  • Inhibitors of the RAA System lasting effect than does captopril. Indications are hypertension and cardiac failure. Lowering of an elevated blood pressure is predominantly brought about by diminished production of angiotensin II. Impaired degradation of kinins that exert vasodilating actions may contribute to the effect. In heart failure, cardiac output rises again because ventricular afterload diminishes due to a fall in peripheral resistance.

  • Hypertension and coronary heart disease (CHD) are of great importance. Hypertension affects above 20% of the total population of the USA with its major impact on those over age 50. CHD is the cause of death in 30% of males and 22% of females in England and Wales. Management requires attention to detail, both clinical and pharmacological. The way drugs act in these diseases is outlined and the drugs are described according to class.

  • Cardiovascular disease, including coronary heart disease, strokes and diseases of other arteries, is a major cause of early death and disability. For many years the major markers of disease risk have been well recognised: these include high blood cholesterol levels and smoking. But it has also been recognised that these markers do not account for all cardiovascular risk. Furthermore, treatments that are highly effective in altering these markers, for instance the ‘statin’ drugs used to lower cholesterol, do not remove risk entirely: typically they reduce it by about 30% or less.

  • Vasodilators alogues such as iloprost, or prostaglandin E1 analogues such as alprostanil, mimic the actions of relaxant mediators. Ca2+ antagonists reduce depolarizing inward Ca2+ currents, while K+-channel activators promote outward (hyperpolarizing) K+ currents. Organic nitrovasodilators give rise to NO, an endogenous activator of guanylate cyclase. Individual vasodilators. Nitrates (p. 120) Ca2+-antagonists (p. 122). "1antagonists (p. 90), ACE-inhibitors, AT1antagonists (p. 124); and sodium nitroprusside (p. 120) are discussed elsewhere.

  • Decreased aldosterone synthesis may be due to primary adrenal insufficiency (Addison's disease) or congenital adrenal enzyme deficiency (Chap. 336). Heparin (including low-molecular-weight heparin) inhibits production of aldosterone by the cells of the zona glomerulosa and can lead to severe hyperkalemia in a subset of patients with underlying renal disease, diabetes mellitus, or those receiving K+-sparing diuretics, ACE inhibitors, or NSAIDs.

  • The purpose of this dictionary is to provide a convenient and affordable personal desk reference resource. The authors, who have many years experience in pharmacological research, teaching and editing, recognized a need for a single up-to-date volume encompassing material that hitherto could be gathered only from a well-stocked library. This book comprises two main sections: an A-Z listing of drugs and their properties; and a descriptive glossary of technical terms.

  • Somatic angiotensin-converting enzyme (ACE) contains two homologous domains, each bearing a functional active site. Studies on the selectivity of these ACE domains towards either substrates or inhibitors have mostly relied on the use of mutants or isolated domains of ACE.

  • The increasing awareness of the importance of chirality in the context of biological activity has stimulated a growing demand for efficient methods for industrial synthesis of pure enantiomers including chiral antiinflammatory drugs such as naproxen (Xin et al., 2001) and ibuprofen (Lee et al., 1995; Ducret et al., 1998; Xie et al., 1998; Arroyo et al., 1999; Chen and Tsai, 2000); antihypertensive agents such as angiotensin-converting enzyme (ACE) inhibitors (e.g., captopril, enalapril, ceranopril, zofenapril, and lisinopril); and the calcium channel- blocking drugs such as diltiazem.

  • In stark contrast to the extraordinary lengths to which patients in wealthy countries will go to treat ischemic cardiomyopathy, young patients with nonischemic cardiomyopathies in resource-poor settings have received little attention. These conditions account for as many as 25–30% of admissions for heart failure in sub-Saharan Africa and include poorly understood entities such as peripartum cardiomyopathy (which has an incidence in rural Haiti of 1 per 300 live births) and HIV cardiomyopathy.

  • Angiotensin-converting–enzyme (ACE) inhibitors are effective in reducing the risk of heart failure, myocardial infarction, and death from cardiovascular causes in patients with left ventricular systolic dysfunction or heart failure. ACE inhibitors have also been shown to reduce atherosclerotic complications in patients who have vascular disease without heart failure.

  • A protocol to follow the processing of angiotensin I into angiotensin II by rabbit angiotensin-converting enzyme (ACE) and its inhibition by a novel natural antagonist, the leech osmoregulator factor (LORF) using capillary zonal electrophoresis is described. The experiment was carried out using the Beckman PACE system and steps were taken to determine (a) the migration profiles of angiotensin and its yielded peptides, (b) the minimal amount of angiotensin II detected, (c) the use of different electrolytes and (d) the concentration of inhibitor. ...

  • Angiotensin-converting enzyme-2 (ACE2) may play an important role in cardiorenal disease and it has also been implicated as a cellular receptor for the severe acute respiratory syndrome (SARS) virus. The ACE2 active-site model and its crystal structure, which was solved recently, highlighted key differences between ACE2 and its counterpart angiotensin-converting enzyme (ACE), which are responsible for their differing substrate and inhibitor sensitivities.
