A Pharmacodynamic Study Comparing Zegerid® and Prilosec OTC® (CL2007-17 )(P07813)(COMPLETED)

February 20, 2015 updated by: Bayer

Randomized, Crossover Pharmacodynamic Study Comparing the Effects of Zegerid® (20 mg Omeprazole/Sodium Bicarbonate) and Prilosec OTC® (20 Mg-equivalent Omeprazole)

Open-label randomized crossover design studies. 60 participants will be evaluated on Day 1 to compare effects on stomach acid; 30 participants will continue treatment for 7 days and will have repeat evaluations at Day 7. The other 30 participants will receive a single administration of sodium bicarbonate.

Detailed Description

Enrolled participants were divided into 2 groups, with 30 participants in each group.

Group 1: This group was randomized into a 2-way crossover design with an added third period. These participants received single administrations (day 1 dosing only) of Zegerid Powder for Oral Suspension, and Prilosec OTC (both at a 20 mg omeprazole dose), in a 2-way randomized order, with a minimum of a 2-week washout period between treatment legs. Following completion of the 2-way crossover study, and a subsequent washout period (minimum of 2 weeks), all participants then received a single administration of sodium bicarbonate (at same dose as contained in Zegerid Powder for Oral Suspension) in Period 3. This group underwent a 24-hour intragastric pH study on each of the 3 dosing occasions.

Group 2: This group was randomized into a 2-way crossover design in which they received 7 days administration of Zegerid Powder for Oral Suspension and Prilosec OTC tablets, respectively. As with the prior group, there was a minimum of a 2-week washout period between treatment legs. Participants assigned to this treatment group also underwent 24-hour intragastric pH recordings on the days on which they received their 1st and last (7th) dose of the two treatment drugs.

In addition to the above detailed procedures, all participants (both groups) underwent a 24-hour baseline intragastric pH study prior to starting their randomized treatments. This study design enabled all 60 participants to be evaluated for effects of the first dose of Prilosec OTC and Zegerid Powder for Oral Suspension on change in intragastric pH during the subsequent 24-hour period following the first dose.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Median 24-hour Intragastric pH on the 7th Day of Drug Administration
Time Frame: Baseline and 7 days
The change from Baseline in median pH was calculated as: median pH on Day 7 minus median pH at Baseline. PH measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
Baseline and 7 days
