As the name implies, beta blockers work by blocking beta receptors in the body.Beta receptors are located in a number of places within the body, including the heart and blood vessels.tenolol helps to block a specific type of beta receptor called beta-1 receptors. By blocking beta-1 receptors, the medication causes the reverse effect of adrenaline. It decreases heart rate, systolic and diastolic blood pressure, and the workload of the heart.
