Reduce the cost and time associated with drug product development by determining and selecting an optimal solid form for performance, processability, stability and manufacturability with ÌìÃÀ´«Ã½’s expertly designed solid-state characterization studies, delivered by dedicated teams of pharmaceutical scientists with extensive advanced chemical synthesis knowledge.

A phase-appropriate solid-state analysis strategy early on in development, purposefully designed to accelerate timelines, will ensure that all viable options are considered, and an optimal lead solid form is selected. Our complete suite of solid-state chemistry services can be easily incorporated into both drug substance and drug product development programs. Consistent drug product manufacturing, formulation viability and patent protection require a comprehensive understanding of the solid-state characteristics and behavior of active pharmaceutical ingredients (APIs) and excipients, which may exist in a variety of solid forms, including salts, solvates, hydrates, co-crystals and polymorphs.

Selecting the best available solid state candidate is a critical aspect of pharmaceutical development, as different forms or crystal structures (polymorphism) can exhibit distinct functional properties and behaviors, impacting physical and chemical stability, solubility, bioavailability, reactivity, and more. Drug polymorph screening techniques are remarkably effective at identifying and characterizing solid-state forms of substances, facilitating the development of methods to ensure the quality and consistency of solid-state materials used throughout development, formulation and clinical manufacturing.
