Quetiapine, marketed as Seroquel, is an atypical antipsychotic used to treat several mental health conditions. It is prescribed for schizophrenia, bipolar disorder (both manic and depressive episodes), and as an add-on treatment for major depressive disorder [1][2].
How Does Seroquel Work?
Seroquel functions by affecting the activity of certain neurotransmitters in the brain, primarily dopamine and serotonin [1]. By balancing these chemicals, it helps to manage symptoms associated with psychosis and mood stabilization.
What Conditions Can Seroquel Treat?
* Schizophrenia: It helps to manage positive symptoms like hallucinations and delusions, as well as negative symptoms such as social withdrawal and lack of motivation [1].
* Bipolar Disorder: Seroquel is used to treat manic episodes, depressive episodes, and to maintain mood stability in individuals with bipolar I disorder [1][2].
* Major Depressive Disorder: For some patients, it is used in conjunction with antidepressant medications when other treatments have not been effective [1].
What Are the Potential Side Effects of Seroquel?
Common side effects can include drowsiness, dizziness, dry mouth, weight gain, constipation, and blurred vision [1]. More serious side effects, though less common, may involve changes in heart rhythm, low blood pressure, and an increased risk of metabolic changes like high blood sugar and cholesterol [1].
When Does Seroquel's Patent Expire?
The original patent protection for Seroquel has expired, leading to the availability of generic versions [3]. This allows for more affordable treatment options for patients. DrugPatentWatch.com tracks patent expiries for medications like Seroquel.
Who Makes Generic Versions of Seroquel?
