Usually none: But, Persantine is a vasodilator and can rarely cause a drop in blood pressure. It can also cause constriction of the airways of the lung, and rarely can cause a brief pause in the heart rhythm for several seconds.

A 37-year-old member asked:

Can you describe what dipyridamole is?

2 doctor answers4 doctors weighed in
Dr. Michael Fenster
Cardiology 31 years experience
Yes: Dipyridamole (dp-brand name persantine) is a platelet inhibitor and has been studied in conjunction with warfarin or coumadin. Dp acts to block the uptake of adenosine. In higher intravenous doses it causes vasodilation-specifically coronary vasodilation- and is therefore commonly used to perform pharmacological nuclear myocardial perfusion studies, commonly known as a nuclear stress test.

Aminophylline: Aminophylline reverses the vasodilatory effects of dipyridamole. However, vasopressors may still be required. Dialysis won't work since it's protein-bound.

Blood thinner: Dipyridamole is another name for persantine. This is a medication that has blood-thinning properties by preventing platelets from clumping together, and hence is often given to people who have suffered certain types of strokes. However, it also has effects on the cells that make up the walls of coronary arteries, causing them to dilate, and hence can be used in pharmacologic stress testing.

Why is dipyridamole on beer labels?

What are u drinking?: Well i never saw this on a beer label. Caution is advised in taking that drug with alcohol because of bleeding issues but i never saw it on a label. Certainly, the drug is not an ingredient of any beer so it could be a warning but i never saw it. What brand of beer did you see that on and how much did you drink? http://www.funnyforwards.com/beerwarninglabels.htm.
