International Journal of Pharmacy Research & Technology (IJPRT) https://ijprt.org/index.php/pub <p><strong>International Journal of Pharmacy Research &amp; Technology (IJPRT) </strong>an International Journal of Pharmaceutical Research &amp; Technology <strong>(ISSN - 2250–0944) (P-ISSN 2250-1150)</strong> (An official publication of <em>Advanced Scientific Research</em>) is established in the year 2009. </p> <p>The aim of the ​<strong>International Journal of Pharmacy Research &amp; Technology (IJPRT) </strong>is to become an effective medium for inspiring the researchers to bring out their contributions in the form of research papers, articles, case studies, review articles and in the fields of Pharmacy, Medical sciences and Science and technology. The dissemination would thus help the industries, professional organisations to adopt and apply the information for creating new knowledge and enterprise. The publication would also help in enhancing awareness about the need to become research minded.</p> <p>All articles published in the journal will be freely available to scientific researchers to all over the globe. We will be making sincere efforts to promote our journal across the world in various ways. It is hoped that this journal will act as a common platform for researchers to pursue their objectives.</p> IJPRT en-US International Journal of Pharmacy Research & Technology (IJPRT) 2250-1150 Amorphous –state Characterization and Dissolution Behaviour of Efavirenz- Tocopheryl Polyethylene Glycol Succinate (TPGS)-1000 Solid Dispersions https://ijprt.org/index.php/pub/article/view/243 <p>The aim of the present investigation was to enhance the aqueous solubility and dissolution rate of a poorly soluble drug, efavirenz, by preparation of solid dispersions with tocopheryl polyethylene glycol succinate (TPGS)-1000, a non - ionic surfactant. Phase solubility studies suggested that the solubility of efavirenz increased with the increase in TPGS concentration.1 absorption. Gibbs free energy (ΔG) were negative, indicatingthe spontaneous nature of efavirenz solubilization. Dispersions in different ratios were prepared using the fusion method and their physicochemical characteristics were investigated using Fourier Transform Infrared Spectroscopy(FTIR), X-ray Powder Diffraction studies(XRPD) and Scanning Electron Microscopy(SEM).A drug: carrier ratio of 1:1.5 w/w prepared by cooling the fused mixtures at 5° C showed the highest drug release of 33.27%.It was demonstrated that decrease in crystallinity of the drug and H-bonding between efavirenz and TPGS-1000 might be responsible for the enhanced dissolution rate. Analysis of dissolution data showed the best fitting with Higuchi model.</p> JASMINE KAUR RANDHAWA RABIA DHILLON NEENA BEDI Copyright (c) 2024 International Journal of Pharmacy Research & Technology (IJPRT) https://creativecommons.org/licenses/by-nc/4.0 2024-04-08 2024-04-08 14 2 1 12
