Top Generic choice
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.
Prezista (Darunavir) is a medication prescribed for the treatment of HIV-1 infection in adults. HIV-1 is the virus responsible for causing AIDS (Acquired Immune Deficiency Syndrome). To enhance the effectiveness of Prezista medication, it needs to be taken alongside specific medications like cobicistat and ritonavir, which help increase its levels in the body. However, it's important to note that darunavir does not provide a cure for HIV infection.
When considering treatment options for HIV-1 infection, it's important to consider factors such as effectiveness, potential side effects, and the Prezista cost.
HIV is a virus that attacks the immune system, while AIDS is the advanced stage of HIV infection. HIV weakens the immune system, making individuals more susceptible to infections and diseases. With proper medical care and treatment, people with HIV can live long and healthy lives without developing AIDS.
