Kondo K, Ohta S, Niwa T. Preparation of sustained-release tablets using a solventless-mixing tablet coating technique: Particle design of dry ammonioalkyl methacrylate copolymer latex with high coating performance using sodium lauryl sulfate. Eur J Pharm Biopharm 2023:S0939-6411(23)00115-7. [PMID: 37172695 DOI: 10.1016/j.ejpb.2023.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 04/22/2023] [Accepted: 05/01/2023] [Indexed: 05/15/2023]
Abstract
The aim of this study was to produce sustained-release tablets by V-shaped blending of polymer and tablets without using solvents or heating, and we investigated the design of polymer particles with high coating performance by modifying the structure of the particles using sodium lauryl sulfate. Dry-latex particles of ammonioalkyl methacrylate copolymer were prepared by adding the surfactant into aqueous latex, followed by freeze drying. The resulting dry latex was mixed with tablets (1:10) using a blender and the resulting coated tablets were characterized. Tablet coating by the dry latex was promoted as the weight ratio of surfactant to polymer increased. At a surfactant ratio of 5%, deposition of the dry latex was most effective and the resulting coated tablets (annealed at 60 °C/75%RH for 6 h) exhibited sustained-release characteristics over a period of 2 h. The addition of SLS prevented coagulation of colloidal polymer in the freeze drying, resulting in a loose-structured dry latex. This latex was easily pulverized by V-shaped blending with tablets and the resulting fine particles with high adhesiveness were deposited on the tablets. However, at a surfactant ratio of 10%, the coating of dry latex decreased due to reduced adhesiveness.

Drug-plasticizer interactions causing solid state transitions of rifaximin. Int J Pharm 2022; 625:122128. [PMID: 35995318 DOI: 10.1016/j.ijpharm.2022.122128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 08/03/2022] [Accepted: 08/16/2022] [Indexed: 11/22/2022]
Abstract
Solid phase interactions are often the reason for incompatibilities in solid dosage forms. A special situation occurs, if the incompatible compounds are able to migrate within the solid matrix. This study describes for the first time the migration of a plasticizer from the coating into the core and its interaction with the active ingredient located there. This behavior was observed in rifaximin gastro-resistant granules and resulted in the formation of solvates with altered dissolution behavior. For a detailed study, rifaximin was incubated with five plasticizers of different solubility and miscibility as well as different molecular geometry (linear vs branched), (dibutyl sebacate, tributyl citrate, triacetin, polyethylene glycol 400, and propylene glycol). The resulting solid states were analyzed by means of PXRD, supported by thermogravimetric analysis, infrared spectroscopy, and quantitative H NMR. No direct correlation could be demonstrated between the resulting type of solvate/hydrate and the affinity of rifaximin with the respective plasticizers. Interestingly all plasticizers that are able to form type I solvates/hydrates have linear structures. This common feature, which distinguishes them from the more bulky TAC and TBC, seems to be a key characteristic. Rifaximin-PG-solvate formation was not only detected after direct incubation trials, but also observed in enteric coated granules.

Abstract
3D printing is an innovative manufacturing technology with great potential to revolutionise solid dosage forms. Novel features of 3D printing technology confer advantage over conventional solid dosage form manufacturing technologies, including rapid prototyping and an unparalleled capability to fabricate complex geometries with spatially separated conformations. Such a novel technology could transform the pharmaceutical industry, enabling the production of highly personalised dosage forms with well-defined release profiles. In this work, we review the current state of the art of using additive manufacturing for predicting and understanding drug release from 3D printed novel structures. Furthermore, we describe a wide spectrum of 3D printing technologies, materials, procedure, and processing parameters used to fabricate fundamentally different matrices with different drug releases. The different methods to manipulate drug release patterns including the surface area-to-mass ratio, infill pattern, geometry, and composition, are critically evaluated. Moreover, the drug release mechanisms and models that could aid exploiting the release profile are also covered. Finally, this review also covers the design opportunities alongside the technical and regulatory challenges that these rapidly evolving technologies present.

Miscibility characterization of zein/methacrylic acid copolymer composite films and plasticization effects. Int J Pharm 2021; 601:120498.

Abstract
Composite films have gained interest for producing films with optimal properties, without the need of chemical modification. Miscibility of components in the film is important for attaining reproducible and consistent film properties. This study used several techniques, i.e. differential scanning calorimetry, Fourier transform infrared spectroscopy and Raman spectroscopy to understand the degree of miscibility of components and its impact on morphology and mechanical properties of the composite film prepared by casting the blend of zein and methacrylic acid copolymer (Eudragit® L100-55). The effects of composition and plasticization by triethyl citrate and polyethylene glycol 1000 were explored. The results demonstrate the miscibility of zein and methacrylic acid copolymer at a molecular level; and the phase behavior of polymer blends is modified by plasticization. Polyethylene glycol 1000 is more compatible with the polymer blend. Its plasticization effect is associated with an increase in β-sheets. Understanding the miscibility between the plasticizer and the polymer blend allows the ability to predict and control mechanical properties of the zein/methacrylic acid copolymer composite film, in particular when the plasticizer level is changed.

Abstract
The oral delivery of amphotericin B (AmB) has remained a challenge due to its low solubility, permeability, and instability in gastric acidic pH. To solve these issues, herein, we reported a novel approach of using nanostructured lipid carriers (NLCs) and NLCs coating with Eudragit®L100-55 (Eu-NLCs) for the oral delivery of AmB. This study aimed to compare their ability in protecting the drug from degradation in gastrointestinal fluids and permeation enhancement in Caco-2 cells. Uncoated NLCs and Eu-NLCs possessed a mean particle size of ∼180 and ∼550 nm, with a zeta potential of ∼-30 and ∼-50 mV, respectively. Both NLCs demonstrated an AmB entrapment efficiency up to ∼75%. They possessed significantly greater AmB water solubility than the free drug by up to 10-fold. In fasted state simulated gastric fluid, Eu-NLCs provided significantly greater AmB protection from acidic degradation than uncoated NLCs. In fasted state simulated intestinal fluid, both uncoated and Eu-NLCs showed a fast release characteristic. Caco-2 cells permeation studies revealed that uncoated NLCs provided significantly higher apparent permeation coefficient (P app) value than Eu-NLCs. Moreover, after 6 months of storage at 4 °C in the absence of light, the physicochemical stabilities of the lyophilized uncoated and Eu-NLCs could be maintained. In conclusion, the developed NLCs and Eu-NLCs could be a potential drug delivery system in improving the oral bioavailability of AmB.
