Tiazac is a calcium ion flux inhibitor, or a slow channel blocker. The drug works specifically on vascular smooth muscle and heart muscle, and helps store calcium to widen the blood vessels.
- decreasing high blood pressure (hypertension)
- decreasing chest pain caused by lack of blood to the heart (angina)
What are some important things I should know about Tiazac?
If you think you may have high blood pressure or angina, contact your doctor. It’s wise to be checked for these conditions on a regular basis, especially as you age. Tiazac may be one treatment your doctor discusses with you.
However, according to the FDA, Tiazac can cause harmful side effects, such as:
- cardiac conduction disease, or irregularly slow or fast heart beats that can lead to death
- congestive heart failure, which occurs when the heart can’t pump enough blood to the body’s organs
- hypotension, which is the opposite of hypertension, and is recognized by extremely low blood pressure
- acute hepatic injury, or liver damage
- ventricular premature beats, or abnormalities in the heart rhythms
If you are injured because of Tiazac, contact a personal injury attorney immediately.
High blood pressure, or hypertension, is caused by too much blood being forced through arteries that are too small. This can put serious strain on the heart. High blood pressure can be caused by a number of factors, such as genetics, pregnancy, overweight, increased age, inactivity, excessive drinking, drug use, smoking and high fat foods. As many as one in three people have high blood pressure, and many do not know it. Your doctor can help you test for high blood pressure, and it is important to treat it immediately, because it can lead to heart attack and stroke.
Angina, or chest pain, is caused when blood vessels are so restricted that there is a lack of blood flowing to the heart. This leads to serious pain and injury, and can lead to death. Blood vessels are restricted because of high blood pressure and plaque build up.
Tiazac can cause dangerous drug interactions and harmful allergic reactions. Tiazac can also cause heart failure, liver injury or extremely low blood pressure.
