Jason W., a 60-kg patient is started on 80 mg of gentamicin every 6 hours given as 1-hour infusions. Answer the following questions.
a) If this patient is assumed to have an average V of 15 L and a normal gentamicin half-life (population) of 3 hours, what will be the peak plasma concentration at steady state ( ) (assume peak concentration is taken right at the end of infusion)?

14. Gentamicin is often given in IV-bolus doses of 100 mg every 8 hours to achieve an average steady-state plasmatic concentration of 5 mg/L. The total clearance is normally 5.4 L/h in a 70 Kg-body weight person. Gentamicin is entirely eliminated by glomerular filtration. Your patient, however, is found to have a creatinine clearance one-third of normal. Your initial dosage regimen for this patient would probably be: a. 20 mg every 8 hours b. 33 mg every 8 hours c....

1. A new drug was given in a single intravenous dose of 200 mg to an 80- kg adult male patient. The apparent VD is 0.8 L/kg, and the drug is eliminated by 1st order kinetics. Compute the initial drug plasma concentration. 2. A drug has an elimination half-life of 4 hours and follows first-order kinetics. If a single 600-mg dose is given to a patient by IV bolus, what percent of the dose is lost in 12 hours?

A 86.5 kg patient has just received a single 500 mg oral dose of an antibiotic. This antibiotic has a 90% oral bioavailability, 8.6 hour elimination half-life, and a 1.1 hour absorption half-life. The drug literature states that the population volume of distribution is 1.1 L/kg for this medication. A blood sample was collected at the maximum drug concentration and reported to be 5.916 mg/L. What is the patient-specific volume of distribution of this antibiotic in this...
