Abstract In the past few years, there are number of researchers carrying out their research on the excipients derived from polysaccharides and some of these researches show that natural excipients are comparable and can serve as an alternative to the synthetic excipients. Hence, the objectives of this research are to characterize the naturally sourced chickpea […]

Abstract Quetiapine (QT) is a short acting atypical antipsychotic drug effective in schizophrenia and bipolar disorder. This study aims at designing a novel dosage form of sustained release taste-masked QT orally disintegrating tablets (ODTs) based on solid lipid micro-pellets (SLMPs). QT SLMPs were prepared using the hot melt extrusion technique and utilizing three lipid carriers: […]

Abstract Fast dissolving tablets of clonazepam were prepared by sublimation method with a view to enhance patient compliance. A 3(2) full factorial design was applied to investigate the combined effect of two formulation variables: amount of croscarmellose sodium and camphor. Croscarmellose sodium (2-8% w/w) was used as superdisintegrant and camphor (20-40% w/w) was used as subliming agent, to increase […]

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 aim of this study was to investigate the use of inclusion complexation technique employing β-cyclodextrin in improving the dissolution profile of candesartan cilexetil, a BCS class-II drug, and to formulate the inclusion complex into orodispersible tablets. The inclusion complexes were formed by physical mixing, kneading, coevaporation, and lyophilisation methods. Inclusion complexes were characterized […]

Abstract With the aim of directly predicting the functionality and mechanism of disintegrants during the disintegration and dissolution of tablets, we investigated an analysis method based on available surface area, which is the surface area of a drug in a formulation in direct contact with the external solvent during dissolution. We evaluated the following disintegrants […]

Abstract Microwave (MW) treatment was used to develop a formulation process for the preparation of wet molded orally disintegrating tablets (ODTs) consisting of mannitol and polymeric disintegrant with improved hardness and disintegration properties. The wet molded tablets were prepared in accordance with the conventional methods and subsequently heated by MW irradiation to induce the swelling […]

Abstract The objective of the current work was to study an observed incompatibility between croscarmellose sodium and basic excipients in a tablet formulation. Significant dissolution slowdown was observed for alkaline tablet compositions of an acid-labile drug containing croscarmellose sodium (CCS) as a disintegrant. The severity of the dissolution slowdown was directly proportional to both the degree of alkalinity and […]

Abstract PURPOSE: The demand for melt-in-mouth tablets (MMTs) has been rapidly growing during the last decade, especially for the elderly and children who have swallowing difficulties, to avoid first-pass metabolism and quick drug entry into the systemic circulation. MATERIALS AND METHODS: In this work, a new approach has been tried to prepare MMTs using a […]

Abstract Pharmaceutical excipients should not disturb the effects of drug therapy. In recent years, however, it has been reported that excipients induce some changes to the tight junction (TJ) and P-glycoprotein (P-gp), which can affect drug disposition. In this study, we examined the effects of 20 common pharmaceutical excipients from different classes on mucosal membrane […]
