Look at the wording. "Beta blockers" are blocking "beta". So what is the "beta" they are blocking? If its not "beta cells", what other "beta" is there?
Beta is a letter of the Greek alphabet and as such is used for many things.
Adrenergic receptors throughout the human body are broken up into Alpha and Beta (just think of them as being named A and B) with each receptor being broken up into several subtypes of each. "Beta blocking" medicines have many effects depending on which type of receptor is being targeted by the medicine, Beta 1, 2 or 3.
It's best thinking of them as a class of medicines which have a range of effects within the body. They are in no way related to the Beta cells that are within the pancreas.
