Question

a 55 year old female patient with oesophageal candidiasis is ordered 100 mg intraconzzole to be swished around the mouth and swallowed twice daily. the available solution contains 10/ml intraconazole.
what volume is required ?

Answer 1

Given,

a 55 year old female patient with oesophageal candidiasis is ordered 100 mg intraconzzole to be swished around the mouth and swallowed twice daily.

Hence, each dose = 100 mg

the available solution contains 10 mg/ml intraconazole.[ that means 10 mg intraconzzole present in 1 ml solution. ]

Using unitary method:-

10 mg intraconzzole present in 1 ml solution.

1 mg intraconzzole present in = 1/10 ml solution

100 mg intraconzzole present in = (1/10) ×100 ml solution

=10 ml solution

Therefore, 10 ml intraconzzole is required per dose.

Now,

intraconzzole to be swished around the mouth and swallowed twice daily.

Hence, volume of intraconzzole required per day = 10×2 ml

=20 ml

Therefore, 20 ml solution of intraconzzole is required per day
