Built-in buffer protects omeprazole, allowing for immediate release1
- At pH 1.2 (normal stomach pH), omeprazole degradation half-life is 2.8 minutes3
- At pH 7.0 (neutral pH), omeprazole degradation half-life is 39 hours3
ZEGERID contains a buffer that raises gastric pH and protects omeprazole from acid degradation4
- Achieves peak plasma levels in ~30 minutes
- Provides continued acid control
The correlation of pharmacodynamic data to clinical effect has not been established.
