Abstract :

A variety of Active Pharmaceutical Ingredients (API��?s) can exist as hydrate forms. The conditions that facilitate hydrate formation include factors such as humidity exposure during storage, pharmaceutical processing and dosage forms capable of transferring water to API. It is mainly the thermodynamic water activity of the surrounding medium (solution, vapour phase, etc.) that determines whether a given hydrate structure can be formed. Studies that evaluate hydrate structure and stability will be beneficial to the understanding of hydrate formation and influence on physico-chemical properties. Thermal analysis has been widely used for characterization of pharmaceutical hydrates in terms of structural and stability investigations. For hydrate compounds the use of Thermo-Gravimetric (TG) analysis had explored both isothermal and non-isothermal heating regimes for the investigation of thermally stimulated dehydration kinetic parameters. Knowledge of dehydration kinetic parameters under a controlled heating program offer unique insight to drug-water association as the kinetic information mostly relate to structural features and intermolecular forces operating with the parent anhydrate drug form. This study report findings of dehydration kinetic parameters from two structurally relates macrolide antibiotics in an attempt to correlate observed kinetic behaviour to the structural characterization of the hydrate compounds.
