Abstract
The present work reviews the liquid antisolvent crystallization (LASC) to prepare the nanoparticle of pharmaceutical compounds to enhance their solubility, dissolution rate, and bioavailability. The application of ultrasound and additives is discussed to prepare the particles with narrow size distribution. The use of ionic liquid as an alternative to conventional organic solvent is presented. Herbal compounds, also known for low aqueous solubility and limited clinical application, have been crystalized by LASC and discussed here. The particle characteristics such as particle size and particle size distribution are interpreted in terms of supersaturation, nucleation, and growth phenomena. To overcome the disadvantage of batch crystallization, the scientific literature on continuous flow reactors is also reviewed. LASC in a microfluidic device is emerging as a promising technique. The different design of the microfluidic device and their application in LASC are discussed. The combination of the LASC technique with traditional techniques such as high-pressure homogenization and spray drying is presented. A comparison of product characteristics prepared by LASC and the supercritical CO2 antisolvent method is discussed to show that LASC is an attractive and inexpensive alternative for nanoparticle preparation. One of the major strengths of this paper is a discussion on less-explored applications of LASC in pharmaceutical research to attract the attention of future researchers.

Dose Escalation Study to Assess the Pharmacokinetic Parameters of a Nano-amorphous Oral Sirolimus Formulation in Healthy Volunteers. Eur J Drug Metab Pharmacokinet 2019; 44:777-785.

Abstract
BACKGROUND AND OBJECTIVES Sirolimus (Rapamune®) exhibits low bioavailability, high variability and moderate food effect following oral administration. This makes therapeutic blood monitoring of sirolimus concentrations necessary for kidney transplant patients. Furthermore, reaching therapeutic blood sirolimus concentrations in renal cancer patients was found to be challenging when the marketed drug was administered alone. A novel, nano-amorphous formulation of the compound was developed and its pharmacokinetic properties were investigated in a dose escalation study in a first-in-human clinical trial. The effect of food at the highest dose on the pharmacokinetic parameters was also assessed. METHODS Each group received one of the escalating doses (0.5-2-10-40 mg) of sirolimus as the novel formulation in the fasted state. Following a 2- to 3-week washout period, the 40-mg group then also received another 40 mg dose in the fed state. Sirolimus whole blood concentrations were determined for up to 48 h. To avoid degradation of sirolimus in the acidic environment in the stomach, 40 mg famotidine was administered 3 h pre-dose in all regimens. The main pharmacokinetic parameters were calculated and data were compared with pharmacokinetic data reported for dose escalation studies for Rapamune®. RESULTS Thirty-two healthy volunteers were divided into 4 cohorts of 8 volunteers. Dose increments resulted in approximately dose-proportional increases of maximal plasma concentrations (Cmax) and area under the concentration-time curve (AUC)0-48 h up to 10 mg, while less than dose-proportional increases were observed when the dose was increased from 10 to 40 mg. Mean AUCinf at the 40 mg dose in the fasted state was 4,300 ± 1,083 ng·h/ml, which is 28% higher than the AUC reported following the administration of 90 (2 × 45) mg Rapamune® and 11% higher than the exposure reported for 25 mg intravenous pro-drug temsirolimus (3,810 ng·h/ml). At the 40 mg dose, food reduced Cmax by 35.5%, but it had no statistically significant effect on AUC. Inter-individual variability of the pharmacokinetic parameters mostly fell in the 20-30% (CV) range showing that sirolimus administered as the nano-amorphous formulation is a low-to-moderate variability drug. CONCLUSION Based on the pharmacokinetic profiles observed, the nano-amorphous formulation could be a better alternative to Rapamune® for the treatment of mammalian target of rapamycin-responsive malignancies. Therapeutically relevant plasma concentrations and exposures can be achieved by a single 40 mg oral dose. Furthermore, the low variability observed might make therapeutic blood monitoring unnecessary for transplant patients taking sirolimus as an immunosuppressant.

Abstract
Nanocrystallization and amorphization have proven to be two effective strategies to improve the bioavailability of water-insoluble drugs. The purpose of our work was to develop a nano-formulated tablet of sirolimus (SRL) for enhanced dissolution. Amorphous SRL nanocomposites were prepared using anti-solvent precipitation via a high-gravity rotating packed bed. Various factors that affect particle size and size distribution, such as excipients, rotating speed, antisolvent/solvent flow rate, were investigated. Structure, stability and in vitro dissolution of the as-prepared SRL were evaluated. Furthermore, the nanoparticulated SRL tablet formula was screened to control drug release. Importantly, SRL tablets exhibit different dissolution profile by adjusting HPMC (hydroxypropyl methyl cellulose) content, which makes them more suitable for various formulation developments.

Abstract
Drug nanocrystals (NCs) appear to be favorable to improving oral bioavailability of poorly water-soluble drugs as evidenced by the great success they have had in the market. However, the pathway and mechanism of drug NCs through epithelial membrane are still unclear. In an attempt to clarify their transport features, paclitaxel nanocrystals (PTX-NCs), and paclitaxel hybrid NCs with lipophilic carbocyanine dyes, were prepared and characterized as the models. The endocytosis, intracellular trafficking, paracellular transport, and transcytosis of PTX-NCs were carefully investigated with Förster resonance energy transfer (FRET) analysis, as well as a colocalization assay, flow cytometry, gene silencing, Western-blot, transepithelial electrical resistance (TEER) study and other approaches on MDCK cells. It was found that rod-like PTX-NCs could transport through the monolayer intact, and the process of endocytosis proved to be time and energy dependent. Endoplasmic reticulum (ER) and Golgi complexes were colocalized with PTX-NCs in cells, so the ER-Golgi complexes/Golgi complexes-basolateral membrane pathway may be involved in the intracellular trafficking and transcytosis of PTX-NCs. It was demonstrated here that cav-1, dynamin, and actin filament modulated the endocytosis process, and Cdc 42 regulated the transcytosis process. In addition, no paracellular transport of PTX-NCs was observed. These findings demonstrated that the rod-like nanocrystals not only enhanced the transcytosis of PTX compared with microparticles of raw drug materials but also changed the pathways of drug delivery. This study certainly provides insight for the oral absorption mechanism of nanocrystals of poorly soluble drugs.

Abstract
Molecular interactions were investigated within four different co-amorphous drug-amino acid systems, namely indomethacin-tryptophan (Ind-Trp), furosemide-tryptophan (Fur-Trp), indomethacin-arginine (Ind-Arg) and furosemide-arginine (Fur-Arg). The co-amorphous systems were prepared by ball milling for 90min at different molar ratios and analyzed by XRPD and DSC. Interactions within the co-amorphous samples were evaluated based on the deviation between the actual glass transition temperature (Tg) and the theoretical Tg calculated by the Gordon-Taylor equation. The strongest interactions were observed in the 50mol% drug (1:1M ratio) mixtures, with the exception of co-amorphous Ind-Arg where the interactions within the 40mol% drug samples appear equally strong. A particularly large deviation between the theoretical and actual Tgs was observed within co-amorphous Ind-Arg and Fur-Arg systems. Further analysis of these co-amorphous systems by (13)C solid-state NMR (ssNMR) and FTIR confirmed that Ind and Fur formed a co-amorphous salt together with Arg. A modified approach of using the Gordon-Taylor equation was applied, using the equimolar co-amorphous mixture as one component, to describe the evolution of the Tgs with varying molar ratio between the drug and the amino acid. The actual Tgs for co-amorphous Ind-Trp, Fur-Trp and Fur-Arg were correctly described by this equation, confirming the assumption that the excess component was amorphous forming a homogeneous single component within the co-amorphous mixture without additional interactions. The modified equation described the Tgs of the co-amorphous Ind-Arg with excess Arg less well indicating possible further interactions; however, the FTIR and ssNMR data did not support the presence of additional intermolecular drug-amino acid interactions.
