MONDAY, Jan. 13, 2014 (HealthDay News) — Drinking tea might reduce the consequences of the medication beta-adrenergic blocking agent (Corgard), accustomed treat high pressure, a replacement tiny study suggests.
Researchers gave ten volunteers one dose of thirty milligrams of beta-adrenergic blocking agent once that they had consumed either water or regarding 3 cups of tea daily for fourteen days.
When researchers tested blood levels of the drug, they were seventy six p.c lower within the cluster that drank tea compared to the water-drinking cluster.
According to the study’s authors, which means that “patients treated with beta-adrenergic blocking agentought to avoid taking tea?” They revealed the findings on-line Gregorian calendar month. Thirteen in Clinical pharmacological medicine & medical specialty.
The researchers embrace Shingle Mistake at Fukushima Medical University in Japan and alternative universities in European country, Japan and European nation.
“Individuals UN agency take beta-adrenergic blocking agent and conjointly consume tea ought to bear in mind of this potential interaction and discuss this with their MD,” suggested Dr. Gregg Fonarow, an academician of medicine at the University of Calif., la, and a voice for the Yankee Heart Association. He reviewed the findings however failed to participate within the study.
Nadolol is not the solely drug that interacts with food or beverages. as an example, grapefruit and grapefruit juices will act with medicines, like cholesterol-lowering medicines and a few pressure medicine, per the U.S. Food and Drug Administration.
Researchers for the new study say ingredients within the tea square measure thought to interfere with the absorption of the medication within the bowel.
Nadolol could be a sort of pressure lowering drug called a blocker, accustomed treat each high pressure and angina, the hurting related to cardiopathy.
Beta blockers, in general, work by reducing the guts rate and also the heart’s employment and reducing the output of blood, therefore lowering pressure, per the Yankee Heart Association.
In the us, beta-adrenergic blocking agent is employed less oftentimes than alternative beta blockers, Fonarow aforementioned.
“It’s not a normally used blocker,” in agreement Dr. Suzanne Steinbaum, a specialist and director of women’s heart health at Lenox Hill Hospital, in the big apple town, and a voice for the Yankee Heart Association’s Go Redford ladies campaign.
Among the new study’s limitations square measure the tiny range of patients enclosed, just 10, Steinbaumaforementioned. And he or she believes that quantity of tea consumed would be uncommon, a minimum of within us. “It is rare to examine a patient UN agency drinks quite 2 cups of tea every day,” she aforementioned of her own patients.
Fonarow aforementioned that the results might apply solely to tea and beta-adrenergic blocking agent. “It isn’t clear that those receiving alternative heart medications and drinking tea got to agonize, or that these findings apply to tea,” he said.
Also, though the study showed reduced levels of beta-adrenergic blocking agent in patients UN agency drank tea; it couldn’t establish a cause-and-effect relationship. The researchers note that larger studies square measure required to know however tea might react with medicine like beta-adrenergic blocking agent.
The study was funded by part by the Japanese Ministry of Education, Culture, sport, Science &Technology.
