Pharmaceutical-Grade Pregabalin SR Pellets for Sustained-Release Oral Formulations
Pregabalin SR Pellets are multiparticulate pharmaceutical formulations designed for sustained-release oral dosage applications. Pregabalin is identified by CAS Number 148553-50-8, molecular formula C₈H₁₇NO₂, and molecular weight 159.23 g/mol. PubChem identifies Pregabalin as the S-enantiomer of 3-(aminomethyl)-5-methylhexanoic acid.
The SDP pellet product portfolio lists Pregabalin SR Pellets in 25%, 50% and 75% strengths, providing multiple active-loading options for pharmaceutical formulation development.
The sustained-release pellet format provides a multiparticulate platform designed to modify the release profile of Pregabalin. Such pellets can be incorporated into suitable oral dosage forms, including capsule-filling applications. Final release characteristics depend on the formulation composition, active loading, coating system, pellet characteristics and applicable finished-product specification.
Pregabalin has the molecular formula C₈H₁₇NO₂, molecular weight 159.23 g/mol, and CAS Number 148553-50-8. It is a chiral molecule and the pharmaceutical active material corresponds to the S-enantiomer.
For the finished Pregabalin SR Pellets, the 25%, 50% and 75% values represent active ingredient loading and should not be confused with the purity assay of the Pregabalin raw material.
These three strengths are listed for Pregabalin SR Pellets in the referenced pharmaceutical pellet product portfolio.
