| 520 | |a Purpose Pharmaceutically active compounds (API) in solid form have several disadvantages which may include polymorphism, poor solubility, and low bioavailability. To overcome these issues, API-based ionic liquids have been proposed to solve this problem. Methods Solvent evaporation method was selected to prepare ionic liquid forms of CVD. A binary mixture of CVD with citric acid, tartaric acid, and saccharin in 1:1 M ratio was dissolved in 5 ml of methanol then they left 4 days for solvent evaporation. The solubility of CVD and prepared ionic liquids were measured in different media. Results A viscous yellow liquid in all cases was obtained. More than three-unit differences between $ pK_{a} $ of CVD and studied compounds and characterization by different instrumental analysis methods confirmed the formation of an ionic liquid form of CVD and the prepared ionic liquids could significantly change the solubility of CVD. Conclusion Overall, ionic liquids of CVD could be used for overcoming the disadvantages of its solid form and increasing CVD solubility. However, pH, type, and concentration of dissolution medium and the solubility of counter-ions are critical issues which they should be considered in evaluating solubility of CVD and its ionic liquid forms. | ||

To overcome these issues, API-based ionic liquids have been proposed to solve this problem. Methods Solvent evaporation method was selected to prepare ionic liquid forms of CVD. A binary mixture of CVD with citric acid, tartaric acid, and saccharin in 1:1 M ratio was dissolved in 5 ml of methanol then they left 4 days for solvent evaporation. The solubility of CVD and prepared ionic liquids were measured in different media. Results A viscous yellow liquid in all cases was obtained. More than three-unit differences between $ pK_{a} $ of CVD and studied compounds and characterization by different instrumental analysis methods confirmed the formation of an ionic liquid form of CVD and the prepared ionic liquids could significantly change the solubility of CVD. Conclusion Overall, ionic liquids of CVD could be used for overcoming the disadvantages of its solid form and increasing CVD solubility.

To overcome these issues, API-based ionic liquids have been proposed to solve this problem. Methods Solvent evaporation method was selected to prepare ionic liquid forms of CVD. A binary mixture of CVD with citric acid, tartaric acid, and saccharin in 1:1 M ratio was dissolved in 5 ml of methanol then they left 4 days for solvent evaporation. The solubility of CVD and prepared ionic liquids were measured in different media. Results A viscous yellow liquid in all cases was obtained. More than three-unit differences between $ pK_{a} $ of CVD and studied compounds and characterization by different instrumental analysis methods confirmed the formation of an ionic liquid form of CVD and the prepared ionic liquids could significantly change the solubility of CVD. Conclusion Overall, ionic liquids of CVD could be used for overcoming the disadvantages of its solid form and increasing CVD solubility. However, pH, type, and concentration of dissolution medium and the solubility of counter-ions are critical issues which they should be considered in evaluating solubility of CVD and its ionic liquid forms.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Carvedilol</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ionic liquid</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Solubility</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shayanfar, Ali</subfield><subfield code="0">(orcid)0000-0001-7507-9057</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of pharmaceutical innovation</subfield><subfield code="d">New York, NY : Springer, 2006</subfield><subfield code="g">14(2018), 4 vom: 12.

Ionic Liquid Forms of Carvedilol: Preparation, Characterization, and Solubility Studies |
| abstract |
Purpose Pharmaceutically active compounds (API) in solid form have several disadvantages which may include polymorphism, poor solubility, and low bioavailability. To overcome these issues, API-based ionic liquids have been proposed to solve this problem. Methods Solvent evaporation method was selected to prepare ionic liquid forms of CVD. A binary mixture of CVD with citric acid, tartaric acid, and saccharin in 1:1 M ratio was dissolved in 5 ml of methanol then they left 4 days for solvent evaporation. The solubility of CVD and prepared ionic liquids were measured in different media. Results A viscous yellow liquid in all cases was obtained. More than three-unit differences between $ pK_{a} $ of CVD and studied compounds and characterization by different instrumental analysis methods confirmed the formation of an ionic liquid form of CVD and the prepared ionic liquids could significantly change the solubility of CVD. Conclusion Overall, ionic liquids of CVD could be used for overcoming the disadvantages of its solid form and increasing CVD solubility. However, pH, type, and concentration of dissolution medium and the solubility of counter-ions are critical issues which they should be considered in evaluating solubility of CVD and its ionic liquid forms. © Springer Science+Business Media, LLC, part of Springer Nature 2018 |
