A Relative Bioavailability Study of 20 mg Famotidine Tablets Under Fasting Condition

Study Overview
=================
Brief Summary
-----------------
The study was conducted as an open-label, balanced, randomized, two-treatment, two-period, two-sequence, single-dose, crossover, bioavailability study comparing famotidine tablets, USP 20 mg manufactured by OHM Laboratories with Pepcid® AC Acid reducer famotidine tablets 20 mg (containing famotidine 20 mg) distributed by Johnson & Johnson. Merck Consumer Pharmaceutical Co. Fort Washington, PA 19034 USA under fasting conditions.

Detailed Description
-----------------
Following an overnight fast of at least 10 hour, a single oral dose of famotidine tablets, USP 20 mg or Pepcid® AC Acid reducer famotidine tablets 20 mg (containing famotidine 20 mg) was administered during each period of the study, along with 240 mL of drinking water at ambient temperature and under supervision of trained study personnel. During the course of the study, safety parameters assessed were vital signs, clinical examination, medical history and clinical laboratory safety tests (hematology, biochemical parameters, serology and urine analysis) at baseline. Adverse event monitoring was done throughout the study. Laboratory parameters of hematology and biochemistry (except blood glucose and cholesterol) were repeated at the end of the study for all the subjects.

The subject had evidence of organ dysfunction or any clinically significant deviation from the normal, in physical or clinical determinations. Investigations with blood samples of the subject showed presence of disease markers of HIV 1 or 2, Hepatitis B or C viruses or syphilis infection. Investigations with blood samples of the subject showed the presence of values which are significantly different from normal reference range and/or judged clinically significant for haemoglobin, total white blood cells count, differential WBC count or platelet count. Positive for urinary screen testing of drugs of abuse (opiates or cannabinoids) Investigations with blood samples of the subject showed the presence of values which are significantly different from normal reference range and/or judged clinically significant for serum creatinine, blood urea, serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), serum alkaline phosphatase, serum bilirubin, plasma glucose or serum cholesterol. Investigations with urine samples of the subject showed clinically abnormal chemical and microscopic examination of urine defined as presence of RBC, WBC (>4/HPF), epithelial cells (>4/HPF), glucose (positive) or protein (positive). Clinically abnormal ECG or Chest X-ray. The subject had history of serious gastrointestinal, hepatic, renal, pulmonary, cardiovascular, neurological or haematological disease, diabetes or glaucoma. The subject had history of any psychiatric illness, which may impair the ability to provide written informed consent.
