ABSTRACT

Useful drug therapy for inhibiting the extension of an aortic aneurysm or promoting its involution has not yet been established. Hypertension is a known risk factor for extension of an aortic aneurysm. However, on a cellular level it is believed that activation of nuclear factor (NF)-kappaB and matrix metalloproteinase (MMP) is involved in the extension of an aortic aneurysm. Nifedipine has been evaluated in a rat model of aortic aneurysm and it was found to inhibit activation of MMP and extension of the aortic aneurysm. Nifedipine also inhibited activation of NF-kappaB and these effects were independent of the antihypertensive effect of the drug. With antihypertensive and vasculoprotective effects and inhibitory actions on activation of NF-kappaB and MMP, nifedipine has potential to be a useful option in the drug treatment of patients with aortic aneurysm.
