Pentaerythritol tetranitrate (PETN) is an organic nitrate that, like nitroglycerin
(NTG), undergoes biotransformation to release its active metabolite nitric oxide or
a nitric oxide adduct. Importantly, compared with other nitrates, PETN has been shown
to have antioxidant properties and to inhibit the progression of atherosclerosis.

Furthermore, animal studies and a recent report from our laboratory suggest that
tolerance development does not occur during continuous therapy with PETN.

These effects are consistent with the finding that PETN therapy is not associated
with increased plasma concentrations of markers of oxidative stress.

In the present report, we investigated the effects of continuous therapy with transdermal
NTG compared with oral PETN on endothelium-mediated vasodilation.To read this article in full you will need to make a payment
