green tea demand to be involved, or these findings affect black tea.

Additionally, even though the research revealed reduced amounts of nadolol among patients who consumed green tea, it cannot confirm a cause-and-effect relationship. The investigators note that bigger studies are needed to comprehend how green tea can respond with medications.

The research was financed by Japan Ministry of Education, Culture, Sports, Science and Tech.
