Famoloc (Famotidine): An H2-Receptor Antagonist

Famoloc contains Famotidine, a histamine H2-receptor antagonist. It works by completely inhibiting the action of histamine on the H2-receptors of the stomach's parietal cells, which are responsible for gastric acid secretion. This leads to the inhibition of basal and stimulated gastric acid secretion. Famoloc is indicated for the treatment of various ulcer conditions, reflux esophagitis, Zollinger-Ellison syndrome, and gastritis.

How Famoloc Works (Pharmacology)

Famotidine blocks histamine receptors in the stomach:

• H2-Receptor Antagonist: Famotidine is a competitive H2-receptor antagonist. It binds to the H2-receptors on the gastric parietal cells.
• Inhibits Gastric Acid Secretion: By blocking these receptors, it prevents histamine from stimulating acid production. This results in the inhibition of basal, overnight, and pentagastrin-stimulated gastric acid secretion.
• Slowly Reversible Action: The drug dissociates slowly from the H2-receptors, providing a prolonged inhibitory effect on acid secretion.

Key Indications & Benefits

Famoloc is indicated for the treatment of:

• Gastric, duodenal, and anastomotic ulcers.
• Reflux esophagitis.
• Zollinger-Ellison syndrome.
• Acute and chronic gastritis.
• Upper gastro-intestinal hemorrhage.

Dosage & Administration

The dosage of Famoloc varies by patient age and condition.

• Adults (Tablet):
  • Ulcers/Reflux/Gastritis: 20 mg twice daily (after breakfast and supper) or 40 mg once daily at bedtime.
  • Maintenance: 20 mg once daily.
• Pediatric Patients (Powder for Suspension):
  • GERD (1-16 years): 1 mg/kg/day divided twice daily, up to 40 mg twice daily.
  • Duodenal/Peptic Ulcer (1-16 years): 0.5 mg/kg/day at bedtime or divided twice daily, up to 40 mg/day.
  • Infants (neonates to <1 year): 0.5 mg/kg/dose once or twice daily, for up to 8 weeks.
• Zollinger-Ellison Syndrome: 40 mg three times daily.

Important Considerations & Warnings

It is crucial to discuss your full medical history with your doctor before taking Famoloc.

Contraindications:

• Known hypersensitivity to any component of the drug.

Side Effects:

• Rare: Eruption, constipation, diarrhea, dry mouth, nausea, vomiting, tachycardia, high blood pressure, headache, drowsiness, or insomnia.

Pregnancy & Lactation:

• Pregnancy Category B: Use during pregnancy only if clearly needed.
• Lactation: Caution should be exercised when administered to a nursing woman.

Precautions & Warnings:

• Special Populations: Administer with care to elderly patients and those with renal failure and hepatic disorders. The dosage should be adjusted based on the patient's condition.
• Minimum Effective Dose: The drug should be used in the minimum required amount depending on the disease condition.

Drug Interactions:

• No clinically important drug interactions have been identified. Famotidine does not interact with the cytochrome P450-linked drug-metabolizing enzyme system.

Storage Conditions

Keep below 30°C, away from light and moisture. Keep out of the reach of children.
