- Sublingual (under the tongue)
- Rectal (through the anus)
-
Parenteral: outside the digestive system
- Intravenous (IV): into a vein
- Intramuscular (IM): into a muscle
- Subcutaneous (SC): under the skin
- Intradermal (ID): into the skin
- Intrapleural (IP): into the space between the lungs and chest wall
- Epidural (EP): into the space outside the spinal sac
- Intrathecal (IT): into the spinal fluid
Factors Affecting Drug Administration
