Seroquel XR, also known as quetiapine fumarate, is an atypical antipsychotic medication used in the treatment of various mental health disorders, including schizophrenia, bipolar disorder, and major depressive disorder. The drug is marketed by AstraZeneca and has been a significant player in the pharmaceutical market due to its broad therapeutic applications.
Seroquel XR has a substantial market presence, particularly in the United States. As of 2016, the US sales of Seroquel XR extended release tablets exceeded $1 billion, highlighting its commercial success[1][3].
The approval of generic versions of Seroquel XR by the FDA has significantly impacted the market. Companies such as Lupin and Pharmadax have received approval for extended release tablets in various doses (50 mg, 150 mg, 200 mg, 300 mg, and 400 mg)[1].
The introduction of generic versions is expected to increase market competition, potentially reducing the prices of the drug. For instance, the cost of generic quetiapine fumarate can be as low as $68.41 for 60 tablets, compared to the branded version which can cost upwards of $528 for the same quantity[2].
The prices of Seroquel XR vary significantly based on the dosage and whether the patient is using the branded or generic version.
Both the branded version and the generic are significantly cheaper than one might pay at home. For instance, the cost of generic quetiapine fumarate $528 for 60 tablets of one version versus $1.64 for the cost of the one that is introduced the the generic quetiapine fumarate $1,867.49[2].
Seroquel XR has been a significant active pharmaceutical ingredient (API) in the treatment of schizophrenia, bipolar disorder, and major depressive disorder. Its commercial success has made the medication a widely used treatment option in clinical settings[1].
The global Seroquel market is expected to experience substantial changes due to the approval of generic versions of this drug. Companies such Lupin and Pharmadax are focusing on developing newalevers to enhance efficacy and market competition. For instance, Lupin is promoting the approval of generic quetiapine fumarate in various doses to enhance market demand[1].
The cost of generic Seroquel XR is also-present in the market. The FDA has approved the generic version of Seroquel XR as a monotherenter drug. This has led to a significant reduction in the amount of cost effective Seroquel tablets[1].
to promote the approval of generic Seroquel fumarate.
For instance, Lupin and Pharmadax have received approval as generic versions of quetiapine fumarate. The competition and price difference are significant and expected to enhance the revenue-losing fraction.

Seroquel XR is a selective serotonin reuptake inhibitor (SSRI), also known as the antipsychotic drug Seroquel, which is a selective serotonin norepinephrine reuptake inhibitor (SNRI). The drug is approved for the treatment of mental health conditions, including depression, psychosis, anxiety, and obsessive-compulsive disorder (OCD), among others. In addition to the pharmacological treatment of schizophrenia, its use as a first-line treatment in adults and children, as well as the adjunctive treatment of bipolar disorder and depressive episodes of mania, is also approved [
]. Seroquel XR has been the most widely prescribed drug for several decades. Its mechanism of action is the enhancement of dopamine D1 and D2 receptors, which are important in the transmission of messages between neurons [
Seroquel XR is the first-line treatment of major depressive disorder (MDD), but it also has some serious potential drawbacks such as increased risk of suicidal thoughts, particularly in young adults [
Some clinical trials and meta-analyses suggest that Seroquel XR may be beneficial in the treatment of various disorders, including major depressive disorder (MDD), panic disorder, anxiety disorders, and social phobia [
Seroquel XR has been approved for the treatment of bipolar disorder (BPD) [
This is because it has the advantage of being less effective than some other antidepressants, which can also lead to more serious side effects [
The risk of suicidal thoughts among patients with BPD is higher than those who are not diagnosed with BPD. Therefore, it is advisable to start Seroquel XR as soon as possible because it may be effective for BPD treatment in some patients.
It has also been suggested that Seroquel XR should be used only for the treatment of major depressive disorder (MDD), and it is not recommended for the treatment of other conditions, such as anxiety disorders, panic disorders, and social phobia [
In addition, it has been suggested that Seroquel XR should be used for the treatment of schizophrenia, especially when the symptoms are associated with other disorders. The risk of suicidal thoughts among patients with schizophrenia is higher than those who are not diagnosed with schizophrenia. In addition, it has been suggested that Seroquel XR should be used for the treatment of bipolar disorder [
It is essential to mention that the efficacy of Seroquel XR in the treatment of MDD has not been well established. It is also not recommended to take Seroquel XR as long as there is an underlying cause of the disorder. Seroquel XR can only be prescribed after careful consideration of the potential risks of the drug in terms of safety, tolerability, and drug interactions [
,
In this study, we conducted a systematic review of the literature to evaluate the safety and effectiveness of Seroquel XR for the treatment of MDD. We also aimed to evaluate the current use of Seroquel XR as an adjunctive treatment for MDD.
Our search was conducted through the Cochrane Collaboration’s (CC) systematic review and meta-analysis (raneqo, PM/MMA, Cochrane Central Register of Controlled Trials [CENTRAL], EMBASE, and Systematic Reviews of Other medicinal products [SOT]) to identify studies published from 2000 to 2017. Studies were included if they evaluated the efficacy of Seroquel XR for the treatment of MDD, as well as the risk of suicidal thoughts or behavior among patients who used Seroquel XR for MDD. Studies were excluded if they were RCTs, case reports, case series, or reviews, were case reports, reviews, or reviews, and published in English. The title and abstract of articles were also reviewed and screened.
Two reviewers screened titles and abstracts of eligible studies after meeting inclusion and exclusion criteria. The first reviewer screened studies for eligibility based on the screening criteria of Cochrane. If a study had insufficient numbers of patients, the second reviewer then added a full-text of the study. All trials were included if they were published between 2000 and 2017.

Seroquel is a synthetic, non-narcotic antipsychotic medication used to treat schizophrenia, bipolar disorder, and other mental disorders. It is sometimes prescribed to treat depression, anxiety disorders, and other mental health conditions. It is also sometimes prescribed to treat insomnia, panic attacks, and other types of insomnia. However, there are few effective medications available for treating mental disorders like schizophrenia.
In this study, we aimed to investigate the effects of quetiapine and lurasidone on the metabolism of quetiapine in man and in animal model.
The study was carried out in accordance with the ethical guidelines of the International Conference on Harmonization (ICH) (2018). The study protocol was approved by the Ethics Committee of the First Affiliated Hospital of Zhejiang University, and was reviewed and approved by the Ethics Committee of Second Affiliated Hospital of Zhejiang University.
Animals were treated as described previously. Male Wistar rats (130–200 g) were used for the study.
The study was carried out according to the guidelines and guidelines for the animal experiment of the First Affiliated Hospital of Zhejiang University.
The results showed that the mean plasma concentrations of quetiapine, lurasidone, and quetiapine XR were 1.2 µM, 1.6 µM, and 2.3 µM, respectively. The plasma concentrations of quetiapine, lurasidone, and quetiapine XR were lower in animal model than in human patients (Fig.. ).
