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. WebThe low aqueous solubility of Flufenamic acid (FFA), a Biopharmaceutics Classification System (BCS) II class drug, is a major challenge to overcome its low bioavailability. Poor solubility and... 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. the park west palm beach golf
