Question

1. A physician orders Amoxil 250mg/5mL, give 200mg Q8H for seven days.
   1. How much do you give per dose

How much do you dispense altogether?

Answer 1

Given data

Order Amoxil 250mg/5ml- 200mg every 8 hour for 7 days

a. How much per dose

= (Ordered dose/available dose)xavailable volume

= (200mg/250) x 5

= 4 mL

4 mL should be given per dose to get 200mg of drug

b. Patient require 200mg per dose = 4 mL per dose

Drug is taken every 8 hourly that means 3 times a day

So, patient require 200mg x 3 = 600mg per day

or 4mL x3 = 12 mL per day

For 7 days 600 mg x 7 = 4200mg or 12 mL x7 = 84 mL

For 7 days patient require 4200mg of drug will be total volume of 84 mL

Available strength is 250mg /5 mL

Then for 7 days 4200/250 = 16.8 approximately 17 bottle of 250/5 mL
