Preparation and Characterization of Carbamazepine Cocrystal in Polymer Solution

Pharmaceutics, 2017
In this study, we attempted to prepare carbamazepine (CBZ) cocrystal through the solution method in ethanol-water solvent mixture (volume ratio 1:1) and polyvinyl pyrrolidone (PVP) solution.

Impact of Halogen Substituent Nature and Position on the Structural and Energetic Properties of Carbamazepine Cocrystals with Meta‐Halobenzoic Acids: A Two‐Pathway Synthesis Study

ChemPlusChem, Volume 90, Issue 11, November 10, 2025.
This study explores how halogen substitution in benzoic acid coformers affects the structure and stability of carbamazepine cocrystals. Isostructurality and enhanced lattice stability with heavier halogens are revealed, highlighting key supramolecular interactions.

Formation of Prenylated Chalcone Xanthohumol Cocrystals: Single Crystal X-Ray Diffraction, Vibrational Spectroscopic Study Coupled with Multivariate Analysis

Molecules, 2019
Four novel xanthohumol (XN) cocrystals with pharmaceutically acceptable coformers, such as nicotinamide (NIC), glutarimide (GA), acetamide (AC), and caffeine (CF) in the 1:1 stoichiometry were obtained by the slow evaporation solution growth technique ...

Origin of phase relative stability and phase transformation in an S‐ibuprofen–nicotinamide cocrystal

Acta Crystallographica Section C, Volume 81, Issue 11, Page 658-665, November 2025.
The crystal structure of the metastable form of S‐ibuprofen–nicotinamide cocrystals was solved from powder X‐ray diffraction data and explains the main mechanisms responsible for the relative stability of the two forms of the cocrystals. This also made it possible to explain the transition mechanism between the two forms with temperature.The crystal ...

On the cohomology of elliptic coformal spaces

, 2019
In this article, we pursue the study begun in \cite{Lup02} on the cohomology of rationally elliptic coformal spaces. Consequently, we complete, for such spaces, the proof of Lupton's conjecture and deduce Hilali's.

Solid solution quantification from full powder X‐ray diffraction profile: novel application of multivariate calibration

Journal of Applied Crystallography, Volume 58, Issue 5, Page 1700-1711, October 2025.
A new application of quantitative chemometric models (principal component regression and partial least‐squares regression) to powder X‐ray diffraction data is tested. The approach allows evaluation of the relative composition of solid solutions via the characteristic profile shift.

The curious case of proton migration under pressure in the malonic acid and 4,4′-bipyridine cocrystal

IUCrJ
In the search for new active pharmaceutical ingredients, the precise control of the chemistry of cocrystals becomes essential. One crucial step within this chemistry is proton migration between cocrystal coformers to form a salt, usually anticipated by ...

Design, characterization, and evaluation of an aceclofenac cocrystal for improved solubility and stability

Journal of Applied Pharmaceutical Research
Background: Co-crystallization enhances APIs by forming noncovalent interactions with coformers, thereby improving physicochemical properties. Aceclofenac was selected for its low solubility, whereas L-lysine serves as a coformer to enhance solubility ...

Piroxicam cocrystals with phenolic coformers: preparation, characterization, and dissolution properties

Pharmaceutical Development and Technology, 2018
This study explores the preparation and investigation of dissolution properties of piroxicam cocrystals. Differential scanning calorimetry (DSC) was used to determine the capability of resorcinol (RES), methylparaben (MPB), and vanillin (VAN) to form cocrystals with piroxicam (PRX). Generation of cocrystals was attempted by liquid assisted grinding and
