Famoloc 40 mg Tablet

Also Available :40 mg/5 ml20 mg


Famoloc 40 mg tablet is an H2 receptor antagonist. Famotidine lowers the excess acid secretion by blocking the histamine (H2) receptor and thus accelerates the ulcer healing process in the stomach. This suppresses stimulated acid output within two hours after administration for 12 hours. The affinity of Famotidine for the H2 receptor is significantly greater than those of Ranitidine or Cimetidine. Famoloc has no anti-androgenic activity and has no action on hepatic cytochrome P450 activity.

Dosage and Administration

Route of administration: Orally. 

Adult Dose: 

  • In gastric and duodenal ulcer: Famotidine 40 mg at night. 
  • Duodenal ulcer: The recommended initial dose is 40 mg Famotidine at night. Treatment should be continued for four to eight weeks. In most patients, healing occurs on this regimen within four weeks. In those patients whose ulcers have not entirely healed after four weeks, a further four-week period of treatment is recommended. 
  • Maintenance therapy: For preventing the recurrence of duodenal ulceration, a reduced dose of 20 mg Famotidine at night is recommended. This 20 mg maintenance dose has been continued effectively in clinical studies for 12 months. 
  • Gastric ulcer: The recommended dose is 40 mg Famotidine at night. Treatment should be continued for four to eight weeks unless endoscopy reveals earlier healing. 
  • Gastroesophageal Reflux Disease (GERD): 
  • Symptomatic: 20 mg b.i.d 
  • Erosive: 40 mg b.i.d 
  • Maintenance Dose: 20 mg b.i.d 
  • Zollinger-Ellison Syndrome: Patients without prior antisecretory therapy should be started on 20 mg Famotidine every six hours. The dosage should then be adjusted to individual responses. Dosage of up to 40 mg daily in divided doses has been used for up to one year without the development of significant adverse effects. Patients receiving another H2 -antagonist may be switched directly to Famotidine at a dose higher than that recommended few cases. The starting dose will depend on the severity of the condition and the last dose of H2 -antagonist previously used. 
  • Dosage adjustment in renal impairment: Since Famotidine is excreted primarily by the kidney; caution should be observed in patients with impaired renal function. A reduction in daily doses should be considered if creatinine clearance falls to or below 30 ml/min, the dose should be reduced to 20 mg per day.
