Abstract
Posaconazole is a broad-spectrum antifungal agent exhibiting rich polymorphism. Up to now, a total of fourteen different crystal forms have been reported, sometimes with an ambiguous nomenclature, but less is known about their properties and stability relationships. Investigating the solid-state of a drug compound is essential to identify the most stable form under working conditions and to prevent the risk of undesired solid-phase transformations under processing and storage. In this paper, we study posaconazole polymorphism by providing a description of its polymorphs, hydrates, and solvates. Powder X-ray diffraction (PXRD), dynamic vapor sorption (DVS), spectroscopic and thermal techniques were employed to characterize the different forms. In addition, the solid-phase transformations of posaconazole in aqueous suspensions were studied by means of Raman microscopy. Surprisingly, we found that Form S, the crystal form contained in the marketed oral suspension, is not the most stable form in water. Form S readily converts to a more stable hydrate, i.e. Form A, after storage in water for two weeks. In the commercial oral formulation the conversion between the two forms is prevented by the presence of polysorbate 80. Such insights into the stabilizing excipient effects beyond particle dispersion are critical to formulators.

Abstract
Hypothesis Additives like Tetrahydrofuran (THF) and Sodium Dodecylsulfate (SDS) improve Carbon Dioxide (CO2) hydrates thermal stability and growth rate when used separately. It has been hypothesised that combining them could improve the kinetics of growth and the thermodynamic stability of CO2 hydrates. Simulations and Experiments We exploit atomistic molecular dynamics simulations to investigate the combined impact of THF and SDS under different temperatures and concentrations. The simulation insights are verified experimentally using pendant drop tensiometry conducted at ambient pressures and high-pressure differential scanning calorimetry. Findings Our simulations revealed that the combination of both additives is synergistic at low temperatures but antagonistic at temperatures above 274.1 K due to the aggregation of SDS molecules induced by THF molecules. These aggregates effectively remove THF and CO2 from the hydrate-liquid interface, thereby reducing the driving force for hydrates growth. Experiments revealed that the critical micelle concentration of SDS in water decreases by 20% upon the addition of THF. Further experiments in the presence of THF showed that only small amounts of SDS are sufficient to increase the CO2 storage efficiency by over 40% compared to results obtained without promoters. Overall, our results provide microscopic insights into the mechanisms of THF and SDS promoters on CO2 hydrates, useful for determining the optimal conditions for hydrate growth.

Abstract
Amorphisation within the final dosage form, i.e. in situ amorphisation, seeks to circumvent the potential stability issues associated with poorly soluble drugs in amorphous solid dispersions (ASDs). Microwave irradiation has previously been shown to enable in situ preparation of ASDs, when a high amount of microwave absorbing water was introduced into the final dosage form by conditioning at high relative humidity. In this study, an alternative to this conditioning step was investigated by introducing crystal water in form of sodium dihydrogen phosphate (NaH2PO4) di-, and monohydrate, in compacts prepared with 30 % w/w celecoxib (CCX) in polyvinylpyrrolidone K12 (PVP). As controls, compacts prepared with NaH2PO4 anhydrate and without NaH2PO4 were included in the study. The quantification of amorphous CCX after microwave irradiation showed an increase in CCX amorphicity for compacts containing NaH2PO4 di-, and monohydrate with increasing irradiation time. Complete amorphisation of CCX in compacts containing NaH2PO4 di-, and monohydrate was observed after 6 min, while no appreciable amorphisation was observed for the control compacts containing NaH2PO4 anhydrate and without NaH2PO4. Modulated differential scanning calorimetric analysis revealed that a homogenous ASD was formed after 12 min and 6 min for compacts containing NaH2PO4 di-, and monohydrate, respectively. Thermal gravimetric analysis indicated that NaH2PO4 monohydrate showed higher dehydration rates compared to the dihydrate, which in turn resulted in higher compact temperatures, and overall increased the rate of amorphisation and reduced the microwave irradiation time necessary to achieve a homogenous ASD. The present results confirmed the suitability of NaH2PO4 di- and monohydrate as alternative sources of water, the primary microwave absorbing material, for in situ microwave amorphisation. The use of crystalline hydrates as water reservoirs for in situ amorphisation circumvents the time-consuming and highly impractical conditioning step previously reported in order to achieve complete amorphisation. Additionally, it allows for easier and more accurate adjustment of the compacts water content, which directly affects the temperature reached during microwave irradiation, and thus, the rate of amorphisation.

Abstract
In ocean conditions of low temperature and high pressure, gas can be converted into hydrates, impacting the behavior of plumes from oil and gas blowouts. This study presented and evaluated formulations to parameterize the processes of formation, dissolution, and decomposition of hydrates implemented in a numerical model that simulates the fate of oil and gas releases in deepwater. Comparisons between the model results and available observations showed a good agreement. Numerical experiments were performed to understand the plume behavior with the presence of hydrates from blowouts at different depths. The analysis of the dynamics of the plume composed of water and gas showed that the hydrate formation increases the plume density and reduces its acceleration due to the buoyancy. As expected, the deeper the blowout, the greater the mass of hydrate in the plume and slower its displacement, spending more time to complete the disappearance of the hydrate.

Abstract
We aimed to evaluate the effect of crystalline forms of aripiprazole, an antipsychotic drug for schizophrenia, on the dissolution rates and oral pharmacokinetics. Solubility, intrinsic dissolution rates, and tablet dissolution rates of the monohydrate (MA) and the anhydrous form (AA) were measured in various aqueous media while monitoring the phase transformation by ATR-FTIR. And their oral pharmacokinetics in dogs were compared. The intrinsic dissolution rate of MA was lower compared to AA, confirming its thermodynamic stability relative to AA in water. Phase transformations during the solubility measurement were media-dependent: In simulated gastric fluid, both AA and MA changed to HCl salt form, whereas AA and HCl salt form transformed to MA in simulated intestinal fluid. In vitro dissolution rates and dog oral pharmacokinetics of AA and MA tablets were similar. The results suggest that the solution-mediated transformation to HCl salt or MA negates the effect of different crystalline forms on dissolution rates in vivo and, consequently, on oral pharmacokinetics. We emphasize the importance of the dissolution tests employing various bio-relevant media for better prediction of in vivo performance and the selection of a solid form for development.

Abstract
We previously reported a humidity-mediated method to effectively remove methanol from the crystal lattice of 3',5'-cyclic monophosphate sodium (cAMPNa) methanol trihydrate, converting it to the pentahydrate without changing its inherent orthorhombic packing mode, and preserving its stability. In this paper, we expand this approach to the removal of residual solvents from l-lysine l-glutamate salt and inosine-5'-monophosphate, and contrast the humidity-mediated method with a solvent-mediated method and a conventional drying method. The packing density of the products obtained from the humidity-mediated method were ∼60% higher than those of the products obtained from the solvent-mediated method, and their stability is ∼5-10% higher than those obtained from the solvent-mediated and traditional drying methods. Furthermore, the humidity-mediated method can remove residual methanol more completely. Therefore, the humidity-mediated method can be regarded as a simple and effective route to eliminate residual solvent from crystal lattice for some crystal products, especially residual methanol.

Abstract
Water plays a complex and central role in determining the structural and reactive properties in numerous chemical systems. In crystalline materials with structural water, the primary focus is often to relate hydrogen bonding motifs to functional properties such as solubility, which is highly relevant in pharmaceutical applications. Nevertheless, understanding the full electrostatic landscape is necessary for a complete structure-function picture. Herein, a combination of tools including 1H magic angle spinning NMR and X-ray crystallography are employed to evaluate the local landscape of water in crystalline hydrates. Two hydrates of an anti-leukemia drug mercaptopurine, which exhibit dramatically different dehydration temperatures (by 90°C) and a three-fold difference in the in vivo bioavailability, are compared. The results identify an electrosteric caging mechanism for a kinetically trapped water in the hemihydrate form, which is responsible for the dramatic differences in properties.

Abstract
Active pharmaceutical ingredients (APIs) may exist in various solid forms, which can lead to differences in the intermolecular interactions, affecting the internal energy and enthalpy, and the degree of disorder, affecting the entropy. Differences in solid forms often lead to differences in thermodynamic parameters and physicochemical properties for example solubility, dissolution rate, stability and mechanical properties of APIs and excipients. Hence, solid forms of APIs play a vital role in drug discovery and development in the context of optimization of bioavailability, filing intellectual property rights and developing suitable manufacturing methods. In this review, the fundamental characteristics and trends observed for pharmaceutical hydrates, solvates and amorphous forms are presented, with special emphasis, due to their relative abundance, on pharmaceutical hydrates with single and two-component (i.e. cocrystal) host molecules.

Abstract
Abstract The International Union of Pure and Applied Chemistry (IUPAC) project of collection, compilation, and critical evaluation of solubility data of bromides and iodides of the scandium group and all lanthanides in water and aqueous systems containing either halide acids, halide salts, or organic compounds is under preparation. As a result of their similarity to the chlorides, which were recently evaluated, the bromides and iodides in the lanthanide series should show some regularities in their solubility data. Unfortunately, the corresponding results show a large scatter when ordered according to the atomic number. Thus, it is complicated to select the best data for recommendation. Reasons for the inaccuracy of solubility measurements are outlined. In fact some solubility values of bromides predicted by correlation with chlorides seem to be more reliable than the experimental ones. As sufficient experimental data at various temperatures were available, the water-rich fragment of the LaBr3–H2O equilibrium phase diagram has been formed and depicted. It seems to be similar to the well-known LaCl3–H2O diagram. Several regularities, with respect to stoichiometry and solubility of compounds formed, were observed during investigations of the aqueous ternary systems. The complex iodides of various lanthanides display more regularities in their properties than the bromides do. Graphical abstract ![]()
