Routes of Drug Administration Quiz

Routes of Drug Administration

• Parenteral route is suitable for drugs destroyed by gastrointestinal enzymes, as it bypasses the digestive system.
• The advantage of the buccal route of drug administration is that it allows for rapid absorption of the drug into the bloodstream, while avoiding hepatic first-pass metabolism.
• The gastric gavage route is commonly used in research involving animals, particularly in toxicology studies.
• The intravenous (IV) route offers 100% bioavailability, as the drug is directly injected into the bloodstream.
• The disadvantage of the oral route of drug administration is that it is susceptible to hepatic first-pass metabolism and degradation by gastrointestinal enzymes, which can reduce the bioavailability of the drug.
