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