A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Opdivo (nivolumab) is a prescription medication in the class of drugs known as immune checkpoint inhibitors, specifically targeting the PD-1 (programmed death-1) receptor on T cells. Opdivo is designed to enhance the body's immune response against cancer cells by inhibiting the interaction between PD-1 and its ligands, PD-L1 and PD-L2. This action helps to prevent cancer cells from evading the immune system.
Opdivo is approved for the treatment of various types of cancer, including melanoma, lung cancer, renal cell carcinoma, head and neck cancers, Hodgkin lymphoma, and more, depending on the stage of the disease and prior treatments. It is available as an intravenous formulation, administered by healthcare professionals in a clinical setting.
Before you buy Opdivo, it is crucial that you talk to your healthcare provider about potential side effects and Opdivo cost.
