Greater the lipid water solubility coefficient, more is the lipid solubility of the drug and greater is the absorption. Less the coefficient, less is the lipid solubility and less is the absorption. Water film exists on the membranes so part of the drugs must be water soluble to cross this water film.Drugs with benzene ring, hydrocarbon chain, steroid nucleus and halogen groups in their structures are lipid soluble.rea of Absorptive Surface. Area of absorptive surface affects oral as well as other routes. Most of the drugs are given orally because of the large area of absorptive surface, so that greater absorption occurs. Intestinal resection decreases the surface area leading to a decreased absorption.
For orally administered drugs, remember that the. blood supply draining the gut passes through the liver before reaching the. systemic circulation. Since the liver is a major site of drug metabolism, this first-pass effect may reduce the amount of drug reaching the target. tissue. In some cases, the first-pass effect results in metabolic activation. of an inert pro-drug.
