[Influence of the mesh of extrusion dies on the properties of cores intended for the preparation of pellets with controlled glucose release].
Abstract Diabetes mellitus and its compensation are accompanied by serious complications. One of them is hypoglycaemia, which occurs in patients treated with insulin and/or certain peroral antidiabetics. Hypoglycaemic episodes can be prevented by a dosage form with controlled release of glucose. The pellet cores of four compositions and three different sizes corresponding to the diameter […]
Preparation of benznidazole pellets for immediate drug delivery using the extrusion spheronization technique.
Abstract Recent advances in the treatment of Chagas disease have followed combinations of drugs that act synergistically against infection, predominantly including benznidazole (BNZ) and azoles derivatives. Possible incompatibilities between these drugs, slow dissolution of BNZ and dose adjustment difficulties are technological obstacles to the development of multidrug formulations. Thus, in the present study, BNZ pellets […]
Self-emulsifying Pellets Prepared by Extrusion/Spheronization: In vitro/In vivo Evaluation.
Abstract AIMS: The purpose of the current study was to investigate the feasibility of producing solid self-emulsifying pellets using the extrusion/spheronization technique with an aim to increase the bioavailability of selected drug and also to encounter the problems associated with liquid lipid formulations. Self-emulsifying formulations are experiencing a very active development as reflected by the […]
Microcrystalline cellulose: Isolation, characterization and bio-composites application-A review.
Abstract Considering its widespread usage in various fields, such as food, pharmaceutical, medical, cosmetic and polymer composites industries, microcrystalline cellulose (MCC) is becoming impellent due to increasing demand of alternatives to non-renewable and scarce fossil materials. Although it still suffers from some drawbacks, MCC has recently gained more interest owing to its renewability, non-toxicity, economic value, biodegradability, high […]
Preparation and physicochemical characterization of matrix pellets containing APIs with different solubility via extrusion process.
Abstract In this study, a multiparticulate matrix system was produced, containing two different active pharmaceutical ingredients (APIs): enalapril-maleate and hydrochlorothiazide. The critical control points of the process were investigated by means of factorial design. Beside the generally used microcrystalline cellulose, ethylcellulose was used as matrix former to achieve modified drug release ensured by diffusion. The matrix pellets were […]
Approaches to developing fast release pellets via wet extrusion-spheronization.
Abstract Microcrystalline cellulose (MCC) is widely regarded as the excellent choice to manufacture pellets via wet extrusion-spheronisation (ES) process due to its excellent water uptake capability, water holding capacity, desirable rheological properties, cohesiveness and plasticity etc. Nevertheless, in spite of all these advantages, limitations associated with the application of MCC also have been reported. The most […]
Formulation and optimization of Lansoprazole pellets using factorial design prepared by extrusion-spheronization technique using Carboxymethyl tamarind kernel powder.
Abstract BACKGROUND: In the present study, Lansoprazole pellets were prepared employing a novel excipient Carboxymethyl tamarind kernel powder (CMTKP) using extrusion-spheronization technique. Pellet formulation was optimized for formulation parameters (concentration of microcrystalline cellulose, CMTKP, croscarmellose sodium and isopropyl alcohol). METHODS: Process parameters (speed and duration of spheronization) were optimized using factorial design. The pellets were evaluated […]
