Sodium 8-(2-Hydroxybenzoyl) Amino Octanoate
Sodium 8-(2-Hydroxybenzoyl) Amino Octanoate, commonly known as SNAC, is a groundbreaking pharmaceutical excipient that acts as a chemical permeation enhancer. Its primary function is to significantly improve the oral absorption of macromolecules, peptides, and proteins which typically exhibit poor bioavailability when administered orally. This advanced capability makes SNAC instrumental in developing effective oral formulations for a range of challenging therapeutic agents.
- Facilitating oral peptide drug delivery systems: SNAC is pivotal in enabling the oral administration of peptides, a class of drugs that have historically been limited to injectable routes due to poor gastrointestinal absorption.
- Enhancing oral bioavailability of macromolecules: By increasing the permeability across biological membranes, SNAC ensures that a higher concentration of the administered drug reaches the bloodstream, thereby improving its therapeutic efficacy.
- GRAS status by FDA for enhanced safety: Recognized as Generally Regarded As Safe (GRAS) by the U.S. Food and Drug Administration, SNAC offers a robust safety profile, making it a preferred choice in pharmaceutical formulations for human consumption.
- Key role in oral insulin and heparin delivery: SNAC's ability to promote absorption has been extensively studied for oral formulations of drugs like insulin (for diabetes management) and heparin (for cardiovascular conditions), offering non-invasive alternatives.
Advantages Provided by the Product
Improved Oral Bioavailability
SNAC's primary advantage is its ability to significantly boost the oral bioavailability of poorly absorbed drugs, transforming challenging oral drug delivery systems into viable therapeutic options. This contributes to better patient outcomes.
Expanded Therapeutic Options
By enabling oral administration of peptides and proteins, SNAC unlocks new therapeutic possibilities for diseases that previously required injections, enhancing patient convenience and adherence.
Enhanced Drug Stability and Solubility
The surfactant properties of SNAC help in the uniform dispersion of drug molecules in solutions, which can lead to increased drug stability and overall bioavailability, further optimizing pharmaceutical formulations.
Key Applications
Oral Peptide Drug Delivery
SNAC is vital for the oral delivery of peptide-based drugs, enhancing their journey through the gastrointestinal tract to reach systemic circulation effectively.
Macromolecule Absorption Enhancement
It serves as a critical agent for increasing the absorption of large molecule drugs, expanding treatment options for various medical conditions.
Pharmaceutical Formulation Development
SNAC is a key excipient for formulators aiming to create effective and convenient oral dosage forms for biopharmaceuticals.
Treatment of GI Diseases
Its application extends to treating gastrointestinal diseases where enhanced drug absorption is crucial for therapeutic success.
