Abstract Near-infrared spectroscopy (NIRS) is a valuable tool in the pharmaceutical industry, presenting opportunities for online analyses to achieve real-time assessment of intermediates and finished dosage forms. The purpose of this work was to investigate the effect of experimental designs on prediction performance of quantitative models based on NIRS using a five-component formulation as a […]

Abstract The purpose of the present study was to develop oral dispersible tablets containing prednisolone (PDS)-loaded chitosan nanoparticles using microcrystalline cellulose (MCC 101), lactose, and croscarmellose sodium (CCS). The PDS-loaded chitosan nanoparticles were formulated by ionotropic external gelation technique in order to enhance the solubility of PDS in salivary pH. Prepared nanoparticles were used for the development […]

Abstract The objective of this study was to evaluate and compare the effect of four superdisintegrants such as croscarmellose sodium (Ac-Di-Sol), crospovidone (Kollidon CL and with smaller particle sizes Kollidon CL-F), sodium starch glycolate (Explotab) in combination with β-lactose and microcrystalline cellulose (Avicel PH-102) as base excipients exhibiting properties of directly compressed tablets and increasing the disintegration […]

Abstract The objective of the study was to identify the extragranular component requirements (level and type of excipients) to develop an immediate release tablet of solid dispersions prepared by hot melt extrusion (HME) process using commonly used HME polymers. Solid dispersions of compound X were prepared using polyvinyl pyrrolidone co-vinyl acetate 64 (PVP VA64), Soluplus, […]

Abstract Tablets which were binary mixtures of pioglitazone hydrochloride (PioHCl) with magnesium stearate (MgSt), croscarmellose sodium(CCS), microcrystalline cellulose, or lactose monohydrate were prepared. Two sets of experiments, using intact tablets, were performed. (i) Tablets containing PioHCl (90% w/w) and MgSt were exposed to 25 or 40 °C and 75% RH in a custom-built temperature/humidity chamber. In […]

Abstract BACKGROUND: Microcrystalline cellulose (MCC) is an excellent excipient for production of pellets by extrusion spheronization. However, it causes slow release rate of poorly water soluble drugs from pellets. Co-processed excipient prepared by spray drying (US 4,744,987; US 5686107; WO 2003/051338) and co-precipitation technique (WO 95/17831) are patented. OBJECTIVE: The objective of present study was to […]

Abstract The present investigation was carried out to develop and characterize a multifunctional co-processed excipient for improving the compressibility of poorly compressible drugs. Etodolac was used as a model drug. Microcrystalline cellulose (MCC), lactose monohydrate (lactose), and StarCap 1500 (StarCap) were selected as components of the co-processed excipient. The spray drying method was used for co-processing of […]

Abstract OBJECTIVES: The study evaluated the quality of compounded sachets and hard gelatine capsules and their feasibility in paediatric drug administration. METHODS: Commercial tablets were compounded to sachets and capsules in hospital environment, and the uniformity of content and simulated drug dose were determined. KEY FINDINGS: Compounded formulations were successfully obtained for a range of […]

Abstract This work aims to employ fused deposition modelling 3D printing to fabricate immediate release pharmaceutical tablets with several model drugs. It investigates the addition of non-melting filler to methacrylic matrix to facilitate FDM 3D printing and explore the impact of (i) the nature of filler, (ii) compatibility with the gears of the 3D printer and iii) […]

Abstract The bilayer tableting technology is gaining more acceptance in the drug industry, due to its ability to improve the drug delivery strategies. It is currently assessed by the European Pharmacopoeia, that the mechanical strength of tablets can be evaluated using a diametral breaking tester. This device applies a force diametrically, and records the tablet […]
