Pharmaceutical cocrystallization techniques. Advances and …

LAG can avoid problems related to cocrystal compounds solubility, which are a large barrier in the use of solution-based methods. One example of that is the theobromine-malonic acid system, from which cocrystal formation appear to be impossible due to the low solubility and precipitation of theobromine (Karki et al., 2007). However, through ...

Organic Cocrystals: New Strategy for Molecular …

Recently, cocrystal engineering—a novel strategy for designing multifunctional organic materials—has attracted increasing attention. In contrast to inorganic materials, organic materials show significant advantages in terms of, for example, large-scale fabrication, low cost, and flexibility [1–4].Moreover, compared to polymers, the crystallinity of small molecules tends …

Pharmaceutical cocrystals: An overview - ScienceDirect

Based on this definition of cocrystals, a pharmaceutical cocrystal means a cocrystal with one of the cocrystal components as an Active Pharmaceutical Ingredient (API) and the other components are called coformers. From the definition, it is clearly shown that an API hydrate is not a cocrystal, however a solid-state API hydrate can cocrystallise ...

Nucleation of the Theophylline:Salicylic Acid 1:1 Cocrystal

The cocrystal mole fraction solubility is calculated from the g/g measurement as the moles of the cocrystal 1:1 assembly (defined as 1 mole of THP and 1 mole of SA) per the total moles of the cocrystal 1:1 assembly and solvent. The solubility product of the cocrystal at 10.0 °C is 8.8867 × 10 –7 (mol/mol) 2. THP II exhibits a lower mole ...

Polymorphs, Salts, and Cocrystals: What's in a Name?

A cocrystal contg. the API and glutaric acid in a 1:1 mol. ratio was identified and the single crystal structure is reported. Phys. characterization of the cocrystal showed that it is unique regarding thermal, spectroscopic, x-ray, and dissoln. properties. The cocrystal solid is nonhygroscopic, and chem. and phys. stable to thermal stress.

Pharmaceutical cocrystals: A review of preparations, …

Pharmaceutical cocrystals are defined as crystals that comprise two or more discrete neutral molecules at a stoichiometric ratio and bond together via noncovalent bond interactions (e.g., hydrogen bonding, van der Waals and π···π stacking interactions), in which at least one of the components is API and the others are pharmaceutically acceptable ingredients 17.

Creating Cocrystals: A Review of Pharmaceutical Cocrystal …

Originally discovered almost a century ago, cocrystals continue to gain interest in the modern day due to their ability to modify the physical properties of solid-state materials, particularly pharmaceuticals. Intensification of cocrystal research efforts has been accompanied by an expansion of the potential applications where cocrystals can offer a benefit. Where once …

Cocrystallization of an Antiretroviral Drug Nevirapine: An …

Nevirapine (NEV) is an antiretroviral drug which falls under the Biopharmaceutics Classification System (BCS) class II category. In this work, we report the synthesis of new eutectic and cocrystal of NEV with enhanced dissolution. NEV resulted into an eutectic with paracetamol (PAR) at a NEV mole fraction (XNEV) of 0.25 (corresponding to a NEV-PAR stoichiometric …
