EXXUA (gepirone)** Reviews
EXXUA (gepirone), developed by Fabre-Kramer Pharmaceuticals, is a first-of-its-kind oral selective 5HT1A receptor agonist approved by the US Food and Drug Administration (FDA) for Major Depressive Disorder (MDD) in adults. This new class of antidepressants aims to modulate serotonin activity in theCentral Nervous System (CNS) through selective agonist activity at 5-HT1A receptors.
Background and History
Launched in 1986 as an immediate-release formulation, gepirone was later reformulated into an extended-release (ER) tablet meant for once-daily administration. Despite several attempts to secure FDA approval, including a failed resubmission, gepirone eventually received the nod in September 2023 after a significant number of negative and positive clinical trials.
Mechanism of Action
Gepirone's mechanism of action is thought to involve the activation of 5-HT1A receptors, which are found pre- and postsynaptically in the brain. This results in an increase in serotonin neurotransmission, potentially providing benefits for mood and behavioral symptoms in individuals with depression.
Pharmacokinetics
The extended-release formulation of gepirone enables a slower and more sustained release of the medication into the bloodstream, reducing the need for Frequent dosing and potentially minimizing adverse event rates.
Efficacy and Side Effects
Two clinical studies showed that people with depression who took gepirone experienced greater improvement in their Hamilton Depression Rating Scale (HAM-D) scores compared to those taking placebo. While sexual side effects were common, they were reported at comparable rates to placebo and did not necessitate discontinuation of treatment.
Side Effects Reported in clinical trials:
- Dizziness (49%)
- Nausea (35%)
- Headache (31%)
- Feeling sleepy or tired (15%)
- Trouble sleeping (14%)
- Diarrhea (10%)
Warnings and Contraindications
There are several importantWarnings and Contraindications associated with gepirone:
- Suicidal Thoughts and Actions: Antidepressant medications, including gepirone, may increase suicidal thoughts and actions in some people, particularly young adults within the first few months of treatment or when the dose is changed. Patients should be closely monitored for signs of suicidal behavior.
- QT Prolongation: Gepirone can causeQT prolongation, a change in heart rhythm that can lead to life-threatening arrhythmias. The risk is highest in patients with existing heart rhythm problems, family history of long QT syndrome, and certain medications known to prolong the QT interval.
- Serotonin Syndrome: Taking gepirone with certain other medications can increase the risk of developing serotonin syndrome, a potentially life-threatening condition characterized by rapid heart rate, fever, and muscle stiffness.
- Bipolar Disorder: people with bipolar disorder should avoid taking gepirone as it may trigger manic episodes, although it is not approved for use in individuals with this condition.
- Kidney or Liver Impairment: The starting dosage of gepirone may need to be adjusted in patients with severe renal or liver impairment.
Patient Advocacy and Support
Many patient advocacy groups and mental health organizations have embraced gepirone as a potentially valuable treatment option for individuals affected by depression. They emphasize the importance of research and development to provide new and effective treatments for unmet needs.
