In tacrolimus group 1 were sub therapeutic range that is also female. In cyclosporine group also 1(female) patient under the therapeutic range. In toxic levels, tacrolimus group were having 7 patients all that patients are males. In cyclosporine group only 1 patient was above therapeutic range. In conclusion this study reveals the wide interpatient variation of blood and plasma drug levels and the usefulness of carrying out therapeutic drug monitoring of Tacrolimus, cyclosporine and of Phenytoin and valproic acid in renal transplant and epileptic patients respectively.
