For Pharmacists:

Medicine Name: Adalat RTD
Brand: Adalat
Active Ingredient(s): Nefidipine 20 mg

Indications:

• Treatment of hypertension.
• Chronic stable angina.
• Certain vascular disorders.

Pharmacodynamics:

• Mechanism of Action:
  Nefidipine is a calcium channel blocker that inhibits the influx of calcium ions into smooth muscle and myocardial cells, reducing vascular resistance and myocardial oxygen demand.
• Pharmacological Effects:
  • Relaxes arterial smooth muscle, leading to vasodilation and reduced blood pressure.
  • Reduces frequency and intensity of angina attacks.
• Receptor Binding:
  Binds selectively to L-type calcium channels in vascular smooth muscle and myocardial tissue.

Pharmacokinetics:

• Absorption: Rapidly absorbed, with peak plasma concentration within 30-60 minutes.
• Distribution: Extensive tissue distribution, with a high volume of distribution.
• Metabolism: Hepatic metabolism via the CYP3A4 pathway.
• Elimination: Primarily excreted via urine.
• Half-Life: Approximately 6-8 hours.
• Effect of Food: Food slows down the absorption of nifedipine, reducing peak plasma concentration.

Dosage and Administration:

• Adults:
  • 20 mg once daily, adjusted based on patient’s blood pressure and response.
• Special Populations:
  • Monitor closely in patients with hepatic impairment or older adults.

Contraindications:

• Severe hypotension, shock.
• Known hypersensitivity to nifedipine or its excipients.
• Unstable angina or acute myocardial infarction.

Warnings and Precautions:

• Use with caution in:
  • Patients with liver impairment or heart failure.
  • Patients at risk of hypotension.

Drug-Drug Interactions:

• Increased risk of hypotension when combined with other antihypertensive drugs.
• Grapefruit juice can increase nifedipine levels, potentially causing toxicity.

Drug-Food Interactions:

• Grapefruit juice can enhance nifedipine absorption and effects.

Adverse Reactions:

• Common: Dizziness, headache, flushing, peripheral edema.
• Serious: Severe hypotension, arrhythmias, peripheral swelling.

Therapeutic Effects:

• Effective in lowering blood pressure and relieving angina by relaxing vascular smooth muscle and reducing myocardial oxygen demand.

Storage:
Store at 15-30°C, protected from light and moisture.

Packaging:
Available in blister packs of 30 tablets.

Clinical Considerations:

• Pregnancy Category: C (use only if necessary).
• Lactation Category: Use with caution.
• Pediatric Use: Not recommended for children.
• Geriatric Use: Monitor closely for adverse effects in elderly patients.

Conclusion:

Adalat RTD 20 mg Tab is a sustained-release calcium channel blocker used for managing hypertension and angina. Regular monitoring of blood pressure and heart function is crucial for safe use.
