ENTERAL ROUTES OF DRUG ADMINISTRATION Orаl Rоute (PO) Cоre cоncept Drug is swаllowed аnd absorbed through gastrointestinal tract → systemic circulation. Advantages Easiest route; self-administration Highly convenient for long-term therapy Best patient compliance Absorption can be stopped (vomiting, spitting, purgation) Disadvantages First-pass metabolism (liver/GIT) → ↓ bioavailability Not suitable for emergencies (slow onset: ~30–90 min) Not suitable for protein/peptide drugs (acid + enzymes degrade) Not usable in vomiting or unconscious patients Poor tolerance for bitter/irritant drugs Food-drug interactions can alter absorption Sublingual & Buccal Routes Core concept Drug absorbed directly through oral mucosa → systemic circulation (bypasses GIT). Dosage forms Tablets Films Sprays Pellets Advantages Rapid onset (1–5 minutes) → useful in emergencies No first-pass metabolism Avoids gastric acid and digestive enzymes Can be stopped by removing drug (spitting) Suitable for some protein drugs No effect from food or GIT pH Disadvantages Not suitable for bitter/irritant drugs Limited surface area → not suitable for high doses Not usable in unconscious or vomiting patients Rectal Route Core concept Drug administered via rectum → absorption through rectal mucosa (suppositories/enemas). Dosage forms Suppositories Enemas Advantages Useful in emergencies (can be relatively rapid) Ideal for vomiting or unconscious patients Useful in pediatrics Avoids gastric irritation and food effects Can be used for drugs degraded by enzymes Disadvantages Patient discomfort → poor compliance Irregular and unpredictable absorption Not suitable for irritant drugs Partial first-pass metabolism (especially upper rectum drainage into portal circulation) Question: An elderly patient with acute chest pain is given nitroglycerin to be placed under the tongue for rapid symptom relief. Which advantage best explains the choice of this route of administration?
