99% Tacrolimus API Of GMP Factory


Tacrolimus monohydrate, also known as FK-506, is a white crystalline powder.

Existing as an anhydrous or monohydrate form, it is soluble in many solvents such as ethanol, methanol, acetone, and chloroform but insoluble in water.

It was first extracted as an antibiotic from soil actinomycetes in Japan in 1984.

Later, tacrolimus is found to be very effective in reducing the patient’s immune system activity and the risk of organ rejection after an organ transplant.
