Confidence grows The subpoena brought a windfall of information. The significance of the Tennessee case started to become clear. The DEA learned that in the six weeks after the Tennessee task force alerted Mallinckrodt to the drugs found in the sting operation, the company had shipped another 2.

The DEA also discovered that Sunrise, over an month period, had sent at least 92, tablets to Schultz, the Delray Beach doctor who prescribed the pills found in Tennessee.

In one day, he had prescribed 1, tablets to one patient. Barry Schultz, a doctor who ran a medical clinic in Delray Beach, Fla. He was charged with drug trafficking and manslaughter after one of his patients died of an overdose. Under pressure from the DEA, Sunrise had surrendered its license to distribute narcotics.

Schultz was later convicted and sentenced to 25 years in prison. Investigators documented scores of alleged violations, including the failure to secure narcotics, to keep accurate records or to document transfers of drugs, according to a confidential memo obtained by The Post. Levorphanol Levorphanol is the only commercially available opioid agonist of the morphinan series and the levo-enantiomer of dextrorphan, a potent NMDA receptor antagonist [].

Levorphanol was first synthesized more than 40 years ago as an alternative to morphine, and it produces effects very similar to morphine, with greater potency. Analgesia is produced by activity as a mu, delta, and kappa opioid receptor agonist, NMDA receptor antagonist, and norepinephrine and serotonin reuptake inhibitor.

The NMDA receptor antagonist potency of levorphanol is equivalent to ketamine and superior to methadone [49]. Single-dose analgesic duration is 6 to 8 hours, and the elimination half-life is 11 hours. This increases the potential for drug accumulation, and patients should be observed for toxicity during the initial two to five days.

Initiate dosing every four hours, and every six to eight hours when steady state is reached after one to two weeks [15, ]. During the s, levorphanol fell into disuse with the introduction and aggressive marketing of ER forms of morphine, oxycodone, and fentanyl. Renewed interest in this drug was prompted by recognition that many patients with neuropathic pain do not obtain pain control with standard full-agonist opioids. Levorphanol shows promise in treating neuropathic pain, severe pain in hospice patients, and severe pain in patients with chronic noncancer pain uncontrolled by other mu opioid receptor agonists.

With empirical confirmation, levorphanol has potential as first-line or second-line therapy for these indications, but little research has been published on this drug [46, 49, , ]. The brand-name drug Levo-Dromoran is discontinued, and no parenteral form is available. The sole available dose and formulation for levorphanol is an oral 2-mg tablet []. As a generic drug, levorphanol has not been promoted or marketed []. Roxane Pharmaceuticals stopped manufacturing levorphanol in Shortly thereafter, Sentynl Therapeutics, Inc.

Fentanyl and Analogs Fentanyl Duragesic is a phenylpiperidine-class opioid and is structurally similar to meperidine. Fentanyl was first synthesized in Belgium in the late s and introduced to the U. Other fentanyl analogues were subsequently introduced, including alfentanil, an ultra-short acting 5 to 10 minutes analgesic; sufentanil, an exceptionally potent analgesic 1, times more potent than morphine for use in cardiac surgery; and remifentanil, with similar potency to fentanyl and ultra-short duration of 3 to 10 minutes [].

Fentanyl has an analgesic potency 80 to times that of morphine. The highly lipophilic nature of the molecule allows rapid blood-brain barrier penetration and quick onset of action two to three minutes with IV administration. Primary clinical effect comes from mu receptor agonist activity and to a lesser extent from kappa and delta receptor activity [].

The pharmacologic profiles of fentanyl and its congeners sufentanil, remifentanil, and alfentanil are similar to other mu-receptor agonists, although fentanyl produces fewer side effects of sedation, nausea and vomiting, urinary retention, and pruritus than morphine or hydromorphone []. The fentanyls are distinguished from other mu opioid receptor agonists by shorter time to peak analgesic effect, rapid termination of effect after small doses, and relative cardiovascular stability, making them very popular for surgical use.

The respiratory depression potential is similar to other mu receptor agonists, with a more rapid onset []. Fentanyl formulations include several transmucosal and buccal preparations for rapid-onset analgesia in breakthrough pain, and a transdermal preparation for sustained analgesia in chronic pain. Transmucosal immediate-release fentanyl formulations are approved by the FDA for use in breakthrough pain.

Transdermal fentanyl was developed to circumvent unsuitability for oral use and is indicated for continuous sustained-release analgesia in the treatment of chronic pain []. With initial use, the 6- to hour lag time from application to onset of action requires the use of short-acting opioids for analgesic coverage and for breakthrough pain; morphine, tapentadol, or oxycodone are preferred. Steady state is usually achieved in three to six days. With patch removal, a subcutaneous reservoir remains, and up to 24 hours is usually needed for drug clearance [16, ].

Tramadol Research efforts into mechanisms of pain relief during the s focused on centrally mediated monoamine transmission and its influence on chronic and neuropathic pain. Clinical evidence demonstrated that increasing the extracellular concentrations of serotonin and norepinephrine in descending pain inhibitory pathways produced an analgesic effect.

Norepinephrine is the primary monoamine contributor to pain signal attenuation and is especially useful in neuropathic pain. Combining an opioid agonist with a monoamine reuptake inhibitor was hypothesized to produce opioid-sparing effects, increased pain control, and decreased adverse effects. These efforts led to the development of tramadol and tapentadol [49]. Tramadol Ultram, ConZip is a synthetic codeine analog from the aminocyclohexanol structural group and a racemic compound.

Tramadol has greater efficacy in neuropathic than nociceptive pain. Monoamine reuptake inhibition accounts for tramadol's efficacy in neuropathic pain [].

The primary metabolite, O-desmethyltramadol, has higher mu opioid receptor affinity and two to four times greater analgesic potency than the parent drug. Tramadol is as effective as morphine in mild-moderate pain. Tramadol has lower abuse potential than other opioids but is associated with the significant adverse drug reactions of serotonin syndrome and seizures. Seizure risk is elevated by concurrent use of selective serotonin reuptake inhibitors SSRIs , tricyclic antidepressants TCAs , cyclobenzaprine and other tricyclic compounds, other opioids, neuroleptics, and certain other drugs.

Tramadol should not be used within 14 days of monoamine oxidase inhibitors MAOIs , as this increases risk of seizures or serotonin syndrome [16]. Tapentadol Tapentadol Nucynta is a novel synthetic opioid structurally related to tramadol that was approved in It was intentionally designed to overcome the barriers to efficacy associated with tramadol, such as the potential risk for serotonin syndrome [49]. Tapentadol has 18 times less affinity for mu opioid receptor than morphine and is 5 times less potent than oxycodone i.

Time to maximum serum concentration is achieved in 1. Tapentadol has no active metabolites and primarily undergoes hepatic metabolism via phase II conjugation. Tapentadol selectively inhibits norepinephrine reuptake with affinity and potency comparable to venlafaxine, which increases efficacy and avoids the potential risk for serotonin syndrome.

Analgesic tolerance develops at significantly lower rates with tapentadol than with morphine. It has a low risk for drug interactions, does not depend on metabolic activation for efficacy, and shows a lower incidence in adverse GI effects such as nausea, vomiting, and constipation relative to other opioids [49, ]. Tapentadol is not recommended in patients with severe renal or hepatic impairment, because studies are lacking in these patient populations [].

Meperidine Meperidine Demerol, Meperitab is a synthetic phenylpiperidine derivative with weak mu and kappa receptor agonist activity. It has roughly one-tenth the potency of morphine. The structural similarity to atropine is consistent with its original development as an anti-muscarinic agent. The effects are similar, but not identical, to morphine, with shorter analgesic duration and less antitussive and antidiarrheal efficacy.

In equivalent analgesic doses, meperidine produces comparable sedation and respiratory depression and possibly greater euphoria than morphine, although some patients experience dysphoria. Pharmacologic differences from morphine include increased risk for tachycardia and dry mouth and less biliary tract spasm and miosis. Meperidine may significantly decrease blood pressure, especially when administered to elderly or hypovolemic patients [, ]. The short analgesic duration 2. Accumulation of the neurotoxic metabolite normeperidine contraindicates its use for longer than 48 hours or at doses of mg or greater over 24 hours in any context.

Normeperidine accumulation is especially likely in patients with impaired renal function. The neuroexcitatory properties of this metabolite can cause tremors, muscle twitches, delirium, or seizures; multifocal myoclonus develops before seizures and can serve as a warning sign. Normeperidine toxicity is not reversible with naloxone. Administration of meperidine to patients receiving MAOIs can lead to profound and possibly fatal autonomic instability [16, , ].

Clinical use of meperidine has declined into virtual disuse in recent years []. Propoxyphene Propoxyphene Darvon, Darvocet was first marketed in to treat mild-to-moderate pain. Propoxyphene primarily binds to mu opioid receptors to produce mild analgesia, with potency one-half to one-third that of codeine [16]. Propoxyphene also became a popular drug of abuse. In , the FDA requested the removal of propoxyphene from the U. This drug is no longer available domestically. Levo-Alpha-Acetylmethadol Levo-alpha-acetylmethadol LAAM is a synthetic mu opioid receptor agonist closely related to methadone, but with a longer duration of action 48 to 72 hours.

LAAM was originally developed by German chemists in and as early as was identified as an agent that could prevent opioid withdrawal symptoms for more than 72 hours.

In , the FDA approved LAAM for the treatment of opioid addiction, with the intent to build on the strengths and improve on the drawbacks of methadone [, ]. However, concerns over cardiovascular toxicity and subsequent under-utilization led to its withdrawal from the market in by the manufacturer, and LAAM is no longer commercially available in the United States []. Buprenorphine is the only commercially available partial agonist in the United States.

Buprenorphine Buprenorphine Belbuca, Suboxone, Subutex, Butrans is a semi-synthetic opioid first derived from thebaine in , initially as an alternative to methadone therapy for heroin addiction []. Injectable buprenorphine Buprenex was approved in for acute pain, and two sublingual formulations Suboxone and Subutex were approved for treating opioid addiction in [49]. The buprenorphine transdermal system was approved by the FDA in for the management of moderate-to-severe chronic pain in patients requiring continuous opioid analgesia for an extended time period.

More recently, buprenorphine buccal film Belbuca was approved for the same indication. The transdermal and buccal products were developed to overcome the very low oral bioavailability resulting from substantial first-pass intestinal and hepatic metabolism []. The mu opioid receptor-binding kinetics of buprenorphine are unique.

This receptor saturation is particularly important with buprenorphine, because its high affinity and robust binding capacity make displacement by naloxone difficult or impossible. The relative resistance to naloxone antagonism requires higher doses for successful reversal [49]. The analgesic properties of buprenorphine mostly originate from mu opioid receptor interaction with high binding affinity and low efficacy, yielding partial agonist effects.

Prolonged analgesia can be achieved with buprenorphine from its highly lipophilic properties and prolonged receptor occupancy. It may have superior efficacy in neuropathic pain due to its pharmacologic profile and has also shown anti-hyperalgesic effects [, ]. A high-dose 15 mg analgesic ceiling effect can occur, but this dose level is infrequent with analgesic use [, ].

Buprenorphine may act as a mu opioid receptor antagonist at high doses []. After application of the transdermal patch, plasma concentrations steadily increase, and the minimum effective analgesic dose is reached more rapidly with higher-dose patches. Steady state is reached after the third consecutive application. Effective plasma levels occur within 12 to 24 hours and last for 72 hours. It takes 60 hours to reach maximum concentration.

Transdermal buprenorphine has a maximum dose limited to 20 mcg per hour due to the potential for prolonged QTc wave interval at higher doses [16, ]. Buprenorphine possesses a dose-ceiling effect for respiratory depression, reducing the likelihood of this potentially fatal consequence. For example, once a user on the affected systems MacOS or Linux navigates to a peculiarly crafted web page with the file: By connecting to the page directly, the Tor browser does not go through its relay network.

Windows users are not affected In the response that accompanied the security fix, Tor developers further acknowledged the critical flaw on Linux and Mac systems, and confirmed it does not affect Windows users. The team also stated that users running Tor on the Tails OS and the sandboxed still alpha-stage version of the Tor browser are not affected.

Although no harm has been caused at the time of writing, they say an attacker can perform reverse engineering on the Tor browser to detect the patched code. They noted that well-versed programmers could easily understand how the TorMoil bug occurs, and they could potentially create an exploit for it as well.

Although Tor developers said there is no evidence that the TorMoil flaw is being exploited in the wild, researchers choose to keep details of the flaw classified over concerns of the security and privacy of Tor browser users. The exact bug details will only be revealed when a permanent fix has been released to effectively stop the potential leak of IP addresses. However, Tor advises users to assume that their real IP addresses may have been exposed or might leak in the future, and they should upgrade to the latest versions as soon as possible.

While users on the stable version of the browser for Linux and MacOS have been updated to Tor version 7. Other features include secure naming systems, improved guard algorithms, statistics, blockchain support, mixed-latency routing, virtual reality interface and artificial intelligence logic. These features are set to build on the Tor 0. This version supports next-generation onion services, following four years of development. The new releases are all part of the larger 0. The series will, by default, replace the legacy onion system that has been in existence for over ten years.

Still, users should know that Tor vulnerabilities are continuing to arise over time. This provides double protection and keeps you safe from any privacy and security-related threats that may find your device.

Dream Market has confirmed a hardware malfunction in their escrow system, which is preventing some users from accessing their money. The popular dark web trading site Dream Market has been reportedly having issues with its escrow account system, which is subsequently preventing some users from accessing and withdrawing their funds.

The issue is said to have resulted from a hardware malfunction. Confirming this predicament, one user claimed he received the following message while attempting to complete a transaction: They believe that this concern is not as much about early finalizing as is now the common perception—users have been attempting to withdraw money from their individual escrow accounts on time but Dream Market will still not allow them to do so. The story is similar for all the affected users.

In truth, some claim that those running Dream Market might as well be typical scammers, even going further to caution potential customers from depositing their funds on the site.

The frustration is widespread indeed. One client, for instance, claimed that while he attempted to dispute an order to reacquire his funds, the dispute button—normally present—was unavailable in this instance. This resulted in the auto-finalization of the order in as little as 14 days. In his final comments written on Reddit, he expressed his lack of understanding on exactly what was unfolding. Word around town is that Dream Market is, in fact, orchestrating an exclusive exit scam.

Speculation was particularly rampant after the site experienced an outage earlier, lasting only a few hours. Users feared that the market was seized by law During this time, many users worried the market had been seized by law enforcement. But this was before the escrow payment system was reported to be non-functional. Nonetheless, this appears to be a recurrent issue since a few months back when other account holders also raised a similar concern on Reddit.

These displeased holders are urging all account holders to immediately withdraw all their Bitcoin funds from their respective accounts. According to them, the faster they do it, the better and safer it is for them.

This hardware crash is apparently sparing no one, with both big and small vendors suffering the same predicament. Astoundingly, even holders with a 4. This, however, goes to dispel the idea that the only casualties are the low-rated accounts. As is now commonly perceived, the notion that Dream is purportedly delaying the release of funds escrow coins to users in order to pull a typical exit scam seems to have settled well with many of the traders.

In the end, traders can only wait to see what unfolds. Ever since two of the leading darknet marketplaces shut down, massive transitions have been taking place on the dark web. Since late July, Dream Market and a few other counterparts have experienced a 28 percent surge in overall traffic.

Dream Market in particular now features more than 98, postings. Speculations were rife that the highly popular darknet market AlphaBay had been seized by law authorities when it disappeared in July, and to the disappointment of millions of dark web users, the rumors turned out to be true.

With transactions worth hundreds of thousands of dollars down the drain, life has been tough on the darknet. Writing on the Wall Ever since the U. Operations were also conducted in Thailand and Lithuania. The suspected founder, Alexander Cazes, was arrested on July 5. A week later, he was found dead in prison. Authorities state that Cazes committed suicide. Effectively three days later, a number of Dutch authorities had complete control over Hansa.

If reports are to be believed, Hansa was secretly under the scanner for as long as a month after the initial capture. Dream Market Emerges as New Leader Born out of the ashes of Silk Road, like many of its other counterparts, Dream Market now features the highest number of listings—98, and counting. It is also one of the oldest marketplaces on the darknet, with a loyal user base.

Of course, certain goods have taken a substantial hit and likely will not see the light of day until the dust settles. Purdue Pharma — a privately held company based in Stamford, Connecticut, developed the prescription painkiller OxyContin. Upon its release in , OxyContin was hailed as a medical breakthrough, a long-lasting narcotic that could help patients suffering from moderate to severe pain. The drug became a blockbuster, and has reportedly generated some thirty-five billion dollars in revenue for Purdue.

In addition, oxycodone is subject to national laws that differ by country. Other provinces have proposed similar legislation, while some, such as Nova Scotia, have legislation already in effect for monitoring prescription drug use.

This was a first for any province to delist a drug based on addictive properties. The new law prohibits prescriptions for OxyNeo except to certain patients under the Exceptional Access Program including palliative care and in other extenuating circumstances.

Patients already prescribed oxycodone will receive coverage for an additional year for OxyNeo, and after that, it will be disallowed unless designated under the exceptional access program. The new formulation, OxyNeo, is intended to be preventative in this regard and retain its effectiveness as a painkiller.

Since introducing its Narcotics Safety and Awareness Act, Ontario has committed to focusing on drug addiction, particularly in the monitoring and identification of problem opioid prescriptions, as well as the education of patients, doctors, and pharmacists.

Because laws are largely provincially regulated, many speculate a national strategy is needed to prevent smuggling across provincial borders from jurisdictions with looser restrictions.

In June , then federal Minister of Health Rona Ambrose announced that within three years all oxycodone products sold in Canada would need to be tamper-resistant. Some experts warned that the generic product manufacturers may not have the technology to achieve that goal, possibly giving Purdue Pharma a monopoly on this opiate.

Claimants argue the pharmaceutical manufacturers did not meet a standard of care and were negligent in doing so.

Chronic pain unresponsive to opioid dose escalation may oxycodone tolerance, but it may also be the result of disease progression, non-opioid responsive pain syndromes, or opioid-induced hyperalgesia.
