The use of potassium iodide (KI) as a protective agent against accidental radioactive exposure is well established. In this study, we aimed to prepare a KI tablet formulation using a direct compression method. We utilized Design of Experiment (DoE)/mixture design to define the best formulation with predetermined physical qualities as to its dissolution, hardness, assay, disintegration, and angl...

The terahertz gap has a frequency ranges from approximately 0.3 THz to approximately 10 THz in the electromagnetic spectrum which is in between microwave and infrared. The terahertz radiations are invisible to naked eye. In comparison with x-ray they are intrinsically safe, non-destructive and non-invasive. Terahertz spectroscopy enables 3D imaging of structures and materials, and the measureme...

background: azithromycin (azm) is used in periodontal infections. the present study compared gingival crevicular fluid concentration of azithromycin of two pharmaceutical companies through the hplc method. methods: two groups (n=15) of healthy volunteers participated in this study. the first group received an imported azithromycin (imazm) tablet (250 mg, po) and the second group received an azi...

Counterfeit pharmaceutical drugs imply an increasing threat to the global public health. It is necessary to have systems to control the products that reach the market and to detect falsified medicines. In this work, molecules in several pharmaceutical tablets were directly analyzed using nanospray desorption electrospray ionization mass spectrometry (nano-DESI MS). Nano-DESI is an ambient surfa...

The article studies whether training prior to laboratory work (with a multimedia interactive programme), as a complement to the traditional practicaltheoretical teaching of tablet manufacturing, has brought advantages to pharmaceutical technology learning and, in consequence, increased the quality of the tablets produced by the students in the educational pilot plant. Evaluation is a key aspect...
