Lidocaine is a medication which is commonly used as a local analgesic (numbs tissue in a specific area). The average half-life of Lidocaine elimination from the plasma following IV administration is 94 min (first-order kinetics). A dose of Lidocaine was administered via IV, and initial concentration of drug in plasma was 3.63 mcg/ml. Determine the elimination rate constant in and how long will it take for the drug concentration to drop to 10% of its initial value (in hours).

13. Aspirin is a common anti-inflammatory medication. A drug dose was administered orally and initial concentration of Aspirin in plasma was 33.2 mg/L. Knowing that Aspirin elimination follows zero order kinetics and drug half-life is 15 min. Determine: How long will it take for a drug concentration to decrease to 5% of its initial value? What is the elimination rate constant?

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?

An adult male (73 years old, 65 kg) with diabetes mellitus is placed on hemodialysis. His residual creatinine clearance is <5mL/min. The patient is given tobramycin, an aminoglycoside antibiotic, at a dose, at a dose of 1 mg/kg by IV bolus injection. Tobramycin is 90% excreted unchanged in the urine, is less than 10% to plasma protein, and has elimination half-life 2.2 hours in patient with normal renal function. In this patient, tobramycin has an elimination t1/2 of 50hours during...

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...
