| Research Abstract |
Grapefruit juice(GFJ) was reported to increase the concentration of calcium channel(Ca) blockers by inhibiting cytochrome P450(CYP) 3A4.The aim of this study was to clarify effect of the intake of GFJ on blood pressures in hypertensive patients treated with Ca blockers, amlodipine and nifedipine. Five Japanese patients consumed GFJ and water in 2-way crossover trial. Home blood pressures were measured by electrical devices. There was no significant difference of blood pressure of patients between GFJ phase and water phase(126/82 mmHg in GFJ phase vs 126/80 mmHg in water phase). In conclusion, there might be little impact of the intake of GFJ on blood pressure in hypertensive patients.
