Nearly every day we receive an email from someone who is having trouble getting enough pain medication to give them a good quality of life.  In this age of opioid restrictions, there is hope. 

In the past, opioids and gamma amino butyric acid (GABA) substitutes such as diazepam (Valium) and gabapentin (Neurontin) have been the mainstays for pain control of adhesive arachnoiditis (AA). Today, there are alternatives that can enhance your current program to give you better pain control.

Low dose naltrexone is the initial pain reliever recommended to newly diagnosed AA cases. There are two other potent pain relievers that can be used with both naltrexone and opioids to achieve better pain relief: ketamine and oxytocin. Either agent is a good opioid substitute.

Ketamine provides pain relief primarily by suppressing a nerve receptor called N-methyl-d-aspartate. It can be taken by several non-oral routes of administration: nasal, injectable, sublingual or troche (dissolvable tablet).

Oxytocin (not to be confused with oxycodone or OxyContin) is a hormone that is a natural pain reliever. It surges in a woman’s body at the time of delivery to provide pain relief. It acts by activating the endorphin (opioid) receptors and by blocking nerve impulses between the brain and spinal cord.

Every community now has one or more pharmacies that will compound or “make” formulations of ketamine or oxytocin. We favor under-the-tongue (sublingual) or buccal (cheek) formulations.

Ketamine and/or oxytocin can be taken between opioid dosages or within 5 to 10 minutes before or after an opioid dosage to make the opioid stronger and last longer.

Ketamine and oxytocin can be used separately or used as combination therapy. Starting dosages of ketamine are 10-15 mg and oxytocin 10-20 units, which are administered within 10 minutes of each other. Dosages can later be raised above the starting dose.

We find the combination of ketamine and oxytocin to provide equal or better pain relief that most prescription opioids. Neither ketamine nor oxytocin are opioids, so there is no bias or resistance to their use. Also, overdoses are essentially not known to occur with regular dosages.
