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?

16. Suppose that the allergy drug, Sneezebgone, has a half life of 12 hours and is excreted at a rate that is proportional to the amount present. At 8am, Declan takes one 10 mg dose of Sneezebgone, and then another 10mg dose at 8pm. Assuming that the drug is given intravenously via injection and mixed into his bloodstream immediately) how many mg of sneezebgone are in his system at midnight?

5. The drug Xanax has a half-life of 11.2 hours. A patient took a 3 mg dosc at 8 AM. (a) Find an exponential function which models the amount of Xanax in the person's system after t hours, where t= 0 represents 8 AM. (Hint: You may want to start by figuring out two data points for this function.) (b) Approximately when will the patient have less than 0.1 mg of Xanax left in their systein? (Use your graphing technology...

2. Steady State concentration 3 hours after last dose A patient receives a 1000 mg dose of an antibiotic every 6 hours by repetitive IV injection (ouch!). The drug has a Vo of 20 L and an elimination half-life of 3 hours. Ct (post ss) = xon-e-ke x e-kt

The antiarrhythmic drug procainamide has the following characteristics: Therapeutic window 4 - 8 mg/L, half-life 3 hours, and volume of distribution 2 L/Kg. A 65 Kg patient requires an infusion in order to attain the plasmatic concentration of 6 mg/L. Recommend a loading dose and constant rate infusion (K0) for this treatment

17. Life Science: drug dosage. A dose of a drug is injected into the body of a patient. The drug amount in the body decreases at a rate of 55% per hour, that is, dA =-0.55A, dt where A is the amount in the body and r is the time, in hours. (a) A dose of 7 cubic centimeters (cc) is administered. Assuming A = 7. find the function that satisfies the equation. (b) How much of the initial dose...

A certain drug is eliminated from the bloodstream exponentially with a half-life of 24 hours. Suppose that a patient receives an initial dose of 15 milligrams of the drug at midnight. a) How much of the drug is in the patient's blood at noon the next day? b) Estimate when the drug concentration will reach 20% of its initial level.

A nurse is caring for a patient taking a drug that is metabolized in the liver. Additionally, the patient has been prescribed to receive two drugs that are both excreted from the same sites in the kidney. (Learning Objectives 1, 3, 4, and 5) When the nurse is reviewing a drug to be given, the nurse notes that the drug is metabolized in the liver. What data can be gathered based on the nurse’s assessment of the patient? When considering...
