Summary Introduction
To determine: The half-life of a drug based on the information given in the graph.
Introduction: A drug is a medicine or any other substance that shows a physiological effect when introduced to the body. A drug can be inhaled, injected, smoked, consumed, absorbed by the skin, and dissolved under the tongue.

Answer the following step by step
a) If you have a vial of dexamethasone with 4 mg/ml, how much do you need for a 1-mg dose?
b) If Cogentin is available as 0.5 mg/tablet, how many tablets do you need for a 1-mg dose?
Your doctor is determining which drug would best treat your ailment - a drug with a low dissociation constant and a few significant side effects or a drug with a high dissociation constant and many mild side effects. There's no perfect choice, so they go with the first choice. What does this mean for you?
A) You'll need a relatively low dose of the drug to be effective and chances of side effects are low
B) You'll need a relatively high dose of the drug but the chances of side effects are low.
C) You'll need a relatively high dose of the drug but the side effects are not expected to be harmful
D) You'll need a relatively low dose of the drug but the risk of side effects is high.
The order is for 0.35 mg of epinephrine stat; the drug is available as an ampule with

volume should be administered to the patient per dose?
1) 0.035 mL
2) 0.35 mL
3) 3.5 mL
4) 35 mL

- The initial plasma concentration of a drug given iv at 8:00am is 210 mg/ml. If the half life of the drug is 6 hours, what will the plasma concentration be at 7:00pm that same day?arrow_forwardFirst, we will build a model for the total amount of drugs in the gut. At time \(t = 0\), \(10mg\) of the drug is present in the gut. From the gut, it passes slowly into the blood. The passage of the drug to the blood has first-order kinetics; that is, every hour \(42\%\) of the drug remaining in the gut is passed from the gut into the blood. No more pills are taken, so no extra drug is added to the gut. Let \(a_t\) be the sequence representing the amount of Adderall XR in the patient’s gut \(t\) hours after the pill was taken. Write down a recursion relation for \(a_t\). Find an explicit formula for \(a_t\). Calculate the time at which the amount of drug remaining in the gut drops to \(1\%\) of its starting value; that is, find \(t\) for which \[a_t = 0.01a_0\] Find \(\lim_{t\to\infty}a_t\), what does it represent?
