More PPIs are becoming available over the counter, so it's important for healthcare
professionals to gather accurate information and know how they compare to the original
OTC 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 Prevacid24HR.
The Study
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.
The Results
Patients experienced 24% longer acid control vs. Prevacid 15 mg (OTC)1
on average.
72.5% of patients had greater control with Prilosec OTC.1
Prilosec OTC provided some patients up to 2X longer acid control than 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.
It's possible with Prilosec OTC. Use as directed for 14 days for treating frequent
heartburn. It should be noted that the tested formulation is lansoprazole 15 mg,
which is the same formulation as Prevacid24HR.
