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?

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....

When 800 mg of a new drug under study is administered IV in normal volunteers, 800 mg are recovered unchanged in urine. The AUC obtained after IV injection is 400 mg.h/L and the half life is 8 hours. When 400 mg are orally administered in volunteers 350 mg of drug are recovered unchanged in urine. Calculate: K, Kr, Vd, and oral bioavailability (F). thats all the data i have
