Background and Date of Approval
Hydroxyurea is an anticancer medication containing the active ingredient as hydroxyurea. It is used to treat chronic myeloid leukemia (cancer of white blood cells) and polycythemia vera (cancer of red blood cells). The benefits of this medication include treating cancer by slowing down the growth and division of cancer cells and treating sickle cell anemia by reducing the frequency and severity of painful episodes and preventing organ damage. It treats cervical, ovarian, melanoma (skin cancer), and head and neck cancer. Cancer is a disorder in which cells multiply uncontrolled and abnormally. Hydroxyurea was first approved by the United States Food and Drug Administration (FDA) in 1967 for treating certain types of cancer, including chronic myelogenous leukemia and certain types of skin cancer. Over the years, its uses have expanded to include treating other conditions.
Mechanism of Action of undefined
In cancer, hydroxyurea works by slowing down the growth and division of cancer cells, which can help to shrink tumors and prevent the spread of cancer to other parts of the body. This can lead to a reduction in the size and number of tumors, which may improve symptoms and increase survival rates. In sickle cell anemia, this medication works by increasing the production of fetal hemoglobin, which can help to prevent the abnormal shaping of red blood cells. This can reduce the frequency and severity of painful episodes, prevent damage to organs, and improve the overall quality of life. It also reduces the need for blood transfusions and hospitalization. It prevents complications such as stroke, acute chest syndrome, and pulmonary hypertension.
Uses of undefined
Hydroxyurea is a medication that has been approved for the treatment of various medical conditions. These include ovarian cancer, polycythemia vera, chronic myeloid leukemia, cervical cancer, head and neck cancer, and sickle cell anemia.
