In fact, none of the individual animals on the evogram is the direct ancestor of any other, as far as we know. That's why each of them gets its own branch on the family tree. Hippos are large and aquatic, like whales, but the two groups evolved those features separately from each other.
Pitavastatin (usually as a calcium salt) is a member of the blood cholesterol lowering medication class of statins, marketed in the United States under the trade name Livalo, and in European Union and Russia under the trade name Livazo.
Pravastatin reduces levels of bad cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing levels of good cholesterol (high-density lipoprotein, or HDL). Pravastatin is used to lower cholesterol and triglycerides (types of fat) in the blood. Pravastatin is also used to lower the risk of stroke, heart attack, and other heart complications in people with diabetes, coronary heart disease, or other risk factors. Pravastatin is used in adults and children who are at least 8 years old. Pravastatin may also be used for purposes not listed in this medication guide.
