Hydroxyurea Capsules 500 mg are a specialized pharmaceutical formulation utilized primarily in the treatment of specific oncological conditions, namely head and neck cancers, and hematological disorders such as sickle cell anemia. Its mode of action in cancer therapy involves the inhibition of ribonucleotide reductase, an enzyme crucial for DNA synthesis, thereby restricting the proliferation of malignant cells. In the context of sickle cell disease, Hydroxyurea elevates fetal hemoglobin (HbF) production in red blood cells, which normalizes their shape and enhances circulatory function, mitigating the severity and frequency of sickle cell crises. This medication is integral to targeted treatment regimens and requires careful medical supervision during administration to manage dosage and monitor therapeutic effects.

Hydroxyurea increases fetal hemoglobin (HbF) levels in red blood cells, which helps normalize their shape, improving blood flow and reducing painful sickle cell episodes.
It inhibits ribonucleotide reductase, an enzyme critical in DNA synthesis, thereby preventing cancer cells from growing and multiplying.
No, Hydroxyurea 500 mg capsules are prescription-only and must be used under medical supervision.
They should be stored in a cool, dry place away from direct sunlight to maintain stability and effectiveness.
Hydroxyurea is primarily indicated for these uses; any other application should be determined by a qualified healthcare provider.
Uses of Hydroxyurea Capsules 500 mg:
Hydroxyurea is used in the treatment of head and neck cancer and sickle cell anemia.
How Hydroxyurea works
In cancer, Hydroxyurea works by blocking an enzyme (ribonucleotide reductase) which is required for synthesis of DNA. This prevents the cancer cells from growing and multiplying. In sickle cell disease, it works by increasing fetal haemoglobin (HbF) levels in red blood cells (RBCs). This helps the RBCs assume a normal shape, improves blood flow and protects against complications such as painful sickle cell episodes.
