Abstract
Polyethylene oxide (PEO) is a widely used polymer in the development of abuse-deterrent oral formulations. Different manufacturing processes including direct compression (DC) followed by sintering, wet granulation (WG) followed by compression and sintering, and hot melt extrusion (HME) can be used to manufacture abuse-deterrent oral drug products. Three different manufacturing processes (DC, WG, HME) were evaluated to test the retention of their abuse-deterrent features following attempts to grind the tablets or extrudates. In vitro drug release studies were conducted on 10% and 32% drug-loaded tablets/extrudates prepared using these manufacturing methods, and the release profiles from all formulations showed good extended-release properties. Drug content analysis on the granules obtained from tablets prepared by direct compression showed non-uniform drug distribution where an unexpectedly high drug content was present in the smallest size (< 250 µm) granules, sizes which are likely to be inhaled by abusers. Granules from tablets prepared by wet granulation showed improved drug distribution across all granule sizes formed after grinding. Drug content testing on the granules obtained from extrudates prepared using hot melt extrusion showed excellent drug content uniformity along with sufficient strength to resist grinding into smaller particles. The retention of the abuse-deterrent properties of a dosage form following attempts to extract or abuse the drug is an important product characteristic, and the product design, formulation components, and manufacturing processes can all play critical roles in the retention of the desired abuse-deterrent properties.

Abstract
Most of published reviews of twin-screw extrusion focused on its application for enhancing the bioavailability of amorphous solid dispersions while few of them focused on its use for manufacturing sustained-release oral dosage forms and medical implants, despite the considerable interest and success this process has garnered both in academia and in the pharmaceutical industry. Compared to conventional batch processing, twin-screw extrusion offers the advantages of continuous processing and the ability to prepare oral dosage forms and medical implants that have unique physicochemical and drug release attributes. This review provides an in-depth analysis of the formulation composition and processing conditions of twin-screw extrusion and how these factors affect the drug release properties of sustained-release dosage forms. This review also illustrates the unique advantages of this process by presenting case studies of a wide variety of commercial sustained-release products manufactured using twin-screw extrusion.

Abstract
AIMS In the field of anaesthesia and intensive care, the controlled release systems capable of delivering constantly local anaesthetics are of interest because of the advantages brought to pain management. In this paper we presented the release profiles by usage of siloxane matrices of two common local anaesthetics, lidocaine and bupivacaine, analysed in vitro. METHODS The siloxane matrices were obtained in accordance with the methods described in the specialized literature, tetraethoxysilane (TEOS) and tetramethoxysilane (TMOS) were used as precursors. Lidocaine and bupivacaine were encapsulated in the synthesized gels. The controlled release was performed in vitro artificial systems in which temperature (30°C, 36.5°C, 40°C) and pH (6, 7, 8) have varied. RESULTS Following the analysis of the artificial systems similar profiles were highlighted for both local anaesthetics. Statistically significant differences were identified (p < 0.05) for systems where the release occurred at temperatures above 36.5°C. There were no statistically significant differences regarding the influence of pH, the type of the entrapped anaesthetic or the type of the precursor used in the synthesis of siloxane matrices. CONCLUSIONS According to this experimental study, the pH, the type of precursor or the type of anaesthetic does not statistically influence the release profile from the studied system. In conclusion, these systems are promising for obtaining pharmaceutical preparations which can be used in current clinical practice. Several studies on controlled release siloxane systems should be carried out both in vitro and in vivo in order to exclude possible toxicity and histopathological effects.

[PMID: 26142246 DOI: 10.1016/j.ijpharm.2015.06.045] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2015] [Revised: 06/23/2015] [Accepted: 06/24/2015] [Indexed: 10/24/2022]
Abstract
We present hot melt extrusion (HME) for the design of floating multiparticulates. Metoprolol succinate was selected as the model drug. Our foremost objective was to optimize the components Eudragit(®) RS PO, polyethylene oxide (PEO) and hydroxypropyl methylcellulose (HPMC) to balance both buoyancy and controlled release. Gas generated by sodium bicarbonate in acidic medium was trapped in the polymer matrix to enable floating. Eudragit(®) RS PO and PEO with sodium bicarbonate resulted in multiparticulates which exhibited rapid flotation within 3 min but inadequate total floating time (TFT) of 3h. Addition of HPMC to the matrix did not affect floating lag time (FLT), moreover TFT increased to more than 12h with controlled release of metoprolol succinate. Floating multiparticulates exhibited t50% of 5.24h and t90% of 10.12h. XRD and DSC analysis revealed crystalline state of drug while FTIR suggested nonexistence of chemical interaction between the drug and the other excipients. The assay, FLT, TFT and the drug release of the multiparticulates were unchanged when stored at 40°C/75%RH for 3 months confirming stability. We present floating multiparticulates by HME which could be extrapolated to a range of other drugs. Our approach hence presents platform technology for floating multiparticulates.
