Interactions of ?-arginine, isosorbide mononitrate, and angiotensin II inhibitors on arterial pulse wave

Interactions of L-arginine, isosorbide mononitrate, and angiotensin II inhibitors on arterial pulse wave.

BACKGROUND Deficiency of nitric oxide (NO) production has been implicated in the pathogenesis of increased pulse wave reflection associated with systolic hypertension. We investigated the effects on systolic blood pressure (BP) and pulse wave contour of two nitrate donors, isosorbide mononitrate (ISMN) and L-arginine. METHODS The subjects were 14 elderly patients chronically treated with anti...

Effects of isosorbide mononitrate and AII inhibition on pulse wave reflection in hypertension.

The aortic pulse wave contour in isolated systolic hypertension often shows a prominent reflection peak, which combines with the incident wave arising from cardiac ejection so as to widen pulse pressure. We investigated the effects of an extended-release nitrate preparation and of 2 angiotensin II (AII) inhibitors (an AII receptor antagonist and an ACE inhibitor) on the aortic pulse wave contou...

Simultaneous measurement of plasma isosorbide dinitrate, isosorbide-2-mononitrate, and isosorbide-5-mononitrate by gas-liquid chromatography.

Isosorbide Mononitrate versus Misoprostol for Cervical Ripening

Objective: To compare the efficacy and safety of isosorbide mononitrate (IMN) versus misoprostol used to induce labour for overdue pregnancy. Setting: A prospective randomized clinical study conducted at AL-Elwiya Maternity Teaching Hospital in Baghdad from Jan. 2008 to Dec. 2008. Method: One hundred and fifty women with over due pregnancy (past date and posterm pregnancy) referred for inductio...

Effect and mechanism of action of isosorbide-5-mononitrate.

Nitrates have been shown to decrease portal pressure in cirrhotic patients with portal hypertension and this has been attributed to decreased portal venous resistance. We studied the effect and mechanism of action of oral administration of isosorbide-5-mononitrate (Is-5-Mn) (20 mg), which, unlike the dinitrate, does not require hepatic biotransformation to a vasoactive metabolite on portal and ...
