Potential Negative Interaction
In one study, ingestion of 250 ml (approximately 1 cup) of grapefruit juice one hour before and together with sildenafil increased the total amount of sildenafil absorbed by 23%, but tended to delay the absorption of the drug.1 The authors of this study recommended that sildenafil and grapefruit juice not be taken together.
Pomegranate juice has been shown to inhibit the same enzyme that is inhibited by grapefruit juice.2 , 3 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 sildenafil in the same way that grapefruit juice does.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
