However , lack of data specifically examining outcomes in PAD patients should not detract from the overwhelming evidence on the benefit of treating hypertension and lowering blood pressure
BACKGROUND Peripheral arterial disease ( PAD ) causes considerable morbidity and mortality .
Hypertension is a risk factor for PAD .
Treatment for hypertension must be compatible with the symptoms of PAD .
Controversy regarding the effects of beta-adrenoreceptor blockade for hypertension in patients with PAD has led many physicians to stop prescribing beta-adrenoreceptor blockers .
Little is known about the effects of other classes of anti-hypertensive drugs in the presence of PAD .
This is the second up date of a Cochrane review first published in 2003 .
OBJECTIVES To determine the effects of anti-hypertensive drugs in patients with both raised blood pressure and symptomatic PAD in terms of the rate of cardiovascular events and death , symptoms of claudication and critical leg ischaemia , and progression of atherosclerotic PAD as measured by ankle brachial index ( ABI ) changes and the need for revascularisation ( reconstructive surgery or angioplasty ) or amputation .
A dose-effect study of beraprost sodium in intermittent claudication.
We compared the efficacy and safety of three doses of beraprost sodium , an epoprostenol analogue , with placebo in the treatment of intermittent claudication ( Fontaine 's stage II ) . One hundred sixty-four patients were r and omized to receive either placebo , 20 micrograms beraprost sodium ( BPS60 group ) , 40 micrograms beraprost sodium ( BPS120 group ) , or 60 micrograms beraprost sodium ( BPS180 group ) three times daily administered orally in a double-blind manner for 12 weeks . Treadmill exercise tests were performed twice during an initial selection phase ( D-28 and D0 ) at week 10 ( at trough beraprost concentration ) and week 12 ( at peak beraprost concentration ) of the treatment phase . At week 10 , all groups showed an increase in pain-free walking distance , and this distance was greatest in the BPS60 and BPS120 groups ( p = 0.055 ) . At week 12 , a similar pattern was observed , and the difference was significant between the groups ( p = 0.023 ) . The most frequent adverse events reported were gastrointestinal disorders , headaches , skin disorders , and flushes . Patients who received either 60 or 120 micrograms of beraprost sodium daily had an increased pain-free walking distance . Further studies are required to investigate why the highest dose used ( 180 micrograms daily ) showed lower efficacy . Having both vasodilating and antiplatelet properties and being able to increase pain-free walking distance in the short term , beraprost sodium is a promising drug for the treatment of intermittent claudication
