In zero order kinetics elimination of drug eliminated at a constant amount per unit time . And in first order kinetics elimination depends on concentration of drug .. but zero order kinetics is independent of concentration..
Hence DRUG A FOLLOWS ZERO ORDER AND DRUG B FOLLOWS ZERO ORDER KINETICS

18. List two drugs that display zero-order kinetics. 19. Drugs showing zero-order kinetics of elimination: a. Are more common than those showing first-order kinetics. b. Decrease in concentration exponentially with time. c. Have a half-life independent of dose. d. Show a plot of drug concentration versus time that is linear. e. Show a constant fraction of the drug eliminated per unit of time. 20. Acyclovir is a compound that is used to treat herpes simplex virus. In vivo activation of...

Two drugs (Drug A and Drug B) are being investigated for their effectiveness as anticonvulsants in the management of complex partial seizures and simple or complex absence seizures. In early preclinical development, they need to determine the affinity, efficacy, and potency for each drug. The results from the drug-receptor binding curves and the dose-response curves show that: 1) for Drug A it has a low Kd value, a high Emax, and a high EC50, and in comparison 2) Drug B...

Question 11 Not yet answered Points out of 1.0 The drug called BBX is eliminated from the body by first-order kinetics. This means that after the drug is administered and the blood concentration peaks, the concentration in the blood will then: Select one O a. decrease exponentially Flag question b. decrease linearly c. increase exponentially d. increase linearly

In order to treat a certain bacterial infection, a combination of two drugs is being tested. Studies have shown that the duration of the infection in laboratory tests can be modeled by D(x, y) = x2 + y2 - 12x - 30y + 2xy + 140 where x is the dosage of the first drug and y is the dosage of the second drug (both in hundreds of milligrams). Find the amount of each drug necessary to minimize the duration...

7. Smokers are known to have about 50% higher CL than nonsmokers for theophylline. If the average observed AUC after administration of 300 mg IV theophylline in nonsmokers is 100 mg.hr/L, what is the expected AUC in smokers after administration of the same 300 mg dose? Theophylline undergoes linear pharmacokinetics 2. After administration of a single 400 mg dose of a drug, a linear plot of the serum concentration-time prorile on a semi-log graph paper showed a y-intercept of 1mg/mL...

(26 points) Kineties of an Antiviral Drug. In 2016, Nature reported the discovery of a small molecule (GS-5734) that exhibited antiviral activity against the Ebola virus in rhesus monkeys (Nature, 2016, 331.381-385). That drug, now called remdesivir, is drawing renewed attention as a possible treatment for COVID-19. In the original study, the drug was administered by intravenous injection, 10 mg of GS-5734 per kg body weight of the rhesus monkey. A. (6 points) What's the typical body weight of a...

11 Properties of Radioactivity Prelaboratory Questions Name Laboratory Section 1. The decay behavior of a radioactive substance obeys first order kinetics: In (N/N.) = -kt, where N is the amount of radioactive nuclei at time = t seconds, N, is the amount at t = 0 seconds, k is the first order rate constant, and t is the elapsed time. If the half-life of the radioactive nuclei is 10 minutes, calculate the amount that remains after 75 seconds. (Hint: at...

4. Long-lasting drugs: One of the ways in which doctors try to determine how long a single dose of pain reliever will provide relief is to measure the drug's half-life, which is the length of time it takes for one-half of the dose to be eliminated from the body. A report of the National Institutes of Health states that the standard deviation of the half-life of the pain reliever oxycodone is o=1.43 hours. Assume that a sample of 25 patients...
