The document discusses the oral route of drug administration. It notes that the oral route is the oldest and simplest route, where drugs are administered through the mouth either as solid or liquid dosage forms. It has advantages of being safe, convenient, painless and economical as sterilization is not required. However, it also has disadvantages like incomplete drug absorption, first-pass metabolism, inability to use in emergencies or for unconscious patients, and potential side effects like nausea from gastric irritation.
