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.
Ibrance (palbociclib) is a medication designed to combat certain types of breast cancer. Developed by Pfizer, it has been approved by the Food and Drug Administration (FDA) for the treatment of hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer in combination with specific hormonal therapies.
This innovative drug falls under the category of kinase inhibitors, which work by interfering with the processes that cancer cells use to grow and divide. Ibrance targets cyclin-dependent kinases 4 and 6 (CDK 4/6), proteins that are crucial for cancer cell proliferation. By inhibiting these proteins, Ibrance slows down the progression of cancer, offering hope and extended survival for patients battling advanced breast cancer.
Before you buy Ibrance, it is crucial that you talk to your healthcare provider about potential side effects and Ibrance cost.
