0 The content of caffeine in drugs increase the risk of stroke

The content of caffeine in drugs increase the risk of stroke - Quite often we find that the caffeine in the composition of common drugs are sold freely on the market or pharmacy. From now on, you should be wary if the caffeine found in drugs consumed. Because a study in Korea found evidence that the caffeine content in the medicine can increase the risk of stroke by two or three times.

The results of this study contradict previous research which states that coffee and tea can strengthen protective effect on the heart. However, the authors also explain that the two studies appear contradictory this may have common ground. People who consume less coffee or tea are known to be affected by drugs that contain caffeine.

Whats more, researchers found that caffeine could be contained in a variety of drugs, ranging from ordinary painkillers, or cold medicines are sold in general and widely consumed by the public, as reported by the NY Daily News.

"Caffeine has properties that cause the blood vessels to tighten and increase the pressure on the blood flow," said lead researcher Nam-Kyong Choi from Seoul national University College of Medicine.

These results were found after researchers observed 940 adult patients who had a stroke. They compared the drugs consumed, and found that people in medicine containing caffeine are more likely two to three times the stroke.

However, when compared with the coffee drinking habits, researchers found that participants who had a habit of drinking coffee every day and taking medications that contain caffeine does not seem to have a pretty big risk.

The discovery was actually quite strange because coffee and tea contain more caffeine than are contained in medicines. Even so Choi assume that coffee or tea may contain substances that are useful and reduce the effects of caffeine in it. Although the finding that caffeine can increase the risk of stroke, but Choi still do not know the mechanism.
