Product information

Simvastatin is a drug indicated for the treatment of high cholesterol, in those who have been unable to lower levels through diet and exercise alone. It is available in varying dosages, and a course is most typically initiated on a lower strength of 10 or 20mg. This is taken as one tablet, once a day. Simvastatin is made by Teva, and is the generic version of the product otherwise known as Zocor. It contains the same active ingredient, and behaves in the same way in the body; to reduce cholesterol. The drug is also available as an oral suspension fluid.

  2. Simple to take tablet or oral suspension fluid
  3. Different doses available

What a large number of people are unaware of is that cholesterol, even though it is a fat, is a substance which the body requires to function normally. The main processor of cholesterol in the body is the liver, where it is taken up by proteins to form ‘lipoproteins’, before being carried around via the bloodstream. Once delivered to their destination, these fats play an important part in the formation of healthy cell structures.

However, it is an abundant presence of one form of these lipoproteins (low density, or LDLs) which causes problems. In large numbers, LDLs can swamp the arteries and gather there, causing them to become narrow. The less room there is for blood to get through the arteries, the more likely it is that illnesses related to poor circulation, such as stroke, angina or heart attack, will occur.

Some people may be genetically predisposed to high cholesterol, and others may experience it as a consequence of another illness, such as diabetes. But lifestyle factors can be a major contributor too. People who consume a lot of saturates in their diet, smoke, drink large amounts of alcohol on a frequent basis, or are physically inactive, are much more likely to get high cholesterol.

In those instances where taking the appropriate measures to rectify these causes (such as reducing fat and alcohol intake, or introducing a programme of light exercise) has not produced results, medication may be suggested by a doctor. This is more typically prescribed in the form of a statin.

What statins do is interfere with the processes in the liver which produce cholesterol. In the case of Simvastatin, an active ingredient of the same name does this by inhibiting the workings of an enzyme in the liver, which is responsible for turning out cholesterol. By inhibiting this function, the levels of cholesterol in the body become lowered, thereby offsetting the risk of associated serious illnesses.
