Carvedilol is the drug itself among the options, so the correct choice is the oral form of carvedilol. It’s a nonselective beta-blocker with alpha-1 blocking activity, used after myocardial infarction to reduce mortality in patients with left-ventricular dysfunction. The other options are different beta-blockers (metoprolol tartrate, propranolol, atenolol) and, while they can be used in various cardiac settings, they are not carvedilol.
