A dual strategy to improve psychotic patients’ compliance using sustained release quetiapine oral disintegrating tablets.
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: […]
Design and evaluation of microwave-treated orally disintegrating tablets containing polymeric disintegrant and mannitol.
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 […]
Phenylalanine-free taste-masked orodispersible tablets of fexofenadine hydrochloride: development, in vitro evaluation and in vivo estimation of the drug pharmacokinetics in healthy human volunteers.
Abstract CONTEXT: Fexofenadine hydrochloride (FXD) is a slightly soluble, bitter-tasting, drug having an oral bioavailability of 35%. The maximum plasma concentration is reached 2.6 h (T(max)) post-dose. OBJECTIVE: Developing taste-masked FXD orodispersible tablets (ODTs) to increase extent of drug absorption and reduce Tmax. METHODS: Taste masking was achieved via solid dispersion (SD) with chitosan (CS) or […]
Design and evaluation of fast dissolving tablets containing diclofenac sodium using fenugreek gum as a natural superdisintegrant.
Abstract OBJECTIVE: To formulate diclofenac sodium as fast dissolving tablets (FDTs) using fenugreek gum as a natural superdisintegrant which also possess anti-inflammatory activity. METHODS: An attempt was made to extract the fenugreek gum and evaluated it for various physicochemical characterizations. The swelling index and viscosity of fenugreek gum was 221% and 293.4 mpa.s respectively. FDTs […]
Spray drying of drug-swellable dispersant suspensions for preparation of fast-dissolving, high drug-loaded, surfactant-free nanocomposites.
Abstract Bioavailability of a poorly soluble drug can be improved by preparing a drug nanosuspension and subsequently drying it into nanocomposite microparticles (NCMPs). Unfortunately, drug nanoparticles aggregate during milling and drying, causing incomplete recovery and slow dissolution. The aim of this study is to investigate the impact of various classes of dispersants on drug dissolution […]
The Solubility of Microcrystalline Cellulose in Sodium Hydroxide Solution Is Inconsistent with International Specifications.
Abstract Microcrystalline cellulose (MCC) is used globally as an inactive ingredient in food and nutraceutical products and is commonly used as a food additive. To confirm the conformity of MCC to the solubility requirements stipulated in international specifications, the solubilities of commercially available MCC products were tested in sodium hydroxide (NaOH) solution. All of the samples […]
