Pharmaceutical-grade Sodium Carboxymethyl Starch (CMS-Na) is a highly effective and widely used superdisintegrant in the pharmaceutical industry. Derived from natural starch through chemical modification, this biocompatible and non-toxic excipient boasts excellent water absorption and swelling properties. When incorporated into solid oral dosage forms such as tablets and capsules, CMS-Na rapidly absorbs moisture upon contact with gastrointestinal fluids. This triggers a significant increase in volume, generating strong internal pressures that break the dosage form apart efficiently, thereby accelerating the release of active pharmaceutical ingredients (APIs) and enhancing drug bioavailability.
