Some substances are poorly absorbed, especially ones that are not water-soluble, like CBD. Drug formulation — excipients are non-active ingredients and influence drug formulation. Substances absorbed through the sublingual mucosa also evade hepatic first-pass effect, since the veins originating there do not join the portal system.

Important: Have in mind that, since enzymatic systems are saturable systems and generally, but, not always, described through the Michaelis—Menten kineticsthe fraction of the dose whose absorption will be affected by the first-pass effect will largely depend on the drug flux to the metabolizing organ.
For example: Amoxicillin has a bioavailability of 95 percent — meaning 95 percent of the drug reaches the systemic circulation. Transdermal products are topical formulations that actually do reach the bloodstream. There is a wide range of important enzymes in the liver — known as CYP enzymes — that interact with and metabolize drugs. Since the liver is the key explain first pass metabolism definition pharmacology definition in metabolizing drugs, any explain first pass metabolism definition pharmacology definition that affect it will also affect drug absorption. |

CBD drops can also be mixed in with food and drink, but taking them in that form would pass the first-pass effect. Topical formulations of CBD only need to be applied locally, wherever it is needed. These products penetrate the skin and interact with endocannabinoid receptors, but they do not reach the bloodstream.
