Primary Outcome Measures:
  • To identify the clinical profile of the patients administered Ziprasidone for schizophrenia [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To determine the severity of schizophrenia , among the study population [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • To determine the daily dosage and formulation of Ziprasidone that is being used [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • To determine how treatment satisfaction is rated by the patient using theTreatment Satisfaction Questionnaire for Medication (TSQM) [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • To determine body weight development seen during treatment with Ziprasidone [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  • To determine if treatment with Ziprasidone had to be stopped prematurely [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • To determine the frequency of previously diagnosed (before the visit) metabolic risk factors in schizophrenic patients [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • To determine how the overall efficacy and tolerability of Ziprasidone is rated by the physician [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  • To determine what the change in the severity of the condition as well as clinical improvement of symptoms is rated using global assessments by the physician [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • To determine whether treatment decision with Ziprasidone was made on the basis of metabolic risk factors of the patient [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
