Metoprolol which is more commonly known by its brand names of lopressor and toprol xl is a medication used to fight high blood pressure. Metoprolol medicine works to block the sympathetic nervous system, as do other beta-blocking drugs. these nerves are what control the rate of a persons heart beat, and by slowing or blocking these nerves metoprolol can slow the heart beat rate which slows the pressure in which the blood is pumped. This give metoprolol two effective uses, lowering high blood pressure and helping those with an unusually rapid heart beat. Metoprolol is also effective in the treatment of angina which is a pain caused when the heart needs more oxygen. Metoprolol is also known to help in patients with migraines and specific types of tremors.
The general dosage of metoprolol tablets is 50 mg, 100 mg, and 200 mg and should be taken before meals or at bedtime. Metoprolol does have some interaction problems with other medical issues that should be looked out for and of course make sure you doctor knows about and underlying conditions you may have before he prescribes metoprolol to you. In patients with asthma, chronic bronchitis, or emphysema, you could see a worsening of these conditions. If you have an unusually slow heart rate and/or heart blockages that slow the blood flow could possibly lower it more and bring it to a dangerously low level. Do not take metoprolol with calcium channel blockers or digoxin because it too can cause the blood pressure and heart rate to fall to dangerously low levels. Commonly to come off of metoprolol you are weaned down gradually over the period of a couple weeks time, it is strongly advised not to stop due to increased risk of heart attack if dropped too fast.
