Prograf (Tacrolimus) is used for the prevention of rejection of transplanted organs.

Drug Name

Prograf (Tacrolimus)

Drug Uses

Prograf is used for the prevention of rejection of transplanted organs.

How Taken

Oral Prograf is taken twice daily. Doses vary widely and are based on blood tests that measure the amount of Prograf in the body. Taking Prograf with food can reduce some of the abdominal pain that can occur with this medicine; however, food can reduce the amount of Prograf that is absorbed. This is especially true with fatty foods. Thus, Prograf is best taken without food. If it must be taken with food, it should be taken with non-fatty food.

Drug Class and Mechanism

Prograf is a drug that suppresses the immune system and is used to prevent rejection of transplanted organs. Prograf accomplishes its immune-suppressing effecting by inhibiting an enzyme (calcineurin) crucial for the multiplication of T-cells, cells that are vital to the immune process. The use of oral Prograf allows transplantation specialists to reduce the dose of steroids which are also used to prevent rejection. This "steroid-sparing effect" is important because of the many side effects that can occur when larger doses of steroids are used for a long period of time. Prograf was approved by the FDA in April, 1994 for liver transplantation and also has been used in patients for heart, kidney, small bowel, and bone marrow transplantation.
