The Mayo Clinic indicates that beta blockers are medications useful in treating high blood pressure. They act on the naturally produced chemical adrenaline by blocking its effects, thus decreasing heart rate and lowering blood pressure. Beta blockers are helpful in improving blood flow to the body by opening the blood vessels. Beta blockers may also be used for people in mild to moderate heart failure in conjunction with other medications.

Metoprolol is a beta blocker marketed by the brand name of Lopressor or Toprol XL. The National Library of Medicine indicates that this medication is used primarily to treat high blood pressure. Metoprolol is also used for preventing chest pains and in combination with other medications to treat heart failure. Side effects may include stomach pain, nausea and depression. This medication is not prescribed without physician recommendation.
Atenolol
Atenolol is marketed under the brand Tenormin for blood pressure treatment. Tenormin has an off-label use as well in treating alcohol withdrawal, migraine headaches and anxiety. Tenormin is recommended to be taken regularly for maximum results in treating high blood pressure.
