This phenomenon is known as gravity. More massive objects have a stronger pull than less massive objects. This is why you weigh more on larger, more massive planets like Jupiter and less on smaller, less massive planets like Mars. The mass of an object depends not only on its size, but also its composition.
Nifedipine is approved to control high blood pressure and angina (chest pain). Classified as a calcium-channel blocker, nifedipine blocks the passage of calcium into cardiac and smooth muscle, like those of the uterus. And calcium is needed for the uterus to contract. Nifedipine is one of the most widely used and studied medications among the calcium-channel blockers to suppress preterm contractions. But the use of tocolytics is controversial. In 80 percent of women with suspected preterm labor, early delivery will not occur.
What is Cardene (nicardipine)? Nicardipine is a calcium channel blocker. Nicardipine relaxes (widens) your blood vessels, which makes it easier for the heart to pump and reduces its workload. Nicardipine is used to treat hypertension (high blood pressure) and angina (chest pain). Nicardipine may also be used for purposes not listed in this medication guide.
