The stаndаrd оrаl dоsing regimen оf metronidazole for the treatment of intra-abdominal infections in adults is 500 mg every 6 hours. In the general adult population, metronidazole has an elimination half-life (t1/2) of 2.5 hours and an apparent total clearance (CL/F) of 20.8 L/h. (20 pts. total) a. Using the standard oral metronidazole regimen of 500 mg every 6 hours in the general adult population, calculate: (i) Maximum steady state concentration (3 pts.) (ii) Minimum steady state concentration (1 pt.). b. Patient C.Y., who has an intra-abdominal infection, has been receiving metronidazole 400 mg orally every 6 hours for several days. At steady state, the measured trough plasma concentration (Css,min) was 4.78 mg/L. Assuming that the apparent volume of distribution (V/F) in Patient C.Y. is the same as the average value in the general adult population, calculate the elimination rate constant (k) of metronidazole in Patient C.Y. (3 pts.) c. Design a practical oral dosing regimen (i.e., the dose and dosing interval) for Patient C.Y. that will achieve the same therapeutic exposure as the standard 500 mg every 6 hours regimen in the general adult population. (10 pts.) d. Is a loading dose needed for Patient C.Y.? If yes, calculate the loading dose. (3 pts.)
