Product Description & Overview

Ifosfamide is an injection chemotherapy drug that is given through a vein. It is a white crystalline powder dissolved in a liquid solution before it is given. Ifosfamide is a class of drug known as an alkylating agent. It works by creating damage to the DNA in cancer cells, halting their growth and causing them to die. Ifosfamide is like another drug called cyclophosphamide, but has unique characteristics and side effects. It is only given by skilled healthcare providers, most often in a hospital or approved cancer treatment center.

Therapeutic Indications

Ifosfamide is used to treat different cancers. It is approved for the treatment of testicular cancer, especially when the other treatments do not work. It is also very commonly used for soft tissue sarcomas, lung cancer, cervical cancer, ovarian cancer, and certain types of lymphoma. 

Doctors also use it to treat bone cancer and bladder cancer. It is not usually given alone but with other chemotherapy drugs to achieve better outcomes. Whether to utilize ifosfamide depends on the stage and type of cancer, the health of the patient, and the success of other therapies.

Mechanism of Action

Ifosfamide does not work directly when it is given in the body. It first passes through the liver, where enzymes break it down into active forms. These active chemicals bind to DNA in cancer cells, creating cross-links between the strands of DNA. This stops the cancer cells from reproducing their DNA and dividing, killing them. One of the chemicals produced can harm normal bladder tissue, so another drug called means is administered to protect the bladder during treatment. The mechanism by which ifosfamide acts makes it effective against fast-growing cancer cells.

Clinical Benefits

Ifosfamide can be of immense value in the treatment of resistant cancers to first-line drugs. It is one of the intense combination drugs that can lead to full healing of testicular cancer in some patients.

Side Effects

Common

The majority of patients taking ifosfamide will experience side effects. Hair loss is very common and will usually occur in all parts of the body. Nausea and vomiting are also common but can be reduced with medication. Fatigue, loss of appetite, and altered taste are common, too. Counts of blood cells usually fall, causing infection, bleeding, or anemia. Patients also notice hematuria (blood in their urine) when the bladder is inflamed. People become confused or sleepy while receiving treatment, which is usually a sign of a reversible effect on the brain known as encephalopathy.

Serious / Rare

Some side effects are more dangerous and need prompt medical attention. A severe but uncommon effect is brain toxicity, which can produce hallucinations, seizures, or coma. Kidney injury is a possibility, particularly if the patient is a child or has existing kidney disease. The bladder may become inflamed and hemorrhage, and can produce pain or hematuria. This is why means and hydration are essential during administration. There can also be the possibility of serious infections due to low white blood cells. Occasionally, long-term therapy can lead to heart problems or secondary cancers, such as leukemia.

Drug Interactions

Ifosfamide has the potential to interact with a wide range of drugs. Some drugs can increase how rapidly it is metabolized by the liver, which will make it more toxic or less effective.

Others may delay its degradation, leading to higher concentrations in the body. It should not be used it in combination with other medications that damage the kidneys since this may increase the risk of acquiring kidney failure.

Live vaccines must be kept off during treatment since the immune system is weakened.

Certain antibiotics, antifungal medicines, and anti-seizure medications will interact with how ifosfamide functions. Always tell your doctor about all the medicines and supplements you use.

Dosage & Administration

Ifosfamide is injected intravenously, usually for 30 minutes or longer. The usual adult dose is approximately 1.2 grams per square meter of body surface area daily, given for five consecutive days. The cycle may be repeated every three weeks.

The dose is modified according to the kidney function of the patient, blood test results, and drug tolerance. Ifosfamide is always co-administered with means to avoid damage to the bladder.

The patients take fluids a lot, or IV fluids are administered to prevent bladder injury. Before and throughout treatment, blood tests are done to make sure everything is safe.

Contraindications

Ifosfamide should not be given to those allergic to it or its components. It should also not be given to those with urinary tract obstructions or severe bladder disease. It should be avoided in patients with very low blood cell counts unless treatment is totally necessary. It is not safe for pregnant women to take because it could hurt the baby. Patients with active infection, severe kidney disease, or persistent disorders of the brain may also be asked to avoid this drug or use it with extreme care.

Precautions & Warnings

Ifosfamide is a strong medicine and needs to be monitored closely. Regular monitoring of blood counts is needed to detect declines in white blood cells, red blood cells, and platelets. Doctors may delay or reduce the dose in case of low counts. 

Safety Advice

Patients taking ifosfamide must be closely monitored at home or in the outpatient clinic. Regular monitoring of blood, kidney, and liver function is required. Mensa should always be given with the drug, and there should be hydration.

Patients must avoid being around sick people since infection is possible. They should report to healthcare providers any fever, pain on urination, mood changes, or breathlessness.

Women must avoid pregnancy during this drug and for several months afterward. Men should not become fathers during treatment and should bank sperm prior to therapy.

Special Instructions

It is crucial that follow-up visits be made during ifosfamide treatment. The patient must take all medications precisely as instructed, including means and any anti-nausea medicines.

Proper daily intake of fluids protects the bladder. Patients should avoid alcohol, tobacco, and certain foods like grapefruit, as they have an influence on the drug.

Any confusion, bleeding, or severe tiredness should be reported to a nurse or career immediately.

Patients may be warned against driving or operating machinery if they are drowsy and confused. Maintaining a treatment diary may help track side effects and reactions.

Lifestyle & Dietary Advice

Extra fluids are suggested with treatment with ifosfamide unless otherwise advised. Small amounts of food eaten frequently may help with nausea and lack of appetite.

Avoid greasy or spicy foods to prevent upsetting the stomach. Avoid alcohol and grapefruit juice. Rest and minimal exercise can improve general well-being. Good hygiene, including hand washing regularly, minimizes the risk of infection.

If baldness bothers them, patients can wear a wig or scarf. Fertility will be affected, so patients must discuss such options as freezing eggs or sperm before treatment.

Comparison with Similar Cytotoxics

Ifosfamide resembles cyclophosphamide in that both are in the same class of drugs and function similarly.
