Medical News: Grapefruits Causing Adverse Reactions to Prescription Drugs

Are you eating grapefruits while taking prescription drugs? If you are, viagra buy malady you might want to re-think it.

The New York Times reported that grapefruit can cause adverse reactions to a wide variety of prescription drugs, viagra usa leading to accidental overdose, high blood pressure, and even death. Drugs causing these adverse reactions include common cholesterol-lowering drugs, anticancer drugs, immunosuppressant medications, AIDS medications, birth control pills, and more.

The reason is quite straight forward. According to the Times, grapefruit contains a chemical that inhibits an enzyme in the gut that deactivates drugs to a safe dosage for the body to absorb. Since the drug is no longer deactivated, the body absorbs much more of it than normal.

“Under normal circumstances, the drugs are metabolized in the gastrointestinal tract, and relatively little is absorbed, because an enzyme in the gut called CYP3A4 deactivates them,” reported the Times. “But grapefruit contains natural chemicals called furanocoumarins, that inhibit the enzyme, and without it the gut absorbs much more of a drug and blood levels rise dramatically.”
