Summary the aim of the study was to compare the pulmonary effects of four beta-blockers with different ancillary properties: propranolol (non-beta 1 selective without isa), oxprenolol (non-beta 1 selective with isa), atenolol (beta 1 selective), and celipropol (beta 1 selective with mild beta 2-agonist and alpha 2-antagonist activity) in hypertensive patients with chronic obstructive lung . At present, retrospective analysis is the only tool available to address the issue of whether the β-blocker propranolol should now be deemed inferior to the β 1-selective β-blockers metoprolol and atenolol. Beta blockers following ml, gottlieb et al18 found that the mortality was identical with metoprolol and atenolol, while it was higher with propranolol (non-cardioselective). The beta blockers compared include carvedilol vs metoprolol, pindolol vs propranolol, betaxolol vs propranolol, and betaxolol vs metoprolol tartrate some beta blockers, such as acebutolol and pindolol , also have beta agonist properties, known as intrinsic sympathomimetic activity (isa).

2) p-substitution (to the phenoxy): increased beta1 selectivity (eg: metoprolol, atenolol, acebutolol) 3) pindolol, carteolol are partial agonists (since they have significant beta agonistic activity along with their blocker properties).
