The FDA has approved asenapine (Secuado, Noven Pharmaceuticals) for the treatment of adult patients suffering from schizophrenia.
Asenapine is an atypical antipsychotic drug, (dopamine receptor antagonist that may also antagonize norepinephrine and serotonin (5-HT) receptors, according to the CMS), administered via a once-daily transdermal system patch.
“As people living with schizophrenia cycle through treatments their therapeutic options narrow, leaving them and their caregivers looking for new treatment options,” said Leslie Citrome, MD, MPH, clinical professor of psychiatry and behavioral sciences, New York Medical College in a statement. “In addition to offering a new delivery option, transdermal patches can also provide caretakers and healthcare providers with a non-intrusive, visual confirmation that a treatment is being utilized.”
