According to clinical trials, Cobenfy significantly reduced the severity of schizophrenia symptoms in adults within five weeks. **How does Cobenfy make you feel?** The medication can alleviate positive symptoms like hallucinations and delusions, while also addressing negative symptoms such as emotional flatness or lack of motivation.

For decades, negative symptoms in schizophrenia have been notoriously difficult to treat, with traditional antipsychotics primarily targeting positive symptoms. A major development in this field is the FDA approval of Cobenfy (KarXT) in 2024, raising the question: what is the new antipsychotic for negative symptoms and how does it work differently?.

Derived from the South American plant genus *Pilocarpus*, pilocarpine has been used to treat glaucoma for over 100 years. It is a direct-acting cholinergic agonist used to increase secretions and promote smooth muscle contraction. So, what is the mechanism of action of pilocarpine? It primarily stimulates muscarinic receptors within the parasympathetic nervous system.

An estimated 4.2 million Americans have glaucoma, a condition where the medication pilocarpine can be used to help manage eye pressure. Understanding **how does pilocarpine cause miosis**, or pupil constriction, is key to understanding its therapeutic effect.

Cevimeline, known by the brand name Evoxac®, was approved for use in the United States in 2000. A prescription cholinergic agonist, it is primarily used to address the symptoms of dry mouth (xerostomia) in adults with Sjögren’s syndrome.

In clinical trials, certain levels of pilocarpine administration were considered potentially dangerous, highlighting that while a prescribed usage is generally safe, excessive amounts can cause toxicity. The potential for toxicity depends heavily on the amount used, route of administration, and individual patient factors.

Yes, pilocarpine is a direct-acting muscarinic agonist, mimicking the effects of the neurotransmitter acetylcholine. It has been a mainstay in ophthalmology for over a century, and its mechanism involves direct stimulation of muscarinic acetylcholine receptors throughout the body.

In September 2024, the FDA approved the first new class of antipsychotic medications in decades, containing the active muscarinic agonist **xanomeline**. This oral medication, marketed as Cobenfy, represents a significant paradigm shift by targeting cholinergic receptors to treat schizophrenia in adults.

Affecting about 1% of the population, schizophrenia has been treated largely with dopamine-targeting medications for decades. The recent FDA approval of **COBENFY**, a new schizophrenia drug, marks a significant shift with its novel, non-dopamine mechanism of action. This first-in-class muscarinic agonist represents a new pharmacological approach to managing schizophrenia symptoms in adults.
