Understanding First Pass Metabolism. The drug is absorbed from the GI tract and passes via the portal vein into the liver where some drugs are metabolised. Sometimes the result of first pass metabolism means that only a proportion of the drug reaches the circulation. First pass metabolism can occur in the gut and the liver. For example, first pass metabolism occurs in the gut for benzylpenicillin and insulin and in the liver for propranolol, lignocane, chloromethiasole and GTN.
Meconium, which is made up of amniotic fluid, bile, and shed skin cells, begins to collect in your babyâs intestines while he is in your womb. When your baby has his first bowel movement, he will empty the meconium that has been collecting. Most babies start to pass meconium within 12 hours of their birth. Not passing meconium during the first 24 hours can be a sign of a complication such as an intestinal obstruction. Occasionally, babies have their first bowel movement in utero. This can happen if baby is in distress.
