She experienced severe withdrawal symptoms. Keywords: Ondansetron, Opioid withdrawal syndrome, Oxycodone, OxyContin. Go to:.

In all seven men, ondansetron significantly reduced all 12 of those signs ( P  = 0.0313). Evaluation of the effects on all of the human subjects showed that seven of the eight volunteers developed 12 of 13 objective signs of withdrawal. The 16 subjective symptoms, however, were not shown to be significantly lower with the use of ondansetron.

Addiction is a relapsing compulsion to obtain and use the drug even after successful withdrawal and in spite of negative effects. Tolerance, a gradual loss of effectiveness, occurs during treatment when large doses of opioid are given close together. People show physical dependence on opioids when they are abruptly stopped. Physical dependence should not be confused with tolerance or addiction. The number and intensity of the signs and symptoms of withdrawal are dependent upon the degree of physical dependence that has developed. Withdrawal signs usually start within 6–10 h after the last dose.

A Canadian study concluded that 5-HT 3 antagonists (ondansetron, and MDL 72222) might reduce some, but not all, signs and symptoms of withdrawal behavior induced by naloxone. One study found that it did not reduce the cravings of opiate addicted rodents, while another suggested that it could be useful in lowering the rate of relapse. Other researchers varied in their conclusions regarding the effectiveness of ondansetron. Data reported by a group from Italy confirmed that naloxone precipitated withdrawal signs in morphine-dependent rats, and, that ondansetron prevented several of those signs.

Institutional Review Board approval from the University of Tennessee at Chattanooga and written permission from the subject were obtained. Verbal agreement was received from the subject’s surgeon to allow dissemination of information related to her surgery and postoperative recovery.

A rib was removed, a chest tube was inserted, and discs between T10, T11, T12, and the remaining lumbar vertebrae were temporarily replaced. After surgery, the patient complained of quite a bit of referred pain in her shoulder. She rested on days 3 and 4, but was back in surgery for several hours on day 5. The next day, surgery was performed anteriorly from a left-side incision. Because the vertebra were scraped to allow fusion with the grafts, the patient required replacement of 14 U of blood. Her first surgery was accomplished through a lower abdominal incision. A posterior incision allowed the surgeon to remove the discs from T3 to T9, rotate the spinal column from 85° to 27°, fixate it with rods, screws, and wires, and insert donor bone grafts between all the vertebra. Lumbar vertebra 5 (L5) was replaced by a titanium prosthesis, and a donor bone graft was used to replace the disc.

After 10 days, the patient was opioid and withdrawal-symptom free.

as needed for breakthrough pain. On day 9 her controlled-release oxycodone dose was increased to 20 mg at 7:00 a.m., 3:00 p.m., and 11:00 p.m. Epidural analgesia was attempted but did not provide any pain relief, so she was maintained on the PCA through day 7. Postoperatively, the patient had intravenous (i.v.) patient-controlled analgesia (PCA) with morphine. She was discharged from hospital that afternoon. She was then started on 20 mg of controlled-release oxycodone (OxyContin®; Purdue Pharma L.P., Stamford, CT, USA) to be taken orally (p.o.) twice a day, with 5 mg of fast-release oxycodone p.o. Fast-release oxycodone 5 mg was continued for breakthrough pain.

They entailed making her position comfortable, adjusting the clamshell, replacing SpinalPak® batteries, and relieving constipation associated with the surgery and the opioids. The following days were difficult for her. A bivalve orthosis (clamshell brace) and two SpinalPak® II Fusion Stimulators (EBI, LLC dba Biomet Spine & Bone Healing Technologies, Parsippany, NJ, USA) were prescribed to stabilize the patient’s spine and to stimulate bone growth.

This case should stimulate research with a larger, more diverse population including those with both short-term and chronic opioid dependence. Use of ondansetron along with tapering of the opioid was safe and effective in preventing further withdrawal symptoms.

The study showed that naloxone could precipitate withdrawal signs and symptoms after acute morphine administration similar to those observed after chronic opioid use. He posited that 5-HT 3 antagonists might have the ability to block feelings of reward induced by drug-craving addicts. That same year, a scientist from the UK reviewed several studies and called attention to the fact that cerebral membranes of both the rat and humans contained sites that were characteristic of 5-hydroxytryptamine3 (5-HT 3 ) receptors. Keywords used were “oxycontin,” “opioid withdrawal,” “taper,” and after seeing a referral in one article, “ondansetron.” A 1986 article from the Johns Hopkins University Hospital described a pilot study of three adult post-addict males who were given different doses of morphine or placebo on 12 mornings followed by 10 mg of naloxone in the afternoons. A review of the literature was conducted through PubMed and yielded many articles dealing with withdrawal from opiates.

This report describes the case of an individual who was assisted in relieving her physical dependence on oxycodone. Patients who have been prescribed an oral opioid postoperatively and who take the drug for 2 or more weeks usually report experiencing withdrawal symptoms when the drug is discontinued. It provides an insight into the reason for her surgery, the surgery itself, and her postoperative course. It also reviews medications used, and describes the protocol followed to produce successful results.

Eight human volunteers, all males, were then recruited, and served as their own controls. Four volunteers received a 0.9% saline placebo administered intravenously (i.v.) followed by morphine 10 mg/70 kg (i.v.). Baseline data were obtained by using objective and subjective rating scales. Two hours after the first set of drugs were administered, all participants received 10 mg/70 kg of naloxone (i.v.) to induce withdrawal symptoms. Seven days later the volunteers were administered the same drugs. Both objective and subjective signs of withdrawal were assessed and compared to the baseline survey. The four men who had received placebos in the first experiment received both ondansetron and morphine while the remaining four received the placebo and the morphine. The remaining four volunteers were pretreated with 8 mg of ondansetron (i.v.), and then received morphine 10 mg/70 kg (i.v.).

Patients who are discharged following surgery on an oral opioid, and who have taken the drug for 2 or more weeks often experience withdrawal symptoms when they try to discontinue the drug.

Peripheral effects are sometimes seen on the cardiovascular system in patients with hypotension, in the gastrointestinal tract (causing constipation), on the biliary tract, on the functioning of the renal system, on the neuroendocrine system, and in the skin (causing pruritus and sweating). The principle central nervous system effects of opioids are analgesia, euphoria, sedation, respiratory depression, cough suppression, pupil constriction, and temperature changes. Effects are also seen in the immune system.

To assist her in withdrawing from the remainder of the drug, a protocol using ondansetron was developed.

The mice were treated with subcutaneous (s.c.) morphine in increasing doses over 4 days, assessed 18 h after the last dose, and then given naloxone s.c. The ondansetron-treated mice showed significantly decreased naloxone-induced withdrawal behavior. which precipitated varied degrees of withdrawal behavior depending upon the strain of the mice used. The researchers used ondansetron, to determine its effect on the morphine-dependent mice. In 2009, a research group from Stanford University assessed opioid withdrawal behavior in 18 different strains of mice and in eight human volunteers.

She experienced severe withdrawal symptoms. Three weeks after discharge, a 44-year-old female patient decided to reduce her oxycodone (OxyContin®) dosage from 20 mg three times a day to 20 mg two times a day.

During the first week at home the patient took approximay three oxycodone 5 mg tablets for breakthrough pain, but by the following week she was able to gradually discontinue it. She became more active and was able to climb the stairs to the second floor of the house in spite of some left leg and foot neuropathy. She was anxious to be able to drive her car, but thought that she should not do so while she was still taking the controlled-release oxycodone.

As for a safe dose in adults and children over 12 years of age, oral ondansetron is given as an 8 mg tablet, 30 min before and again 8 h after an initial dose of chemotherapy or radiation therapy. Then, 8 mg is given every 8–12 h for 1–2 days.

She was reassured that the ondansetron acted on different receptors in the body than did the opioids, and that her prior withdrawal symptoms had been normal for what she had been through, and not symptoms of addiction. During the 10 days of the weaning process, the patient neither exhibited nor voiced any symptoms of withdrawal from the opioid. This reassurance stemmed from knowing that antidepressants, which (like ondansetron) block serotonin uptake, have not been shown to cause addiction even after prolonged use. In fact, she expressed fear of becoming dependent on the ondansetron because of the feeling of well-being it gave her.

To alleviate or prevent the signs and symptoms of opioid withdrawal and to combat the possibility of some of these people becoming addicts, it would be wise to conduct randomized controlled trials on both males and females, young and old, with both acute and chronic opioid dependence (not associated with a terminal condition), to determine the effects of ondansetron given prior to beginning tapering off of the opioid. As these people grow older, it can be postulated that the incidence of oxycodone dependence will increase. Statistics are already showing increased percentages of knee, hip, shoulder, and back surgery in people born between 1946 and 1964 (“baby boomers”), an age group that has engaged in more active sports than any previous generation. Military personnel are also seeing an increase in opiate dependence. Reducing dependence on oxycodone is a big hurdle for many people who have had orthopedic or other major surgery.

An assessment by an orthopedic surgeon recommended by the Scoliosis Research Society revealed that she had also developed some neuropathy in her left lower limb. She was in good health and had a body mass index below 25. Her only pain medication was an occasional extra-strength acetaminophen. Surgery was deemed medically necessary. A magnetic resonance imaging scan verified thoracic dextroscoliosis and lumbar levoscoliosis with degenerative changes in both areas. She showed no cosmetic effect, nor was there any pressure on her internal organs related to the scoliosis. The patient, a female, was 14 years old when she was diagnosed with scoliosis. At age 44, a rib on her left side became noticeably more prominent and measurements showed that she had lost close to two inches in height.

Serotonin is accepted by 5-HT 3 receptors located in the chemoreceptor trigger zone of the brain (area postrema), the vomiting center in the medulla, and in the gastrointestinal tract. Ondansetron is tolerated well and has an excellent safety record. It participates in the vomiting reflex, especially in vomiting caused by chemical triggers. It has proved to be therapeutic in preventing nausea and vomiting related to surgery, chemotherapy, and whole body or abdominal radiation therapy. Serotonin is both a powerful stimulant of pain and a strong activator of chemosensitive endings. Ondansetron has been used in the treatment of irritable bowel syndrome, and a Cochrane Collaboration review described its use in relieving acute gastroenteritis in children and adolescents. Ondansetron is a 5-HT 3 antagonist that blocks the action of serotonin.

The patient was assisted in becoming oxycodone free, by tapering the doses of oxycodone and by using ondansetron to make the process more tolerable. Ondansetron had reduced artificially induced withdrawal symptoms for eight male volunteers, but the question remained as to whether ondansetron could help alleviate withdrawal in a 44-year-old premenopausal woman who had been on oxycodone for 5 weeks.

At the conclusion of the protocol, the patient disposed of the remaining oxycodone according to the Food and Drug Administration (FDA) guidelines. She was featured as a model patient after a month of visits to a physical therapy group. Some may argue that the same effect could have been achieved by simply tapering the dose of opioids at a slower rate and over a longer period of time. For instance, the patient could have been advised to remove only 10 mg of the middle dose of oxycodone, wait 4 days and remove 10 mg of the evening dose, then wait the same number of days and remove 10 mg of the morning dose. She continues to walk daily on her treadmill and enjoys advanced hula-hoop exercises on the Wii™ (Nintendo®, Redmond, WA, USA). Since oxycodone does not come in smaller doses than 10 mg, and since controlled release could not be effectively achieved by cutting the tablet in half (5 mg), the patient may have had to endure some withdrawal symptoms as the remaining doses were discontinued over a 30-day period.

It began 48 h before the first dose reduction in oxycodone and continued until 48 h after the last dose of oxycodone. The evening dose of oxycodone was the first to be reduced to 10 mg. Ondansetron 8 mg was given at 8 a.m. every day during the treatment period. The patient obtained prescriptions for oxycodone 10 mg and for oral ondansetron 8 mg. and 8 p.m. The planned protocol can be seen in Table  1.

She was afraid to reduce the remaining doses of oxycodone and asked for assistance. She decided to take 20 mg of oxycodone at 8 a.m. She showed the following signs of withdrawal: crying, cold flashes, piloerection, muscle twitches, tremors, hot flashes, and perspiration. By 5 p.m. She described symptoms of: abdominal cramps, feeling nauseous and ready to vomit, shaking, and eye twitching. that same day, she became anxious and extremely depressed. Twenty-five days after receiving her first opioid and almost 3 weeks after discharge from the hospital, the patient discontinued the middle dose of oxycodone, contrary to usual pain management protocols, which recommend partial decreases at each dosage time over many days. and 20 mg at 8 p.m. These signs and symptoms lasted over 48 h.
