Tacrolimus is approximately how many times more potent than cyclosporine?

Explanation:
Both drugs are calcineurin inhibitors used to prevent organ rejection, but tacrolimus is far more potent. This comes from how they interact with their binding proteins: tacrolimus forms a complex with FKBP12 that inhibits calcineurin more effectively than the cyclosporine–cyclophilin complex. Because of this stronger inhibition, much smaller amounts of tacrolimus are needed to achieve the same immunosuppressive effect—about a hundredfold less in dosing. Clinically, this is reflected by tacrolimus requiring roughly 1/100th the dose of cyclosporine to reach similar levels of immunosuppression, though exact numbers vary with assays and patient factors.
