Glossary

Medicine delivery systems encompass four main related aspects:

1. Routes of delivery (ways in which the medications can be taken, such as orally, by injection, by inhalation, etc.).
   
2. Delivery vehicles (dosage forms such as pills or slow-release granules).
   
3. Chemical/biological properties of the active substance of the medicine (the cargo).
   
4. Targeting strategies (delivery methods that deliver medicines to specific organs, tissues, tumours or structures inside of cells).
