WebbSUMMARY Phenytoin elimination is a saturable process obeying Michaelis-Menten kinetics. Plasma phenytoin levels are not related linearly to dose, and small changes … WebbThe PK model of phenytoin assumes Michaelis–Menten kinetics. Therefore, owing to the relatively low concentration in the single-dose cases (when compared with a steady state), both V max and k m were involved in determining CL, necessitating the information split for the estimation of both parameters related to CL (again, when compared with a …
