A method based on the convolution technique has been described earlier to predict plasma drug concentration-time (C-t) profiles. This article describes further refinement of the method for a more realistic representation of a human bioavailability study outcome by including variabilities in stomach emptying time and bioavailability factor (F). The advantages of such refinement are discussed, including setting physiologically relevant specifications for dissolution testing. Please click here for the complete article
PS: Please note that an error in the text was detected on page 2, column 2, and paragraph 2, which has been corrected. The revision reads as follows: “For this particular example, it is assumed that the filter will release (not adsorb) on average 44%±10(±SD) of the drug, representing average F (bioavailability) and variation in the F for diltiazem.” My apologies for the oversight and any inconvenience it may have caused.
