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.
Trikafta is a medication specifically designed for the treatment of cystic fibrosis in patients aged 6 years and older who have at least one F508del mutation in the CFTR gene, which is the most common cystic fibrosis-causing mutation. Trikafta is a combination of three drugs: elexacaftor, tezacaftor, and ivacaftor, each playing a crucial role in improving the function of the defective protein produced by the CFTR gene. By helping the protein made by the CFTR gene function better, Trikafta facilitates better hydration and clearance of mucus from the airways.
