A patient comes into your office presenting with a bacterial infection. You prescribe 500 mg azithromycin (oral). From what you know about this drug, the peak plasma concentrations range from 0.35-0.45 mg/L. Assuming a plasma concentration of 0.40 mg/L, what is the Vd of this drug?
Homework Answers
ordered dose= 500 mg
peak plasma concentration range=0.35-0.45 mg /L
plasma concentration=0.40 mg/L
Vd=?
Formula: Vd= amount of drug in the body at a particular time / plasma drug concentration at that time
Vd=500mg / 0.40 mg/ L
Vd=1250 L
1250 L is the Vd of azithromycin drug.

Azithromycin is sometimes prescribed for community acquired pneumonia as 500 mg PO on day 1 then 250 mg PO on days 2-5. You are asked to evaluate the possible maximal lung concentration of azithromycin after the final dose according to these dosing instructions in a male patient who weighs 158 lb. A report in the literature stated that azithromycin lung concentrations are 1030% of azithromycin blood concentrations. Assume azithromycin has an elimination half-life of 53 hr, an absorption half-life of...
