WebBasic enzyme kinetics graphs Graphs like the one shown below (graphing reaction rate as a function of substrate concentration) are often used to display information about enzyme kinetics. They provide a lot of useful information, but they can also be pretty confusing the first time you see them. Web1. feb 2024 · Nonlinear Pharmacokinetics • Most of the rate processes discussed in this course, except for the infusion process, follow first order kinetics. • For a few drugs it is observed that the elimination of the drug appears to be zero order at high concentrations and first order at low concentrations.
WebPhenytoin is a relatively insoluble weak acid, usually administered as the sodium salt. Bioavailability is dependent upon particle size and problems of generic inequivalence have therefore arisen, particularly in Scandinavia. The drug has a moderately large volume of distribution and is approximately 90% bound to plasma proteins.
