Betal blockers and Cardiotonic agent ,,, are they all the same ??
I have used four types of antiangina medicians some fall under the beta blockers: bisoprolol (concor), atenolol (tenormin), metoprolol (lopressor) however the last medician was cardiotonic agent ivbradine.
Are these medicians all the same ?? I have heard the name beta-blocker for quite some time but never heard of a cardiotonic agent.
