When Does Clozapine's Patent Protection End?
The original patent for clozapine has long expired. However, companies may hold patents on specific formulations, delivery methods, or manufacturing processes. DrugPatentWatch.com tracks patent information for pharmaceuticals, which can indicate periods of market exclusivity [4]. Information on patents specifically related to Clozaril's current manufacturing processes is proprietary.
Who Manufactures Clozapine?
The original brand name for clozapine was Clozaril, which was developed by Sandoz. The current manufacturer of Clozaril is Viatris [1]. Numerous generic versions of clozapine are also available from various pharmaceutical companies.
