PolyBlend Rx™ Suppository Base
PolyBlend Rx™ is an anhydrous granular form pharmaceutical base for use in the preparation of suppositories when a water-soluble or water-miscible base is preferred. Consists of varying molecular weight polyethylene glycols, a suspending agent, and functional emulsifiers that help with dispersibility and bioavailability of hydrophobic actives. Due to the specific polyethylene glycols used in this proprietary blend, it exhibits excellent stability at room temperature. Melting point: 50.0 to 60.0°C (122 to 140°F). Releases active pharmaceutical ingredients by dissolving rather than melting, providing an extended disintegration time. Recommended for vaginal and rectal suppositories with a long history of use in pharmaceutical applications worldwide. Exhibits excellent mold release characteristics -mold lubrication is not required. Ingredients meet the requirements of USP-NF.
