Flufenamic acid cocrystal

WebMost of the examples cited in the literature are of cocrystals formed between an API and a coformer chosen from the generally recognized as safe (GRAS) substance list; however few examples exist where a cocrystal consists of two or more APIs. These cocrystals are commonly known as multi API, multi-drug or drug- drug cocrystals. WebApr 6, 2024 · The formation of cocrystals and salt can be predicted by a study of the transfer of protons and is determined by the ∆pKa = [pKa (base) − pKa (acid)]. A pKa value difference of greater than 2 or 3 between the API and coformer symbolizes the transfer of proton between acid and base.

Web1.1.1 The p K a-based tool. The use of the p K a rule to predict cocrystal formation is based on the fact that a cocrystal can be distinguished from a salt by whether a proton transfer has occurred from an acid to a base. The p K a describes the tendency of an acid, or a conjugate acid of a base, to give up a proton. It has been suggested that a Δp K a [p K a … WebInsight into Flufenamic Acid Cocrystal Dissolution in the Presence of a Polymer in Solution: from Single Crystal to Powder Dissolution Minshan Guo,† Ke Wang,† Ning …
