Penfluridol is a long acting oral antipsychotic agent taken once a week for the treatment of schizophrenia and other psychotic disorders. Weekly dosage regimen of the drug makes it an ideal drug in non-compliant patients, which is commonly seen in 50-75% of psychotic disorder patients. Better compliance may be associated with less relapses, better quality of life, less crises and less or shorter hospitalizations, leading to lower costs.
