Question 3

A drug is to run as a CRI at 5 mcg/kg/min in a 10 kg dog. How many micrograms are delivered per minute?

Why might a loading dose of a drug be larger than the maintenance dose?

TheoryPractice · Accepted Answer

To rapidly reach an effective plasma concentration. A loading dose quickly fills the volume of distribution to reach therapeutic levels, after which smaller maintenance doses sustain them.

A cat weighs 4 kg and the drug dose is 10 mg/kg. The tablet strength is 20 mg. How many tablets are needed per dose?

2 tablets. Dose = 4 x 10 = 40 mg; 40 mg / 20 mg per tablet = 2 tablets.
