Sufentanil

Sufentanil

Sufentanil is used for the treatment of serious fungal infections and used to prevent invasive fungal infections in people who have had a bone marrow transplant. 

 A fungus is a germ that ranges from something tiny and barely visible to something big like a mushroom. They are all around us and don’t usually cause any problems. However, rarely, they can settle down and grow in places where they shouldn’t. Places on our bodies like our nails, skin, between our toes and, in women, the vaginal area. This can happen even in fairly healthy people. Fungal infections are common throughout much of the natural world. In humans, this type of infection happened when an invading fungus takes over an area of the body and is too much for the immune system to handle. The symptoms of fungal infection will depend on the type, but common symptoms include the following:

  • Skin changes (red and possibly cracking or peeling skin)
  • Itching 

Bone marrow is the spongy tissue inside some of the bones in the body. It contains immature cells called stem cells. Healthy bone marrow and blood cells are needed to live. When the disease affects bone marrow so that it can no longer function effectively, a marrow or cord blood transplant could be the best treatment option. For some patients, it is the only potential cure. 

A bone marrow transplant is also called a stem cell transplant. It is a procedure that infuses healthy blood-forming stem cells into your body. It is to replace your damaged or diseased bone marrow. You might need a bone marrow transplant if your bone marrow stops working and does not produce enough healthy blood cells. A bone marrow transplant may be used to:

  • Provide new stem cells which can help kill cancer cells directly
  • Replace diseased or damaged marrow with new stem cells
  • Safely let the treatment of your condition with high doses of chemotherapy or radiation by replacing or rescuing the bone marrow damaged by treatment 

Sufentanil is a type of medicine called a triazole antifungal. This helps treats the infections caused by fungi. The Food and Drug Administration (FDA) has already approved this medication. Sufentanil comes as a sublingual tablet for oral use. Each tablet of Sufentanil is available in the dosage strength of 30 mg. 

How does Sufentanil work?

Sufentanil works by preventing fungi from making a substance called ergosterol. It is a component of fungal cell membranes.

The cell membranes of fungi are vital for their survival. They keep unwanted substances from entering the cells and stop the contents of the cells from leaking out. Without ergosterol as part of the cell membrane, the membrane is weakened or damaged and essential constituents of the fungal cells can leak out. This kills the fungi and hence clears up the infections.

Sufentanil is usually reserved as a treatment for progressive infections in people whose immune systems are underactive. It may be due to AIDS, cancer treatment, or following an organ transplant. Serious fungal infections can sometimes be life-threatening in these groups of patients.

How to use Sufentanil?

The dosage is based on your medical condition and response to the treatment. Sufentanil is to be taken by mouth usually twice a day, every 12 hours. It is important to take the medicine regularly for the best benefit. Take each dose at the same time and in the same way each day.

Sufentanil is to be taken at least an hour before or an hour after a meal. 

If you forget to take a dose just take your next dose when it is due. Do not take a double dose to make up for a missed dose. You must take this medication exactly as it is given by your doctor. Even if you feel better, do not suddenly stop this medication until your doctor tells you to do so. Stopping it suddenly may increase the chance that the infection will come back and that the fungi will grow resistant to the medicine. Some people may need to take Sufentanil for a long time. It is particularly those hard to treat infections or bone marrow transplant recipients taking this to prevent infections. Follow carefully the instructions of your doctor.
