More » in early october 2002, the fda announced the approval of subutex buprenorphine hydrochloride ; and suboxone tablets buprenorphine hydrochloride and naloxone hydrochloride ; for the treatment of opiate dependence.
Hours 305.38 and 311.38. Following cessation of dosing, the child was monitored for 4 days in the transitional nursery without further signs of withdrawal and the child was discharged to home with his mother. The total length of treatment was 13 days and the total length of stay was 18 days. AN 07 The baby is a term infant born 11 18 2005 of a mother maintained on methadone 155 mg day. The mother denied peripartum use of benzodiazepines and a number of urine drug screens in the months prior to delivery demonstrated only methadone positivity. On 11 21 2005 the infant had symptoms of opiate withdrawal and was randomized to treatment with buprenorphine 12.3 ugm. The dose of buprenorphine was gradually increased over the following days to a dose of 25.4 ugm q 8 hours on morning of 11 24 2005. Four rescue doses were administered up to this point, the last of which the evening of 11 23 05. There was a better control of withdrawal symptoms throughout the day of 11 24 without evidence of respiratory depression. This was also the first day that the infant nippled all her feeds. Immediately following the third dose of 25.4 ugm at 19: 30 78.5 hours after the initial dose ; on 11 24 the infant had tonic-clonic seizures that required the use of lorazepam and phenobarbital. Therapy with buprenorphine was halted. Total buprenorphine dose in the 24 hours prior to the event was 86.9 ugm including the 19: 30 dose of 11 24 Neurologic exam was non-focal. Extensive work-up for a cause of seizures was negative. Abstinence syndrome was treated with NOS and Phenobarbital. On follow-up, development and neurologic exam are normal. Review by the DSMB determined that buprenorphine likely did not cause the seizures, and the researcher has been re-approved by the IRB, and is now again enrolling subjects. Pharmacokinetic Results Pharmacokinetic samples were obtained by heel stick blood collection for AN 06 and 07. Dose is presented in units of nanograms ng ; . With the exception of an outlier value of 3.68 ng mL for the second blood draw of AN 06, values for buprenorphine were less than 0.54 ng mL. Interpretation Clinical response to buprenorphine treatment Both AN 06 and 07 demonstrated good clinical responses to buprenorphine, when gauged by the Finnegan NAS scores. Both required rapid up-titration of dose based upon intermittent, elevated symptom scores in the first several days of treatment. AN 06 was able to reach a plateau dose with good therapeutic control. The child had a short duration of treatment relative to average morphine duration of treatment and had an inpatient length of stay well below the average for TJUH 53 and 58 days, respectively ; for this diagnosis. AN 07 had stability of symptoms the day of the seizure and had not required up titration or rescue dose in the 24 hours prior to the event. Therapeutic range of buprenorphine In adults, maximum buprenorphine solution concentrations are obtained approximately one hour after the dose, with a standard 4 mg dose generating a Cmax of 3.6 + - 1.5 ; ng mL. Relief from abstinence symptoms is estimated at concentrations of 0.7 ng mL, while the physiologic effects of buprenorphine solution administered sublingually are noted to plateau at doses between 4 and 8 mg. Barrett reported mean concentrations of 4.3 + - 2.6 ; ng ml in premature infants.

By Jenifer Blasinsky, PharmD, Pharmacy Department Sublingual buprenorphine tablets have recently come on the market for the treatment of opioid dependence. Previously only the parenteral form of buprenorphine was available for pain management under the brand name of Buprenex. Buprenorphine sublingual tablets are available alone Subutex ; and with naloxone Suboxone ; . Prescribing Buprenorphine As a schedule III narcotic, buprenorphine will be subject to fewer prescribing restrictions than methadone, which is a schedule II narcotic. However, under the Drug Addiction Treatment Act of 2000 DATA 2000 ; , the use of buprenorphine in the treatment of opioid dependence is limited to physicians who meet certain qualifying requirements. Prescribers must register with the Substance Abuse and Mental Health Services Administration dpt.samhsa.gov ; . In the hospital setting, the regulations for prescribing are the same as for those in the office setting. The exception is for those patients who are admitted for a primary medical problem other than opioid addiction. In this case, any physician, including residents, may prescribe buprenorphine to prevent withdrawal. In all other cases, the physician must be certified to prescribe sublingual buprenorphine. Please note: As of May 2005, buprenorphine was not on Formulary at West Penn Hospital. Pharmacology Buprenorphine is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor. This means that, although buprenorphine is an opioid, and thus can produce typical opioid effects and side effects such as euphoria and respiratory depression, its maximal effects are less than those of full agonists like heroin and methadone. At low doses, buprenorphine produces sufficient agonist effects to enable opioid-addicted individuals to discontinue the misuse of opioids such as heroin ; without experiencing withdrawal symptoms. The agonist effects of buprenorphine increase linearly with increasing doses of the drug until at moderate doses they reach a plateau and no longer continue to increase with further increases in dose this is known as the "ceiling effect". Thus, buprenorphine carries a lower risk of abuse, addiction, and side effects compared to full opioid agonists. In fact, in high doses and under certain circumstances, buprenorphine can actually block the effects of full opioid agonists and can precipitate withdrawal symptoms if administered to an opioid-addicted individual while a full agonist is in the bloodstream. Buprenorphine has poor oral bioavailability and must be administered by the sublingual route. Tablets are placed under the tongue until dissolved. Buprenorphine tablets should not be swallowed. Dosage The maximal effects of buprenorphine in the form of sublingual tablets appear to occur in the dose range of 16 to mg. Higher doses are unlikely to produce greater effects. Side Effects Side effects of buprenorphine are similar to those of other opioids and include nausea, vomiting, and constipation. Respiratory depression is less likely to occur with buprenorphine or buprenorphine naloxone ; overdose than with overdose of other opioids. Abuse Potential Because of its opioid agonist effects, buprenorphine can be abused, particularly by individuals who are not physically addicted to opioids. Naloxone is added to buprenorphine to decrease the likelihood of diversion and abuse of the combination product. Sublingual buprenorphine has moderate bioavailability, while sublingual naloxone has poor bioavailability. Thus, when the buprenorphine naloxone tablet is take in sublingual form, the buprenorphine opioid agonist effect predominates, and the naloxone does not precipitate opioid withdrawal in the opioid-addicted user. On the other hand, naloxone via the parenteral route has good bioavailability. Thus, if the sublingual buprenorphine naloxone tablets are crushed and injected by an opioid-addicted individual, the naloxone effect predominates and can precipitate the opioid withdrawal syndrome. Professional Paradigms thanks Ms. Blasinsky for writing this article to add to nurses' knowledge about buprenorphine. She may be reached at 412-578-1653 with any questions about this or other medications for West Penn Hospital patients.

All NCAA-sponsored regionals must obtain referees from the local area that have attended or viewed the official NCAA wrestling rules clinic in the fall of 2005. The tournament directors are responsible for the acquisition of referees, subject to the approval of the division committee chair. The number of referees is determined by the application of the formula of 1 referees per mat. If an uneven number of mats is being used, the number of referees shall be rounded up to the next whole number. Please note that if only two mats are used for the competition, then four officials may be assigned. Each referee is paid a per-session fee. The 2006 fee is 0. In addition, all officials will receive travel expenses based on 43 cents per mile. Referees will receive a per diem for meals and incidentals for each day of the regionals, beginning with the day of arrival and ending with the day of departure. It is required that officials be paid not later than 10 days after the competition.

4.2.7 Perforation of the heart or lungs The use of a subclavian approach to gain venous access for the procedure allows for the possibility that the operator will perforate a lung and cause a pneumothorax. Similarly the insertion of an endocardial lead via the superior or inferior ; vena cava means that the procedure may accidentally result in perforation of the right ventricle of the heart. In the few studies that have commented on these potential problems the incidence of either complication appears to be very low, and usually below 1.
Patients who are unconscious or vomiting 2 ; . Despite all these advantages, a timely warning to formulators was also issued in 1987 2 ; , `TDD is not a subject which can be approached simplistically without a thorough understanding of the physicochemical and biological parameters of percutaneous absorption. Researchers who attempt TDD without appreciating this fact do so at their peril.' As with the other routes of drug delivery, transport across the skin is also associated with several disadvantages, the main drawback being that not all compounds are suitable candidates 94 ; . Since the inception of TDD there has only been a very limited number of products launched onto the market 3 ; and the considerable research and development expense in the transdermal product development and skin research field to bring more TDD products to the market has been slow 37 ; . There are various reasons for this but the most likely is the rate-limiting factor of the skin 1 ; . The rate-limiting resistance resides in the SC 26 ; . The skin is a very effective barrier to the ingress of materials, allowing only small quantities of a drug to penetrate over a period of a day 3, 9 ; . A typical drug that is incorporated into a dermal drug delivery system will exhibit a bioavailability of only a few percent and therefore the active has to have a very high potency. For transdermal delivery, as a rule of thumb, the maximum daily dose that can permeate the skin is of the order of a few milligrams. This further underscores the need for high potency drugs 3 ; . As evidence of this, all of the drugs presently administered across the skin share constraining characteristics such as low molecular mass 500 Da ; , high lipophilicity log P in the range of 1 to low melting point 200C ; and high potency dose is less than 50 mg per day ; 1, 2, 4, ; . The smallest drug molecule presently formulated in a patch is nicotine 162 Da ; and the largest is oxybutinin 359 Da ; . Opening the transdermal route to large hydrophilic drugs is one of the major challenges in the field of TDD 8 ; . The required high potency can also mean that the drug has a high potential to be toxic to the skin causing irritation and or sensitisation 1, 3, 7 ; . If the barrier function of the skin is compromised in any way, some of the matrix-type delivery devices can deliver more of the active than necessary and the transdermal equivalent of `dose dumping' can occur 3 ; . Elevated drug concentrations can be attained if a transdermal system is repeatedly placed on the old site and this can lead to the possibility of enhanced skin toxicity. Other difficulties encountered with TDD are the variability in percutaneous absorption, the precision of dosing, the reservoir capacity of the skin, heterogeneity and inducibility of the skin in turnover and metabolism, inadequate and busulfan.

Unfortunately, traumatic diaphragmatic hernia is often a difficult diagnosis to make. Roentgenographic findings in clude the presence of an abdominal organ above the dia phragm, elevation of the hemidiaphragm or loss of its normal contour, pleural effusion, basilar atelectasis, contralateral mediastinal shift, and pneumothorax. * Our case illustrates that pneumothorax can be the pre senting complication of traumatic diaphragmatic hernia. However, there appear to be four different presentations of traumatic diaphragmatic hernia with strangulated stomach that can mimic or produce pneumothorax: 1 ; gastric distention simulating pneumothorax; 2 ; tension gastrothorax; 3 ; pneumothorax secondary to gastropleural fistula; and 4 ; tension pneumothorax due to gastropleural fistula. A relatively common roentgenographic manifestation of a herniated stomach is a lucency above the diaphragm, as was initially present in our patient. Because the gastric air bubble can be mistaken for pneumothorax, thoracentesis or chest tube insertion may be performed, carrying the risk of gastric perforation with spillage of gastric contents into the pleural space. Initial intervention should consist of insertion of a nasogastric tube. This simple maneuver not only serves as a diagnostic aid, but it will also decompress the distended stomach. Tension gastrothorax, an unusual manifestation of a her niated stomach, occurs when a large portion of the stomach herniates into the thorax and subsequently distends with air. The dilated stomach causes the trachea and mediastinum to shift and tension physiology to ensue." As with a simple herniated stomach, thoracentesis and chest tube insertion carry the risk of iatrogenic gastropleural fistula with contam ination of the pleural cavity by gastric contents.46 Alternatively, as our case illustrates, a herniated stomach may perforate spontaneously, creating a pneumothorax with contamination of the pleural space by gastric contents. There are data to suggest that once a stomach is incarcerated, it may perforate rapidly. Johnston and Twente1" postulated that.

Burned out, had been heading to Kazimiyah, which is home to the most important Shiite mosque in the capital. Elsewhere, a bomb hidden under a concrete barrier exploded as workers were paving a street in an intersection in a predominantly Shiite area in eastern Baghdad, killing one worker and wounding two others, police said. Authorities said Iraqi soldiers supported by U.S. aircraft fought all day Sunday with a large group of insurgents in the Zaraq area, about 12 miles northeast of the Shiite holy city of Najaf. Provincial Gov. Assad Sultan Abu Kilel said the assault was launched because the insurgents planned to attack Shiite pilgrims and clerics during ceremonies marking Ashoura. Officials were unclear about the religious affiliation of the militants. Although Sunni Arabs have been the main force behind insurgent groups, there are a number of Shiite militant and splinter groups that have clashed from time to time with the government. Iraqi soldiers attacked at dawn and militants hiding in orchards fought back with automatic weapons, sniper rifles and rockets, the governor said. He said the insurgents were members of a previously unknown group called the Army of Heaven. "They are well-equipped and they even have anti-aircraft missiles, " the governor said. "They are backed by some locals" loyal to ousted dictator Saddam Hussein. The mortar attacks and bombings appeared to be part of the sectarian reprisal killings that have pushed Iraq into civil warfare over the past year, violence that President Bush hopes to quell by sending up to 21, 500 more American soldiers to Baghdad and surrounding areas. U.S. officials have long accused al-Qaida in Iraq, a Sunni Muslim group, of fanning sectarian hatreds by staging vicious attacks on Shiite civilians. Revenge killings have surged since the bombing of a Shiite shrine in the largely Sunni city of Samarra last Feb. 22.

Buprenorphine is being tested in settings and in populations in which it has seldom been previously prescribed. Early findings suggest high acceptability by both patients and providers in these clinical research settings. Buprenorphine could find utility in numerous other settings, and the CTN has the capability to examine its use in these venues.

Dependence 51 ; . Another approach is to use buspirone in the treatment of acute opioid withdrawal, the assumption being that a decrease in serotonergic neurotransmission may be involved in opioid withdrawal symptoms. Initial results found buspirone to be as effective as methadone tapering in alleviating withdrawal symptoms 52 ; . However, more studies are necessary before firm conclusions can be drawn regarding the efficacy of these new detoxification strategies. Although methadone or buprenorphine maintenance is the preferred treatment for pregnant women with heroine dependency 5355 ; , naltrexone-assisted detoxification may be an option for women who are unable to stabilize on methadone or buprenorphine and continue to use street drugs. In a series of 18 cases with detoxifications in all 3 trimesters, no neonatal, maternal, or obstetric complications were observed following naltrexone detoxification 56 ; . Relapse Prevention Traditional relapse-prevention programs were limited to long-term inpatient treatments that were intended to last at least 9 months and that often used the therapeutic community format. In many countries, this model has been replaced by shorter inpatient treatments generally lasting less than 6 weeks. The positive effects of both long-term and short-term programs are, however, rather limited. In a 3-month follow-up of 242 opioid-dependent patients in residential treatment in the National Treatment Outcome Research Study, 34% of the patients relapsed to heroin use within 3 days, 45% within 7 days, 50% within 14 days, and 60% within 90 days. According to the authors, the results of this study highlight the need to provide aftercare services to help patients maintain the gains achieved during treatment and to avoid the high risk of relapse at this time 57 ; . One possibility to reduce the risk of relapse to illegal opioid use is long-term prescription of an opioid antagonist such as naltrexone, the "model anti-craving medication" 58 ; . The first obstacle involved in this strategy is the high dropout rate during detoxification, which results in highly selective patient samples in most of the naltrexone maintenance studies 59 ; . In metaanalytical review, retention was found to be the most important predictor for the effect of naltrexone in treating opioid dependence, and the authors therefore proposed to add counselling 60 ; or contingency management 61 ; to naltrexone maintenance treatment. Another important option to improve retention is the use of a sustained release depot formulation of naltrexone. A recent study of this formulation for the treatment of opioid dependence found 60% to 68% retention after 2 months 62 ; . However, the study sample was small, and no direct comparison with oral naltrexone was provided. Therefore, the potential advantages should regarded as promising but not proven and buprenorphine.

By Chris Kelly SAMHSA CSAT held a "Buprenorphine Stakeholders Meeting" on July 26. 2002, in Bethesda, MD. The big question, "When is the FDA going to approve buprenorphine for opiate addiction treatment", was, unfortunately, not answered. Although there were representatives from the FDA, Schering Plough, Reckitt and Coleman, and the DEA at this meeting, no one would say "when" this livesaving and critical medication will be approved. That said, there were some interesting developments discussed. The first is that CSAT and the DEA have "certified" 170 doctors to prescribe buprenorphine so far. The Drug Abuse Treatment Act DATA ; enacted in 2000 amends the Controlled Substances Act CSA ; to allow qualified physicians to apply for waivers of the Narcotic Treatment Act and the CSA registration so that they may dispense or prescribe certain Schedule III, IV and V controlled substances specifically approved by the FDA for opiate addiction treatment. Although there are no FDA-approved medications available at this time, these 170 doctors will be able to prescribe buprenorphine the day the FDA approves the medication. Additional information on DATA, including the Standard Notification Form which physicians must complete to become b u p ine provider s , may be found at buprenorphine.samhsa.gov. If readers know of any doctors who would be interested in adding opiate addiction treatment to their practices, we urge you to visit this website. The Federation of State Medical Boards has also developed Model Policy Guidelines for Opioid Addiction Treatment in the Medical Office, available at the FSMB website at fsmb . Under the terms of DATA, these physicians must be "qualified." There are several ways for doctors to demonstrate that they are qualified: ASAM, AOA certification, participation in a clinical trial, eight-hour training provided by ASAM, AAAP, AOAAM, APA, etc. There are also online courses available. Approximately 2, 000 U.S. doctors have taken the courses, although they have not yet submitted the required Standard Notification Form to CSAT. One other restriction of DATA is that these physicians will also certify that they will treat no more than 30 opiate-addicted patients at one time. The DEA will be responsible for monitoring this 30-patient limit. In addition, certified doctors will get a "buprenorphine specific" DEA number which must be used on all buprenorphine prescriptions. DEA field officers will include two certified buprenorphine practitioners in each of their quarterly work.
