What Are Key Excipient Requirements for Acid Reducers?
Acid reducers, such as proton pump inhibitors (PPIs) and H2 receptor antagonists, demand excipients with specific attributes:
- pH Stability: Excipients must withstand acidic conditions within the gastrointestinal (GI) tract.
- Compatibility: Compatibility with active pharmaceutical ingredients (APIs), such as omeprazole or ranitidine.
- Controlled Release: Ability to facilitate timed or sustained drug release to optimize therapeutic effects.
- Bioavailability Enhancement: Some excipients improve absorption and bioavailability, critical for weakly soluble drugs.
- Protection of API: Excipients may protect acid-labile APIs from premature degradation.
Common excipients include coatings like hydroxypropyl methylcellulose (HPMC), ethyl cellulose, and enteric polymers.
