Abstract
Coamorphous formulation is a useful approach for enhancing the solubility of poorly water-soluble drugs via intermolecular interactions. In this study, a hydrogen-bonding-based coamorphous system was developed to improve drug solubility, but it barely changed the apparent permeability (Papp) of the drug. This study aimed to design a novel coamorphous salt using ionic interactions to improve drug permeability and absorption. Telmisartan (TMS), with an acidic group, was used to form a coamorphous salt with basic amlodipine (AML). Evaluation of the physicochemical properties confirmed the formation of a coamorphous salt via ionic interactions between the amine group of AML and the carboxyl group of TMS at a molar ratio of 1:1. The coamorphous salt of TMS/AML enhanced the partitioning of both drugs into octanol, indicating increased lipophilicity owing to the interaction between TMS and AML. The coamorphous salt dramatically enhanced TMS solubility (99.8 times that of untreated TMS) and decreased AML solubility owing to the interaction between TMS and AML. Although the coamorphous salt showed a decreased Papp in the permeation study in the presence of a thicker unstirred water layer (UWL) without stirring, Papp increased in the presence of a thinner UWL with stirring. The oral absorption of TMS from the coamorphous salt increased by up to 4.1 times compared to that of untreated TMS, whereas that of AML remained unchanged. Although the coamorphous salt with increased lipophilicity has a disadvantage in terms of diffusion through the UWL, the UWL is thin in human/animal bodies owing to the peristaltic action of the digestive tract. Dissociation of the coamorphous salt on the membrane surface could contribute to the partitioning of the neutral form of drugs to the membrane cells compared with untreated drugs. As a result, coamorphous salt formation has the advantage of improving the membrane permeation and oral absorption of TMS, owing to the enhanced solubility and supply of membrane-permeable free TMS on the surface of the membrane.

Abstract
The objective of this study was to investigate thermodynamic and kinetic miscibility for two structurally similar model compounds nifedipine (NIF) and felodipine (FEL) when formulated as amorphous solid dispersions (ASDs) with an amphiphilic polymer Soluplus®. Thermodynamic miscibility was studied via melting point depression approach for the two systems. The Flory Huggins theory was used to calculate the interaction parameter and generate the phase diagrams. It was shown that NIF was more miscible in Soluplus® than FEL. The nature of drug polymer interactions was studied by fourier transform infra-red spectroscopy (FTIR) and solid-state nuclear magnetic resonance spectroscopy (ssNMR). The data from spectroscopic analyses showed that both the drugs interacted with Soluplus® through hydrogen bonding interactions. Furthermore, 13C ssNMR data was used to get quantitative estimate of the extent of hydrogen bonding for ASDs samples. Proton relaxation measurements were carried out on ASDs in order to evaluate phase heterogeneity on two different length scales of mixing. The data suggested that better phase homogeneity in NIF:SOL systems especially for lower Soluplus® content ASDs on smaller domains. This could be explained by understanding the extent of hydrogen bonding interactions for these two systems. This study highlights the need to consider thermodynamic and kinetic mixing, when formulating ASDs with the goal of understanding phase mixing between drug and polymer.

Application of solid-state 13C relaxation time to prediction of the recrystallization inhibition strength of polymers on amorphous felodipine at low polymer loading. Int J Pharm 2020; 581:119300.

Abstract
The potential for inhibiting recrystallization with Eudragit® L (EUD-L), hypromellose acetate succinate (HPMC-AS), and polyvinylpyrrolidone-co-vinylacetate (PVP-VA) on amorphous felodipine (FLD) at low polymer loading was investigated in this study. The physical stabilities of the FLD/polymer amorphous solid dispersions (ASDs) were investigated through storage at 40 °C. The HPMC-AS and PVP-VA strongly inhibited FLD recrystallization, although EUD-L did not effectively inhibit the FLD recrystallization. The rotating frame 1H spin-lattice relaxation time (1H-T1ρ) measurement clarified that EUD-L was not well mixed with FLD in the ASD, which resulted in weak inhibition of recrystallization by EUD-L. In contrast, the HPMC-AS and PVP-VA were well mixed with the FLD in the ASDs. Solid-state 13C spin-lattice relaxation time (13C-T1) measurements at 40 °C showed that the molecular mobility of the FLD was strongly suppressed when mixed with polymer. The reduction in the molecular mobility of FLD was in the following order, starting with the least impact: FLD/EUD-L ASD, FLD/HPMC-AS ASD, and FLD/PVP-VA ASD. FLD mobility at the storage temperature, evaluated by 13C-T1, showed a good correlation with the physical stability of the amorphous FLD. The direct investigation of the molecular mobility of amorphous drugs at the storage temperature by solid-state NMR relaxation time measurement can be a useful tool in selecting the most effective crystallization inhibitor at low polymer loading.

Abstract
Semiempirical and density functional theory (DFT) methods were herein used to study the encapsulation process of 1,4-dihydropyridine (DHP) derivatives into (10,10) armchair carbon nanotube (CNT(10,10)). The encapsulated DHPs do not affect the overall structural and electronic properties of the CNT(10,10). The following binding energy was obtained from DFT-D3 calculations: DHP_Cl2@CNT(10,10) (–62.36 kcal mol–1) < DHP_Ph@CNT(10,10) (–54.71 kcal mol–1) < DHP_OH@CNT(10,10) (–43.92 kcal mol–1) < DHP_NO2@CNT(10,10) (–41.71 kcal mol–1) < DHP_H@CNT(10,10) (–32.74 kcal mol–1). The increase in the dipole moment for all DHPs@CNT(10,10) indicates their partial solubility in water. Our results play a promising role as a guide for future experiments using CNTs as a vehicle to transport DHP derivatives.
