Abstract:
Targeted intrathecal drug delivery (TIDD) has the objective of bringing the drug(s) close to the receptors influencing pain modulation, and thus reducing the dose and the side effects. Intrathecal drug delivery knew its real start with the development of permanent implantation of intrathecal and epidural catheters, combined with internal or external ports, reservoirs, and programmable pumps. TIDD is a valuable treatment for patients with cancer suffering refractory pain. Patients suffering noncancer-related pain should only be considered for TIDD when all other options have been tested, including spinal cord stimulation. Only two drugs are approved by the US Food and Drug Administration for TIDD administration for chronic pain: morphine and ziconotide as monotherapy. In pain management, off-label use of medication and combination therapy is often reported. The specific action of the intrathecal drugs, the efficacy and safety, is described, as well as the modalities for trialing intrathecal drug delivery and the implantation methods.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
