Potential Negative Interaction
Amlodipine has been shown to raise blood levels of DHEA-sulfate in insulin-resistant, obese men with high blood pressure.1
Ingestion of grapefruit juice has been shown to increase the absorption of felodipine (a drug similar in structure and action to that of amlodipine) and to increase the adverse effects of the medication in patients with hypertension. Until more is known, it seems that grapefruit juice should not be ingested by people taking amlodipine or similar drugs.2 The same effects might be seen from eating grapefruit as from drinking its juice.
As pleurisy root and other plants in the Aesclepius genus contain cardiac glycosides, it is best to avoid use of pleurisy root with heart medications such as calcium channel blockers.3The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Pomegranate juice has been shown to inhibit the same enzyme that is inhibited by grapefruit juice.4 , 5 The degree of inhibition is about the same for each of these juices. Therefore, it would be reasonable to expect that pomegranate juice might interact with amlodipine in the same way that grapefruit juice does.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
