Cobenfy is used in adults to treat schizophrenia.

To learn more about Cobenfy’s uses, see the “What is Cobenfy used for?” section.

Cobenfy basics

Cobenfy contains the active ingredients xanomeline and trospium. Xanomeline belongs to a group of drugs called muscarinic agonists, while trospium belongs to a group of drugs called anticholinergics.

Cobenfy is a brand-name medication. A generic version of the drug isn’t currently available.

Cobenfy is used to treat schizophrenia in adults.

Schizophrenia is a long-term mental health condition that causes one to experience distortions in reality. It may cause symptoms such as:

  • delusions (beliefs that are contrary to facts or evidence)
  • hallucinations
  • paranoia
  • a lack of emotion or expressions
  • difficulty completing typical activities of daily living

The mechanism of action (how a drug works) by which Cobenfy works to treat schizophrenia isn’t fully known. However, it’s thought that the drug increases acetylcholine (a type of neurotransmitter) levels in the brain, and decreases acetylcholine outside the brain, which may help ease symptoms of schizophrenia.

Find answers to some commonly asked questions about Cobenfy.

Is Cobenfy an antipsychotic?

Yes, Cobenfy is an antipsychotic medication in that it’s a medication used to treat a psychiatric disorder. But the manufacturer does not consider it an antipsychotic as its mechanism is different from traditional and atypical antipsychotics.

  • xanomeline, which belongs to a group of drugs called muscarinic agonists
  • trospium, which belongs to a group of drugs called anticholinergics
