Abstract

Beta-blockers are valuable agents in the treatment of hypertension, being useful at all stages of hypertension except when heart failure is present. They are usually the first choice of therapy in younger patients with mild to moderate hypertension. In elderly or Black patients, added diuretic therapy is essential. Otherwise diuretic therapy is only added if beta-blockade alone is unsuccessful, as it will be in 30-50% of patients. Requirements for an ideal beta-blocker are stated. Costs of currently available beta-blockers are given. The prices of some compare well with those of vasodilators, but thiazide diuretics are much cheaper. Centrally acting agents tend to fall into an intermediate price range. Beta-blockers cannot be prescribed without prior enquiry into a history of asthma (an absolute contraindication) or bronchospasm (an indication for a cardioselective agent), nor without examination of the heart and lungs of the patient.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
