For Pharmacists:

Medicine Name: Cadwin

Brand: Cadwin
Active Ingredient(s):

• Amlodipine Besylate (5 mg)
• Atorvastatin Calcium (10 mg)

Indications:

• Treatment of hypertension and angina.
• Reduction of cholesterol and triglyceride levels in patients at risk for cardiovascular disease.

Pharmacodynamics:

• Mechanism of Action:
  • Amlodipine: Inhibits calcium influx in vascular smooth and cardiac muscles, leading to vasodilation and reduced blood pressure.
  • Atorvastatin: Inhibits HMG-CoA reductase, decreasing cholesterol production in the liver.
• Pharmacological Effects:
  • Improves blood flow and reduces blood pressure (amlodipine).
  • Lowers lipid levels and reduces cardiovascular risks (atorvastatin).
• Receptor Binding:
  • Amlodipine: High affinity for L-type calcium channels.
  • Atorvastatin: Selective inhibition of HMG-CoA reductase enzyme in liver cells.

Pharmacokinetics:

• Amlodipine:
  • Absorption: Slow but complete; bioavailability ~60–80%.
  • Metabolism: Metabolized by the liver.
  • Half-Life: 30–50 hours.
  • Elimination: Excreted in urine and feces.
• Atorvastatin:
  • Absorption: Rapid absorption with bioavailability ~14%.
  • Metabolism: Liver metabolism via CYP3A4.
  • Half-Life: 14 hours (active metabolites ~20–30 hours).
  • Elimination: Primarily excreted in bile.

Dosage and Administration:

• Adults: One tablet (5/10 mg) daily. Dosage adjustments may be required based on clinical response.
• Special Populations:
  • Use cautiously in elderly patients or those with hepatic impairment.

Contraindications:

• Hypersensitivity to amlodipine, atorvastatin, or excipients.
• Active liver disease or unexplained persistent liver enzyme elevations.
• Pregnancy and lactation (atorvastatin is contraindicated).

Warnings and Precautions:

• Monitor liver function and lipid profiles regularly.
• Use cautiously in patients with renal impairment or those at risk for myopathy.
• Discontinue atorvastatin if significant muscle symptoms or rhabdomyolysis occur.

Drug Interactions:

• With Other Medications:
  • Increased risk of myopathy when combined with fibrates or niacin.
  • CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) increase atorvastatin levels.
• Drug-Food Interactions:
  • Avoid grapefruit juice, as it increases atorvastatin plasma concentrations.

Adverse Reactions:

• Common: Dizziness, headache, peripheral edema, nausea, or muscle pain.
• Serious: Liver dysfunction, rhabdomyolysis, or severe allergic reactions.

Therapeutic Effects:

• Effectively lowers blood pressure and lipid levels.
• Reduces cardiovascular morbidity and mortality.

Storage:

• Store at 20–25°C, away from direct sunlight and moisture.

Packaging:

• Supplied in blister packs containing 7 tablets (5/10 mg each).

Clinical Considerations:

• Pregnancy Category: X (Contraindicated during pregnancy).
• Lactation: Not recommended; avoid during breastfeeding.
• Pediatric Use: Safety and efficacy not established.
• Geriatric Use: Generally safe with proper monitoring.

Conclusion:

Cadwin 5/10 mg combines amlodipine and atorvastatin to provide comprehensive management of hypertension and hyperlipidemia. With once-daily dosing, it offers convenience and efficacy in reducing cardiovascular risks. Always follow your healthcare provider’s guidance for optimal results.
