What is Aurobindo's Seroquel (quetiapine) version?
Aurobindo manufactures a generic version of Seroquel, the brand-name medication containing quetiapine fumarate [1]. Quetiapine is used to treat schizophrenia, bipolar disorder, and major depressive disorder [2].
How does Aurobindo's quetiapine differ from brand-name Seroquel?
As a generic medication, Aurobindo's quetiapine is required to be bioequivalent to the brand-name Seroquel [3]. This means it contains the same active ingredient, in the same dosage form and strength, and is absorbed into the bloodstream at the same rate and to the same extent [3]. The primary difference lies in the inactive ingredients, such as fillers, binders, and dyes, which can vary between generic and brand-name products [3].
When did Aurobindo's quetiapine become available?
The availability of generic quetiapine, including from Aurobindo, is linked to patent expirations of the original Seroquel. Drug patents typically last 20 years from the filing date [4]. However, various market exclusivities can extend the effective patent life. Generic versions generally become available once these patents and exclusivities expire, allowing other manufacturers to produce and market their own versions of the drug [4]. DrugPatentWatch.com tracks these patent and exclusivity timelines for many medications [5].
What is the cost of Aurobindo's quetiapine?
Generic medications like Aurobindo's quetiapine are generally less expensive than their brand-name counterparts due to increased competition in the market [3]. Pricing can vary based on pharmacy, insurance coverage, and available discounts.
Who else makes generic quetiapine?
Many pharmaceutical companies manufacture generic versions of quetiapine. These include, but are not limited to, Teva Pharmaceuticals, Mylan (now Viatris), and Accord Healthcare, among others [1]. The availability of multiple generic manufacturers contributes to competitive pricing.
What are the potential side effects of quetiapine?
Common side effects of quetiapine can include drowsiness, dizziness, dry mouth, constipation, weight gain, and changes in blood lipid levels [2]. More serious, though less common, side effects can include movement disorders, metabolic changes, and an increased risk of stroke in elderly patients with dementia-related psychosis [2].
Are there any legal challenges regarding quetiapine patents?
Patent litigation is common in the pharmaceutical industry. Companies often challenge existing patents to gain an earlier entry into the market with their generic versions [4]. The specifics of any ongoing or past patent challenges related to Seroquel or its active ingredient, quetiapine, would be detailed in legal and patent databases.
