Human population bears a similarity to an extent of 99.9%, however mere 0.1% of variability also creates large differences in personal make-up owing to several hereditary and environmental factors. Conventionally, development of healthcare modalities like diagnostics and therapeutics has been by mass production assuming uniformity in characteristics of recipient population. Due to the inherent variability in each individual clinical response to diagnostic and therapeutic products vary greatly...

Abstract Thermoresponsive polymers are a class of smart materials that exhibit change in their physical properties with temperature, which make them unique and useful materials in a wide range of biomedical applications. Soluplus®, a thermoresponsive block graft copolymer with poly(vinyl acetate) PVAc and poly(vinyl caprolactam) PVCL block grafted on a poly(ethelyne glycol) PEG backbone in a ratio of 30:57:13 respectively, is marketed by BASF Corporation, it aids in solubilizing and increasing...

Abstract The aim of this study was to prepare controlled-release (CR) granules with suitable particle strength, flowability, particle size distribution (PSD) and density characteristics for blending with other excipients. We also wanted these CR granules to contain large quantities of active pharmaceutical ingredient (API). A high shear mixer was used to mix an API with various polymers at various feed ratios, and the resulting granulated materials were sprayed with solvent. The wet granules...

Abstract The purpose of the present study was to develop a near-infrared spectroscopy (NIRS) method to quickly, accurately, and precisely evaluate and control the coating process of the low dose drug, glimepiride on tablet. For this purpose, a calibration set for the drug was quantified using a partial least-squares regression method with a high-performance liquid chromatography (HPLC) as the reference method. The correlation coefficient (R2) between the NIRS method and the HPLC method in the...

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 API mass fraction or all three tablet...

Abstract Excipients represent diverse classes of molecules, small molecules or macromolecules, with versatile structures within a given class and are from natural, semi-synthetic and synthetic sources. They are essential ingredients in drug products independently of the route of administration where both traditional and non-traditional uses are present. Beyond their traditional use as formulation and manufacturing aids, certain excipients exhibit biological effects and thus can be used either...
