Lescol Exel (Fluvastatin Sodium)

Lescol Exel, a lipid‑lowering agent, is indicated for conditions that involve abnormal cholesterol metabolism.

• Hypercholesterolemia: reduces low‑density lipoprotein (LDL) and total cholesterol concentrations.
• Primary prevention of cardiovascular disease: lowers the risk of first‑time heart attack or stroke in at‑risk adults.
• Secondary prevention of cardiovascular disease: helps prevent recurrent events in patients with established coronary artery disease.

• Fluvastatin Sodium inhibits the enzyme HMG‑CoA reductase, the rate‑limiting step in hepatic cholesterol synthesis. This inhibition decreases intracellular cholesterol, prompting up‑regulation of LDL receptors on hepatocyte surfaces, which enhances clearance of circulating LDL particles and lowers overall plasma cholesterol levels.

Fluvastatin Sodium may cause a range of adverse reactions, from mild to serious.

Common Side Effects

• Headache: mild to moderate pain often occurring early in therapy.
• Myalgia: muscle aches without weakness.
• Abdominal pain: discomfort in the stomach area.
• Nausea: feeling of sickness, sometimes with loss of appetite.
• Constipation: infrequent bowel movements.

Serious or Rare Side Effects

• Rhabdomyolysis: severe muscle breakdown that can lead to kidney injury.
• Elevated liver enzymes: indicating possible hepatic injury.
• Myopathy: muscle weakness with elevated creatine kinase.
• Severe allergic reaction: rash, swelling, or anaphylaxis.
• Hepatotoxicity: rare cases of liver failure.

Before initiating therapy with Lescol Exel, several safety considerations are recommended.

• Liver function monitoring: obtain baseline tests and repeat periodically.
• Renal impairment assessment: adjust use in patients with severe kidney disease.
• Drug‑induced myopathy vigilance: educate patients to report unexplained muscle pain or weakness.
• Pregnancy and lactation counseling: avoid use unless benefits outweigh risks.
• Concomitant medication review: assess for agents that may increase statin exposure.
• Store at ambient temperature: keep below 25 °C, retain in original packaging, and protect from moisture.

Fluvastatin Sodium can interact with several medicines, altering its safety or effectiveness.

Major Interactions (Avoid)

• Strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin): markedly increase fluvastatin plasma levels.
• Gemfibrozil: heightened risk of myopathy and rhabdomyolysis.
• HIV protease inhibitors (e.g., ritonavir): elevate statin exposure and toxicity.

Moderate Interactions (Monitor Closely)

• Warfarin: may potentiate anticoagulant effect; monitor INR closely.
• Digoxin: possible increase in serum digoxin; check levels periodically.
