Meglumine

Superior Solubilizing Capacity – Derived from sorbitol, meglumine acts as a high-efficiency pharmaceutical counterion. It significantly boosts the solubility of poorly soluble active drug molecules, resolving formulation challenges of hydrophobic pharmaceuticals.

Elevates Drug Bioavailability – Improved molecular solubility facilitates better in-vivo dissolution and absorption, effectively enhancing the bioavailability and overall therapeutic performance of finished pharmaceutical products.

Ideal Ionization Characteristics – Featuring a suitable pKa value of 9.6, this amino sugar exhibits mild and stable ionization behavior. It readily forms stable drug salts, ensuring excellent formula stability and compatibility.

Clinically Proven Excipient – As a widely validated counterion in pharmaceutical manufacturing, it delivers consistent, reliable and repeatable performance for prescription drug formulation development.

Product Description
