Figure 1: The chemical structure of dichloroisoprenaline or dichloroisoproterenol (), abbreviated DCI — the first β-blocker to be developed. β adrenergic receptor antagonists (also called beta-blockers or β-blockers) were initially developed in the 1960s, for the treatment of angina pectoris but are now also used for hypertension, congestive heart failure and certain arrhythmias.

Beta blockers vary in their lipophilicity (fat solubility) and in turn in their ability to cross the blood–brain barrier and exert effects in the central nervous system. [76] Beta blockers with greater blood–brain barrier permeability can have both neuropsychiatric therapeutic benefits and side effects, as well as adverse cognitive effects ...
Sir James Whyte Black (14 June 1924 – 22 March 2010 [2]) was a Scottish physician and pharmacologist.Together with Gertrude B. Elion and George H. Hitchings, he shared the Nobel Prize for Medicine in 1988 for pioneering strategies for rational drug-design, which, in his case, led to the development of propranolol and cimetidine.
The first life insurance policies were taken out in the early 18th century. The first company to offer life insurance was the Amicable Society for a Perpetual Assurance Office, founded in London in 1706 by William Talbot and Sir Thomas Allen.
Beta-blockers with intrinsic sympathomimetic activity: acebutolol, pindolol; Some common side effects include increased airway resistance for non-selective beta-blockers, exacerbation of peripheral vascular diseases, and hypotension [15] Beta-blockers are contraindicated in patients with second- or third-degree atrioventricular block.
The Blue Light Blocker Sephora We loved seeing vitamin C in this mist for acne-prone skin, but we were especially thrilled when we saw the cocoa seed oil, included to help protect against blue light!
Metoprolol is classified as a moderately lipophilic beta blocker. [37] More lipophilic beta blockers tend to cross the blood–brain barrier more readily, with greater potential for effects in the central nervous system as well as associated neuropsychiatric side effects. [37] Metoprolol binds mainly to human serum albumin with an unbound ...
Jack Blocker may have been put through by the crew on 'American Idol' but he has proved he definitely belongs in the Top 8
