All the new forms were characterised using multiple techniques, PXRD, SC-XRD, DSC, and FTIR. The stability of the forms was studied, and, for the more stable forms, i.e., (lidhcl) forms, the solubility was determined through FTIR analysis. The new crystalline forms obtained with (lidhcl) and the three coformers showed an interesting steric stabilisation mechanism of the oxidation of hydroxybenzenes and showed good physicochemical properties with respect to (lidhcl), constituting a mechanism of modulation of the physicochemical properties.}, organization = {Spanish Agencia Estatal de Investigacion of the Ministerio de Ciencia, Innovacion, y Universidades (MICIU) - FEDER, UE PGC2018102047-B-I00 B-FQM-478-UGR20}, publisher = {MDPI}, keywords = {Lidocaine}, keywords = {Cocrystals}, keywords = {Mechanochemistry}, keywords = {Multicomponent materials}, keywords = {API}, keywords = {Pharmaceutical solids}, keywords = {Solubility}, title = {Lidocaine Pharmaceutical Multicomponent Forms: A Story about the Role of Chloride Ions on Their Stability}, doi = {10.3390/cryst12060798}, author = {Verdugo Escamilla, Cristóbal and Alarcón Payer, Carolina and Acebedo Martínez, Francisco Javier and Fernández Penas, Raquel and Domínguez Martín, Alicia and Choquesillo Lazarte, Duane}, }
