7 Examples Of Beta Blockers
Beta blockers were thought to be less effective for the elderly, but this is no longer considered the case. The characteristics of the various beta blockers, which can be spotted since their scientific names end in “lol” can be found in the examples below:
1. Acebutolol (Sectral, Acebutolol Capsules, Acebutolol Hydrochloride Capsules) comes in 200 or 400 mg capsules. It’s usually prescribed for once daily starting at 200 mg up to a maximum of 1200 mg. The liver eliminates acebutolol more than the kidney.
2. Atenolol (Tenormin, Atenolol Tablets) is available in 25, 50, or 100 mg tablets. The starting dose is usually 25 mg once a day up to a maximum of 200 mg once a day.
3. Atenolol also comes in combination form as Tenoretic 50, which is 50 mg of atenolol and 25 mg of the diuretic, chlorthalidone; and Tenoretic 100, which is 100 mg of atenolol and 25 mg of chlorthalidone. Atenolol and Chlorthalidone Tablets are the same two combinations by another drug company. Atenolol in any form is eliminated by the kidney.
4. Bisoprolol (Zebeta) is supplied as 5 and 10 mg tablets. For high blood pressure, the starting dose is usually 5 mg, and some may do well with half that dose. The maximum dose is 20 mg. The characteristics of bisoprolol are similar to all other members of this group. Bisoprolol is eliminated by both the kidneys and the liver so disease of either organ will increase blood levels of the drug.
5. Carteolol (Cartrol Filmtab Tablets) is sold as a 2.5 or a 5 mg tablet. 2.5 mg is usually taken once a day up to a maximum of 10 mg once daily. This drug is eliminated more by the kidney than the liver.
6. Carvedilol (Coreg) comes as 3.125, 6.25, 12.5, and 25 mg tablets. The starting dose is usually 6.25 mg twice daily up to a maximum of 50 mg divided into two doses. The liver breaks down carvedilol. People with liver disease may accumulate this drug in their bloodstream.
7. Labetalol (Normodyne, Trandate, Labetalol HC1 Tablets) comes as 100, 200, and 300 mg tablets. It differs from most of the other beta blockers because of its effect on other receptors called alpha receptors. This often causes dizziness, and the drug has been associated with fever and liver abnormalities. The dose is usually 100 mg twice daily up to 1200 mg divided into two doses. The liver is the major organ of elimination.
