"The researchers followed 83 people recently diagnosed with schizophrenia for a one-year period. Half were given the daily oral form of risperidone and the others were given the long-acting injectable form. All interventions were given as part of the UCLA Aftercare Research Program.
"The researchers found that patients taking the injectable medicine were much more likely to stick with their treatment than patients taking the oral form, and that the injectable did a better job of controlling psychotic symptoms. During the 12-month period, just 5 percent of those taking the injectable medication had their psychotic symptoms return, versus 33 percent of those taking the pill.
“In addition, Subotnik said, the benefits appear to be greater than when given after individuals have had the disorder for many years, which indicates that the long-acting injectable should be offered to patients earlier in the course of schizophrenia.”
