What drugs are commonly used to lower the risk of heart and circulatory diseases?

medications include:

statins such as atorvastatin (Lipitor), pravastatin sodium (Pravachol), and simvastatin (Zocor)

bile acid resins such as cholestyramine

cholesterol absorption inhibitors such as ezetimibe (Zetia)

fibric acid derivatives such as fenofibrate (Tricor)

nicotinic acid such as niacin (Niacor)

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
