Peripheral nervous system drug delivery route

Peripheral nervous system drug delivery routes are mainly the following:

1, oral drug delivery: through the oral cavity into the body, through the intestinal absorption into the blood circulation, and ultimately reach the peripheral nervous system.

2, injection drug delivery: including subcutaneous injection, intramuscular injection, intravenous injection, etc., the drug can directly enter the blood circulation, and quickly reach the peripheral nervous system.

3. Patch administration: the drug is absorbed through the skin, enters the blood circulation, and finally reaches the peripheral nervous system.
