Caffeine has a therapeutic index of approximately 100:1. If the ED50 for caffeine is 12 mg/kg, what is the LD50? In a typical dose-response curve graph, what is placed along the vertical, y-axis? Sheila weighs 55 kg (121 pounds). She starts her day off with a large cup of Starbucks coffee (330 mg caffeine). Every day she drinks at least three large cans of Monster energy drink, each containing 160 mg of caffeine. In the evening, she drinks two cups...

9. Drug A has an ED50 of 10 mg and an LD50 of 45 mg, while Drug B has an ED50 of 60 mg and an LD50 of 300 mg. Determine the therapeutic index (TI) for each drug. Which is safer? Why?
2. DRUG Q has an ED50 of 20m/kg in humans and the LD50 is 100mg/kg. DRUG Z has an ED50 of 10mg/kg, and the LD50 is 20mg/kg. Calculate the therapeutic index for both drugs (show all work!). Which drug would be easier for a person to overdose
A new drug will be on shelves soon, to help treat high blood pressure. In mice, this drug (DRUG A), has an LD50 of 25 mg/kg. However, DRUG A has some competition! DRUG B is also a new drug that will be released to help treat high blood pressure. When testing was done in the lab, DRUG B had an LD50 of 100 mg/kg in mice. Based on what you have seen in the PowerPoint, and the YouTube videos, draw...
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?
Drug A has a Vd of 0.65 L/kg. If target concentration TC = 20 mg/L, what is the appropriate loading dose for a 90kg patient? Why would you want to use a loading dose?
Drug X is a new oral cephalosporin. the package insert states the following: feu=0, F=9,fb=0.6, CLtotal=0.21L/h/kg, po dose=3.6 mg/kg q6h, Qp=0.8L/h/kg what is the hepatic extraction ratio of drug x? is drug x restrictive or non-restrictively cleared? will enzyme induction cause a significant interaction for drug x? what is the Cssaverage of drug x in a 70kg patient at the po dose given above?
