Pharmacotherapy of human hypertension is effective, safe and well-tolerated. Antihypertensive drugs are of three broad classes: diuretics, sympatholytics and vasodilators. The use of each class is discussed and a summary of therapeutic considerations offered for representative agents. Recent trends in antihypertensive therapy are identified.
Although the outlook for a pronounced improvement in the ischaemic limb that cannot be surgically treated remains bleak, cessation of smoking, encouragement of exercise, and the withdrawal of vasoconstricting agents may give some symptomatic relief. There is little evidence that vasodilators or antiplatelet agents have much to offer.
Two prostacyclins (prostaglandin E(1) and prostaglandin I(2)) are potent vasodilators. Aerosolized prostacyclins reduce pulmonary artery pressure, improve right heart function, and increase arterial oxygenation by improving ventilation/perfusion matching. This report describes aerosolized prostacyclins and compares them to inhaled nitric oxide. I review the types of inhalable prostacyclins and ...
this hypothesis would need to be tested in a prospective trial. How long had nifedipine been discontinued in the authors' patient prior to repeat cardiac catheterization? How long has the patient's exercise tolerance remained dramatically improved since the discontinuation of vasodilators?
Raynaud's phenomenon (RP) is rare in young children. We describe two infants with severe RP, manifesting as fingertip necrosis, who were resistant to conventional vasodilators and were treated successfully with iloprost, a prostacyclin analogue. The application of iloprost is safe and should be considered in children with threatening ischemic digits.
Pulmonary hypertension significantly changes biventricular anatomy and physiology, frequently evolving to clinical deterioration and right ventricular failure. The case of a woman developing atrial arrhythmias complicating dipyridamole stress in concomitance with scintigraphic "D-shaped" left ventricle is briefly reported. Although rare, our finding may suggest that nonselective vasodilators sh...
Ergot-induced disease in humans was known long before Biblical times and has been the root cause for countless human epidemics spanning from the early fourteenth century to the late sixteenth century. In contrast, many of these same ergot alkaloids have been utilized for their medicinal properties to mitigate migraine headaches and have had indications as anti-carcinogens. Although ergot alkalo...
The objective of this study was to evaluate the performance of growing cattle when intensively grazing stockpiled endophyte-infected (E+), endophyte-free (E-), and nontoxic endophyte-infected (EN) tall fescue during the winter. The experiment was conducted over 5 consecutive winters. In each year, plots (1 ha each, 4 per treatment) were harvested for hay in August, fertilized in September, and ...
The routine use of vasodilators in patients with acute coronary syndromes or other groups undergoing percutaneous coronary intervention (PCI) cannot be recommended at present. However, in the event of no-reflow occurring following PCI, intracoronary adenosine or verapamil should be administered.
Ceylon Medical Journal The wasp (Vespa affinis) is common and widely distributed in Sri Lanka. Wasp venom is known to contain factors that release histamine, enzymes, haemolysins, neurotoxins and vasodilators [1]. Case reports with severe multi-organ dysfunction after wasp stings are few in literature. We report two patients who developed severe multi-organ dysfunction following multiple wasp b...
