Bilt salt effect on cocrystal dissolution
WebAug 30, 2013 · If the solubility of the cocrystal is higher than the solubility of the API, and the coformer and the API dissociates completely in solution (that is, no solubilising effect), dissolution will lead to an API concentration that exceeds the solubility of the API and therefore a supersaturated solution as regards the API. WebSep 26, 2015 · Salt formation is a common approach to enhance drug solubility, but it is not successful when the active pharmaceutical ingredient (API) does not contain ionizable functional groups in its chemical structure. ... 4-ASA cocrystals with different polymorphic forms and crystal habits to investigate the effect on dissolution, wettability, flow and ...

Websaturation and drug, cocrystal, and coformer dissolve. Region IV: solution is supersaturated with respect to cocrystal, and drug can convert to cocrystal. Crystallization pathway involves: (1) solution saturated with respect to coformer (the most soluble component in this example), (2) dissolution of drug, and (3) cocrystal formation. WebAn Etodolac Glutaric acid cocrystal significantly increases in solubility with a dissolution rate 2 – 3 times faster than that of pure etodolac. The enhancement of aqueous solubility and dissolution rate of etodolac with co-crystallization may be a potential way to solving the bioavailability problem of etodolac.
WebFeb 3, 2016 · Similar to salt formation, cocrystallization can increase both solubility and dissolution rate of drugs. 8 The overall effect of a coformer on cocrystal solubility depends on both the solvation energies of the cocrystallizing components and the cocrystal lattice energy. 12 As a result, a soluble coformer can promote cocrystal dissolution … WebAug 30, 2013 · Salt and cocrystal formation are the most commonly used method of increasing solubility and dissolution rate of pharmaceutical compounds, and are of …
