In brief: Quite the opposite!

Grapefruit juice(GFJ) affects the intestine to cause certain medications to be absorbed into the blood stream in HIGHER than normal amounts.
This can lead to EXCESSIVE blood levels of certain medications including Calcium Channel Blocker medications for hypertension. **The effect of grapefruit juice can last longer than 24 hours. AVOID GFJ if you take these medicines:> http://bit.ly/1NQ7OuZ

In brief: Not expected

In fact, grapefruit juice tends to interfere with the breakdown of some medications leading to overdosing.
