Abstract
Evolving therapeutic landscape through combinatorial chemistry and high throughput screening have resulted in an increased number of poorly soluble drugs. Drug delivery strategies quickly adapted to convert these drugs into successful therapies. Amorphous solid dispersion (ASD) technology is widely employed as a drug delivery strategy by pharmaceutical industries to overcome the challenges associated with these poorly soluble drugs. The development of ASD formulation requires an understanding of polymers and manufacturing techniques. A review of US FDA-approved ASD-based products revealed that only a limited number of polymers and manufacturing technologies are employed by pharmaceutical industries. This review provides a comprehensive guide for the selection and overview of polymers and manufacturing technologies adopted by pharmaceutical industries for ASD formulation. The various employed polymers with their underlying mechanisms for solution-state and solid-state stability are discussed. ASD manufacturing techniques, primarily implemented by pharmaceutical industries for commercialization, are presented in Quality by Design (QbD) format. An overview of novel excipients and progress in manufacturing technologies are also discussed. This review provides insights to the researchers on the industrially accepted polymers and manufacturing technology for ASD formulation that has translated these challenging drugs into successful therapies.

Int J Parasitol Drugs Drug Resist 2022; 20:113-120. [PMID: 36375338 PMCID: PMC9771833 DOI: 10.1016/j.ijpddr.2022.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 10/24/2022] [Accepted: 10/25/2022] [Indexed: 11/11/2022]
Abstract
Malaria is among the most devastating and widespread tropical parasitic diseases in developing countries. To prevent a potential public health emergency, there is an urgent need for new antimalarial drugs, with single-dose cures, broad therapeutic potential, and novel mechanism of action. We synthesized HCl salt of SKM13 (SKM13-2HCl) based on the modification of SKM13 to improve solubility in water. The anti-malarial activity of the synthesized drug was evaluated in both in vitro and in vivo models. The selective index indicated that SKM13-2HCl showed the same effectiveness with SKM13 in Plasmodium falciparum in in-vitro. Even though, in vivo mouse study demonstrated that SKM13 (20 mg/kg) at single dose could not completely inhibit P. berghei growth in blood. The survival rate increased from 33 to 90% at 15 days after infection. However, SKM13-2HCl (20 mg/kg) at a single dose increased the survival rate up to 100% at the same duration. Ultra-High-Performance Liquid Chromatography (UHPLC) showed that solubility in water of SKM13 and SKM13-2HCL was 0.389 mg/mL and 417 mg/mL, respectively. Pharmacokinetics (PK) analysis corresponded to the increased solubility of SKM13-2HCl over SKM13. Haematological parameters [red blood cell (RBC) count, haemoglobin level, and haematocrit level] supported the comparable efficacy of SKM13 and SKM13-2HCl in a 4-day suppression test. One mode of these drugs was found to be activating phosphorylation of eIF2α, hallmark of ER-stress, to kill parasite. Novel salt derivative of SKM13 (SKM13-2HCl) have enhanced anti-malarial activity against P. falciparum with endoplasmic reticulum (ER)-stress and salt form of SKM13 is an excellent direction to develop anti-malarial drug candidate in mice model.

Electrospun Nanofibers of Polycaprolactone/Collagen as a Sustained-Release Drug Delivery System for Artemisinin. Pharmaceutics 2021; 13:pharmaceutics13081228. [PMID: 34452189 PMCID: PMC8402154 DOI: 10.3390/pharmaceutics13081228] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 08/04/2021] [Accepted: 08/05/2021] [Indexed: 11/23/2022] Open
Abstract
The application of artemisinin (ART) in the treatment of malaria has been restricted to a certain degree due to its inherent limitations, such as short half-life, poor solubility, limited bioavailability, and re-crystallization. Electrospun nanofibers loaded with ART provide an excellent solution to these limitations and yield sustained drug release as well as inhibition of drug re-crystallization. In this study, ART-loaded polycaprolactone (PCL)/collagen (Col) nanofibers with different proportions of polymers were prepared. ART-loaded PCL/Col nanofibers were characterized, and further ART anti-crystallization and release behaviors were studied. SEM was used to observe the morphology of PCL/Col nanofibers. X-ray diffraction (XRD) was used to characterize the physical state of ART in ART-loaded PCL/Col nanofibers. Fourier transform infrared spectroscopy (FTIR), water contact angle measurement, weight loss, degree of swelling, and drug release experiments can verify the differences in performance of ART-loaded PCL/Col nanofibers due to different polymer ratios. The release curve was analyzed by kinetics, showing sustained release for up to 48 h, and followed the Fickian release mechanism, which was shown by the diffusion index value obtained from the Korsmeyer-Peppas equation.

Ternary Phase Diagram Development and Production of Niclosamide-Urea Co-Crystal by Spray Drying. J Pharm Sci 2020; 110:2063-2073. [PMID: 33285181 DOI: 10.1016/j.xphs.2020.11.036] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Revised: 11/10/2020] [Accepted: 11/30/2020] [Indexed: 12/18/2022]
Abstract
In this work, a ternary phase diagram was developed for a Niclosamide-urea co-crystal (NCS-UR) in isopropanol (IPA) using a combination of slurry and solvent addition methods. The ternary phase diagram showed that solubility of Niclosamide and urea differed by an order of magnitude in IPA, leading to an incongruently saturating system. Spray drying was explored as a method to generate NCS-UR. Co-crystals with small, uniform particle size were successfully prepared by spray drying from equimolar solutions with yield up to 73%. Co-crystals were phase pure by X-ray powder diffraction (XRPD) and differential scanning calorimetry (DSC) from all conditions explored. Somewhat similar particles were obtained at inlet temperature of 70 °C (mean size of 2.0 μm) compared to 85 °C (2.8-3.4 μm). Based on the TPD, isolating phase pure co-crystal through solution crystallization in IPA would require excess urea. However, spray drying did not require excess co-former. The in-vitro solubility of NCS-UR was compared to anhydrous NCS in biorelevant media. NCS-UR did not give improvement in solubility at 1 h or 24 h. Overall, this work showed that spray drying is a feasible process for preparing phase pure co-crystals for an incongruently saturating system and simultaneously generating micron size particles.

Enhancement of transdermal delivery of artemisinin using microemulsion vehicle based on ionic liquid and lidocaine ibuprofen. Colloids Surf B Biointerfaces 2020; 189:110886. [PMID: 32109824 DOI: 10.1016/j.colsurfb.2020.110886] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 02/17/2020] [Accepted: 02/18/2020] [Indexed: 12/18/2022]
Abstract
A microemulsion system based on ionic liquid (IL) and deep eutectic compound was proposed to improve the transdermal delivery of artemisinin. Deep eutectic lidocaine ibuprofen (Lid·Ibu) was selected as the oil phase, and the imidazolium ionic liquid, 1-hydroxyethyl-3-methylimidazolium chloride ([HOEmim]Cl), was incorporated into the aqueous phase as a transdermal enhancer. The ingredients for the microemulsion in this study were selected, and their ratios were optimized. The optimal microemulsion carrier was composed of 45 wt% of water phase, 45 wt% surfactant phase (containing Tween-80, Span-20, and ethanol (co-surfactant) with the weight ratio of 1:1:1), and 10 wt% Lid·Ibu as the oil phase with artemisinin loading of 1.0 wt% (all the ratios were based on the total weight of microemulsion). Physical properties of this microemulsion, including particle size (41.95 ± 0.85 nm), viscosity (26.65 ± 0.13 mPa·s) and density (1.02 g/cm3), were measured. In-vitro transdermal assay showed a remarkable enhancement of artemisinin transport through the skin, with the permeation flux being 3-fold of the value for isopropyl myristate system in 6 h. The impact of IL-based microemulsion (ILME) on stratum corneum (SC) was investigated by DSC, ATR-FTIR and AFM, which unveiled that the ILME possesses the ability of reducing the SC barrier by disrupting the regular arrangement of keratin, resulting in enhancement of transdermal delivery of artemisinin. This current work suggested that the microemulsion proposed here had an excellent capability to promote the transdermal delivery of artemisinin, which might also be a promising vehicle for the skin delivery of other hydrophobic natural drugs.

Abstract
The objective of this study is to enhance the dissolution rate, supersaturation and physicochemical stability of combination of two poorly water-soluble anti-malarial drugs, artemisinin (ART) and mefloquine (MFQ), by encapsulating them inside mesoporous silica (SBA-15) via co-spray drying. Characteristic studies such as powder X-ray diffraction (PXRD), transmission electron microscopy (TEM) and scanning electron microscope (SEM) clearly indicate the amorphization of the crystalline drugs. ART/MQF/SBA-15 formulations show a superior dissolution enhancement with a burst release of more than 95% of drugs within 30min. In addition, the combination formulation exhibits a stable supersaturation enhancement by 2-fold higher than that of the untreated crystalline counterparts. ART/MQF/SBA-15 samples possess excellent physicochemical stability under 2 different moderate storage conditions for 6 months. The amorphization of ART and MFQ via nano-confinement using mesoporous SBA-15 is a potentially promising approach to enhance the solubility of poorly water-soluble anti-malarial drugs that co-formulated into a single dosage form.

Abstract
Spray drying is a well-established manufacturing technique which can be used to formulate amorphous solid dispersions (ASDs) which is an effective strategy to deliver poorly water soluble drugs (PWSDs). However, the inherently complex nature of the spray drying process coupled with specific characteristics of ASDs makes it an interesting area to explore. Numerous diverse factors interact in an inter-dependent manner to determine the final product properties. This review discusses the basic background of ASDs, various formulation and process variables influencing the critical quality attributes (CQAs) of the ASDs and aspects of downstream processing. Also various aspects of spray drying such as instrumentation, thermodynamics, drying kinetics, particle formation process and scale-up challenges are included. Recent advances in the spray-based drying techniques are mentioned along with some future avenues where major research thrust is needed.

Abstract
Solid dispersions of the poorly soluble drug artemisinin were developed using polymer blends of polyvinylpyrrolidone (PVP) and polyethylene glycol (PEG) with the aim of enhancing solubility and in vitro permeation of artemisinin through skin. Formulations were characterised using a combination of molecular dynamics (MD) simulations, differential scanning calorimetry (DSC), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Solubility of artemisinin was determined in two solvents: de-ionised water and phosphate buffered saline (PBS; pH 7.4), while in vitro drug permeation studies were carried out using rabbit skin as a model membrane. MD simulations revealed miscibility between the drug and polymers. DSC confirmed the molecular dispersion of the drug in the polymer blend. Decrease in crystallinity of artemisinin with respect to polymer content and the absence of specific drug-polymer interactions were confirmed using XRD and FT-IR, respectively. The solubility of artemisinin was dramatically enhanced for the solid dispersions, as was the permeation of artemisinin from saturated solid-dispersion vehicles relative to that from saturated solutions of the pure drug. The study suggests that high energy solid forms of artemisinin could possibly enable transdermal delivery of artemisinin.

Abstract
Artemisinin, a poorly water-soluble antimalarial drug, presents a low and erratic bioavailability upon oral administration. The aim of this work was to study an agglomerated powder dosage form for oral administration of artemisinin based on the artemisinin/β-cyclodextrin primary microparticles. These primary microparticles were prepared by spray-drying a water-methanol solution of artemisinin/β-cyclodextrin. β-Cyclodextrin in spray-dried microparticles increased artemisinin water apparent solubility approximately sixfold. The thermal analysis evidenced a reduction in the enthalpy value associated with drug melting, due to the decrease in drug crystallinity. The latter was also evidenced by powder X-ray diffraction analysis, while (13)C-NMR analysis indicated the partial complexation with β-cyclodextrin. Agglomerates obtained by sieve vibration of spray-dried artemisinin/β-cyclodextrin primary microparticles exhibited free flowing and close packing properties compared with the non-flowing microparticulate powder. The in vitro dissolution rate determination of artemisinin from the agglomerates showed that in 10 min about 70% of drug was released from the agglomerates, whereas less than 10% of artemisinin was dissolved from raw material powder. Oral administration of agglomerates in rats yielded higher artemisinin plasma levels compared to those of pure drug. In the case of the agglomerated powder, a 3.2-fold increase in drug fraction absorbed was obtained.
