Abstract

Principles of the combination of chemically complementary grades of Eudragit (R) copolymers in peroral, matrix, and reservoir types of solid dosage forms with modified release [tablets, microspheres, (micro) pellets] and their manufacturing technology (including film coatings) are considered. Modified drug release is achieved due to the interaction between reactive groups of copolymer pairs, which controls the drug release process both inside matrices and within multilayers or combined coatings. Analysis of these processes has key significance for developing (meth) acrylate polycomplexes, which could be synthesized in both aqueous and organic media, as new classes of drug carriers for constructing modern peroral drug delivery systems.

Aggregation behaviour of poly(fluoro(meth)acrylate)-block-poly(acrylic acid) copolymers at the air/water interface

Alexandra Grigoreva, Kseniia Tarankova, Olga Zamyshlyayeva, Sergey Zaitsev

Summary: The formation of monolayers of PFA-b-PAA amphiphilic copolymers at the air/water interface was characterized using Langmuir film balance technique and atomic force microscopy. Both internal and external effects on the aggregation behavior of the copolymers were considered. The study found that the structure of the copolymer and the pH and salt concentration of the subphase have significant impacts on the surface behavior of the copolymers.

Alternating [1.1.1]Propellane-(Meth)Acrylate Copolymers: A New Class of Dielectrics with High Energy Density for Film Capacitors

Xiang-Yue Cheng, Qi-Kun Feng, Zhi-Min Dang, Fu-Sheng Du, Zi-Chen Li

Summary: This paper reports the synthesis and molar mass control of three alternating [1.1.1]propellane-(meth)acrylate copolymers. The copolymers exhibit high thermal stability and semi-crystalline properties. The introduction of the rigid bicyclo[1.1.1]pentane unit into the polymer backbone enhances the dielectric constants and ensures high breakdown strength, resulting in extraordinary energy storage performance.

Summary: Terpenes are considered ideal candidates for sustainable polymer feedstocks due to their natural abundance and availability from existing waste streams. By using RAFT control, well-defined polymers and precise di- and multiblock copolymer architectures can be synthesized. A wide range of T-g values are observed for terpene (meth)acrylate homopolymers, which can be utilized to create renewably-sourced hard-soft block copolymers.

Preparation and release behavior of poly(methyl methacrylate-co-methacrylic acid)-based electrospun nanofibrous mats loaded with doxorubicin

Roberto Lopez-Munoz, Raul Guillermo Lopez, Hened Saade, Angel Licea-Claverie, Francisco Javier Enriquez-Medrano, Graciela Morales, Daniel Grande

Summary: A drug-loaded electrospun mat has been found to have potential for cancer treatment after surgery. Using a semi-continuous heterophase polymerization method, a methacrylic copolymer called P(MMA-co-MAA) was synthesized as a carrier for the anticancer drug doxorubicin hydrochloride (DOX). Confocal microscopy images indicated that the copolymer was more effective at incorporating the drug than the ES100 nanofibers. The in-vitro release profiles showed that the synthesized copolymer had a lower release rate compared to the ES100 copolymer, suggesting its potential for sustained and prolonged drug release.

Hydrosilylation-Promoted Group Transfer Polymerization of Ethyl Sorbate: A Controlled/Living System Applied to the Synthesis of an ?-End Functionalized Polymer and a Triblock Copolymer with a (Meth)acrylate Polymer

Liang Xu, Yu Takagi, Xiangming Fu, Yanqiu Wang, Atsushi Narumi, Shin-ichiro Sato, Xiande Shen, Toyoji Kakuchi

Summary: The hydrosilylation-promoted group transfer polymerization (GTP) was used to investigate the polymerization method, preparation of well-defined (co)polymers, and the controlled/living property of ethyl sorbate (ES). The two methods, single catalyst and catalyst switch, were employed to produce well-defined poly(ethyl sorbate) (PES). The kinetic experiments showed that the propagation rate kp for t-Bu-P4-catalyzed GTP is higher than that for B(C6F5)3. Alpha-end-functionalized PES was synthesized via the hydrosilylation-promoted GTP using a sorbate ester with a functional group as the moisture-stable latent initiator. Furthermore, the controlled/living property enabled the GTP of ES with MMA and nBA to produce AB-diblock copolymers and ABA-and ABC-triblock copolymers composed of PES, PMMA, and PnBA.

The effect of biomaterials of cross carmellose sodium and Eudragit S-100 as model polymers on colon targeted drug release in different dosage forms

R. B. Sharma, V Arora, S. Arora, A. Kapila, R. Sharma

Summary: The aim of this study was to investigate the role of biomaterials cross carmellose sodium and Eudragit S100 in controlling drug release to the colon. Nine formulations with different polymer concentrations were prepared, and coating process using Eudragit S100 and various excipients was performed. One formulation showed a release of 99.4% of the drug in the colon within 36 hours, indicating excellent release performance.

Summary: A water-soluble form of haloperidol was obtained by coaggregation with calix[4]resorcinol to form vesicular nanoparticles. The nanoparticles showed mucoadhesive and thermosensitive properties, making them potentially effective drug delivery systems. In pharmacological studies, haloperidol formulated with calix[4]resorcinol exhibited a cataleptogenic effect in rats both when administered intranasally and intraperitoneally.
