Clinical Study Results

In a head-to-head clinical study, Prilosec OTC® had superior 24-hour acid control vs. Prevacid® 15 mg (OTC)1††

††Relative acid control (mean time pH > 4) does not imply symptom relief. The correlation of pH data to clinical outcome has not been directly established. Measured on Day 5. Not for immediate relief.

More PPIs are becoming available over-the-counter (OTC), so it's important for healthcare professionals to have accurate information and know how OTC products compare to the original Rx PPI. For instance, the tested formulation in the study is lansoprazole 15 mg. It should be noted that lansoprazole 15 mg is the same formulation as Prevacid24HR2.

Study Design

The study design for our clinical trials was randomized and double-blind.

The primary objective was to compare the 24-hour gastric acid control of omeprazole magnesium 20.6 mg vs. lansoprazole 15 mg at steady state (Day 5).

The primary end point was % of time pH > 4.0 on Day 5.

It should be noted that the tested formulation is lansoprazole 15 mg, which is the same formulation as Prevacid24HR.

Study Results

Patients taking/who took Prilosec OTC experienced 24% longer acid control vs. Prevacid 15 mg (OTC)1 on average.††

72.5% of patients had greater acid control with Prilosec OTC.1††

Prilosec OTC provided some patients up to 2X longer acid control than Prevacid 15 mg (OTC).1††
