Key takeaways
Metoprolol tartrate (Lopressor) and Tenoretic (atenolol/chlorthalidone) are both used to manage high blood pressure, but they have some key differences. Metoprolol tartrate is a selective beta blocker that slows down your heart rate and is also used to treat chest pain and lower the risk of death after a heart attack. It is typically taken twice daily with food. On the other hand, Tenoretic combines a beta blocker (atenolol) with a diuretic (chlorthalidone) to lower blood pressure by slowing the heart rate and removing extra water and salts from the body. Tenoretic is usually taken once daily and can be taken with or without food. Both medications are available as a generic forms, making them more affordable. Tenoretic is not typically used for initial treatment due to its fixed-dose combination, making dose adjustments difficult. Additionally, Tenoretic is not safe for use during pregnancy or breastfeeding, whereas metoprolol tartrate may be an option for breastfeeding mothers. Both medications can cause dizziness and tiredness, but Tenoretic may also increase urination due to its diuretic component.
