parenteral dosage form

solutions that are more than skin deep

Bioresorbable polymers have been commercialized for more than 50 years, however, until now, no manufacturer has offered a single source of three key excipients used to formulate these revolutionary drug delivery systems that are designed to improve patients’ lives.

With the addition of Viatel™ bioresorbable polymers, Ashland provides a comprehensive line of products for parenteral, controlled release drug delivery. Complementary excipients include Aqualon™ CMC PH BET sodium carboxymethyl cellulose, a suspending agent for two-component systems; and Pharmasolve™ n-methyl-2-pyrrolidone, a versatile solubilizer for one-component systems.

Parenteral formulations present unique challenges to formulators. Ashland has products that can help address these challenges.

The molecular structure of cyclodextrins creates a bucket-like cavity that can function to complex with molecules or functional groups on molecules. The substitution of hydroxyl groups on native cyclodextrins to make hydroxypropyl-ß- or hydroxypropyl-γ-cyclodextrins (HPBCD or HBGCD) significantly enhances their solubility and makes them more suitable for drug solubilization. This mechanism makes the Cavitron and CAVASOL HPBCDs and HPGCDs capable ...
