In order to carry out its activity, lovastatin must be taken orally .

Action mechanism

How does Lovastatin work?

Like the other active ingredients belonging to the group of statins, lovastatin performs its cholesterol-lowering action through the inhibition of the enzyme 3-hydroxy-3-metiglutaryl coenzyme A reductase (HMG-CoA reductase). This enzyme is responsible for the conversion of 3-hydroxy-3-methylglutaryl coenzyme A into mevalonate, a fundamental precursor in the biosynthesis of sterols, including cholesterol.

Furthermore, this active ingredient is able to:

  • Encourage the increase in the number of LDL receptors on the cell surface, consequently leading to an increase in LDL uptake and catabolism.
  • Reduce plasma triglyceride levels.

Method of use and Posology

How to take Lovastatin

Lovastatin is available as tablets to be swallowed whole with the help of a little water. The tablets should NOT be taken on an empty stomach, but during dinner . If the doctor has prescribed two doses a day, the drug should be taken in the morning and in the evening, always on a full stomach .

The exact dosage (dose and time of intake) of lovastatin must be established by the doctor for each patient. However, the doses usually used in therapy are as follows:

  • Treatment of hypercholesterolemia : the usual starting dose is 10 mg of lovastatin per day, to be taken in the evening during a meal. Afterwards, the amount of active ingredient to be taken can be increased by the doctor up to a maximum of 40 mg a day.
  • Treatment of hypercholesterolemia in the presence of ischemic heart disease : the usual starting dose used is 20 mg lovastatin per day, to be taken in the evening during the meal. Thereafter, the dosage can be increased by the doctor up to a maximum of 80 mg per day.

In the presence of particular pathologies or in the case of concomitant intake of other drugs, the doctor may decide to decrease the dose of the active ingredient administered.

Please note

Before starting treatment with lovastatin it is necessary to adopt a diet low in cholesterol which must then be maintained even during treatment with the active ingredient in question.
