    Aim: The aim of the present investigation was to carry out the in vitro and in vivo studies of the cocrystals of a poorly soluble BCS Class II drug aceclofenac with two selected cocrystal formers, i.e., gallic acid and nicotinamide and hence to improve its solubility and bioavailability. Materials and Methods: The in vitro dissolution studies of the cocrystals which were formed by solvent evaporation method in the stoichiometric ratio of 1:1 after screening were carried out in pH 1.2 buffer solution using Shimadzu 1201 UV-Visible spectrophotometer. The in vivo bioavailability studies were carried out on adult male New Zealand albino rabbits following a parallel design. The blood samples were analyzed using high-performance liquid chromatography. The various pharmacokinetic parameters such as Cmax, Tmax, and area under the curve for the two cocrystals were calculated. Conclusion: Both the cocrystals showed a better dissolution profile than the pure drug and the physical mixture of the pure drug and the cocrystals former in the in vitro dissolution studies. The oral bioavailability also showed a significant increase of 1.77 and 1.37 times when compared to that of pure aceclofenac (P < 0.05).
