MustargenGeneric Name: Mechlorethamine
Trade name: Mustargen®
Other names: Nitrogen Mustard, Mustine, Mechlorethamine Hydrochloride
Drug type: Mechlorethamine is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. Mechlorethamine is classified as an "alkylating agent." (For more detail, see "How this drug works" section below).
What Mechlorethamine is used for:
Note: If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful.
How Mechlorethamine is given:
Side effects of Mechlorethamine:
Important things to remember about the side effects of Mechlorethamine:
The following side effects are common (occurring in greater than 30%) for patients taking Mechlorethamine:
These side effects are less common side effects (occurring in about 10-29%) of patients receiving Mechlorethamine:
Delayed effects of Mechlorethamine:
Not all side effects are listed above. Some that are rare (occurring in less than 10% of patients) are not listed here. However, you should always inform your health care provider if you experience any unusual symptoms.
When to contact your doctor or health care provider:Contact your health care provider immediately, day or night, if you should experience any of the following symptoms:
The following symptoms require medical attention, but are not an emergency. Contact your health care provider within 24 hours of noticing any of the following:
Always inform your health care provider if you experience any unusual symptoms.
Monitoring and testing:
You will be checked regularly by your health care professional while you are taking mechlorethamine, to monitor side effects and check your response to therapy. Periodic blood work to monitor your complete blood count (CBC) as well as the function of other organs (such as your kidneys and liver) will also be ordered by your doctor.
How Mechlorethamine works:
Cancerous tumors are characterized by cell division, which is no longer controlled as it is in normal tissue. "Normal" cells stop dividing when they come into contact with like cells, a mechanism known as contact inhibition. Cancerous cells lose this ability. Cancer cells no longer have the normal checks and balances in place that control and limit cell division. The process of cell division, whether normal or cancerous cells, is through the cell cycle. The cell cycle goes from the resting phase, through active growing phases, and then to mitosis (division).
The ability of chemotherapy to kill cancer cells depends on its ability to halt cell division. Usually, the drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division. If the cells are unable to divide, they die. The faster the cells are dividing, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce cell suicide (self-death or apoptosis).
Chemotherapy drugs that affect cells only when they are dividing are called cell-cycle specific. Chemotherapy drugs that affect cells when they are at rest are called cell-cycle non-specific. The scheduling of chemotherapy is set based on the type of cells, rate at which they divide, and the time at which a given drug is likely to be effective. This is why chemotherapy is typically given in cycles.
Chemotherapy is most effective at killing cells that are rapidly dividing. Unfortunately, chemotherapy does not know the difference between the cancerous cells and the normal cells. The "normal" cells will grow back and be healthy but in the meantime, side effects occur. The "normal" cells most commonly affected by chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea, and/or hair loss. Different drugs may affect different parts of the body.
Mechlorethamine is classified as an alkylating agent. Alkylating agents are most active in the resting phase of the cell. These drugs are cell cycle non-specific. There are several types of alkylating agents.
