WebTo perform allometric scaling and to predict pharmacokinetic parameters in humans at least three animal species are generally required. It is postulated that the more the number of animals, greater the chances of precise predictions of pharmacokinetic parameters. However, allometric scaling for more species are time consuming and costly [3].
