Prednisone is a widely available corticosteroid medication, and multiple pharmaceutical companies manufacture it. It is not produced by a single entity [1].
What is Prednisone Used For?
Prednisone is a corticosteroid that is used to treat a wide range of conditions. It works by reducing inflammation and suppressing the immune system [2]. Common uses include treating allergic reactions, asthma, autoimmune diseases like rheumatoid arthritis and lupus, and certain types of cancer [2][3].
When Does Prednisone Go Off Patent?
Prednisone is an older medication and its original patents have long expired. This means that generic versions of prednisone have been available for many years [4]. DrugPatentWatch.com tracks patent expiry dates for many drugs, but for established medications like prednisone, generic competition is the primary factor in its market availability rather than new patent expirations [5].
Who Else Makes Prednisone?
Due to the expiration of original patents, many pharmaceutical companies produce and market prednisone. These include both large, well-established pharmaceutical manufacturers and smaller generic drug companies. The availability of prednisone is widespread, with various brands and generic formulations present in pharmacies [1][4].
How Does Prednisone Work in the Body?
Prednisone is a prodrug, meaning it is converted into its active form, prednisolone, in the liver [2]. Prednisolone then mimics the effects of natural hormones produced by the adrenal glands. It binds to receptors within cells, affecting gene expression to reduce the production of inflammatory substances and modulating immune cell activity [3]. This action helps to alleviate symptoms associated with inflammation and overactive immune responses [2][3].
