AstraZeneca is the current manufacturer of the brand-name drug Seroquel [1]. Seroquel is an atypical antipsychotic used to treat schizophrenia, bipolar disorder, and major depressive disorder [2].
Who Else Markets Seroquel?
Beyond AstraZeneca, Seroquel is also manufactured and marketed by various generic drug companies [3]. These generic versions contain the same active ingredient, quetiapine fumarate, but may differ in inactive ingredients [3].
When Did Seroquel Lose Patent Protection?
The primary patents protecting Seroquel have expired, allowing for the market entry of generic versions. For the immediate-release formulation, patent protection largely ended around 2010 [4]. Extended-release formulations also faced patent expirations in subsequent years [4]. Information on specific patent expiry dates and related legal challenges can be found on DrugPatentWatch.com [4].
How Does Seroquel Compare to Other Antipsychotics?
Seroquel is an atypical antipsychotic, a class that differs from older typical antipsychotics in its mechanism of action and side effect profile [5]. Atypical antipsychotics, including Seroquel, generally have a lower risk of movement disorders but may carry a higher risk of metabolic side effects such as weight gain and diabetes [5]. Other commonly prescribed atypical antipsychotics include Risperdal, Zyprexa, and Abilify [6].
What are the Common Side Effects of Seroquel?
Common side effects reported for Seroquel include drowsiness, dizziness, dry mouth, constipation, weight gain, and blurred vision [2]. More serious side effects can include changes in heart rhythm, high blood sugar, and involuntary movements [2]. Patients considering Seroquel should discuss potential risks and benefits with their healthcare provider [2].
What is the Dosage for Seroquel?
Dosages for Seroquel vary depending on the condition being treated and the patient's individual response [2]. The drug is available in immediate-release and extended-release tablet forms [2]. Dosing typically starts low and is gradually increased [2].
