Green Tea Reduces Blood Pressure Drug Nadolol’s Effectiveness

A research has been carried out by Fukushima Medical University, as per which it has been unveiled that green tea can reduce the effectiveness of blood-pressure drug nadolol.

In order to reach at the above result, an experiment was carried out in which 10 healthy men and women took part. Participants were asked to have two cups of green tea a day for two weeks and also after having water.

After having the tea or water, the researchers asked them to take 30 mg dose of nadolol. When results were assessed, it was found that green tea has diluted the effect of the blood pressure drug. Green tea brought a decline by cutting the concentration that entered blood stream.

The researchers are of the belief that chemicals in green tea might interfere in the absorption ability of intestine with regard to the drug. This has led the researchers to affirm that patients taking the drug should try not to take green tea.

"Individuals who take nadolol and also consume green tea should be aware of this potential interaction and discuss this with their physician", affirmed Dr. Gregg Fonarow, a spokesman for the American Heart Association. The research has been published in the journal Clinical Pharmacology & Therapeutics.
