Question 3

How does Rapamune work?

Accepted Answer

Mechanism of Action

Rapamune belongs to a class of drugs known as immunosuppressants. Its primary function is to lower the body's natural defense system (the immune system) to prevent it from reacting to foreign tissues or abnormal cell growth.

Preventing Organ Rejection

When a person receives a kidney transplant, their immune system may recognize the new organ as a foreign invader. To protect the body, the immune system produces white blood cells that attack and try to destroy the new kidney. Rapamune works by blocking a specific protein in the body called mTOR (mammalian target of rapamycin).

By inhibiting this protein, the medication prevents certain immune cells, such as T-cells and B-cells, from growing and multiplying. This reduces the immune system's ability to attack the transplanted organ, helping the body accept the new kidney.

Treating Lung Disease

In patients with lymphangioleiomyomatosis (LAM), a rare lung disease, Rapamune works by targeting the same mTOR protein. In this condition, abnormal cells grow uncontrollably in the lungs. By blocking the mTOR pathway, the medication helps slow down the growth and spread of these cells, which can help preserve lung function.

Accepted Answer

Administration Instructions

Rapamune is taken by mouth, usually once a day at the same time. It is available as a tablet or an oral solution. It is important to follow your healthcare provider's instructions exactly regarding when and how to take this medication.

Consistency with Food

You may take Rapamune with or without food, but you must be consistent. Choose one method and take every dose the same way. Changing how you take it in relation to meals can change the amount of medicine that enters your bloodstream.

Using the Oral Tablet

Tablets should be swallowed whole. Do not crush, chew, or break the tablets, as this can affect how the medication is absorbed.

Using the Oral Solution

The liquid solution requires special handling and preparation:

Use the provided oral syringe to measure the dose.

Mix the solution with water or orange juice in a glass or plastic cup. Do not use other liquids, such as grapefruit juice, for mixing.

Drink the mixture immediately. To ensure you get the full dose, add a small amount of additional liquid to the same cup, swirl it gently, and drink that as well.

Missed Dose

If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and return to your regular schedule. Do not take extra medicine to make up for a missed dose.

If you become pregnant or think you might be pregnant while taking this medication, contact your healthcare provider immediately to discuss the potential risks.

Breastfeeding
