WebA natural water soluble protocatechuic acid and L-theanine cocrystal composition is described. The cocrystal composition may be created by a method including solvent-assisted mechanical grinding. The natural water soluble cocrystal composition is suitable for sublingual administration, preferably to humans. Web摘要： A novel method to convert S‐ and racemic (RS‐) ibuprofen (Ibu) into an oily state at ambient temperature (25°C) was developed. Using menthol and aqueous isopropanol (IPA) as melting point depressing agents, the two‐phase melt systems (TMSs) of Ibu consisting of a homogeneous oily phase and a homogeneous aqueous phase were obtained.
