Introduction to Cytosor (Cytarabine) 100mg 

Cytosar-U (Cytarabine) 100mg is a widely used prescription chemotherapy medicine indicated for the treatment of certain blood cancers, particularly leukemia. It belongs to a class of oncology drugs known as antimetabolites, which work by interfering with DNA synthesis and preventing cancer cell growth.

Cytosor® (Cytarabine) 100mg is classified under Prescription Medicines, Oncology Medicines, Anticancer Drugs, and Injectable Cancer Therapies. It contains Cytarabine, a cytotoxic agent that targets rapidly dividing cancer cells.

The original brand of Cytarabine is Cytosar-U, while Cytosor® is a generic brand offering similar therapeutic benefits when prescribed by a qualified healthcare professional.

What Is Cytosar-U (Cytarabine) 100mg? 

Cytosar-U is the original brand name for Cytarabine, an injectable chemotherapy medication primarily used in the treatment of hematologic malignancies.

Cytarabine belongs to a group of medicines known as Antimetabolite Antineoplastic Agents. These drugs disrupt DNA replication, thereby preventing cancer cells from multiplying.

Generic versions such as Cytosor® 100mg contain the same active compound and are used based on physician recommendation and availability.

Drug Class and Mechanism of Action 

Cytarabine is classified as an antimetabolite chemotherapy agent with potent antineoplastic activity.

How Cytarabine Works 

It works through the following mechanisms:

• Inhibits DNA synthesis during the S-phase of the cell cycle
• Incorporates into DNA and RNA, causing faulty genetic material
• Prevents cancer cell replication and survival

These effects help control the spread of cancer cells.

How Cytosor Works in the Body 

Cytarabine targets rapidly dividing cells, particularly in the bone marrow, where leukemia cells are produced.

Key Actions of Cytarabine 

• Blocks DNA formation in cancer cells
• Stops cell division and proliferation
• Promotes cancer cell death

Generic versions like Cytosor® provide effective treatment outcomes when administered under medical supervision.
