Study Notes
Objectives
- Understanding basic information about various routes of drug administration.
- Identifying appropriate administration routes for different patients.
- Evaluating the advantages and disadvantages associated with each route.
Introduction to Pharmacokinetics
- Pharmacokinetics involves studying drug movement over time within the body.
- Key process: Absorption of drugs allows therapeutic agents to enter the plasma.
Categories of Routes of Administration
- Enteral Routes: Administration via the gastrointestinal tract (e.g., oral, sublingual).
- Parenteral Routes: Injections bypassing the GI tract (e.g., intravenous, intramuscular, subcutaneous).
- Other Routes: Various alternative methods (e.g., inhalation, intranasal, rectal, topical).
Determining Routes of Administration
- Selection based on drug properties (e.g., water/lipid solubility, ionization).
- Consideration of therapeutic goals (e.g., rapid onset, long-term treatment, local effect).
Enteral Routes
-
Oral Route: Commonly administered by mouth, effective for conscious patients (adults and children).
-
Sublingual Route:
- Advantages: Bypasses the first-pass effect, rapid absorption, convenient, low infection risk, stable drug pH.
- Disadvantages: Risk of swallowing medication, not suitable for high-dose drugs.
Parenteral Routes
-
Intravenous (IV) Route:
-
Direct injection into the bloodstream ensures 100% bioavailability.
-
Two types:
- Fast IV Injection: Immediate administration useful in emergencies.
- Slow IV Infusion: Sustained administration over time.
-
Advantages: Avoids absorption issues, rapid action, ideal for drugs not stable or absorbable orally.
-
Disadvantages: Causes discomfort, requires aseptic conditions, risk of infection, potential for extravasation.
-
-
Intramuscular (IM) Route:
-
Injection into muscle tissue with various absorption rates based on injection site.
-
Advantages: Suitable for moderate volumes, supports oily preparations, can be self-administered.
-
Disadvantages: Painful, risk of nerve injury, limited volume compared to IV, requires healthcare professional for administration.
-
-
Subcutaneous (SC) Route:
-
Injection beneath the skin into the adipose layer, usually in the arm, thigh, or abdomen.
-
Advantages: Allows slower drug absorption.
-
Disadvantages: Limited injection volume, potential irritation from non-isotonic solutions.
-
Other Routes
- Topical Route:
-
Epidermic: Local effects targeting skin conditions using creams, ointments, gels.
-
Transdermal: Systemic effects via skin patches, avoids first-pass metabolism.
-
Advantages: Local effect, enhanced compliance, convenience of application.
-
Disadvantages: Challenges with drug absorption due to size and lipid solubility, risk of local irritation.
