Irinox
Irinox (brand name Camptosar®) is a type of chemotherapy medication used in the treatment of cancer. It is a derivative of camptothecin, a natural alkaloid found in the Cinnamoni species of plants. Irinox works by interfering with the ability of certain cancer cells to divide and multiply. It is used in combination with other medications to treat several types of cancers, including colorectal, lung, and ovarian.
Uses for Irinox
Irinox is commonly used for the treatment of colon cancer (colon carcinoma), which may be advanced or metastatic. It can also be used to treat other cancers, such as small cell and non-small cell lung cancer, stomach cancer, ovarian cancer, and pancreatic cancer.
Mechanism of Action
Irinox works by interfering with the function of essential enzymes in the body, such as topoisomerase I. These enzymes are necessary for DNA synthesis and repair, and they are found in cancer cells at higher levels than in normal cells. By blocking this enzyme, Irinox prevents cancer cells from replicating and causes them to die off naturally.
How Long Does It Take to Work?
Irinox usually takes one to two weeks to begin working in the body. For some patients, it may take longer for the medication to take effect and start reducing tumor size. Treatment plan and timetable will be determined by the doctor.
Absorption
Irinox is rapidly and completely absorbed from the gastrointestinal tract. The plasma concentration peaks 1-2 hours after administration.

How does Irinox work?
Irinox works by interfering with the cells' ability to divide. The drug works on the enzyme topoisomerase, which is responsible for enabling a cancer cell to reproduce, thus stopping the cancer cell's ability to make copies of itself.
In what form is Irinox given?
Irinox is typically given intravenously (via a drip) as an infusion over several hours. It can also be given in a pill form to be taken by mouth.
What are the side effects of Irinox?
The most common side effects of Irinox include hair loss, nausea and vomiting, and diarrhea. Other side effects may include increased risk of infection, fatigue, and mouth sores. The drug may also cause liver damage, as well as blood clotting and bleeding problems, especially in those over 60 years old.
How long should I expect to take Irinox for?
Your doctor will determine the length of time you should take Irinox, as this will vary depending on the type of cancer being treated and your individual response to the medication. Generally, courses of Irinox may last anywhere from 3-6 months.
What should I do if I miss a dose of Irinox?
If you miss a scheduled dose of Irinox, contact your doctor or nurse immediately. Do not take a double dose to make up for a missed one, as this could be harmful.

If you experience any severe side effects from Irinox, such as abnormal bleeding or bruising, fever, severe diarrhea, severe nausea or vomiting, yellowing of the skin or eyes, dark urine, or any other serious side effects, contact your doctor or nurse immediately.
How often should I be monitored while on Irinox?
Your doctor may order periodic tests to check your liver, kidney, and blood counts while you are taking Irinox. These tests will help your doctor monitor any changes in your health while you are undergoing treatment.
Who should not take Irinox?
Irinox should not be taken by those who are pregnant, breastfeeding, or have an allergy to the drug or any of its ingredients. It is also important to discuss any existing liver, kidney, or heart conditions with your doctor before taking Irinox.
Is Irinox covered by insurance?
Irinox is covered by most insurance plans, but it is important to check with your insurer in advance to determine your coverage and cost. In some cases, depending on the prescription, you may be responsible for a portion of the cost.
What is the difference between Irinox and other chemotherapy drugs?
Irinox works by interfering with the enzyme topoisomerase, which is responsible for enabling a cancer cell to reproduce. Other chemotherapy drugs may work differently, by targeting different enzymes or pathways in the cancer cell.
What other treatments can be used in addition to Irinox?
Depending on the type of cancer being treated, your doctor may recommend additional treatments in addition to Irinox. For instance, radiation therapy, immunotherapy and targeted drug treatments may be used in combination with chemotherapy, or as a stand-alone treatment.
Is there any dietary restrictions with Irinox?
Your doctor may recommend avoiding certain foods while taking Irinox. Be sure to follow your doctor's instructions, as eating certain foods can interfere with the drug's effectiveness. Additionally, drinking alcohol should be avoided while taking Irinox.

Is Irinox a targeted therapy?
No, Irinox is not a targeted therapy, but rather a chemotherapy drug. Targeted therapies work to target specific pathways or mutations within a cancer cell, whereas chemotherapy works to attack all rapidly dividing cells, both cancerous and noncancerous.
Can Irinox be used to treat other types of cancer?
Yes, Irinox is approved to treat several different types of cancer, including colorectal cancer, small cell lung cancer, and head and neck cancers. However, its use in other types of cancer will depend on your individual situation and must be assessed by a medical professional.
