Drug/metabolite profiles after iv
drug administration (cont'd).

b - Drug total body clearance

Examine the drug and metabolite conc-time profiles after administration of the same dose of drugs that have different total body clearance (Other parameters are similar).

Detailed conclusion

Higher drug clearance results in faster rate of metabolite formation. The total amount of metabolite formed does not change since fm is constant.
