Usage of opium has a long history of remedy intentions in many parts of the East especially Asia^[1-3]. Opium derivatives, mainly buprenorphine has been under extensive research for the treatment of opioid use disorders^[4]. Probing for the treatment of opium addiction, contrasting methadone with buprenorphine, disclosed that buprenorphine is more positive than methadone^[5-7]. Furthermore, studies illuminates that efficacy of 8 mg buprenorphine is parallel to 60 methadone^[8].

  Buprenorphine, a medication with mixed agonist-antagonist characteristics, has been beneath rating as a potential detoxification drug for the management of opioids addiction. Evaluations have distinguished buprenorphine as an agonist of mu receptor, and as a strong K-receptor antagonist^[9-12]. A medication with partial agonist property is presented as a compound for which even at total saturation of the receptor system their effect is already less than the maximal achievement preparable with full agonists. Thus buprenorphine has less intrinsic activity at preceptors comparing to full agonists^[13-15]. In man, buprenorphine elicit typical long duration effects of mu opioid agonist, including analgesia, euphoria, pupillary constriction and sedation.

  Moreover, a ceiling on the buprenorphine respiratory depressant and euphoric effects would produce more safety in clinical practice. Since respiratory depression is the main lethal adverse effect of opioids, hence it would be highly favorable to have a forceful opioid with a lower potential for making this side effect^[14-16].

  According to the new information, medical and mental disease are going upward universally^[17-30].

  Focusing on mental disorders, substance use disorders, have been contemplated as a developing dilemma^[31]. Concentrating on the published research works, opioids jointed disorders and stimulants allied problems have resulted more admissions to the psychiatric centers^[32-40].

  Now a days, buprenorphine is mainly used for the treatment of opioid withdrawal symptoms[41].
  We examined three high doses of buprenorphine for the management of chronic opium dependence.

  We ourselves compose a Visual Analogue Scale (VAS) and checked it empirically for reliability and validity to rate and categorize the opium withdrawals including pain and craving, limiting from 0 to 10 (0 means no craving or pain at all and 10 means severe temptation and craving all the time). Besides we constructed the subject exactly about marking.
Validated and reliable Craving Scale: 0-1-2-3-4-5-6-7-8-9-10^[31,32].

Patient picture
  We would like to present our patient with heavy and prolonged dependency to opium who responded successfully to three high doses of buprenorphine. EA was a 34-year old single, unemployed with university education. He resided in the south of Iran, capital city of Shiraz, province of Fars with his parents. He commenced smoking tobacco and opium at age of 19. EA stepwise increased the dosage of opium so that he became dependent to opium. He gave history of occasional abuse of clonazepam and methadone. Since 10 years prior to admission he little by little developed anxiety, restlessness, obsessions isolation, hopelessness and depressed mood. He gave history of 20 short times of opium abstinences. He reported history of psychiatric disorders in his sister. He referred to the outpatient clinic of Ebnesina psychiatric hospital and was hospitalized in dual diagnosis ward.

  During complete psychiatric interview and precise examination, he had restlessness, agitation, anxiety, depression and isolation. Regarding comprehensive and detailed physical and neurological examinations we did not find any pathology. Urine toxicology test (Thin Layer Chromatography, TLC) was positive for morphine and methadone. Tests of serology for viral markers (HIV, HCV and HB Ag) did not demonstrate abnormal findings.

  Based on medical, psychiatric, and substance use history and DSM-5 criteria, he was diagnosed as “opioid induced depressive disorder with severe use disorder. At the time of admission and based on his symptoms we administered olanzapine 20 mg, trazodone 50 mg and venlafaxine 150 mg per day to treat depression, anxiety and insomnia.

  Since he was suffering from significant pain and craving, so in the 2^nd day of admission he received one dose of 32 mg sublingual buprenorphine. Moreover, one day later, in the 3^rd day of admission, he still was complaining of withdrawal symptoms so, we gave him a dose of 96 mg buprenorphine. He was pretty good till 5^th day of hospital, but developed pain and craving. Therefore, he received one dose of 72 mg buprenorphine. Few hours later his symptoms disappeared. Since he did not report any symptoms of withdrawal, he was discharged nine days later.

  The mean scores for opioid (opium) withdrawal pain for 13 days of hospital admission were 1 & 0 & 1 & 1 & 2 & 0 & 0 & 0, & 0 & 0 & 0 & 0 & 0, respectively.

  With regards to the precise interview, monitoring and scoring (3 times a day) for opium withdrawal pain, EA experienced and reported a descending level of pain after receiving three doses (32 mg, 96 & 72 mg) of buprenorphine.

  The mean scores of opioid (opium) withdrawal craving for 13 days of hospital admission were 3 & 7 & 8 & 3 & 6 & 0 & 0 & 0, & 0 & 0 & 0 & 0 & 0, respectively. After 13 days of hospitalization he was discharged without having any withdrawal temptation and pain.

Discussion and Conclusion

  We could not find any published study with three high doses of buprenorphine. This work demonstrated that three high doses of buprenorphine (32, 72 and 96 mg) could be adequate for opium withdrawal symptoms treatment. Hence, this report could be an important addition to the literature. We reached to this fact that administration of sublingual buprenorphine in high dose looks tolerable and helpful. Farther investigation should be of interest as high buprenorphine doses are clinically getting more popular. We concluded that three consecutive high doses of buprenorphine can be adequate in the treatment of severe opioids withdrawal symptoms. It seems that administering three high doses of buprenorphine is more powerful than daily buprenorphine administration for a long time.
