In the case of perfusion rate-limited distribution, which of the following changes is most likely to reduce the rate of drug entry into tissues?

When distribution equilibrium has been reached and active transport does not contribute to drug distribution, increasing plasma protein binding will result in an increase in:

Patient W.L. received a 20 mg intravenous (IV) bolus dose of pamidronate for the treatment of Paget’s disease of bone. Plasma samples were collected 15 minutes and 5 hours after administration. The measured plasma concentrations were: C15min = 76.6 µg/L, C5h = 68.1 µg/L. Assume that pamidronate follows a one-compartment pharmacokinetic model with first-order elimination. (17 pts. total) a. To improve therapeutic response, the physician decides to administer pamidronate by continuous IV infusion and wishes to achieve a target steady-state plasma concentration (Css) of 200 µg/L. Calculate the IV infusion rate required to achieve the desired steady-state concentration in this patient. (9 pts.) b. Calculate the plasma concentration of pamidronate 4 hours after the IV infusion is initiated. (2 pts.) c. One month later, Patient W.L. returns for a second treatment course. Due to a severe intra-abdominal infection, his renal function has declined, and his creatinine clearance (CrCL) has decreased from 110 mL/min to 65 mL/min. Assume that 46% of an IV dose of pamidronate is excreted unchanged in urine. To maintain the target Css of 200 µg/L, calculate the following: (i) IV infusion rate (4 pts.); (ii) Loading dose (2 pts.).

For a given drug, which of the following statements regarding mean residence time (MRT) is correct?
