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.

To improve the ability of their compounds to cross the blood brain barrier, they changed the ethanolamine side chain of beta blockers to a morpholine ring, leading to the synthesis of viloxazine. [13]: 610 [30]: 9 It was first described in the scientific literature as early as 1972. [10] The medication was first marketed in 1974.
This long duration of action made the treatment for severe asthma and COPD more convenient for the patients because it is inhaled twice a day. [1] In 2013 an extra long-acting β 2-agonist, vilanterol, was marketed. Its duration of action lasts for 24 hours which should improve patients' compliance and make the treatment more convenient. [2]
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.
Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure. [7] [8] It is taken by mouth. [7]
