Basic Drug Info
Drug Name:FAMOTIDINE
Manufacturer:Dr.Reddy's Laboratories Limited
Other Info:

In adult patients with moderate (creatinine clearance < 50 mL/min) or severe (creatinine clearance < 10 mL/min) renal insufficiency, the elimination half-life of famotidine is increased.

For patients with severe renal insufficiency, it may exceed 20 hours, reaching approximately 24 hours in anuric patients.

Since CNS adverse effects have been reported in patients with moderate and severe renal insufficiency, to avoid excess accumulation of the drug in patients with moderate or severe renal insufficiency, the dose of famotidine may be reduced to half the dose or the dosing interval may be prolonged to 36-48 hours as indicated by the patient's clinical response.Based on the comparison of pharmacokinetic parameters for famotidine in adults and pediatric patients, dosage adjustment in pediatric patients with moderate or severe renal insufficiency should be considered.



Clinical Trials:


Indications and Usage

Famotidine is indicated in:1.

Short-term treatment of active duodenal ulcer.

Most adult patients heal within 4 weeks; there is rarely reason to use famotidine at full dosage for longer than 6 to 8 weeks.

Studies have not assessed the safety of famotidine in uncomplicated active duodenal ulcer for periods of more than eight weeks.2.

Maintenance therapy for duodenal ulcer patients at reduced dosage after healing of an active ulcer.

Controlled studies in adults have not extended beyond one year.3.

Short-term treatment of active benign gastric ulcer.

Most adult patients heal within 6 weeks.

Studies have not assessed the safety or efficacy of famotidine in uncomplicated active benign gastric ulcer for periods of more than 8 weeks.4.

Short-term treatment of gastroesophageal reflux disease (GERD).

Famotidine is indicated for short-term treatment of patients with symptoms of GERD (see CLINICAL PHARMACOLOGY IN ADULTS, Clinical Studies).Famotidine is also indicated for the short-term treatment of esophagitis due to GERD including erosive or ulcerative disease diagnosed by endoscopy (see CLINICAL PHARMACOLOGY IN ADULTS, Clinical Studies).5.

Treatment of pathological hypersecretory conditions (e.

g., Zollinger-Ellison Syndrome, multiple endocrine adenomas ) (see CLINICAL PHARMACOLOGY IN ADULTS, Clinical Studies).
Duodenal Ulcer -- A PEPTIC ULCER located in the DUODENUM.

Ulcer -- A lesion on the surface of the skin or a mucous surface, produced by the sloughing of inflammatory necrotic tissue.

Gastroesophageal reflux disease -- Retrograde flow of gastric juice (GASTRIC ACID) and/or duodenal contents (BILE ACIDS; PANCREATIC JUICE) into the distal ESOPHAGUS, commonly due to incompetence of the LOWER ESOPHAGEAL SPHINCTER. Gastric regurgitation is an extension of this process with retrograde flow into the PHARYNX or MOUTH.

Symptoms -- An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.

Esophagitis -- INFLAMMATION, acute or chronic, of the ESOPHAGUS caused by BACTERIA, chemicals, or TRAUMA.

Disease -- A definite pathologic process with a characteristic set of signs and symptoms. It may affect the whole body or any of its parts, and its etiology, pathology, and prognosis may be known or unknown.

Zollinger-Ellison syndrome -- A syndrome that is characterized by the triad of severe PEPTIC ULCER, hypersecretion of GASTRIC ACID, and GASTRIN-producing tumors of the PANCREAS or other tissue (GASTRINOMA). This syndrome may be sporadic or be associated with MULTIPLE ENDOCRINE NEOPLASIA TYPE 1.

Multiple Endocrine Neoplasia -- group of specific, familial syndromes characterized by simultaneous neoplastic transformation of multiple endocrine tissues, typically the parathyroid glands, pancreatic islets, and anterior pituitary.

Contraindications

Hypersensitivity to any component of these products.

Cross sensitivity in this class of compounds has been observed.

Therefore, famotidine should not be administered to patients with a history of hypersensitivity to other H2 receptor antagonists.
Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.
