Diffuse reflectance near infrared-chemometric methods development and validation of amoxicillin capsule formulations.
Abstract OBJECTIVE: The aim of present study was to establish near infrared-chemometric methods that could be effectively used for quality profiling through identification and quantification of amoxicillin (AMOX) in formulated capsule which were similar to commercial products. In order to evaluate a large number of market products easily and quickly, these methods were modeled. MATERIALS […]
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 […]
Experimental studies on the effect of moisture content and volume resistivity on electrostatic behaviour of pharmaceutical powders.
Abstract Pharmaceutical powders are mainly organic materials and are likely to be charged due to repeated inter-particle and particle-wall contacts during industrial processes. This study experimentally investigated the effect of moisture content (ranging from approximately 1.8 to 30wt.%) on tribocharging behaviour of pharmaceutical granules, as well as their apparent volume resistivity. The tribocharging behaviour of pharmaceutical granules was investigated using […]
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 […]
Formulation and Optimization of Multiparticulate Drug Delivery System Approach for High Drug Loading.
Abstract The aim of the present work was to develop and optimize multiparticulate formulation viz. pellets of naproxen by employing QbD and risk assessment approach. Mixture design with extreme vertices was applied to the formulation with high loading of drug (about 90%) and extrusion-spheronization as a process for manufacturing pellets. Independent variables chosen were level […]
