Development of oral dispersible tablets containing prednisolone nanoparticles for the management of pediatric asthma.
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 […]
DISSOLUTION PROPERTIES AND KINETIC STUDY OF SULFADIMIDINE AND TRIMETHOPRIM TABLETS CONTAINING FOUR DIFFERENT SUPERDISINTEGRANTS.
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 […]
Development of Tablet Formulation of Amorphous Solid Dispersions Prepared by Hot Melt Extrusion Using Quality by Design Approach.
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, […]
[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 […]
Using the Slug Mucosal Irritation Assay to Investigate the Tolerability of Tablet Excipients on Human Skin in the Context of the Use of a Nipple Shield Delivery System.
Abstract PURPOSE: Neonates are particularly challenging to treat. A novel patented drug delivery device containing a rapidly disintegrating tablet held within a modified nipple shield (NSDS) was designed to deliver medication to infants during breastfeeding. However concerns exist around dermatological nipple tolerability with no pharmaceutical safety assessment guidance to study local tissue tolerance of the […]
Investigation of Spatial Heterogeneity of Salt Disproportionation in Tablets by Synchrotron X-ray Diffractometry.
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 […]
Terahertz study on porosity and mass fraction of active pharmaceutical ingredient of pharmaceuticaltablets.
Abstract In this study, terahertz time-domain spectroscopic (THz-TDS) technique has been used to ascertain the change in the optical properties, as a function of changing porosity and mass fraction of active pharmaceutical ingredient (API), of training sets of pharmaceutical tablets. Four training sets of pharmaceutical tablets were compressed with microcrystalline cellulose (MCC) excipient and indomethacin API by varying either the porosity, height, and […]
Enabling the Tablet Product Development of 5-Fluorocytosine by Conjugate Acid Base Cocrystals.
Abstract 5-Fluorocytosine (FC) is a high-dose antifungal drug that challenges the development of a tablet product due to poor solid-state stability and tabletability. Using 2 pharmaceutically acceptable conjugate acid base (CAB) cocrystals of FC with HCl and acesulfame, we have developed commercially viable high loading FC tablets. The tablets were prepared by direct compression using […]
Formulation development and comparative in vitro study of metoprolol tartrate (IR) tablets.
Abstract The objective of the present work was to develop Immediate Release (IR) tablets of Metoprolol Tartrate (MT) and to compare trial formulations to a reference product. Six formulations (F1-F6) were designed using central composite method and compared to a reference brand (A). Two marketed products (brands B and C) were also evaluated. F1-F6 were […]
Effect of colloidal silica on rheological properties of common pharmaceutical excipients.
Abstract In pharmaceutical industry, the use of lubricants is mostly based on historical experiences or trial and error methods even these days. It may be demanding in terms of the material consumption and may result in sub-optimal drug composition. Powder rheology enables more accurate monitoring of the flow properties and because the measurements need only a small […]
