Solubility Enhancement Techniques: A Review Sharma Neha*, Bharkatiya Meenakshi Bhupal Nobels’ Girls’ College of Pharmacy, Udaipur, Rajasthan, India, 313002 Solubility is one of the important parameter to achieve desired concentration of drugs in systemic circulation for pharmacological response to be shown. Solid dispersion is one of the best approaches for solubility enhancement. endobj In 1961, Sekiguchi and Obi 5 developed a practical method whereby many of the limitations with the bioavailability enhancement of poorly water soluble drugs can be overcome. In quantitative terms it is concentration of dissolved solute in a saturated solution at a specific temperature. /FontBBox [-568 -216 2046 693] ;�ྟ�x�������Z��O@���ޮzۄ毃��~�P�*�|���6o�3�Ls� ���лi��N��'m�������~�/a��)=f�k�P�O� 2TherdosePharmaPvt.Ltd,Kukatpally,Hyderabad,AndhraPradesh, India %���� endobj Q_�Zc��w�D���_'�j��IrDJg����4�y�Y����lĠ[籃[ľ'�X-���h�z�/a��h)�� ��7 |@��ʨi��D1N@�JP^��� �T�h�H�C���w��J�(�!Vq�Yӯ��DvL]�)u�t'��֎j�����(�O��y������OO%��ెǹ�ߕ�'9ϙV���V'9;ҏ���z-�A�ܿ�-���S ou���z�� J�o�^>� /BaseFont /Times#20New#20Roman I.
