Nutraceutical cocrystals: utilizing pterostilbene as a cocrystal former
CrystEngComm, 2010The nutraceutical compound pterostilbene is investigated for its propensity to form cocrystalline materials with active pharmaceutical ingredients. Three cocrystals of a 1 : 1 stoichiometric molar ratio of pterostilbene with caffeine (two polymorphs, Form I and Form II) and carbamazepine were prepared and characterized by crystallographic (XRPD, single-

Cocrystal Formation between Chiral Compounds: How Cocrystals Differ from Salts
Crystal Growth & Design, 2014A cocrystal screening of a series of chiral target compounds was performed in order to investigate the propensity for two optically active compounds to cocrystallize in an enantiospecific manner. Thirteen novel cocrystal systems were identified, out of which 11 are enantiospecific and two present a diastereomeric cocrystal pair, yielding a total of 15 ...

Stability screening of pharmaceutical cocrystals
Pharmaceutical Development and Technology, 2021An efficient protocol for assessing both the chemical and physical stability of cocrystalline forms of active pharmaceutical ingredients (APIs) is proposed. In this protocol, the cocrystalline material is used to prepare two standard formulations, mimicking wet granulations, to make low-dose tablets.

Celecoxib–Nicotinamide Cocrystal Revisited: Can Entropy Control Cocrystal Formation?
Crystal Growth & Design, 2017The cocrystal of celecoxib–nicotinamide has been revisited to reveal its crystal structure and unusual formation properties. Gibbs free energy and enthalpy of formation at 25 °C were determined by solubility and thermal analysis. The formation of celecoxib–nicotinamide was found to be an endothermic process and driven by entropy, a mechanism different ...
