Study Overview
=================
Brief Summary
-----------------
The objective of this study was to assess the single-dose bioequivalence of KUDCO's and Wyeth Pharmaceuticals' (Protonix) 40 mg pantoprazole sodium delayed-lease tablets, under fed conditions.

Detailed Description
-----------------
This was an open-label, randomized, fully replicated crossover, 2-sequence bioequivalence study under fed conditions.

Medically healthy subjects with clinically normal laboratory profiles, vital signs, and ECG. Females of childbearing potential were either sexually inactive (abstinent) for 14 days prior to the first dose and throughout the study, or using one of the following acceptable birth control methods: Surgically sterile (bilateral tubal ligation, hysterectomy, bilateral oophorectomy) 6 months minimum. Intrauterine device (IUD) in place for at least 3 months. Barrier method (condom, diaphragm) with spermicide for at least 14 days prior to the first dose and throughout the study. Surgical sterilization of the partner (vasectomy for 6 months minimum). Hormonal contraceptives for at least 3 months prior to the first dose of the study. Gave voluntary written informed consent to participate in the study. Exclusion Criteria: History or presence of significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, or psychiatric disease. In addition, history or presence of: Alcoholism or drug abuse within the past 2 years; Hypersensitivity or idiosyncratic reaction to pantoprazole, omeprazole, or any other substituted benzimidazole proton-pump. inhibitors. Females who were pregnant or lactating. History of tobacco use or use of products containing nicotine (i.e., smoking cessation aids such as nicotine gum or patches) within the 6 months prior to the first dose. Subjects who tested positive at screening for human immunodeficiency virus (HIV) antibody screen, hepatitis B surface antigen screen (HbsAg), or hepatitis C antibody screen (HCV). Treatment with any known enzyme-altering drugs (barbiturates, phenothiazines, cimetidine, etc.) within 30 days prior to the first dose. Difficulty in swallowing medication or any gastrointestinal disease that would affect the drug absorption. Subjects who had been on a special diet (for whatever reason) during the 28 days prior to the first dose and throughout the study. Subjects who, through completion of the study, would have donated in excess of: 500 mL of blood in 14 days; 1500 mL of blood in 180 days; 2500 mL of blood in one years. Subjects who participated in another clinical trial with 28 days prior to the first dose.
