•    Selective beta blockers. You can find this in metoprolol (lopressor, toprol xl) which mainly obstruct B1 receptors, thus resulting to the disturbance of the heart. However, it has no capacity to distress the air passageways.

Other forms of beta blockers

A perfect example for these beta blockers are pindolol (visken), labetalol (normodyne, trandate) and cardidilol (coreg). Pindolol (visken) contains intrinsic sympathomimetic activity (ISA), which denotes that it is capable of imitating the results of epinephrine and norepinephrine. It can trigger intensity in blood pressure and heart beat. Beta blockers that contain ISA have reduced effects on heart beat than drug properties that do not contain ISA.
