Objective: The primary focus of this research is to ascertain that these different generic drug products from national and multinational companies competing in the local market are equivalent in quality. Material and Methods: A comparative quality analysis was executed on national and multinational brands of glimepiride tablets obtained from local pharmacies of Hyderabad. A cumulative of 6 glimepiride brands were selected and internationally accepted in-vitro tests were carried out at Industrial pharmacy laboratory of Department of Pharmaceutics, Faculty of Pharmacy, University of Sindh, Jamshoro, during time period August 2021 to August 2022 to compare with Pharmacopoeia standards. Results: All the drug products (Glimepiride tablets) obtained from local market were meeting the standards laid by BP for tests of weight uniformity, diameter, thickness, hardness, friability, disintegration, and content uniformity/assay. Conclusion: Every generic of glimepiride tablets from various local and multinational manufacturers are pharmaceutical equivalents and can be prescribed interchangeably.

Objective: To formulate unmodified crystalline meloxicam solid dispersions by the use of surfactants and polymer. This polymeric particulate system is named as meloxicam-loaded surface attached solid dispersion (MSDs). Methodology: This experimental study was conducted at Lab of Physical and Industrial Pharmacy, Hanyang University, South Korea. The duration of this study was around seven months. The first phase of this study (optimization and fabrication) was completed within 3 months, while, solubility, dissolution and physicochemical characterization was completed in next 4 months. These surfaces attached solid dispersions were prepared by using spray drying technology. Moreover, HPMC and SLS were used as hydrophilic carriers. Various MSDs were prepared using carriers/drug, and were evaluated for aqueous solubility and dissolution studies. Results: Amongst different formulation prepared, MSDs3 having Meloxicam/HPMC/SLS in a (1:0.5:0.5) gave the highest solubility and dissolution (i.e. from 0.25 ±0.17ug/ml of meloxicam to 153 ±5.3ug/ml). Moreover, dissolution was enhanced from 2.96 ±0.55% to 47 ±1.07% at 15 minutes. Furthermore, physicochemical characterization was performed by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and powder X-ray diffraction (PXRD). Conclusion: In conclusion we can predict a better solubility and dissolution of meloxicam in surface attached solid dispersion.
