What is Avastin?

Avastin is a drug brand that provides cures for both cancer and retinal problems. It sells bevacizumab, and mostly this medication is known by its brand name, Avastin.

Bevacizumab boosts immunity during cancer treatments as it is made up of immunity cells. Avastin produces or boosts the growth of antiangiogenic agents present in the body.

While treating tumours, Avastin works on tumour growth cells and stops their further growth by terminating those blood vessels, which helps the tumour grow by providing sufficient oxygen.

This drug is a whole antibody type of vitamin and nutrient to it and targets vascular growth factor A in the human body. It relaxes the muscles and boosts energy.

Avastin, when compared to Lucentis, is less expensive. But the total expenses depend on the type of disease a patient has.

What is Lucentis?

Lucentis mainly treats all types of eye-related infections and diseases. Mainly ranibizumab is known in the markets by its brand names Lucentis and Byooviz.

It is a fab fragment type of drug that builds the growth of antigens in the body. Antigens are substances or molecules that help the immune system.

To develop antibodies against foreign invaders that can make the immune system weak. The source of this drug is humanized, which means it is made up of non-human species.

Genentech was the first biotechnology corporation to make this drug, first marketed in the United States of America. It treats both age-related as well as diabetic.

Retinal issues like diabetic retinopathy, vision loss, macular degeneration, blurred vision, etc. Lucentis’s main work is to terminate the growth of new abnormal cells or blood vessels.

Present in the eye that may lead to leakage in the eye. This drug is injected into the eye directly.
