I want to do a study on ARV drugs herb pharmacokinetic interaction in human subject. So am looking for a formula i can use to determine sample size.
Dear Yusuf,
The following three links may be helpful:

Hoping this will be helpful,

This french website can help you :

You can calculate sample size with your criteria (means comparaison, % comparaison,....). This website work under R software.
Emeric
ss = Z 2 * (p) * (1-p)/c 2
Where:
Z = Z value (e.g. 1.96 for 95% confidence level)
p = percentage picking a choice, expressed as decimal
(.5 used for sample size needed)
c = confidence interval, expressed as decimal
(e.g., .04 = ±4)
Correction for Finite Population
new ss = ss/ 1+ ss-1/ pop
Where: pop = population
How we will calculate this sample
is there any online calculator to determine the sample size for population pharmacokinetic study in the human subjects?
Is There Any Feasible Method To Test The Efficiency Of Fluorescent Compounds Other Than UV Spectrometers ? Suggestions Would Be Appreciated !
