Study Notes
Routes of Drug Administration
- Enteral routes include sublingual/buccal, oral, and rectal routes.
- Parenteral routes include intravascular, intramuscular, subcutaneous, intradermal, and inhalation routes.
- Topical routes include external topicals and internal topicals.
Enteral Routes
- Sublingual/buccal route: drugs are taken as smaller tablets, held in the mouth or under the tongue. • Advantages: rapid absorption, drug stability (e.g., nitroglycerin for rapid relief of angina).
- Oral route: used for systemic effect, substance is given via the digestive tract. • Disadvantages: sometimes inefficient, irritation to gastric mucosa.
- Rectal route: most commonly by suppository or enema. • Advantages: useful for patients unable to take drugs orally.
Parenteral Routes
- Intravascular route: inject drug directly into the bloodstream. • Advantages: accurate and immediate onset of action. • Disadvantages: high concentrations leading to greater risk of adverse effects.
- Intramuscular route: inject drug directly into the skeletal muscle. • Disadvantages: pain at injection site.
- Subcutaneous route: highly effective in administering vaccines and medications (e.g., insulin). • Advantages: slow and constant absorption. • Disadvantages: absorption limited by blood flow, affected if circulatory problems exist.
- Inhalation route: lungs provide an excellent surface for absorption when the drug is delivered in gaseous or aerosol form. • Advantage: rapid onset action due to rapid access to circulation.
Topical Routes
- Topical route: drugs are applied topically to the skin or mucous membranes, mainly for local action. • Examples: skin, otic, vaginal, ophthalmic.
Classification of Drugs According to Their Action
