About Beta Blockers
Beta blockers are agents that block the effect of neurotransmitters responsible for the body's ‘fight or flight’ response. This results in dilation of blood vessels, and eventually to reduced heart rate and lowered blood pressure.
Beta blockers are a common treatment for hypertension and for co-existing cardiovascular problems. Examples of beta blockers include: atenolol, carvedilol, labetalol, metoprolol, nadolol, propranolol, and timolol.
When taking this medication, keep in mind the following:
- Continue taking the medication even if you feel well. Abrupt discontinuation may result in rebound hypertension.
- You should take it at the same time each day.
- The drug is not recommended if you are also an asthmatic as this blocks your airways and hinders proper breathing.
- In some patients, beta blockers may cause diarrhea.
