WebCalculator for correction of valproic acid levels. In blood, most drugs are bound to serum proteins. The fraction bound to proteins is considered to be pharmacologically inactive, as only the unbound (free) fraction is available for diffusion out of the vascular system to sites for pharmacological action. The valproic acid-protein binding depends on both the serum … WebAbout. Phenytoin has significant albumin binding and when total phenytoin level is measured, it is assumed that the amount bound to albumin versus free is predictable. In advanced renal failure, there is reduced phenytoin binding to albumin and one will tend to underestimate free phenytoin levels. The correction factor provided in this tool ...
