Hot Melt Extrusion for Improving the Physicochemical Properties of Polydatin Derived from Polygoni cuspidati Extract; A Solution Recommended for Buccal Applications. Pharmaceuticals (Basel) 2023; 16:1226. [PMID: 37765035 PMCID: PMC10535885 DOI: 10.3390/ph16091226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 08/22/2023] [Accepted: 08/29/2023] [Indexed: 09/29/2023] Open
Abstract
Three different types of solid dispersions based on polyvinyl polymers and related copolymers (Kollidon® VA64, Soluplus® and Kollicoat IR®) comprising polydatin-rich Polygoni cuspidati extract were prepared by hot melt extrusion. The systems were characterized using X-ray powder diffraction, infrared spectroscopy as well as by polydatin release and in vitro permeability. Mucoadhesive tablets were prepared from the extrudates based on Kollidon® VA64 and Soluplus® to obtain a suitable pharmaceutical form, where (hydroxypropyl)methyl cellulose was added as a mucoadhesive agent. The tablets were evaluated in terms of the kinetics of polydatin release as well as their mucoadhesive properties. The best tabletability properties, polydatin release profile and adequate mucoadhesive properties were obtained by the formulation containing the Kollidon® VA64-based extrudate, which makes it an excellent prototype for enhancing the release of poorly water-soluble compounds.

Abstract
Internal lubrication with magnesium stearate (MgSt) is associated with a reduced tensile strength and prolonged disintegration and dissolution times. In the current study, alternative lubricants to MgSt were compared with regard to lubrication efficacy and their impact on tablet properties. The lubricants were combined in different concentrations (0.5-5% w/w) with three fillers (lactose, mannitol and microcrystalline cellulose (MCC)). The high lubrication efficiency of MgSt was associated with the highest reduction of tensile strength. The micronized stearic acid (SA) grades proved good alternatives as they showed a good lubrication efficiency in combination with a limited negative effect on tensile strength. The hydrophobic lubricants (e.g., MgSt and SA) did not prolong disintegration. In contrast, delayed disintegration was observed for sucrose monopalmitate combined with all three fillers and for several other hydrophilic lubricants (sodium lauryl sulfate, poloxamers 188 and P407) combined with MCC. These unexpected findings were explained by the competition-for-water hypothesis. The potential of alternative lubricants to MgSt was demonstrated in this study. Nevertheless, the impact of lubricant addition on process and tablet quality depended on lubricant (type and concentration) and formulation (lubrication need, deformation mechanism and disintegration behavior) properties. Therefore, lubricant selection should be carefully considered in formulation development.

Downstream Processing of Itraconazole:HPMCAS Amorphous Solid Dispersion: From Hot-Melt Extrudate to Tablet Using a Quality by Design Approach. Pharmaceutics 2022; 14:pharmaceutics14071429. [PMID: 35890324 PMCID: PMC9323274 DOI: 10.3390/pharmaceutics14071429] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/01/2022] [Accepted: 07/04/2022] [Indexed: 11/17/2022] Open
Abstract
The downstream processing of hot-melt extruded amorphous solid dispersions (ASDs) into tablets is challenging due to the low tabletability of milled ASDs. Typically, the extrudate strand is sized before milling, as the strand cannot be fed directly into the milling system. At the lab scale, the strand can be sized by hand-cutting before milling. For scaling up, pelletizers or chill roll and flaker systems can be used to break strands. Due to the different techniques used, differences in milling and tablet compaction are to be expected. We present a systematic study of the milling and tableting of an extruded ASD of itraconazole with hypromellose acetate succinate (HPMCAS) as a carrier polymer. The strand was sized using different techniques at the end of the extruder barrel (hand-cutting, pelletizer, or chill roll and flaker) before being milled at varying milling speeds with varying screen sizes. The effects of these variables (sizing technology, milling speed, and screen size) on the critical quality attributes (CQAs) of the milled ASD, such as yield, mean particle size (D50), tablet compaction characteristics, and tablet dissolution, were established using response surface methodology. It was found that the CQAs varied according to sizing technology, with chill roll flakes showing the highest percentage yield, the lowest D50, and the highest tabletability and dissolution rate for itraconazole. Pearson correlation coefficient tests indicated D50 as the most important CQA related to tabletability and dissolution. For certain milling conditions, the milling of hand-cut filaments results in similar particle size distributions (PSDs) to the milling of pellets or chill roll flakes.

Abstract
Internal lubrication can be associated with reduced tabletability. Deformation mechanism, lubricant type, lubricant blending time and paddle speed (PS) of the forced feeder are known to be influenceable factors. This study investigated the effect of lubricant blending time and PS of forced feeders on the tensile strength of lubricated microcrystalline cellulose (MCC) and lactose tablets. Magnesium stearate (MgSt), sodium stearyl fumarate (SSF) and stearic acid (SA) were used as lubricants. Tablets were produced on a compaction simulator and a rotary tablet press to investigate lubricant sensitivity during upscaling. Lubricant sensitivity was found higher for MCC compared to lactose which was attributed to the higher plasticity of MCC. The reduction in tensile strength upon lubricant addition followed the order: MgSt > SSF > SA; which could be linked to particle size, specific surface area and particle shape of the lubricants. Although differences in tensile strength were observed between the lubricant types, comparable ejection forces were obtained. The impact of PS on tensile strength was higher compared to lubricant blending time for both tableting machines. A good correlation of tensile strength and lubricant sensitivity between the compaction simulator and rotary tablet press was observed based on the calculation of paddle passes (NPP).

Abstract
Eudragit® polymers are polymethacrylates highly used in pharmaceutics for the development of modified drug delivery systems. They are widely known due to their versatility with regards to chemical composition, solubility, and swelling properties. Moreover, Eudragit polymers are thermoplastic, and their use has been boosted in some production processes, such as hot melt extrusion (HME) and fused deposition modelling 3D printing, among other 3D printing techniques. Therefore, this review covers the studies using Eudragit polymers in the development of drug delivery systems produced by HME and 3D printing techniques over the last 10 years. Eudragit E has been the most used among them, mostly to formulate immediate release systems or as a taste-masker agent. On the other hand, Eudragit RS and Eudragit L100-55 have mainly been used to produce controlled and delayed release systems, respectively. The use of Eudragit polymers in these processes has frequently been devoted to producing solid dispersions and/or to prepare filaments to be 3D printed in different dosage forms. In this review, we highlight the countless possibilities offered by Eudragit polymers in HME and 3D printing, whether alone or in blends, discussing their prominence in the development of innovative modified drug release systems.

Effect of binder type and lubrication method on the binder efficacy for direct compression. Int J Pharm 2021; 607:120968.

Abstract
The effect of different binders for direct compression on tablet critical quality attributes was investigated. Dicalcium phosphate, lactose and microcrystalline cellulose were used as fillers and combined with ten binders (10, 20 and 30% w/w). Binder properties were linked to tensile strength via partial least square analysis. Tablets containing VA64F and PH105 exhibited the highest tensile strength which was linked to their compaction properties (specific work of compaction, elasticity, cohesion index) and particle size. In contrast, S1500 and E15 exhibited the lowest tensile strength of all binders. Lubrication method influenced the tensile strength as lubricant sensitivity was observed to some extent for all binders. Tensile strength was significantly higher applying external compared to internal lubrication. Fast disintegration was observed for MCC (PH105 and PH200) and starch (S1500 and NMSt) grades, whereas HPC (KEXF and KEF) and E15 resulted in delayed disintegration. Wettability measurements, via determination of contact angle, correlated well with the disintegration behaviour of the binders and can therefore be used as an indicative measurement for tablet disintegration. This study revealed the effect of binder properties, filler type and lubrication method on tablet critical quality attributes. In addition, the potential of dry binder addition for direct compression was highlighted.

Identifying Critical Binder Attributes to Facilitate Binder Selection for Efficient Formulation Development in a Continuous Twin Screw Wet Granulation Process. Pharmaceutics 2021; 13:210.

Abstract
The suitability of pharmaceutical binders for continuous twin-screw wet granulation was investigated as the pharmaceutical industry is undergoing a switch from batch to continuous manufacturing. Binder selection for twin-screw wet granulation should rely on a scientific approach to enable efficient formulation development. Therefore, the current study identified binder attributes affecting the binder effectiveness in a wet granulation process of a highly soluble model excipient (mannitol). For this formulation, higher binder effectiveness was linked to fast activation of the binder properties (i.e., fast binder dissolution kinetics combined with low viscosity attributes and good wetting properties by the binder). As the impact of binder attributes on the granulation process of a poorly soluble formulation (dicalcium phosphate) was previously investigated, this enabled a comprehensive comparison between both formulations in current research focusing on binder selection. This comparison revealed that binder attributes that are important to guide binder selection differ in function of the solubility of the formulation. The identification of critical binder attributes in the current study enables rational and efficient binder selection for twin-screw granulation of well soluble and poorly soluble formulations. Binder addition proved especially valuable for a poorly soluble formulation.

It is Possible to Achieve Tablets With Good Tabletability From Solid Dispersions - The Case of the High Dose Drug Gemfibrozil. Curr Drug Deliv 2020; 18:460-470. [PMID: 33100203 DOI: 10.2174/1567201817666201023121948] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 08/12/2020] [Accepted: 09/25/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Solid Dispersions (SDs) have been extensively used to increase the dissolution of poorly water-soluble drugs. However, there are few studies exploring SDs properties that must be considered during tablet development, like tabletability. Poorly water-soluble drugs with poor compression properties and high therapeutic doses, like gemfibrozil, are an additional challenge in the production of SDs-based tablets. OBJECTIVE This study evaluates the applicability of SDs to improve both tabletability and dissolution rate of gemfibrozil. A SD-based tablet formulation was also proposed. METHODS SDs were prepared by ball milling, using hydroxypropyl methylcellulose (HPMC) as a carrier, according to a 23 factorial design. The formulation variables were gemfibrozil:HPMC ratio, milling speed, and milling time. The response in the factorial analysis was the tensile strength of the compacted SDs. Dissolution rate and solid-state characterization of SDs were also performed. RESULTS SDs showed simultaneous drug dissolution enhancement and improved tabletability when compared to corresponding physical mixtures and gemfibrozil. The main variable influencing drug dissolution and tabletability was the gemfibrozil:HPMC ratio. Tablets containing gemfibrozil- HPMC-SD (1:0.250 w/w) and croscarmellose sodium showed fast and complete drug release, while those containing the same SD and sodium starch glycolate exhibited poor drug release due to their prolonged disintegration time. CONCLUSION SDs proved to be effective for simultaneously improving tabletability and dissolution profile of gemfibrozil. Tablets containing gemfibrozil-HPMC-SD and croscarmellose sodium as disintegrating agent showed improved drug release and good mechanical strength, demonstrating the potential of HPMC-based SDs to simultaneously overcome the poor dissolution and tabletability properties of this drug.

Abstract
The impact of hot-melt extrusion (HME) on the solid-state properties of four methacrylic (Eudragit® L100-55, Eudragit® EPO, Eudragit® RSPO, Eudragit® RLPO) and four polyvinyl (Kollidon® VA64, Kollicoat® IR, Kollidon® SR, and Soluplus®) polymers was studied. Overall, HME decreased Tg but increased electrostatic charge and surface free energy. Packing density decreased with electrostatic charge, whereas Carr’s and Hausner indices showed a peak curve dependency. Overall, HME reduced work of compaction (Wc), deformability (expressed as Heckel PY and Kawakita 1/b model parameters and as slope S′ of derivative force/displacement curve), and tablet strength (TS) but increased elastic recovery (ER). TS showed a better correlation with S′ than PY and 1/b. Principal component analysis (PCA) organized the data of neat and extruded polymers into three principal components explaining 72.45% of the variance. The first included Wc, S′ and TS with positive loadings expressing compaction, and ER with negative loading opposing compaction; the second included PY, 1/b, and surface free energy expressing interactivity with positive loadings opposing tap density or close packing. Hierarchical cluster analysis (HCA) assembled polymers of similar solid-state properties regardless of HME treatment into a major cluster with rescaled distance Cluster Combine Index (CCI) < 5 and several other weaker clusters. Polymers in the major cluster were: neat and extruded Eudragit® RSPO, Kollicoat® IR, Kollidon® SR, Soluplus®, and extruded Eudragit® L100-55. It is suggested that PCA may be used to distinguish variables having similar or dissimilar activity, whereas HCA can be used to cluster polymers based on solid-state properties and pick exchangeable ones (e.g., for sustain release or dissolution improvement) when the need arises.

Abstract
The internal blending of magnesium stearate is often associated with decreasing tensile strengths and longer disintegration and dissolution times. Therefore, external lubrication has gained interest in the pharmaceutical industry as these negative effects could be minimized using this method. In this study, an external lubrication system implemented in a compaction simulator was investigated. The influence of 2 process parameters related to the external lubrication system, spraying time and atomizing pressure, on the responses was studied using 4 common fillers and 2 model drugs. While the parameters of the external lubrication system had a significant impact on the ejection forces, no negative effect was observed on the tensile strength and disintegration time as similar values were obtained compared to non-lubricated experiments. Moreover, equal or lower ejection forces were obtained for external lubrication using a lower concentration of magnesium stearate compared to internal lubrication, where a decrease in tensile strength and prolonged disintegration was noticed for most formulations. The observed results could be correlated to the wall friction angle, compaction properties and tablet brittleness index of the raw materials and blends. This study showed the potential of external lubrication as an alternative lubrication method for lubricant-sensitive formulations.

Abstract
The pharmaceutical industry has found new applications for the use of continuous processing for the manufacture of new therapies currently in development. The transformation has been encouraged by regulatory bodies as well as driven by cost reduction, decreased development cycles, access to new chemistries not practical in batch, improved safety, flexible manufacturing platforms, and improved product quality assurance. The transformation from batch to continuous manufacturing processing is the focus of this review. The review is limited to small, chemically synthesized organic molecules and encompasses the manufacture of both active pharmaceutical ingredients (APIs) and the subsequent drug product. Continuous drug product is currently used in approved processes. A few examples of production of APIs under current good manufacturing practice conditions using continuous processing steps have been published in the past five years, but they are lagging behind continuous drug product with respect to regulatory filings.

Different effects of silica added internal or external on in vitro dissolution of indomethacin hot-melt extrudates. Int J Pharm 2017; 534:272-278. [PMID: 29074389 DOI: 10.1016/j.ijpharm.2017.10.041] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2017] [Revised: 10/15/2017] [Accepted: 10/21/2017] [Indexed: 01/26/2023]
Abstract
The purpose of this work was to investigate the effect on the dissolution behavior when silica was added in different ways. The solid dispersion was prepared by hot-melt extrusion (HME) using indomethacin (IND) as a model drug and Kollidon VA64 as a carrier. In order to change the dissolution behavior, the silica was added during or after the HME respectively, to obtain the corresponding silica internal-added solid dispersion (InSD) and silica external-added solid dispersion (ExSD). According to the results, the internal-added silicon dioxide could reduce the dissolution rate from 66.91%/h to 24.12%/h and the water infiltration rate from 0.37mm/h to 0.16mm/h in the phosphate buffer solution (PBS) of pH 6.8, so the formulation of InSD had a significant sustained release effect. But the infiltration rate of the ExSD was increased to 13.22mm/h when silica was added external, and the density of VA64 in the powder was decreased from 541.87mg/cm3 to 141.87mg/cm3, leading to a weak resistance to the external force, and the powder was easy to be dispersed after wetted by water so that the formulation of ExSD had a relatively higher dissolution rate. This phenomenon was more visible when the phosphate buffer solution was changed to pH 5.6 in which the API was more difficult to be dissolved. Accordingly, different addition ways of aerosil would change release behavior of the HME preparation.
