Which Beta-1 Selective Beta-Blocker is administered through injection?

  1. Atenolol

  2. Esmolol

  3. Metoprolol tartrate

  4. Metoprolol succinate

The correct answer is: Esmolol

Esmolol is the only Beta-1 selective beta-blocker that is administered through injection. Atenolol, Metoprolol tartrate, and Metoprolol succinate are all administered orally. Although they are all Beta-1 selective beta-blockers, they are not administered through injection. This is an important distinction to note as different forms of administration can affect the onset and duration of the drug's effects. Therefore, B is the correct answer to this question.
