Naltrexone, developed in 1960, was approved in 1980. Mayo Clinic, Johns Hopkins Hospital, Cleveland Clinics, UCLA Medical Centers, Stanford Hospitals, and other top medical facilities have used it in a specific dosage to treat certain conditions. Health practitioners are now using the drug at much lower doses. Low doses of Naltrexone have proven effective, but patients need to be aware of what they should avoid.
What is Naltrexone exactly?
Naltrexone an FDA-approved drug in the category of opioid antagonists, is a medication that the FDA has approved. The drug is sold under the brands Revia and Vivitrol. It is used primarily to treat alcohol use disorders and opioid disorders. It is a drug that can be used to help people stop drinking and using drugs. However, it cannot replace counseling or a full addiction treatment. Naltrexone doesn’t prevent withdrawal symptoms when people stop using opioids or alcohol.
ReVia and Depade come in pill form. The full-strength dosage is 50mg per day. This can be taken with or without meals. In a rehabilitation center or clinic, Naltrexone can be prescribed daily, every other day, or twice weekly. It may also be prescribed daily for six days of the week. Vivitrol is the injectable form, which contains 380mg of Naltrexone. It’s prescribed once a week at a dose of 380mg.
You can interfere with heroin, codeine, and morphine in different ways. Certain medications activate opioid receptors, which suppress cravings. Naltrexone blocks and binds opioid receptors. This reduces opioid cravings. Naltrexone does not cause dependence or habit.
While taking Naltrexone, people mustn’t take any other opioids or illicit drugs.
Low-Dose Naltrexone Usage
Low-dose Naltrexone can be used to treat chronic and fibromyalgia pain. The drug is also prescribed for neurological, psychological, and gastrointestinal disorders. Low-dose naltrexone has been named to treat inflammation. However, fewer studies support its efficacy.
Research on Low Dose Naltrexone
Diverse studies have contributed to a better understanding of Low Dose Naltrexone’s effectiveness and how it works.
Chronic Pain
A systematic review of LDN published in Current Pain & Headache Reports in 2020 stated that Naltrexone has “shown promise” to reduce the symptoms associated with chronic pain conditions such as fibromyalgia and inflammatory bowel diseases. Doctors at the Center for Interventional Pain & Spine, Delaware, reported that LDN seems to work by modulating inflammation within the brain’s glial cells and modulating compounds associated with inflammation in the central nervous system. These effects are only present at low doses.
Effects of Immune System
Three researchers from the Regis University School of Pharmacy, Denver, published the results of their study in 2018 on the use of low-dose Naltrexone to treat off-label conditions. Highlighted that low doses of Naltrexone could inhibit the reproduction of immune cells T and B. It can also block Tolllike receptor 4, resulting in a decrease in pain and inflammation.
Researchers believe that there is sufficient evidence to support the safe use of Naltrexone for treating fibromyalgia and other conditions such as Crohn’s, multiple sclerosis, and fibromyalgia.
Hope For Patients With Inflammatory Bowel Disorder (IBD)
Seven researchers from the Erasmus MC University Medical Centre Rotterdam, Netherlands, conducted their clinical study on 47 IBD patients. They were prescribed low-dose Naltrexone over 12 weeks. In 2018, they published their results in the Journal of Translational Medicine, demonstrating clinical improvements in 74.5% of patients and remissions in 25.5%. The low dose directly improved epithelial cell function in the bowel by enhancing wound healing. Researchers concluded that it was safe and effective and could be used as a treatment by people with IBD if they haven’t had success with any other medicines.
Amitriptyline Results for Diabetic Patients
Amitriptyline is a prescription drug that can be used to treat painful diabetes neuropathy. It comes in doses of 10 to 25/50mg. In India, a team of doctors decided to compare amitriptyline with low-dose Naltrexone (2-4 mg).
The researchers started 67 patients with low doses of one of these drugs and increased their dosage if the pain reduction at a two-week follow-up was less than 20 percent. The procedure was repeated a second time. Then, after two weeks, patients were switched to another drug. This was repeated six times.
Amitriptyline caused sleepiness and fatigue in 52 of the 67 patients. Pain reduction was the same for those who used LDN and those who used amitriptyline. Doctors concluded that low-dose Naltrexone is as effective as amitriptyline for painful diabetic nerve pain. The study was published in the Journal of Diabetes 2021.
Low-Dose Naltrexone Treatment for Psoriasis
Low-dose naltrexone is effective in regulating the immune response. This is crucial for those with psoriasis. Researchers from the Washington University School of Medicine, in conjunction with a Danish hospital, tested 15 patients who had had psoriasis for over 16 years.
The doctors observed a marked improvement in 53% of patients after giving 4.5 mg oral naltrexone. Low-dose naltrexone was found to be safe, cheap, and effective by doctors.
Corneal Pain
The nerve that innervates your cornea is damaged by a condition called Neuropathic Corneal Pain. The pain can be accompanied by unpleasant feelings such as dryness, burning, or light sensitivity.
Tufts School of Medicine doctors tested 59 patients who had this type of corneal discomfort and prescribed low-dose naltrexone at bedtime (4.5 mg). This was given to them for at least four weeks. Most patients took the LDN for 17 months. However, some patients continued to take it up to 34. Eight patients received LDN exclusively, while the other study participants took it as a second therapy.
The low dosage of Naltrexone reduced the patients’ pain scores to 3.23 on a scale of 1-10. The patient’s overall quality of life improved compared to the last visit. Vivid dreams, headaches, and stomachaches were common side effects. The doctors concluded that LDN is effective and well-tolerated in the treatment of neuropathic pain.
Many case studies show the resolution of pain.
There are many case reports in the medical literature where low-dose Naltrexone has made a significant difference in pain or symptoms related to health disorders. These include:
* A 53-year-old woman who suffered from severe acne and scratching for 25 years, resulting in deep scarring of her face, received a 3-mg dose of Naltrexone. This reduced her itching and improved her quality of life. The University College London Hospitals published the case in 2021 in the British Medical Journal.
* A woman who was in her 70s and had suffered from Burning Mouth Syndrome for nearly ten years received a low dose of Naltrexone (4,5 mg), which helped to reduce the severity of her pain. The University of Kansas Medical Center reported this case study in 2021.
After receiving platelet-rich blood plasma and LDN, a patient with scarring and hair loss experienced remarkable hair growth; the patient’s response to topical agents and corticosteroids was minimal. She also had a low response to finasteride. This study was reported by the five researchers who were involved in it in the Journal of Drugs In Dermatology 2022.
