Metoprolol Tartrate To Lowering High Blood Pressure
Metoprolol Tartrate is a beta-blocker medication with many uses. Beta-blockers are prescribed in conditions where the heart rate needs to be slowed. It relaxes the blood vessels and slows down the heart rate to help improve the circulation of blood around the body and to lower the blood pressure.
It’s FDA-approved for medical use since 1978 and is on the World Health Organization’s list of essential medicines. It’s even listed as one of the most effective and safest medicines needed in the health system.
What condition does Metoprolol Tartrate treat?
Metoprolol Tartrate is a prescription medication used for:
- Lowering high blood pressure
- Controlling arrhythmias or irregular heartbeat
- Preventing angina attacks or chest pain
- Improve the likelihood of survival after a heart attack
- Prevent further heart problems after myocardial infarction
- Reducing the symptoms of an overactive thyroid gland.
- Preventing migraines among those who frequently have migraine attacks
How does Metoprolol Tartrate work?
As a beta-blocker, Metoprolol works by temporarily reducing or stopping the body’s natural fight or flight responses. It works by blocking the beta receptors found in the heart from the action of norepinephrine. Norepinephrine is a hormone similar to adrenaline, produced by the adrenal glands and neurotransmitter. Together with adrenaline, this hormone increases the heart rate and the pumping of blood from the heart. It also increases the blood pressure and the blood sugar level to provide more energy to the body. Norepinephrine acts on the receptors on the heart muscle. It constricts the blood vessels thus increases the blood pressure and blood sugar level.
Blocking the receptor allows the heart to beat slowly and less forcefully. This reduces the workload of the heart and the pressure at which blood is pumped out of the heart. At the same time, the heart gets enough supply of oxygen to meet the demand such as during an exercise thus preventing angina attacks.
Metoprolol Tartrate also controls irregular heartbeat because of the slower heart rate. When the heart rate slows down, electrical signals in the heart fire more regularly allowing the heart to beat normally. It’s the overall effect on the heart and blood circulation helps reduce and control the symptoms associated with an overactive thyroid gland such as tremor, sweating and racing pulse.
