Study Notes
Routes of Drug Administration
- Direct application of a drug to the desired site of action is achieved through local administration.
- Local effects are commonly obtained through administration to the eye, nose, or skin.
- Intravenous injection allows for direct placement of a drug into the bloodstream, facilitating rapid systemic effects.
Dosage Form Design Considerations
- A fundamental consideration in dosage form design is the intended effect of the drug: whether local or systemic.
- Systemic effects require the drug to enter the circulatory system, while local effects target specific sites directly.
Absorption and Circulation
- For systemic effects, drugs may be absorbed into the venous circulation following oral administration.
- Absorption into the venous circulation following local administration leads to a gradual systemic effect.
- Understanding the route of administration is crucial for achieving the desired therapeutic outcome.
