Things worth knowing about "Pravastatin"

Pravastatin is a prescription medication used to lower elevated cholesterol levels and reduce the risk of cardiovascular disease.

What is Pravastatin?

Pravastatin is a prescription medication belonging to the statin drug class, used to treat elevated cholesterol levels (hypercholesterolaemia) and to prevent cardiovascular events such as heart attacks and strokes. It is one of the most widely prescribed medications globally and is approved for both primary and secondary cardiovascular prevention.

Indications

Pravastatin is indicated for:

Primary hypercholesterolaemia: elevated LDL cholesterol (so-called "bad" cholesterol) when diet and lifestyle changes are insufficient
Mixed dyslipidaemia: a combination of elevated LDL, elevated triglycerides, and low HDL cholesterol
Primary prevention: reducing the risk of heart attack and stroke in patients at increased cardiovascular risk
Secondary prevention: reducing the risk of further cardiovascular events in patients who have already experienced a heart attack or have coronary artery disease
Familial hypercholesterolaemia in children and adolescents aged 8 years and older

Mechanism of Action

Pravastatin acts as a competitive inhibitor of the enzyme HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase), which is the rate-limiting step in hepatic cholesterol biosynthesis. By inhibiting this enzyme, pravastatin reduces cholesterol production in the liver. In response, the liver upregulates LDL receptors on its surface, leading to increased clearance of LDL cholesterol from the bloodstream. This results in a significant reduction of plasma LDL cholesterol. Notably, pravastatin is not metabolised via the cytochrome P450 (CYP450) pathway, which reduces its potential for drug interactions compared to other statins.

Dosage and Administration

Pravastatin is taken orally as a tablet, typically once daily. It can be taken with or without food. Although the cholesterol synthesis rate is highest at night, pravastatin does not strictly require evening administration unlike some other statins.

Adults: usually 10–40 mg per day; up to 80 mg in some cases
Children (8–13 years): 20 mg per day
Adolescents (14–18 years): 40 mg per day
Dose adjustments may be necessary in patients with renal impairment or liver disease

Drug therapy should always be accompanied by a low-cholesterol diet and a healthy lifestyle.

Side Effects

Pravastatin is generally well tolerated. Possible side effects include:

Common Side Effects

Headache
Fatigue
Gastrointestinal complaints (e.g., nausea, diarrhoea, constipation)
Muscle pain (myalgia)

Rare but Serious Side Effects

Myopathy (muscle damage) and, in rare cases, rhabdomyolysis (severe muscle breakdown that can impair kidney function) – patients should seek immediate medical attention if they experience unexplained muscle pain or weakness
Hepatic enzyme elevations and liver dysfunction
Hypersensitivity reactions

Drug Interactions

Because pravastatin is not metabolised via the hepatic CYP450 system, it has a lower interaction potential than many other statins. However, some clinically relevant interactions exist:

Ciclosporin: increases pravastatin plasma levels; dose adjustment required
Cholestyramine and colestipol (bile acid sequestrants): reduce pravastatin absorption; a dosing interval of at least 1 hour is recommended
Anticoagulants (e.g., warfarin): possible enhancement of anticoagulant effect
Fibrates and nicotinic acid: increased risk of muscle damage when combined

Contraindications

Active liver disease or persistently elevated liver enzyme levels of unknown origin
Pregnancy and breastfeeding (teratogenic potential)
Hypersensitivity to pravastatin or any of the excipients
