Quetiapine fumarate medication

Quetiapine is a generic pharmaceutical product used primarily to treat schizophrenia, bipolar disorder, and major depressive disorder. Because it is an 'off-patent' drug, it is manufactured by numerous pharmaceutical companies globally including AstraZeneca, Teva, Sandoz, and Mylan.

Originally developed by researchers at AstraZeneca in the United Kingdom under the brand name Seroquel, the formulation is now produced in various facilities across Europe, India, North America, and China to meet global demand. Ownership and manufacturing site depend entirely on the specific pharmaceutical laboratory listed on the secondary packaging.
