Processes for preparing quetiapine and salts thereof
The present invention provides herein a two-step process for preparing pharmaceutically pure quetiapine and salts thereof by obtaining the starting material 11-chloro-dibenzo-thiazepine followed by reacting the 11-chloro-dibenzo-thiazepine with 1-(2-hydroxyethoxy)ethylpiperazine, or its salt, in the presence of an inorganic or organic base in an organic solvent or in a two-phase solvent system. The present invention provides also a novel, one-pot reaction process for preparing pharmaceutically pure quetiapine and salts thereof. The two processes provided herein can be easily, conveniently and inexpensively scaled-up.

Use of phosphodiesterase 5 (PDE5) inhibitors in the treatment of schizophrenia
The use of phosphodiesterase 5 (PDE5) inhibitors for treatment of schizophrenia is described. Suitable PDE5 inhibitors for use for treatment of schizophrenia include sildenafil, vardenafil, tadalafil, E-8010, zaprinast, and E-4021. In one embodiment, for example, a method is described for treating schizophrenia in a patient which comprises treating the patient with an effective amount of a PDE5 inhibitor, or a pharmaceutically acceptable salt, solvate, or composition thereof. The PDE5 inhibitor may be administered orally. The PDE5 inhibitor may also be administered together with one or more conventional antipsychotic medications such as risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole, clozapine, haloperidol, and fluphenazine.
