Simvastatin, sold under brand names including Zocor, is a medicine which is part of a class of medicines that lower lipid levels. Collectively, this medicinal class is referred to as statins and Simvastatin works by lowering total cholesterol levels in the blood including LDL cholesterol, sometimes referred to as "bad" cholesterol.
Simvastatin also works to increase levels of HDL ("good") cholesterol which means that by reducing LDL and increasing HDL levels, Simvastatin can help prevent arterial plaque formation which over time can make an individual at risk of a cardiac event such as cardiac arrest.
Simvastatin was developed by Merck in 1992 and is part of the list of essential medicines considered by the World Health Organisation to offer a high level of effectiveness and safety. By reducing LDL cholesterol very effectively, Simvastatin is considered critical for managing health outcomes in the modern world.
Simvastatin is typically prescribed to adults of both sexes who have a persistent issue with elevated levels of LDL cholesterol where diet and exercise alone have either proven ineffective or else where the patient's ability to make changes to their lifestyle requires a pharmacological solution.
Simvastatin should be taken exactly as described by your doctor but in general it is dosed once daily in the morning but with the dose taken varying significantly based on the patient's medical history. However, very high doses are usually only used in those with very high cholesterol levels and who are therefore most at risk of a heart attack.
