Characterization of solid state forms of glipizide

In the present study various crystalline forms of glipizide were prepared in order to enhance dissolution rate of glipizide and to evaluate the stability of developed forms. Four different strategies have been followed to prepare crystalline forms of glipizide – a. crystallization from the methanolic solution of the drug under pH control b. crystallization by vapor diffusion c. crystallization by antisolvent precipitation technique and, d....
