Cochrane corner: beta-blockers for hypertension

BaCkground Beta-blockers refer to an assorted group of medications that block the action of endogenous catecholamines on beta-adrenergic receptors. The β1 and β2 receptors are the primary beta-adrenergic receptors in the human cardiovascular system. Betablockers differ in their β1/β2-receptor selectivity and vasodilatory properties. Based on this diversity, beta-blockers have been categorised i...

Paraoxonase Inhibition by Propranolol

There are many evidences that human serum paraoxonase activity modifies plasma lipid profile and paraoxonase has an antiatherogenic property. Non-selective beta-blockers affect plasma lipid profile too, but they have atherogenic property when patients take these drugs in long term. In this study the effect of propranolol, a non-selective beta-blocker, on paraoxonase activity was investigated. L...

A Clinico-Epidemiological Study on Poisonings due to Cardiovascular Drugs in Ahvaz, Iran

Background: Overdoses with cardiovascular drugs are related with significant morbidity and mortality. Beta-adrenergic blockers, calcium-channel blockers (CCBs), thiazide, digoxin and angiotensin converting enzyme (ACE) inhibitors represent five of the most important classes of cardiovascular drugs. Overdoses with cardiovascular drugs are typically caused by exploratory ingestion by children or ...
