Fig. 1From: Modelling concentrations of antimicrobial drugs: comparative pharmacokinetics of cephalosporin antimicrobials and accuracy of allometric scaling in food-producing and companion animalsTwo examples of allometric analysis performed on pharmacokinetic data of cephalosporins. Figure shows clearance, volume of distirubution and half-life of ceftazidime (3rd generation cephalosporin) and cefquinome (4th generation cephalosporin). Ceftazidime is also used in human medicine, human data are included in this figure and the equation and R2 shown are based on allometric analysis including human dataBack to article page
