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.
The global Seroquel market is valued at several millionumers (MS) ( 2017) and growing. The market is driven by the increasing prevalence of disorders such as schizophrenia and bipolar disorder. Seroquel, a type of drug called a selective serotonin reuptake inhibitor, is used in clinical trials to enhance sexual function and treat depression.
The market is also growing. As of 2023, the market size was valued at $3.9 billion and is expected to reach $4.5 billion by 2031, growing at a Compound Annual Growth Rate (CAGR) of 4.2% from 2024 to 2031[4].
There is a lot to be expected in the coming years. The increase in buying power comes from product lines that are expanding and more people are seeking treatment. The increasing awareness and adoption by patients and healthcare providers are also contributing to the market's growth.
The increasing adoption of e-commerce and online shopping is another key factor.
The Seroquel market is dominated by several key players including drug manufacturer AstraZeneca, pharmaceutical company G& R Pharmaceutical, Cipla, Wafco, Vivus, Torrent, Aurobindo, Pfizer, SmithKline, Wafco, Takeda, Glenmark, Aurobindo, and Walmart.
In 2019, Elephrad Consultants (EPC) ( India ) generated the biggest revenues of its business as they were acquired from various manufacturers and are rising in popularity.
The market for antipsychotic medication is further driven by the increasing awareness and acceptance of antipsychotic medications. The increasing adoption of online shopping and buying power are key factors contributing to the market growth[1].
No new drug will be launched until 2020. However, the market is expected to remain at a CAGR of 4.0% and $4.2 billion from 2024 to 2031. The expiration date for Seroquel is will be early 2023 if the drug is approved.
The patent expiration for quetiapine is a global problem that affects the market dynamics. While patents expire, AstraZeneca can bring new drug to market without affecting the patent market.
However, the patent expiry is an option for many patients. In the coming months, manufacturers will launch their products at lower prices and could lower the price to 60% off the cost of the branded product.

In the realm of psychiatry, mental health remains a crucial aspect of overall well-being, and the management of anxiety disorders has significant implications for quality of life [1]. The prevalence of anxiety disorders has been estimated at 1.5-20.6%, and the global prevalence rate is expected to increase at a projected annual growth rate of 15.5% by 2032 [2,3]. These factors have led many patients to seek professional help and seek treatment [4]. The World Health Organization (WHO) estimates that approximately 990 million children (aged between 6 months and 12 years) in the United States are afflicted with anxiety disorder, affecting nearly 3% of the US population. Anxiety disorders are defined as disorders in which individuals exhibit excessive or consistent feelings of fear or anxiety, or they are perceived as having a more intense and persistent worry, avoidance, or avoidance response to the physical or emotional stimuli of an activity or experience [4].
The prevalence of anxiety disorders is highest in older individuals (aged 65 years and older), but there is no universally accepted definition. The World Health Organization (WHO) estimates that about 4 million patients in the US experience anxiety disorders, affecting 1% of the US population. The prevalence rate of anxiety disorders ranges from 0.3% to 4.2% per year, with estimates ranging from 0.9% to 2.9% per year for patients aged 6 to 18 years [4].
While the prevalence of anxiety disorders is well-documented, their impact is multifactorial [1,4,5], and treatment options may vary from one patient to another. Seroquel (quetiapine) has shown a favorable impact on anxiety disorders among children and adults alike [6]. In the USA, patients are prescribed the antipsychotic medication quetiapine (Seroquel), a well-tolerated and safe alternative for treatment of schizophrenia, as an add-on to antipsychotic medications [7]. Quetiapine is available in the US under the trade name of quetiapine extended-release tablets (Seroquel XR) and can be prescribed with or without food. The World Health Organization defines an "add-on" medication to be any medication that has been shown to improve symptoms of anxiety disorders in adults [8].
The effectiveness of quetiapine is supported by clinical trials that have demonstrated its effectiveness in the treatment of anxiety disorders. Quetiapine is a first-line treatment for schizophrenia, and its safety and efficacy have been established in several randomized clinical trials [9]. However, the evidence base for its use in anxiety disorders is limited and may be confounded by methodological limitations, including a lack of blinding to treatment assignment, potential confounding effects of medication adherence, and confounding effects of age and gender [9]. Furthermore, quetiapine may interact with other medications and may cause metabolic side effects [10].
A comprehensive review of clinical trials in anxiety disorders found that studies investigating the safety of quetiapine were limited in their quality. This lack of blinding may have contributed to the limited information available about this drug in the literature [11].
It has been suggested that quetiapine may affect dopamine, a neurotransmitter in the brain that plays a role in regulating mood, appetite, and anxiety. A recent meta-analysis of placebo-controlled studies of quetiapine demonstrated that patients taking quetiapine had greater reductions in sleep latency and sleep duration compared with patients on placebo [12]. This may be due to the pharmacological effect of quetiapine on dopamine and its metabolic effects on the central nervous system, possibly by increasing the release of norepinephrine, which has been hypothesized to contribute to improvements in anxiety symptoms in some patients [13].
In addition to its antidepressant and anxiolytic properties, quetiapine also has antidepressant and anxiolytic properties in a post-marketing phase, and some patients reported improved mood and behavior [14].
A recent review by Pernice and colleagues concluded that quetiapine is effective in the treatment of schizophrenia and that its use is associated with improvements in anxiety symptoms and outcomes [15]. However, a recent meta-analysis of placebo-controlled studies of quetiapine concluded that no significant differences were observed in placebo-controlled trials of quetiapine in the treatment of anxiety disorders [16].
The evidence base for the use of quetiapine is not universally accepted and varies considerably between studies. Some studies have reported a positive effect in terms of reduction in symptoms of anxiety, and others have reported negative effects [17].
