Lovastatin

What is Lovastatin?

Lovastatin, available at Medzino under the brand name Mevacor, is a drug used to lower cholesterol. Although cholesterol is important for the normal functioning of our cells, high levels of cholesterol in the blood may cause atherosclerosis, a condition in which plaques containing cholesterol form within the arteries. These plaques block our arteries and reduce the blood flow, which in turn can cause angina (chest pain), heart attacks, strokes and general heart disease if the arteries that supply the heart with blood become clogged. Doctors at Medzino can issue a prescription of Lovastatin to treat cholesterol if you are suitable.

What are statins?

Lovastatin belongs to the class of drugs called “statins”. Statins work by blocking the enzyme in the liver that is responsible for producing cholesterol. This enzyme is called hydroxy-methylglutaryl-coenzyme A reductase (HMG-CoA reductase).  Indeed, there are two sorts of cholesterol: blood cholesterol, which comes from the liver, and dietary cholesterol, which comes from the foods we eat that are high in cholesterol. If we eat too many saturated and trans fats, our blood cholesterol will rise significantly. You find saturated and trans fats in foods such as red meat, butter, cheese, cream, whole milk, palm oil, coconut oil. In the blood, statins help reduce total cholesterol and LDL cholesterol commonly referred to as “bad” cholesterol. It is important to keep your LDL levels low, as it causes atherosclerosis and coronary artery disease. Statins also work by increasing your HDL levels, commonly known as “good” cholesterol, which helps lowering LDL levels and thus reduces risks of heart disease. However, taking this medicine alone is not the ideal solution to treat high cholesterol. Instead, Lovastatin should be taken as a complement to a healthy and balanced diet low in fat and cholesterol, weight-loss and exercise low.

How does Lovastatin work?

Lovastatin is an HMG-CoA Reductase inhibitor. HMG-CoA Reductase is an enzyme that is responsible for cholesterol synthesis in the liver. Lovastatin blocks this enzyme therefore reducing the amount of cholesterol the liver can make.  It has been shown to reduce levels of "bad cholesterol" also known as LDL.  For this reason, it has been used to prevent stroke and heart attacks.

How effective is Lovastatin?

The efficacy of lovastatin depends on the dose as well as several other factors, however it has been shown to reduce LDL about 30 to 50%.

The recommended dosage range of Lovastatin is 10-80mg daily. Lovastatin is to be taken as prescribed by your doctor, preferably in the evening for a more effective result. The usual recommended starting dose is 20mg once a day with the evening meal, but your doctor may gradually increase your dose if considered necessary. The maximum recommended dose in 80mg a day.

Swallow your tablet orally (by mouth) with a glass of water. Do not chew or crush your tablet. Take your medicine at the same time of the day to help you remember your dosage. If you forget to take your daily dosage, take it as soon as you remember. If, however, it’s almost time to take your next dosage, skip the one you forgot and take the dosage that is due soon. Do not take a dose twice to make up for the one you forgot. Do not interrupt your treatment without consulting your doctor, even if you feel better.

How to take Lovastatin

Lovastatin is taking once daily with the evening meal or at bedtime.  This is because it works better when given later in the day.  The dose can be adjusted based on the response of blood cholesterol levels. 

What should I do if I miss a dose?

If you miss a dose of lovastatin is still within the same day, you can take the missed dose.  However if it is almost time for the next dose or more than 12 hours have passed, just skip the missed dose and resume the next dose when it would be due.  Missing one dose is not likely to affect the efficacy of the medication.
