Abstract
Background: Tramadol is used off-label for medically supervised opioid withdrawal. Tramadol is metabolized by CYP2D6 to an active metabolite with significantly more pharmacologic activity compared to the parent compound.Objectives: The objective of this study is to evaluate the effects of CYP2D6 inhibitors on patient response to a tramadol taper for medically supervised opioid withdrawal.Methods: A retrospective chart review of patients who received a tramadol taper for medically supervised opioid withdrawal was conducted comparing patients who received concomitant moderate-to-strong CYP2D6 inhibitors to patients without concomitant therapy. The primary outcome was the change in Clinical Institute Narcotic Assessment (CINA) scores from baseline to discharge. Secondary outcomes included area under the curve of CINA scores over time, additional CINA outcomes, length of stay, and readmissions.Results: Of 100 charts reviewed, 30 patients received a concomitant moderate-to-strong CYP2D6 inhibitor. There were no statistically significant differences between the baseline demographics of the two groups. Change from baseline CINA to discharge did not differ significantly between the Non-2D6 group and the 2D6 group (-4.0 ± 3.83 and -4.5 ± 4.48 respectively; p = 0.606). The average CINA score for nausea and vomiting was significantly higher in the Non-2D6 group compared to the 2D6 group (0.34 ± 0.35 and 0.18 ± 0.33 respectively; p = 0.019). Otherwise there were no significant differences found in any secondary outcomes.Conclusions: Based on these results, moderate-to-strong CYP2D6 inhibitors do not appear to have a significant impact on the withdrawal course for patients treated with a high-dose tramadol taper.

Abstract
The increase in the prescription of opioid medications has resulted in a wildfire of misuse of opioids, both for medical and non-medical reasons, with over 1.7 million people in the United States (US) suffering from distinct disorders owing to opioid use. While various medications, such as methadone, buprenorphine, and naloxone, among others, have been used in treating opioid withdrawal symptoms, concerns of the potential abuse of these drugs, the cost of procurement, legislations, and prescription policies have risen. In recent times, tramadol has been considered a viable replacement for some of these treatment regimes. Tramadol is a synthetic analgesic that acts centrally, possessing opioid-like effects due to the binding of its metabolite with the mu (µ)-opioid receptor, yet with low potential for abuse. Several clinical studies conducted in the past ten years have identified the effects of tramadol in opioid withdrawal cases. The results showed that it exhibits better efficacy and tolerance with fewer side effects in specific clinical scenarios as compared to existing available detox management. We aim to examine the properties of tramadol in opioid withdrawal through this systematic review of clinical studies on humans.

Abstract
The purpose of the study was to describe patient outcomes with a 3-day tramadol taper for acute opioid withdrawal on the detoxification unit at Summa Health System. The primary endpoint was the change in Clinical Institute Narcotic Assessment (CINA) score from the start of the taper until completion or discharge. Secondary endpoints were length of stay, use of adjuvant medications, taper completion rates, highest CINA score, adverse events, and 30-day readmission rates. A retrospective, quality improvement, cohort study was performed describing outcomes of opioid dependent patients in acute withdrawal admitted on the detoxification unit between September 2014 and September 2016 receiving the 3-day tramadol taper. All patients ≥18 years of age admitted for opioid dependence were included. Pregnant patients were excluded. Forty-five patients were included in the analysis. Patient ages ranged from 18-67 and 25 (55.6%) were male. The full taper was completed in 67.7% of admissions and 75.8% of patients were discharged by the physician. There was a statistically significant change of the pre-taper score compared to the score at completion or discharge in the per protocol group (-1.58, p = 0.010). There were no reported seizures or falls. The 3-day tramadol taper proved to be safe and effective therapy for treating acute opioid withdrawal. In the Summa Health System detoxification unit, patients treated with a 3-day tramadol taper for acute opioid withdrawal had their pre-taper CINA scores reduced by over 25% at the completion of the taper or discharge.

Abstract
Opioids are one of the most common illicit psychoactive substances being used in India. In fact, opioid use disorders are the most common disorder presenting to the substance use disorder treatment centers across the country. Effective and evidence-based interventions are available for management of opioid use disorders. However, the treatment for opioid use disorders remains difficult to access for most of those in need in India. The current article presents the literature on the use of tramadol for the management of opioid use disorders. It also makes recommendations on the use of tramadol for the management of opioid use disorders. Tramadol offers a viable alternative to the existing options for the management of opioid use disorders. It has been found effective when used for this indication. It offers certain major advantages such as easy and wide availability and low abuse liability. It offers a good option to expand the treatment services for opioid use disorders across the country.

Abstract
Tramadol is commonly prescribed for pain control because it presents a lower risk for addiction and respiratory depression compared to other opioids. However, tramadol's serotonin and norepinephrine reuptake inhibitory effects result in a unique adverse effect profile. Two such adverse events are serotonin syndrome and seizures. The prevalence of tramadol-induced serotonin syndrome and seizures is modest in the general population, but if left untreated, the morbidity and mortality can be high; therefore, prompt recognition and management is essential. Various risk factors such as medical comorbidities, use or abuse of supratherapeutic doses of tramadol, and concomitant administration of proconvulsant serotonergic cytochrome P-450 inhibitors will help clinicians identify individuals at an elevated risk for serotonin toxicity and seizures. Serotonin syndrome and seizures can be effectively treated by administering benzodiazepines, providing supportive care, and discontinuing tramadol and other contributing agents. Cyproheptadine should be administered in moderate to severe cases of serotonin syndrome. Our objective is to summarize the literature on the pharmacology, epidemiology, risk factors, clinical presentations, and evidence-based management of tramadol-related seizures and serotonin syndrome.

Abstract
IMPORTANCE Opioid use disorder (OUD) is a significant public health problem. Supervised withdrawal (ie, detoxification) from opioids using clonidine or buprenorphine hydrochloride is a widely used treatment. OBJECTIVE To evaluate whether tramadol hydrochloride extended-release (ER), an approved analgesic with opioid and nonopioid mechanisms of action and low abuse potential, is effective for use in supervised withdrawal settings. DESIGN, SETTING, AND PARTICIPANTS A randomized clinical trial was conducted in a residential research setting with 103 participants with OUD. Participants' treatment was stabilized with morphine, 30 mg, administered subcutaneously 4 times daily. A 7-day taper using clonidine (n = 36), tramadol ER (n = 36), or buprenorphine (n = 31) was then instituted, and patients were crossed-over to double-blind placebo during a post-taper period. The study was conducted from October 25, 2010, to June 23, 2015. MAIN OUTCOMES AND MEASURES Retention, withdrawal symptom management, concomitant medication utilization, and naltrexone induction. Results were analyzed over time and using area under the curve for the intention-to-treat and completer groups. RESULTS Of the 103 participants, 88 (85.4%) were men and 43 (41.7%) were white; mean (SD) age was 28.9 (10.4) years. Buprenorphine participants (28 [90.3%]) were significantly more likely to be retained at the end of the taper compared with clonidine participants (22 [61.1%]); tramadol ER retention was intermediate and did not differ significantly from that of the other groups (26 [72.2%]; χ2 = 8.5, P = .01). Time-course analyses of withdrawal revealed significant effects of phase (taper, post taper) for the Clinical Opiate Withdrawal Scale (COWS) score (taper mean, 5.19 [SE, .26]; post-taper mean, 3.97 [SE, .23]; F2,170 = 3.6, P = .03) and Subjective Opiate Withdrawal Scale (SOWS) score (taper mean,8.81 [SE, .40]; post-taper mean, 4.14 [SE, .30]; F2,170 = 15.7, P < .001), but no group effects or group × phase interactions. Analyses of area under the curve of SOWS total scores showed significant reductions (F2,159 = 17.7, P < .001) in withdrawal severity between the taper and post-taper periods for clonidine (taper mean, 13.1; post-taper mean, 3.2; P < .001) and tramadol ER (taper mean, 7.4; post-taper mean, 2.8; P = .03), but not buprenorphine (taper mean, 6.4; post-taper mean, 7.4). Use of concomitant medication increased significantly (F2,159 = 30.7, P < .001) from stabilization to taper in the clonidine (stabilization mean, 0.64 [SE, .05]; taper mean, 1.54 [SE, .10]; P < .001) and tramadol ER (stabilization mean, 0.53 [SE, .05]; taper mean, 1.19 [SE, .09]; P = .003) groups and from stabilization to post taper in the buprenorphine group (stabilization mean, 0.46 [SE, .05] post-taper mean, 1.17 [SE, .09]; P = .006), suggesting higher withdrawal for those groups during those periods. Naltrexone initiation was voluntary and the percentage of participants choosing naltrexone therapy within the clonidine (8 [22.2%]), tramadol ER (7 [19.4%]), or buprenorphine (3 [9.7%]) groups did not differ significantly (χ2 = 2.5, P = .29). CONCLUSIONS AND RELEVANCE The results of this trial suggest that tramadol ER is more effective than clonidine and comparable to buprenorphine in reducing opioid withdrawal symptoms during a residential tapering program. Data support further examination of tramadol ER as a method to manage opioid withdrawal symptoms. TRIAL REGISTRATION Clinicaltrials.gov Identifier: NCT01188421.

Abstract
BACKGROUND Substance abuse or drug addiction is one of the most important health issues in every society, which can lead to physical and mental problems. OBJECTIVES This study aimed to compare the efficacy of tramadol plus gabapentin versus methadone use in the treatment of opiate withdrawal. PATIENTS AND METHODS Consenting male subjects who fulfilled the DSM-4 criteria for opiate dependence syndrome (opium, residue, and heroin) were randomly assigned in two groups to receive tramadol plus gabapentin or methadone. Assessment tools were Adjective Rating Scale for Withdrawal (ARSW), Clinical Opiate Withdrawal Scale (COWS) and Visual Analogue craving Scale (VAS). Fifty-nine subjects were enrolled and evaluated on days 1, 2, 3, 4, 6, and 8 during their 10 days of admission. Twenty-nine participants received methadone and the other 30 received tramadol plus gabapentin for their treatment. RESULTS Mean (SD) age of the patients in methadone group and tramadol plus gabapentin group were 33.9 (7.1) and 32.4. (8.1), respectively (P = 0.462). The overall ARSW (P value = 0.263) and COWS (P = 0.862) scores between the two groups were comparable. The differences in the VAS score for craving between the two groups was marginally significant (P = 0.057). The highest VAS score was at the third day of admission in both groups and it was generally higher in methadone group. CONCLUSIONS The severity of withdrawal syndrome in two groups was not significantly different. The craving was higher in the group receiving methadone from the second day of admission even though the usage amount was higher in the tramadol plus gabapentin group. The findings of this study suggest that the combination of tramadol plus gabapentin is an efficient method for opioid detoxification.

Abstract
BACKGROUND Tramadol is an atypical analgesic with monoamine and modest mu opioid agonist activity. The purpose of this study was to evaluate: (1) the efficacy of extended-release (ER) tramadol in treating prescription opioid withdrawal and (2) whether cessation of ER tramadol produces opioid withdrawal. METHODS Prescription opioid users with current opioid dependence and observed withdrawal participated in this inpatient, two-phase double blind, randomized placebo-controlled trial. In Phase 1 (days 1-7), participants were randomly assigned to matched oral placebo or ER tramadol (200 or 600 mg daily). In Phase 2 (days 8-13), all participants underwent double blind crossover to placebo. Breakthrough withdrawal medications were available for all subjects. Enrollment continued until 12 completers/group was achieved. RESULTS Use of breakthrough withdrawal medication differed significantly (p<0.05) among groups in both phases; the 200mg group received the least amount in Phase 1, and the 600 mg group received the most in both phases. In Phase 1, tramadol 200mg produced significantly lower peak ratings than placebo on ratings of insomnia, lacrimation, muscular tension, and sneezing. Only tramadol 600 mg produced miosis in Phase 1. In Phase 2, tramadol 600 mg produced higher peak ratings of rhinorrhea, irritable, depressed, heavy/sluggish, and hot/cold flashes than placebo. There were no serious adverse events and no signal of abuse liability for tramadol. CONCLUSIONS ER tramadol 200mg modestly attenuated opioid withdrawal. Mild opioid withdrawal occurred after cessation of treatment with 600 mg tramadol. These data support the continued investigation of tramadol as a treatment for opioid withdrawal.

Abstract
The aim of this study was to compare the efficacy and safety of tramadol versus methadone for treatment of opiate withdrawal. Seventy patients randomly were assigned in two groups to receive either prescribed methadone (60 mg/day) or tramadol (600 mg/day). The withdrawal syndrome of patients was evaluated before and after rapid opiate detoxification using the Objective Opioid Withdrawal Scale (OOWS). No significant differences existed in overall OOWS scores between two groups (P = 0.11). Dropout rates were similar in both groups. Side effects in the tramadol group were as or less common than in the methadone group, with the exception of perspiration. Tramadol may be as effective as methadone in the control of withdrawal and could be considered as a potential substitute for methadone to manage opioids withdrawal.

Abstract
Tramadol is an unscheduled atypical analgesic that acts as an agonist at μ-opioid receptors and inhibits monoamine reuptake. Tramadol can suppress opioid withdrawal, and chronic administration can produce opioid physical dependence; however, diversion and abuse of tramadol is low. The present study further characterized tramadol in a three-choice discrimination procedure. Nondependent volunteers with active stimulant and opioid use (n = 8) participated in this residential laboratory study. Subjects were trained to discriminate between placebo, hydromorphone (8 mg), and methylphenidate (60 mg), and tests of acquisition confirmed that all volunteers could discriminate between the training drugs. The following drug conditions were then tested during discrimination test sessions: placebo, hydromorphone (4 and 8 mg), methylphenidate (30 and 60 mg), and tramadol (50, 100, 200, and 400 mg). In addition to discrimination measures, which included discrete choice, point distribution, and operant responding, subjective and physiological effects were measured for each test condition. Both doses of hydromorphone and methylphenidate were identified as hydromorphone- and methylphenidate-like, respectively. Lower doses of tramadol were generally identified as placebo, with higher doses (200 and 400 mg) identified as hydromorphone, or opioid-like. The highest dose of tramadol increased ratings on the stimulant scale, but was not significantly identified as methylphenidate-like. Tramadol did not significantly increase subjective ratings associated with reinforcement. Taken together, these results extend previous work with tramadol as a potential medication for the treatment of opioid dependence and withdrawal, showing acute doses of tramadol exhibit a profile of effects similar to opioid agonists and may have abuse liability in certain populations.

Abstract
UNLABELLED Opiod dependence is one of the leading psychiatric morbidities in India. The deaddiction centres are meager in number; stigma attached to admission in deaddiction centre is high and most addicts want outpatient treatment so that they do not miss daily wages. Several recent reports stated effectiveness of tramadol in treating opioid withdrawal. This study attempts to compare effectiveness of tramadol with clonidine in opioid withdrawal. METHODOLOGY A total of 60 patients having heroin dependence were selected and out of them 30 got clonidine treatment and the other 30 got tramadol treatment. The clinical opioid withdrawal scale was used. STATISTICAL ANALYSIS "t"-Test was used using SPSS (version-16) for comparison. RESULT Tramadol was more effective in preventing sweating, restlessness, aches, runny nose, GI upset, yawning, anxiety and goose skin. i.e., Tramadol can be used effectively in opioid withdrawal in outpatient based treatment programme.

Abstract
Tramadol is an atypical, mixed mechanism analgesic used to treat moderate to severe pain. Based on evidence that tramadol has relatively low abuse potential and can relieve opioid withdrawal, tramadol may be useful for treating opioid dependence. The purpose of this study was to assess the performance side-effect profile of tramadol. Nine opioid-dependent volunteers completed a performance battery following 5-7 days of subcutaneous morphine (15 mg, 4 times/day) and two doses of oral tramadol (50, 200 mg, 4 times/day) in a within subject cross-over design. Morphine was always the first condition, and the order of the two tramadol doses was randomized and double blind. Performance was significantly worse in the morphine condition relative to one or both tramadol doses on measures of psychomotor speed/coordination (circular lights task), psychomotor speed/pattern recognition (DSST speed measure) and psychomotor speed/set shifting (trail-making tasks). There were no significant differences among conditions in DSST accuracy, simple reaction time, divided attention, working memory, episodic memory, metamemory, or time estimation. Neither tramadol dose was associated with worse performance than morphine on any measure. Although practice sessions were conducted prior to the first session to reduce order effects, the possibility that residual practice effects contributed to the differences between tramadol and morphine cannot be ruled out. The high tramadol dose produced worse performance than the low dose only on the balance measure. These findings suggest that tramadol is generally a safe medication with respect to cognitive and psychomotor measures and support tramadol's further evaluation as an opioid-dependence treatment.

Abstract
RATIONALE Tramadol is an atypical, mixed-mechanism analgesic involving both opioid and catecholamine processes that appears to have low abuse potential and may be useful as a treatment for opioid dependence. OBJECTIVES The current study assessed the level of physical dependence and opioid blockade efficacy produced by daily maintenance on oral tramadol. METHODS Nine residential opioid-dependent adults were maintained on two doses of daily oral tramadol (200 and 800 mg) for approximately 4-week intervals in a randomized, double-blind, crossover design. The acute effects of intramuscular placebo, naloxone (0.25, 0.5, and 1.0 mg), and hydromorphone (1.5, 3.0, and 6.0 mg) were tested under double-blind, randomized conditions. Outcomes included observer- and subject-rated measures and physiologic indices. RESULTS Challenge doses of naloxone resulted in significantly higher mean peak withdrawal scores compared to placebo. Withdrawal intensity from naloxone was generally greater during 800 versus 200 mg/day tramadol maintenance. Mean peak ratings of agonist effects were elevated at higher hydromorphone challenge doses, but did not differ significantly between tramadol doses. Physiologic measures were generally affected by challenge conditions in a dose-dependent manner, with few differences between tramadol maintenance dose conditions. CONCLUSIONS Chronic tramadol administration produces dose-related opioid physical dependence, without producing dose-related attenuation of agonist challenge effects. Tramadol may be a useful treatment for patients with low levels of opioid dependence or as a treatment for withdrawal during opioid detoxification, but does not appear to be effective as a maintenance medication due to a lack of opioid cross-tolerance.

Abstract
RATIONALE Tramadol is in an unscheduled atypical analgesic with low rates of diversion and abuse and mixed pharmacologic actions, including modest opioid agonist activity. OBJECTIVES The purpose of the current study was to characterize the opioid withdrawal suppression efficacy of oral tramadol. MATERIALS AND METHODS Residential, opioid-dependent adults (n = 10) were maintained on morphine (15 mg subcutaneously, quad in diem) for approximately 6 weeks. Spontaneous opioid withdrawal was produced by substituting placebo for scheduled morphine doses 17.5 h before experimental sessions that occurred twice weekly. The acute effects of placebo, tramadol (50, 100, 200, and 400 mg orally), naloxone (0.1 and 0.2 mg intramuscularly [IM]), and morphine (15 and 30 mg IM) were tested under double-blind, double-dummy, randomized conditions. Outcomes included observer- and subject-rated measures, physiologic indices, and psychomotor/cognitive task performance. RESULTS Naloxone and morphine produced prototypic opioid antagonist and agonist effects, respectively. Tramadol 50 and 100 mg produced effects most similar to placebo. Tramadol 200 and 400 mg initially produced significant dose-related increases in ratings of "bad effects" and "feel sick," followed by evidence of opioid withdrawal suppression. Tramadol did not produce significant increases on measures of positive drug effects nor any clinically significant physiologic changes. CONCLUSIONS Tramadol 200 and 400 mg show evidence of opioid withdrawal suppression without significant observer- and subject-rated opioid agonist effects. The profile of action did not suggest a high risk for tramadol abuse in opioid dependent individuals. Tramadol may be a useful medication for treating opioid withdrawal.

Abstract
Tramadol is thought to induce analgesia via both opioid and non-opioid pathways, although the precise mechanisms remain to be elucidated. In this study, we investigated the roles of the mu-opioid receptor (MOP) in analgesic and rewarding effects of tramadol by using MOP knockout (KO) mice. Tramadol-induced antinociception, assessed by hot-plate and tail-flick tests, was significantly reduced in heterozygous and homozygous MOP-KO mice when compared with that in wild-type mice. Interestingly, however, tramadol retained its ability to induce significant antinociception in homozygous MOP-KO mice. The tramadol-induced antinociception remaining in homozygous MOP-KO mice was not significantly affected by methysergide, a serotonin receptor antagonist, but was partially blocked by yohimbine, an adrenaline alpha2 receptor antagonist, and both naloxone, a non-selective opioid receptor antagonist, and yohimbine. In addition, antinociceptive effects of an active tramadol metabolite M1 were abolished or remarkably reduced in MOP-KO mice. On the other hand, neither wild-type nor homozygous MOP-KO mice showed significant place preference for tramadol in a conditioned place preference test, although there were slight tendencies toward preference in wild-type mice and avoidance in homozygous MOP-KO mice. These results strongly support the idea suggested in the previous pharmacological studies that MOP and the adrenaline alpha2 receptor mediate most of the analgesic properties of tramadol.

Abstract
The subjective, behavioral, and physiologic effects of racemic tramadol, an analgesic with low abuse liability and dual mu-opioid agonist and monoamine reuptake actions, were evaluated in 2 clinical pharmacology studies in dependent opioid abusers. In the withdrawal precipitation study, participants (N = 8) were maintained on methadone 60 mg/day orally and challenged with intramuscular tramadol, hydromorphone, naloxone, and placebo 20 hr after methadone administration. In the withdrawal suppression study, participants (N = 6) were maintained on hydromorphone given orally 10 mg 4 times daily, and spontaneous opioid withdrawal was produced by withholding doses for 23 hr. During the experimentally induced withdrawal, oral tramadol, hydromorphone, naltrexone, and placebo were given. In both studies a comprehensive panel of participant-rated, observer-rated, and physiologic measures were collected. In both studies, naloxone and naltrexone significantly increased measures of opioid withdrawal, whereas tramadol showed no discernible antagonist effects. In contrast, tramadol's pattern of effects was more similar to that of hydromorphone and suggestive of mild opioid-agonist effects (withdrawal suppression), though not to a statistically significant degree.

Abstract
Buprenorphine-naloxone is an office-based opioid agonist released in 2003 in the United States for the maintenance of heroin- and other opioid-dependent patients. Concern has been raised that the medication will distract or otherwise inhibit patients from participating in a holistic recovery program or abstinence-based counseling. Using a retrospective chart review, the first thirty opioid-dependent patients induced on buprenorphine maintenance therapy in an inpatient detoxification unit were compared to thirty age- and gender-matched patients who underwent detoxification (with a tramadol taper) and referral to intensive outpatient treatment. The clinical outcomes were a comparison of completion rates for an intensive outpatient program (IOP) and retention in treatment after twelve weeks of aftercare therapy. Patients induced on buprenorphine maintenance over three days had similar relief of withdrawal symptoms to patients detoxified from opioids over five days with tramadol. Patients maintained on buprenorphine had a markedly increased initiation of IOP and remained in outpatient treatment longer than patients who were detoxified (8.5 wks vs. 0.4 wks, p < 0.001). This study indicates that induction and maintenance on buprenorphine may be more effective than detoxification for engaging and retaining patients in abstinence-based comprehensive outpatient addiction treatment.
