Ribeiro, Laura S. S.; Falcão, Amílcar C.; Patrício, João A. B.; Ferreira, Domingos C.; Veiga, Francisco J. B.In the present work, to maintain a suitable blood level of vinpocetine (VP) for a long period of time, VP-cyclodextrin-tartaric acid multicomponent complexes were prepared and formulated in hydroxypropylmethylcellulose matrix tablets. In vitro and in vivo performances of these formulations were investigated over a VP immediate release dosage form. Solubility studies were performed to evaluate the drug pH solubi...
