Quantitative Estimation of the Factors Affecting VRD-ODTs 4shows the estimate effect of each factor, F-ratio and p-values for Y 1 and Y 2 from two-way analysis of variance (ANOVA). Low bioavailability is most common with oral dosage forms of poorly water-soluble, slowly absorbed drugs. Insufficient time for absorption in the GI tract is a common cause of low bioavailability. If the drug does not dissolve readily or cannot penetrate the epithelial membrane (eg, if it is highly ionized and polar), time at the absorption site may be insufficient.
